1.简介
学习下settings》system》reset options相关
2.reset options
2.1.system_dashboard_fragment.xml
<Preference
android:key="reset_dashboard"
android:title="@string/reset_dashboard_title"
android:icon="@drawable/ic_restore"
android:order="-30"
android:fragment="com.android.settings.system.ResetDashboardFragment"
settings:controller="com.android.settings.system.ResetPreferenceController"/>
>1.ResetPreferenceController
reset options是否可用是装备里的字段操控的
public int getAvailabilityStatus() {
return mContext.getResources().getBoolean(R.bool.config_show_reset_dashboard)
? AVAILABLE : UNSUPPORTED_ON_DEVICE;
}
2.2.ResetDashboardFragment
这个便是点击reset options今后跳转的页面
>1.reset_dashboard_fragment.xml
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:settings="http://schemas.android.com/apk/res-auto"
android:title="@string/reset_dashboard_title">
<!-- Network reset ,跳转到fragment见末节3-->

settings:userRestriction="no_factory_reset"
settings:useAdminDisabledSummary="true"
android:fragment="com.android.settings.MainClear" />
</PreferenceScreen>
>2.buildPreferenceControllers
相关的controller,详细见2.3
private static List<AbstractPreferenceController> buildPreferenceControllers(Context context,
Lifecycle lifecycle) {
final List<AbstractPreferenceController> controllers = new ArrayList<>();
controllers.add(new NetworkResetPreferenceController(context));
controllers.add(new FactoryResetPreferenceController(context));
controllers.add(new ResetAppPrefPreferenceController(context, lifecycle));
return controllers;
}
2.3.Controller
>1.NetworkResetPreferenceController
网络重置，操控是否可用
public NetworkResetPreferenceController(Context context) {
super(context);
mRestrictionChecker = new NetworkResetRestrictionChecker(context);
}
@Override
public boolean isAvailable() {
return !mRestrictionChecker.hasUserRestriction();
}
>2.ResetAppPrefPreferenceController
重置app的操控器
public boolean handlePreferenceTreeClick(Preference preference) {
if (!TextUtils.equals(preference.getKey(), getPreferenceKey())) {
return false;
}
mResetAppsHelper.buildResetDialog();//显现一个dialog
return true;
}
@Override
public boolean isAvailable() {
return true;//默许可用
}
//点击是弹出一个对话框
void buildResetDialog() {
if (mResetDialog == null) {

.setTitle(R.string.reset_app_preferences_title)
.setMessage(R.string.reset_app_preferences_desc)
.setPositiveButton(R.string.reset_app_preferences_button, this)
.setNegativeButton(R.string.cancel, null)
.setOnDismissListener(this)
.show();
}
}
>3.FactoryResetPreferenceController
恢复出厂设置的操控器
public FactoryResetPreferenceController(Context context) {
super(context);
mUm = (UserManager) context.getSystemService(Context.USER_SERVICE);
}
/**体系用户或者测试用户可用*/
@Override
public boolean isAvailable() {
return mUm.isAdminUser() || Utils.isDemoUser(mContext);
}
@Override

//点击跳转到其他activity,见末节4
final Intent intent = new Intent(mContext, Settings.FactoryResetActivity.class);
mContext.startActivity(intent);
return true;
}
return false;
}
>4.EraseEuiccDataController
这个是sim卡相关的，有对应的功用才可见
public boolean handlePreferenceTreeClick(Preference preference) {
if (!TextUtils.equals(preference.getKey(), getPreferenceKey())) {
return false;
}
//选项的点击事情
EraseEuiccDataDialogFragment.show(mHostFragment);
return true;
}

