android - 我可以在列表单击时关闭警报对话框吗？

Question

我有一个警报对话框，上面有一个列表，我想关闭 onlistclick 是否可以？

    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    final String[] Categories = SQLiteHelper.getAllCategories();//this is where i get the array for my list
    ListView myList = new ListView(this);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.alert_dialog_list_view, Categories);
    myList.setAdapter(adapter);
    myList.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {
                     //doing something in here and then close
         }
    });
    builder.setTitle("Please Choose");
    builder.setInverseBackgroundForced(true);
    builder.setView(myList);
    final Dialog dialog = builder.create();
    dialog.show();
    }

警报对话框运行完美，我只是不想在其中放置任何按钮。

如果您在 Dialog 之后定义 onItemClickListener ，您只需调用 dialog.dismiss(); onItemClick() 方法。
