我已经检查过这个链接，但它提到了长点击。但是在单击自定义对话框的按钮后我正面临这个问题。我已经把我的代码贴在这里了。谁能帮我避免这个错误。
ibtnCancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.w("DemoDvicetracker", etConfirmPassword
.getText().toString());
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(
etConfirmPassword.getWindowToken(), 0);
passwordPopup.dismiss();
}
});

this is not a problem related to your code, but related to S4 android version. Same question has been posed on stackoverflow : sendUserActionEvent() is null
这不是与您的代码相关的问题，而是与 S4 android 版本相关的问题。在 stackoverflow 上也提出了同样的问题：sendUserActionEvent() 为空
So, just ignore it ;)
所以，忽略它;)

In my case I was using al this intent flags together to intent the activity:
在我的情况下，我将所有意图标志一起用于意图活动：
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
Just left the clear_top flag and it solved the problem:
刚刚离开 clear_top 标志，它解决了问题：
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