6.GlifLayout
external/setupdesign/main/src/com/google/android/setupdesign/GlifLayout.java
- 这个是末节5用的根布局，自界说的帧布局，看下为啥有时候是全屏的，有时候是带边框非全屏的
- 打印的布局结构为啥和5.1.1不一样，看下这个自界说控件是怎么替换布局的。
public class GlifLayout extends PartnerCustomizationLayout {
6.1.init
结构方法里调用，这儿便是处理第三方色彩，padding的
private void init(AttributeSet attrs, int defStyleAttr) {
if (isInEditMode()) {
return;
}
TypedArray a =
getContext().obtainStyledAttributes(attrs, R.styleable.SudGlifLayout, defStyleAttr, 0);
boolean usePartnerHeavyTheme =
a.getBoolean(R.styleable.SudGlifLayout_sudUsePartnerHeavyTheme, false);
applyPartnerHeavyThemeResource = shouldApplyPartnerResource() && usePartnerHeavyTheme;
//注册需求的目标

final RequireScrollMixin requireScrollMixin = new RequireScrollMixin(this);
registerMixin(RequireScrollMixin.class, requireScrollMixin);
//..
ColorStateList primaryColor = a.getColorStateList(R.styleable.SudGlifLayout_sudColorPrimary);
if (primaryColor != null) {
//见6.5
setPrimaryColor(primaryColor);
}
if (shouldApplyPartnerHeavyThemeResource()) {
//rootView色彩设置
updateContentBackgroundColorWithPartnerConfig();
}
View view = findManagedViewById(R.id.sud_layout_content);
if (view != null) {
//见7.2，是否运用第三方的资源
if (shouldApplyPartnerResource()) {
//设置第三方的padding，首要是左右padding
LayoutStyler.applyPartnerCustomizationExtraPaddingStyle(view);
}
if (!(this instanceof GlifPreferenceLayout)) {
//top padding设置
tryApplyPartnerCustomizationContentPaddingTopStyle(view);
}
}
//依据margion调整padding
updateLandscapeMiddleHorizontalSpacing();
//布景色彩设置,见6.5以及6.4，便是自己的第一个child的布景
ColorStateList backgroundColor =
a.getColorStateList(R.styleable.SudGlifLayout_sudBackgroundBaseColor);
setBackgroundBaseColor(backgroundColor);
//见6.5
boolean backgroundPatterned =
a.getBoolean(R.styleable.SudGlifLayout_sudBackgroundPatterned, true);
setBackgroundPatterned(backgroundPatterned);
final int stickyHeader = a.getResourceId(R.styleable.SudGlifLayout_sudStickyHeader, 0);
if (stickyHeader != 0) {
inflateStickyHeader(stickyHeader);
}
a.recycle();
}
6.2.onInflateTemplate
这儿界说的模板layout带主题
protected View onInflateTemplate(LayoutInflater inflater, @LayoutRes int template) {
if (template == 0) {
//，默许运用的模板，不同尺度指向不同的布局，详细在layout.xml里声明的,见弥补1
template = R.layout.sud_glif_template;
}
return inflateTemplate(inflater, R.style.SudThemeGlif_Light, template);
}
>1.sud_glif_template
咱们是平板，所以直接看大尺度的即可
#values
<item name="sud_glif_template" type="layout">@layout/sud_glif_template_compact</item>
#values-sw600dp
<item name="sud_glif_template" type="layout">@layout/sud_glif_template_card</item>

6.3.findContainer
这个容器的作用：把GlifLayout里本来的内容放到这个容器里
protected ViewGroup findContainer(int containerId) {
if (containerId == 0) {
containerId = R.id.sud_layout_content;
}
return super.findContainer(containerId);
}
6.4.updateBackground
用到的当地见6.5
private void updateBackground() {
//见6.2.2布局,GlifLayout里替换的根布局便是这个
final View patternBg = findManagedViewById(R.id.suc_layout_status);
if (patternBg != null) {
int backgroundColor = 0;
if (backgroundBaseColor != null) {
backgroundColor = backgroundBaseColor.getDefaultColor();
} else if (primaryColor != null) {
backgroundColor = primaryColor.getDefaultColor();
}
Drawable background =
backgroundPatterned
? new GlifPatternDrawable(backgroundColor)
: new ColorDrawable(backgroundColor);
//设置statusbar布景,便是patternBg，详细能够去StatusBarMixin查看
getMixin(StatusBarMixin.class).setStatusBarBackground(background);
}
}
6.5.color设置
public void setPrimaryColor(@NonNull ColorStateList color) {
primaryColor = color;
updateBackground();
getMixin(ProgressBarMixin.class).setColor(color);
}
public void setBackgroundBaseColor(@Nullable ColorStateList color) {
backgroundBaseColor = color;
updateBackground();
}
/**
* Sets whether the background should be {@link GlifPatternDrawable}. If {@code false}, the
* background will be a solid color.
*/
public void setBackgroundPatterned(boolean patterned) {

