【问题描述】：
在我的应用程序中，我创建了一个带有标题、列表视图项和取消按钮的 Alertdialog。我已经设置了项目单击列表中的每个项目。因此，如果用户单击项目，它将生成另一个带有标题、列表视图和取消的 Alertdialog。第一个 Alerdialog 的取消按钮工作正常。但是第二个 Alerdialog 的取消按钮不起作用。我不知道这背后的原因是什么。我已经实现了类似的代码。这是我的代码。
public class AlertDialogFragment extends DialogFragment{
private ListView listView1;
private ListView listView2;
private Button cancelButton1;
private Button cancelButton2;
private String[] companyName;
private String[] actionName;
private ArrayAdapter<String> adapter;
public AlertDialogFragment(){
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setCancelable(true);
setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogStyle);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.first_alertlist_contact, container, false);
//Set Title Dialog
getDialog().setTitle("Contact");
//Button,ListView1 Initialization
listView1=(ListView) rootView.findViewById(R.id.listView1);
cancelButton1=(Button) rootView.findViewById(R.id.cancel_button1);
// Defined Array values to show in ListView
companyName = getResources().getStringArray(R.array.company_name);
//Create and set Adepter TO ListView1
adapter=new ArrayAdapter<String>(getActivity(), R.layout.first_alertlist_textstyle,android.R.id.text1,companyName);
listView1.setAdapter(adapter);
cancelButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
dismiss();
}
});
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// ListView Clicked item index
int itemPosition = position;
if(itemPosition == 0)
{
dismiss();
showDialog2();
}
if(itemPosition == 1)
{
dismiss();
showDialog2();
}
if(itemPosition == 2)
{
....
}
}
});
return rootView;
}
private void showDialog2(){
final AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this.getActivity(), R.style.DialogStyle);
LayoutInflater inflater = this.getActivity().getLayoutInflater();
View dialogView = inflater.inflate(R.layout.second_alertlist_contact, null);
dialogBuilder.setView(dialogView);
listView2 = (ListView) dialogView.findViewById(R.id.listView2);
cancelButton2=(Button) dialogView.findViewById(R.id.cancel_button2);
// Defined Array values to show in ListView
actionName = getResources().getStringArray(R.array.contact_way);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(),
R.layout.first_alertlist_textstyle, android.R.id.text1, actionName);
listView2.setAdapter(adapter);
listView2.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// ListView Clicked item index
int itemPosition = position;
if(itemPosition == 0)
{
dismiss();
System.out.println("Hello");;
}
...
}
});
cancelButton2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
dialogBuilder.show();
}
}
这是我的第一个 AlertDialog 的 XML 代码
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="15dp"
android:paddingBottom="15dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:text="Contact"
android:gravity="center_horizontal"
android:textAppearance="@style/TextAppearance.AppCompat.Large"
android:layout_gravity="center"
android:textColor="#FFFFFF"
android:background="#283593"/>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listView1"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_gravity="center"
>
</ListView>
<Button
android:id="@+id/cancel_button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="@style/TextAppearance.AppCompat.Medium"
android:text="Cancel"
android:textColor="#FFFFFF"
android:background="#283593"/>
</LinearLayout>
第二个警报的 XML 代码
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:paddingRight="10dp"
android:text="What do you want to do"
android:gravity="center_horizontal"
android:textAppearance="@style/TextAppearance.AppCompat.Large"
android:layout_gravity="center"
android:textColor="#FFFFFF"
android:background="#283593"/>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listView2"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_gravity="center"
>
</ListView>
<Button
android:id="@+id/cancel_button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="@style/TextAppearance.AppCompat.Medium"
android:text="Cancel"
android:textColor="#FFFFFF"
android:background="#283593"/>
【问题讨论】：
-
尝试使用 dialogBuilder.cancel() 或 dialogBuilder.dismiss()
-
@yash786 显示无法解析方法
-
Ktina，尝试使用下面的代码，我刚刚为您制作了一个自定义对话框。尝试将 1 个对话框用于 2 个目的。
-
alertDilaouge.dismiss();你应该使用这个。
