Android Listview对话框在选择一个项目后不会消失

Question

我试图创建一个列表视图对话框来显示选择列表。我的代码如下所示：

 LayoutInflater factory=LayoutInflater.from(this); 
    final View stuckLevelDialogView=factory.inflate(R.layout.report_stuck_dialog, null); 

    final ListView stuckLevelListViewForDialog=(ListView)stuckLevelDialogView.findViewById(R.id.report_stuck_dialog_listview); 
    final String[] stuckLevelList=new String[]{"1 - You can move freely","2 - You have to be aware of your movement","3 - You can move slowly","4 - There is a traffic jam","5 - There is a serious traffic jam"}; 
    ArrayAdapter<String> adapterForDialog=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stuckLevelList); 
    stuckLevelListViewForDialog.setAdapter(adapterForDialog); 

    final AlertDialog.Builder stuckLevelDialog=new AlertDialog.Builder(this); 
    stuckLevelDialog.setTitle("What stuck level is this point?"); 
    stuckLevelDialog.setView(stuckLevelDialogView); 
    stuckLevelDialog.show(); 

然而，当我选择一个选项，onItemClick被执行，但列表视图对话框不消失，我必须手动按后退按钮。我试图调试一整天的代码，但还没有解决。请帮帮我。先进的感谢！

Answer 1

我认为你需要dismiss()在对话框中你onItemClick听众如下：

stuckLevelListViewForDialog.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> p_arg0, View p_arg1, 
       int p_arg2, long p_arg3) { 
     stuckLevelDialog.dismiss(); 
     } 
    }); 

Answer 2

使用stuckLevelDialog.dismiss;在onItemClick结束时。

您可以在警报对话框中设置setSingleChoiceItems，其中的项目列表将显示带有单选按钮的列表。如果你想添加按钮，你可以一旦用户选择任何项目，你可以dismissdialog。

new AlertDialog.Builder(this) 
    .setSingleChoiceItems(array, -1, new DialogInterface.OnClickListener() { 

       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        // here you can do your functionality and can dismiss dialog as well 
        dialog.dismiss(); 

       } 
      })   
    .show();
