Question

使用我自定义的customDialog来显示list.my要求就是在我的应用程序中有Edittext.i需要在editext中使用Textwatcher显示此dialog.am，而用户输入一个数字，如果用户输入凌晨1点通过它到那个对话框类并完成了一些函数来制作像10,100,1000,10000这样的列表。

现在，一旦用户从此列表中选择任何数字，我想将其设置为Editext。我可以这样做吗？我这样做了一整天？

public static void amount_dialog(final Activity activity,String str)
{
     amount=str;

     sequence_number();//from this method am generating list and setting it into my Arraylist

     dialog=new  Dialog(activity,R.style.CustomDialogTheme);    

     dialog.setContentView(R.layout.customdialog);

     ListView listView=(ListView) dialog.findViewById(R.id.listView12);              
     adapter=new ArrayAdapter<String>(activity,R.layout.list2,R.id.list_text1, strings);
     listView.setAdapter(adapter);  
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            selected_amount=adapter.getItem(arg2);

            dialog.dismiss();


        }
    });


     dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;

     dialog.show();
     dialog.setCanceledOnTouchOutside(true);


}

只需将EditText对象传递给此方法，在OnitemClickListener中，您可以使用Arraylist中的值将文本设置为EditText。

public static void amount_dialog(final Activity activity,String str,EditText edittextObject)
{
     amount=str;

     sequence_number();//from this method am generating list and setting it into my Arraylist

     dialog=new  Dialog(activity,R.style.CustomDialogTheme);    

     dialog.setContentView(R.layout.customdialog);

     ListView listView=(ListView) dialog.findViewById(R.id.listView12);              
     adapter=new ArrayAdapter<String>(activity,R.layout.list2,R.id.list_text1, strings);
     listView.setAdapter(adapter);  
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            selected_amount=adapter.getItem(arg2);
             edittextObject.setText("get the value from arraylist here");
            dialog.dismiss();


        }
    });


     dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;

     dialog.show();
     dialog.setCanceledOnTouchOutside(true);


}

我假设您作为参数传递的活动是包含EditText的活动。所以你可以这样做：

EditText editText = (EditText)activity.findViewById(theIDofYourTextEdit);
editText.setText(selectedAmount);

在你的onItemClick方法中。

我希望这会有所帮助

从Dialog内容将SetText设置为EditTextBox？
