我在 Android 上遇到了 PopupWindow 的一个非常令人沮丧的问题。我已经实现了我自己的继承 PopupWindow 的类并实现了OnClickListener

使用自定义选择器添加按钮背景后,问题开始出现。单击按钮(开始新 Activity 并关闭弹出窗口)后,此背景不断消失。它不会在“聚焦并点击”后消失,只会在“快速点击”后消失。

如有任何想法/建议,我们将不胜感激!

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();
}

Popup

最佳答案

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