updateBackground();
}
7.PartnerCustomizationLayout
external/setupcompat/main/java/com/google/android/setupcompat/PartnerCustomizationLayout.java
public class PartnerCustomizationLayout extends TemplateLayout {
7.1.init
结构方法里会调用
private void init(AttributeSet attrs, int defStyleAttr) {
if (isInEditMode()) {
return;
}
TypedArray a =
getContext()
.obtainStyledAttributes(
attrs, R.styleable.SucPartnerCustomizationLayout, defStyleAttr, 0);
boolean layoutFullscreen =
a.getBoolean(R.styleable.SucPartnerCustomizationLayout_sucLayoutFullscreen, true);
a.recycle();
if (VERSION.SDK_INT >= VERSION_CODES.LOLLIPOP && layoutFullscreen) {
setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
//这儿注册了3个目标
registerMixin(
StatusBarMixin.class, new StatusBarMixin(this, activity.getWindow(), attrs, defStyleAttr));
registerMixin(SystemNavBarMixin.class, new SystemNavBarMixin(this, activity.getWindow()));
registerMixin(FooterBarMixin.class, new FooterBarMixin(this, attrs, defStyleAttr));

activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}
7.2.shouldApplyPartnerResource
是否运用合作者的资源装备
/** Returns if the current layout/activity applies partner customized configurations or not. */
public boolean shouldApplyPartnerResource() {
if (!enablePartnerResourceLoading()) {//默许为true，见弥补1
return false;
}
if (!usePartnerResourceAttr) {//见7.3
return false;
}
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {
return false;
}
if (!PartnerConfigHelper.get(getContext()).isAvailable()) {
return false;
}
return true;
}
>1.enablePartnerResourceLoading
protected boolean enablePartnerResourceLoading() {
return true;
}
7.3.onBeforeTemplateInflated
protected void onBeforeTemplateInflated(AttributeSet attrs, int defStyleAttr) {
usePartnerResourceAttr = true;
activity = lookupActivityFromContext(getContext());
//是否是setup流程
boolean isSetupFlow = WizardManagerHelper.isAnySetupWizard(activity.getIntent());
TypedArray a =
getContext()
.obtainStyledAttributes(
attrs, R.styleable.SucPartnerCustomizationLayout, defStyleAttr, 0);
//setup流程中，或者布局装备里sucUsePartnerResource为true
usePartnerResourceAttr =
isSetupFlow
|| a.getBoolean(R.styleable.SucPartnerCustomizationLayout_sucUsePartnerResource, true);
useDynamicColor = a.hasValue(R.styleable.SucPartnerCustomizationLayout_sucFullDynamicColor);
useFullDynamicColorAttr =
a.getBoolean(R.styleable.SucPartnerCustomizationLayout_sucFullDynamicColor, false);
a.recycle();
}
7.4.PartnerConfigHelper.java
>1.isAvailable
bundle不为空就回来true
public boolean isAvailable() {
return resultBundle != null && !resultBundle.isEmpty();
}
>2.getPartnerConfigBundle
bundle数据来历是谷歌的setupwizard的contentProvider
private void getPartnerConfigBundle(Context context) {
if (resultBundle == null || resultBundle.isEmpty()) {
try {
resultBundle =
context
.getContentResolver()
.call(
getContentUri(),
SUW_GET_PARTNER_CONFIG_METHOD,
/* arg= */ null,
/* extras= */ null);
partnerResourceCache.clear();
}
}
}
public static final String SUW_GET_PARTNER_CONFIG_METHOD = "getOverlayConfig";
public static final String SUW_AUTHORITY = "com.google.android.setupwizard.partner";
static Uri getContentUri() {
return new Uri.Builder()
.scheme(ContentResolver.SCHEME_CONTENT)
.authority(SUW_AUTHORITY)
.build();
