获取view的坐标 宽高 以及 view 转drawable

ViewTreeObserver vto = container.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
   
    @Override public void onGlobalLayout() {
    container.getViewTreeObserver() .removeGlobalOnLayoutListener(this);
    width = container.getWidth();
    heigh = container.getHeight();
    int[] xy = new int[2];
    container.getLocationOnScreen(xy);
    x = xy[0];
    y = xy[1];
    } });

 

 

/**
  * 根据view 返回drawable 对象

  * @return

 public Drawable getDrawable(View view){
  int w = screenWidth /2;
  int h = screenHeight /2;
  
   Bitmap b = Bitmap.createBitmap(w, h,   Bitmap.Config.ARGB_8888); 
   Canvas c = new Canvas(b); 
   // c.translate(-view.getScrollX(), -view.getScrollY());
