在代码中创建布局的方法

第一种imageView = new ImageView(this);FrameLayout decorView = (FrameLayout) getWindow().getDecorView();decorView.addView(imageView);FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) imageView.getLayoutParams();layoutParams.width = DubDisplay.dip2px(this, 38);layoutParams.height = DubDisplay.dip2px(this, 38);layoutParams.gravity = Gravity.BOTTOM | Gravity.END;layoutParams.setMargins(0, 0, DubDisplay.dip2px(this, 20), DubDisplay.dip2px(this, 20));imageView.setBackgroundResource(R.drawable.slipping_top);imageView.setOnClickListener(new View.OnClickListener() {    @Override    public void onClick(View v) {        user_cash_listview.post(new Runnable() {            @Override            public void run() {                user_cash_listview.requestFocusFromTouch();                user_cash_listview.setSelection(0);            }        });    }});

第二种/*lp = new WindowManager.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,        ViewGroup.LayoutParams.WRAP_CONTENT,        WindowManager.LayoutParams.TYPE_APPLICATION,        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE// 设置为无焦点状态                | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, // 没有边界        PixelFormat.TRANSLUCENT);// 半透明效果lp.gravity = Gravity.BOTTOM;lp.windowAnimations = R.style.bus_view;windowManager.updateViewLayout(view, lp);*/
