attrs for AlphaMaskLayout

Step1:

在XML中添加

    //your layout here
    //...
    //...

其中android:foreground="#000"就是遮罩层的颜色，不设置则使用默认值#1f1f1f.

//you can also do in java like this:
maskLayout.setAlphaFrom(0);
maskLayout.setAlphaTo(127);
maskLayout.setDuration(600);

Step2:

在activity中调用

//显示
moreBtn.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        View content = LayoutInflater.from(MainActivity.this).inflate(R.layout.popup, null);
        mPopupWindow = new PopupWindow(content, 300, 400);
        mPopupWindow.setFocusable(true);
        mPopupWindow.setOutsideTouchable(true);
        mPopupWindow.setBackgroundDrawable(new ColorDrawable());
        mPopupWindow.showAsDropDown(moreBtn);
        mPopupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
              @Override
              public void onDismiss() {
                maskLayout.hideMask();
              }
        });
        maskLayout.showMask();
      }
});
//监听器
maskLayout.setOnAlphaFinishedListener(new AlphaMaskLayout.OnAlphaFinishedListener() {
            @Override
            public void onShowFinished() {
                Toast.makeText(MainActivity.this, "show finished", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onHideFinished() {
                Toast.makeText(MainActivity.this, "hide finished", Toast.LENGTH_SHORT).show();
            }
        });