}
8.TemplateLayout
external/setupcompat/main/java/com/google/android/setupcompat/internal/TemplateLayout.java
public class TemplateLayout extends FrameLayout {
8.1.init
结构方法里调用
private void init(int template, int containerId, AttributeSet attrs, int defStyleAttr) {
final TypedArray a =
getContext().obtainStyledAttributes(attrs, R.styleable.SucTemplateLayout, defStyleAttr, 0);
if (template == 0) {
template = a.getResourceId(R.styleable.SucTemplateLayout_android_layout, 0);
}
if (containerId == 0) {
containerId = a.getResourceId(R.styleable.SucTemplateLayout_sucContainer, 0);
}
onBeforeTemplateInflated(attrs, defStyleAttr);
inflateTemplate(template, containerId);
a.recycle();
}
>1.inflateTemplate
两个参数在子类都覆写了，如果为0，会给与默许值，见末节6.2,6.3
private void inflateTemplate(int templateResource, int containerId) {
final LayoutInflater inflater = LayoutInflater.from(getContext());
final View templateRoot = onInflateTemplate(inflater, templateResource);
//增加到当前容器里
addViewInternal(templateRoot);
//查找容器
container = findContainer(containerId);
if (container == null) {
throw new IllegalArgumentException("Container cannot be null in TemplateLayout");
}
onTemplateInflated();
}
依据template加载对应的布局view，子类重写了，给与默许的template，以及theme，见6.2
protected View onInflateTemplate(LayoutInflater inflater, @LayoutRes int template) {
return inflateTemplate(inflater, 0, template);
}
protected final View inflateTemplate(
LayoutInflater inflater, @StyleRes int fallbackTheme, @LayoutRes int template) {
if (template == 0) {
throw new IllegalArgumentException("android:layout not specified for TemplateLayout");
}
if (fallbackTheme != 0) {
inflater =
LayoutInflater.from(new FallbackThemeWrapper(inflater.getContext(), fallbackTheme));
}
return inflater.inflate(template, this, false);
}
8.2.addView
init方法里会获取container，能够看到终究的child实际加到这个容器里了，这儿完成了替换，
public void addView(View child, int index, ViewGroup.LayoutParams params) {
container.addView(child, index, params);
}
8.3.mixins
private final Map<Class<? extends Mixin>, Mixin> mixins = new HashMap<>();
>1.registerMixin
数据注册见子类末节7.1
protected <M extends Mixin> void registerMixin(Class<M> cls, M mixin) {
mixins.put(cls, mixin);
}
2.getMixin
public <M extends Mixin> M getMixin(Class<M> cls) {
return (M) mixins.get(cls);
}
8.4.总结
- 末节6到8都是GlifLayout布局相关，首要学习下它是怎么替换内部child的
- 首要便是内部自己加载了一套布局作为container，完事add到GlifLayout里，之后把FlifLayout里本来的child放到container里
9.FooterBarMixin
9.1.setPrimaryButton
public void setPrimaryButton(FooterButton footerButton) {
ensureOnMainThread("setPrimaryButton");
ensureFooterInflated();
// Setup button partner config
FooterButtonPartnerConfig footerButtonPartnerConfig =
new FooterButtonPartnerConfig.Builder(footerButton)
.setPartnerTheme(
getPartnerTheme(
footerButton,
/* defaultPartnerTheme= */ R.style.SucPartnerCustomizationButton_Primary,
/* buttonBackgroundColorConfig= */ PartnerConfig
.CONFIG_FOOTER_PRIMARY_BUTTON_BG_COLOR))
.setButtonBackgroundConfig(PartnerConfig.CONFIG_FOOTER_PRIMARY_BUTTON_BG_COLOR)

.setButtonIconConfig(getDrawablePartnerConfig(footerButton.getButtonType()))
.setButtonRadiusConfig(PartnerConfig.CONFIG_FOOTER_BUTTON_RADIUS)
.setButtonRippleColorAlphaConfig(PartnerConfig.CONFIG_FOOTER_BUTTON_RIPPLE_COLOR_ALPHA)

