[英]How to not close AlertDialog android
Hi my problem is when I select an item my AlertDialog
dismiss 嗨,我的问题是当我选择一个项目时, AlertDialog
关闭了
alertDialog = new AlertDialog.Builder(getActivity());
alertDialog
.setSingleChoiceItems(ageArr, 1, btnSelectItem)
.setPositiveButton(R.string.dialog_ok, btnPositiveAgeDialog)
.setNegativeButton(R.string.dialog_cancel, null)
.show();
what my dialog click positive looks is. 我的对话框点击正面看起来是什么。
private DialogInterface.OnClickListener btnSelectItem = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
selectedIndexAge = which;
}
};
I tried setting the listener to null and it does not close but still I needed it because I wanted to know which item is selected 我尝试将侦听器设置为null,但它不会关闭,但是我仍然需要它,因为我想知道选择了哪个项目
Just put it 放一下
itemView.setOnClickListener(null);
or 要么
You can use the implementation of hasOnClickListeners() for knowing the status of listener taken from android.view.View class for 您可以使用hasOnClickListeners()的实现来了解从android.view.View类获取的侦听器的状态
public boolean hasOnClickListeners() {
ListenerInfo li = mListenerInfo;
return (li == null && li.mOnClickListener == null);
}
Use the following link for further modifications 使用以下链接进行进一步修改
Set listener instance in fragment on application restore 在应用程序还原时在片段中设置侦听器实例
try this 尝试这个
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
Boolean wantToCloseDialog = false;
//Do stuff, possibly set wantToCloseDialog to true then...
if(wantToCloseDialog)
dialog.dismiss();
//else dialog stays open. Make sure you have an obvious way to close the dialog especially if you set cancellable to false.
}
});
Something else must be closing your AlertDialog
. 某些其他原因可能正在关闭AlertDialog
。 Below is a program that I believe duplicates the minimum requirements you have posted, and selecting one of the items does not close the dialog. 我相信以下程序可以重复您发布的最低要求,并且选择其中一项不会关闭对话框。
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] values = new String[]{ "one", "two", "three", "four" };
DialogInterface.OnClickListener choiceListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "selected index: " + which, Toast.LENGTH_SHORT).show();
}
};
DialogInterface.OnClickListener positiveListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "positive button", Toast.LENGTH_SHORT).show();
}
};
new AlertDialog.Builder(this)
.setSingleChoiceItems(values, 1, choiceListener)
.setPositiveButton("ok", positiveListener)
.setNegativeButton("cancel", null)
.show();
}
}
