我正在尝试在活动结束前显示一个对话框。我显示了对话框，然后按下OK按钮，活动就被关闭了。但我发现窗户漏水了。这是我的密码。
主要活动
@Override
public void onBackPressed(){
FragmentManager fm = getFragmentManager();
if (fm.getBackStackEntryCount() > 0) {
Log.i("MainActivity", "popping backstack");
fm.popBackStack();
} else {
MyAlertDialog dialog=new MyAlertDialog(this);
dialog.displayDialog("Exit", "Do you wish to exit application?",0);
super.onBackPressed();
}
} 对话类
public void displayDialog(String title,String message,final int flag)
{
AlertDialog.Builder builder=new AlertDialog.Builder(context);
builder.setTitle(title)
.setMessage(message);
builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
passIntent(flag);
}
});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog dialog=builder.create();
dialog.show();
}
public void passIntent(int flag)
{
switch(flag)
{
case 0:
((Activity) context).finish();
break;
}
}这是我的错误

错误：
com.android.internal.policy.impl.PhoneWindow$DecorView{26da0ed7 V.E.最初添加的R.....ID 0,0-480,284}
您将得到此错误，因为Dialog在完成Activity后显示。
您的对话框将显示，并调用super.onBackPressed()，这将完成您的活动。
尝尝这个
MyAlertDialog dialog=new MyAlertDialog(this);
dialog.displayDialog("Exit", "Do you wish to exit application?",0);而不是
MyAlertDialog dialog=new MyAlertDialog(this);
dialog.displayDialog("Exit", "Do you wish to exit application?",0);
super.onBackPressed();因此，请删除super.onBackPressed()，然后它将解决您的问题。

您的问题似乎是由于您在显示Activity后立即离开Dialog造成的。
@Override
public void onBackPressed(){
FragmentManager fm = getFragmentManager();
if (fm.getBackStackEntryCount() > 0) {
Log.i("MainActivity", "popping backstack");
fm.popBackStack();
} else {
MyAlertDialog dialog=new MyAlertDialog(this);
dialog.displayDialog("Exit", "Do you wish to exit application?",0);
// super.onBackPressed(); // <-- remove this and implement closing of the activity in the Dialog logic
}
