setMultiChoiceItems带对话框中的图标 - Android

Question

我试图用带有图标的适配器设置AlertDialog方法，setMultiChoiceItems，但是它接受的唯一方法是setSingleChoiceItems，但它必须是多重的。用户单击按钮并显示一个对话框，其中包含他可以选择的图标。我已经搜索了有关alert.dialog，适配器的文档，我确实没有发现任何相关内容。问题是，如何创建适配器或在对话框中设置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;
}

}

我想做的事情：

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();
        }
    });
