我对 Android上的PopupWindow有一个非常令人沮丧的问题。我已经实现了自己的类,它继承了PopupWindow并实现 了 OnClickListener。
使用自定义选择器添加按钮背景后,问题开始。单击按钮(开始新活动并关闭弹出窗口)后,此背景不断消失。“聚焦并单击”后它不会消失,只有在“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();
}
