对话框中带有图标的 setMultiChoiceItems - Android

Question

我正在尝试将带有图标的适配器设置为 AlertDialog 方法 setMultiChoiceItems，但它接受的唯一方法是用于 setSingleChoiceItems，但它必须是多选的。用户单击一个按钮并显示一个带有他可以选择的图标的对话框。我已经在有关 alert.dialog、适配器的文档中进行了搜索，但没有发现任何相关内容。问题是，如何创建适配器或具有要在对话框中设置的字符串和图像图标的东西。

我的代码：

final String [] items = new String[] {"Music", "Sport"};
    final Integer[] icons = new Integer[] {R.drawable.iconmusictest, R.drawable.iconsporttest};
    ListAdapter adapter = new ArrayAdapterWithIcon(Register30.this, items, icons);



    AlertDialog.Builder builder = new AlertDialog.Builder(Register30.this);
    builder.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which)
        {
        }
    })
    .setTitle("Select your likes")
    .setSingleChoiceItems(adapter, -1, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    final AlertDialog popUpLikes = builder.create();

我的类返回一个自定义适配器：

public class ArrayAdapterWithIcon extends ArrayAdapter<String> {

private List<Integer> images;

public ArrayAdapterWithIcon(Context context, String[] items, Integer[] images) {
    super(context, android.R.layout.select_dialog_item, items);
    this.images = Arrays.asList(images);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = super.getView(position, convertView, parent);
    TextView textView = (TextView) view.findViewById(android.R.id.text1);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        textView.setCompoundDrawablesRelativeWithIntrinsicBounds(images.get(position), 0, 0, 0);
    } else {
        textView.setCompoundDrawablesWithIntrinsicBounds(images.get(position), 0, 0, 0);
    }
    textView.setCompoundDrawablePadding(
            (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 12, getContext().getResources().getDisplayMetrics()));
    return view;
}

}

我正在尝试做的事情：

Answer 1

  boolean[] checkedItems = new boolean[items.length];

  for (int i = 0; i < items.length; i++) {
  if (selectedItems.contains(i)) {
    checkedItems[i] = true;
   } else {
    checkedItems[i] = false;
   }
}

  AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMultiChoiceItems(items, checkedItems, new 
  DialogInterface.OnMultiChoiceClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int indexSelected, 
  boolean isChecked) {
            if (isChecked) {
                selectedItems.add(indexSelected);
            }
            else if (selectedItems.contains(indexSelected)) {
                selectedItems.remove(Integer.valueOf(indexSelected));
            }
        }
    }).setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
            // TODO
        }
    }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {

            filterDialog.dismiss();
        }
    });