.setButtonMinHeight(PartnerConfig.CONFIG_FOOTER_BUTTON_MIN_HEIGHT)
.setTextTypeFaceConfig(PartnerConfig.CONFIG_FOOTER_BUTTON_FONT_FAMILY)
.setTextStyleConfig(PartnerConfig.CONFIG_FOOTER_BUTTON_TEXT_STYLE)
.build();
FooterActionButton button = inflateButton(footerButton, footerButtonPartnerConfig);
// update information for primary button. Need to update as long as the button inflated.
primaryButtonId = button.getId();
button.setPrimaryButtonStyle(/* isPrimaryButtonStyle= */ true);
primaryButton = footerButton;
primaryButtonPartnerConfigForTesting = footerButtonPartnerConfig;
onFooterButtonInflated(button, footerBarPrimaryBackgroundColor);
onFooterButtonApplyPartnerResource(button, footerButtonPartnerConfig);
// Make sure the position of buttons are correctly and prevent primary button create twice or
// more.
repopulateButtons();
}
9.2.inflateButton
依据footerButton的装备，生成一个FooterActionButton
private FooterActionButton inflateButton(
FooterButton footerButton, FooterButtonPartnerConfig footerButtonPartnerConfig) {
FooterActionButton button =
createThemedButton(context, footerButtonPartnerConfig.getPartnerTheme());
if (Build.VERSION.SDK_INT >= VERSION_CODES.JELLY_BEAN_MR1) {
button.setId(View.generateViewId());
} else {
button.setId(generateViewId());
}
// apply initial configuration into button view.
button.setText(footerButton.getText());
button.setOnClickListener(footerButton);
button.setVisibility(footerButton.getVisibility());
button.setEnabled(footerButton.isEnabled());
button.setFooterButton(footerButton);
footerButton.setOnButtonEventListener(createButtonEventListener(button.getId()));
return button;
}
9.3.onFooterButtonInflated
把按钮增加到容器里
protected void onFooterButtonInflated(Button button, @ColorInt int defaultButtonBackgroundColor) {
if (defaultButtonBackgroundColor != 0) {
FooterButtonStyleUtils.updateButtonBackground(button, defaultButtonBackgroundColor);
}
//见弥补，看下容器哪里来的
buttonContainer.addView(button);
autoSetButtonBarVisibility();
}
9.4.ensureFooterInflated
private LinearLayout ensureFooterInflated() {
if (buttonContainer == null) {
if (footerStub == null) {
throw new IllegalStateException("Footer stub is not found in this template");
}
//见弥补2
buttonContainer = (LinearLayout) inflateFooter(R.layout.suc_footer_button_bar);
onFooterBarInflated(buttonContainer);
onFooterBarApplyPartnerResource(buttonContainer);
}
return buttonContainer;
}
>1.footerStub
public FooterBarMixin(
TemplateLayout layout, @Nullable AttributeSet attrs, @AttrRes int defStyleAttr) {
context = layout.getContext();
//见6.2.3的布局结尾
footerStub = layout.findManagedViewById(R.id.suc_layout_footer);
>2.inflateFooter
protected View inflateFooter(@LayoutRes int footer) {
if (Build.VERSION.SDK_INT >= VERSION_CODES.JELLY_BEAN) {
LayoutInflater inflater =
LayoutInflater.from(
new ContextThemeWrapper(context, R.style.SucPartnerCustomizationButtonBar_Stackable));
footerStub.setLayoutInflater(inflater);
}
footerStub.setLayoutResource(footer);
return footerStub.inflate();
}
9.5.autoSetButtonBarVisibility
按钮的可见性处理
private void autoSetButtonBarVisibility() {
Button primaryButton = getPrimaryButtonView();
Button secondaryButton = getSecondaryButtonView();
boolean primaryVisible = primaryButton != null && primaryButton.getVisibility() == View.VISIBLE;
boolean secondaryVisible =
secondaryButton != null && secondaryButton.getVisibility() == View.VISIBLE;
if (buttonContainer != null) {
buttonContainer.setVisibility(
primaryVisible || secondaryVisible
? View.VISIBLE
: removeFooterBarWhenEmpty ? View.GONE : View.INVISIBLE);
}
}
