我只在一台设备上以严格模式崩溃（LG G2 Android 4.2.2）。这发生在我点击微调器（dropDown）然后点击列表下拉列表外的区域然后离开父活动。

Answer 1

在onPause()方法中取消注册您的接收器。您必须在onResume()中注册接收器并在onPause()中取消注册以防止内存泄漏

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(yourReceiver);
}

@Override
protected void onPause() {
    super.onPause();
    unregisterReceiver(yourReceiver);
}

ListPopupWindow：你是否错过了对unregisterReceiver（）的调用
