在AlertDialog中显示列表[重复]

Question

我正在使用一个警报对话框，显示一个菜单在应用程序的开始，我想要对话框显示我的两个值，是“名称”从一个对象，这里是警报对话框的代码：

public void showDialog() {

    EntityType en = new EntityType();
    ArrayList array = ApplicationController.entities;

    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick one");
    builder.setItems(array, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // I want to write my code here
        }
    });

    builder.show();
}

EntityType是包含字符串“name”的对象，ApplicationController.Entitys包含数组

Answer 1

public void showDialog() {

    EntityType en = new EntityType();
    ArrayList array = ApplicationController.entities;

    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick one");
    ArrayList<String> displayValues=new ArrayList<>();
      for (Entity entity : array) {
         displayValues.add(entity.name);
      }

      ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_1,array);
      final AlertDialog.Builder builder = new AlertDialog.Builder(this);
      builder.setTitle("Pick one");
      builder.setSingleChoiceItems(displayValues, 0, new DialogInterface.OnClickListener() {
         @Override
         public void onClick(DialogInterface dialog, int which) {
            Entity selectedItem = array[which];
         }
      });    


    builder.show();
}
