点击后Android PopupWindow按钮消失

Question

我在 Android上的PopupWindow遇到了一个非常令人沮丧的问题。我已经实现了我自己的类，它继承了PopupWindow并实现了 OnClickListener。

添加带有自定义选择器的按钮背景后，问题开始了。单击按钮后，此背景不断消失（启动新活动并关闭弹出窗口）。“聚焦并单击”后它不会消失，只有“快速单击”后才会消失。

任何想法/建议都会非常受欢迎！

public class TestPopup extends PopupWindow implements OnClickListener

protected LayoutInflater inflater;
protected Activity caller;
protected View popup;
protected View layout;

public TestPopup(Activity activity) {
    super(activity);
    popup = inflater.inflate(R.layout.popup, (ViewGroup) caller.findViewById(R.id.contentLayout));
    layout = popup.findViewById(R.id.layout);

    popup.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

    Display display = caller.getWindowManager().getDefaultDisplay();
    setHeight(display.getHeight());
    setWidth(display.getWidth());
    setFocusable(true);
    setContentView(popup);

    // fix to allow Popup to be clickable!
    setBackgroundDrawable(new BitmapDrawable());

    popup.setOnClickListener(this);
    popup.findViewById(R.id.addButton).setOnClickListener(this);
    popup.findViewById(R.id.deleteButton).setOnClickListener(this);
}

public void onClick(View v) {
    Intent intent = null;
    if (v.getId() == R.id.addButton) {
        intent = new Intent(caller, AddActivity.class);
        intent.putExtra(AddActivity.ACTION_ADD, true);
    } else if (v.getId() == R.id.deleteButton) {
        intent = new Intent(caller, AddActivity.class);
        intent.putExtra(AddActivity.ACTION_DELETE, true);
    }

    if (intent != null) {
        caller.startActivity(intent);
    }

    TestPopup.this.dismiss();
}

一种解决方案是调用popup.invalidate(); 在关闭弹出窗口之前。
