Android 纯代码布局编写手游sdk

前语 ：

最近由于公司需求 上Google被查的很严， 所以就想着把代码重构 然后写布局也改成用代码写，所以就写了一个demo 然后我这边就想着 分享给各位同学

具体完成：

• 精简View的Base封装

-### 头部导航封装

• 标题文字

ls.gravity = Gravity.CENTER;
RelativeLayout titleLayout = new RelativeLayout(getContext());
//增加标题
mTitleTv = getTitleTv(getTitle());
titleLayout.addView(mTitleTv, ls);

• 左侧封闭

//封闭按钮
if(!TextUtils.isEmpty(backimagesrc)){
    backimage = new ImageView(getContext());
    //backimage.setPadding(_10dp, _5dp, _10dp, _5dp);
   //backimage.setBackground(DrawableUtils.createShape(1, C_COMFIRM));
    backimage.setImageResource(ImmpResourceUtil.getDrawableId(mContext,
            backimagesrc));
    RelativeLayout.LayoutParams backrl = new RelativeLayout.LayoutParams(_20dp, _20dp);
    backrl.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    backrl.leftMargin=_10dp;
    backrl.topMargin=_10dp;
    titleLayout.addView(backimage, backrl);
    backimage.setVisibility(View.VISIBLE);
    backimage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dismiss();
        }
    });
}

• 右侧封闭

// 右侧按钮
if(!TextUtils.isEmpty(closeimagesrc)){
    closeimage = new ImageView(getContext());
    closeimage.setPadding(_10dp, _5dp, _10dp, _5dp);
    closeimage.setImageResource(ImmpResourceUtil.getDrawableId(mContext,
            closeimagesrc));
    RelativeLayout.LayoutParams closerl = new RelativeLayout.LayoutParams(_20dp, _20dp);
    closerl.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    closerl.rightMargin = _10dp;
    closerl.topMargin = _10dp;
    titleLayout.addView(closeimage, closerl);
    closeimage.setVisibility(View.VISIBLE);
    closeimage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dismiss();
        }
    });
}

• 增加分割线和增加view到layout

ls = new LinearLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT);
ls.gravity = Gravity.CENTER;
mParentView.addView(titleLayout, ls);
ls = new LinearLayout.LayoutParams(dp(25), dp(25));
ls.gravity = Gravity.CENTER;
ls.leftMargin = dp(5);
ls.topMargin = dp(5);
//增加分割线
mParentView.addView(addLine(getContext()), new LinearLayout.LayoutParams(MATCH_PARENT, dp(1)));//增加分割线
//增加内容
ls = new LinearLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT);
ls.gravity = Gravity.CENTER;
ls.weight = 1;
mContentView = new LinearLayout(getContext());
mContentView.setOrientation(LinearLayout.VERTICAL);
mContentView.setGravity(Gravity.CENTER);
mContentView.setPadding(_10dp, 0, _10dp, _10dp);
setCanceledOnTouchOutside(false);
// setCancelable(false);
mParentView.addView(mContentView, ls);
setContentView(mParentView, new LinearLayout.LayoutParams(MATCH_PARENT, MATCH_PARENT));

• 完好SimpleBaseDialog代码

• 注册界面显现调用

SimpleregisterDialog simpleregisterDialog=new SimpleregisterDialog(context,"ddsrwc_back_icon");
simpleregisterDialog.show();

效果图

最后总结：

安卓的纯代码布局比照iOS纯代码确实要费事很多 但是也是能够写 弊端就是无法可视化预览 写起来功率低 优点就是缺少了xml 布局编译时分解析 然后再sdk打包的时分只需要打包java 代码即可 我们在坐马甲包的时分也能够做出更多差异化， 由于xml布局我们无法做过多的混杂和差异化。如果你觉得文章还不错费事给我三连 关注点赞和转发 谢谢
