Spinner实现选项的图标与文本并排

要实现Spinner中选项的图标与文本并排，可以使用自定义适配器来处理Spinner中每个选项的布局。以下是一个示例代码：

1. 创建一个自定义适配器类CustomAdapter继承自ArrayAdapter，并重写getView方法：

public class CustomAdapter extends ArrayAdapter<String> {
    private Context mContext;
    private List<String> mOptions;
    private List<Integer> mIcons;

    public CustomAdapter(Context context, int resource, List<String> objects, List<Integer> icons) {
        super(context, resource, objects);
        mContext = context;
        mOptions = objects;
        mIcons = icons;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View row = inflater.inflate(R.layout.spinner_row, parent, false);

        TextView textView = row.findViewById(R.id.text_view);
        ImageView imageView = row.findViewById(R.id.image_view);

        textView.setText(mOptions.get(position));
        imageView.setImageResource(mIcons.get(position));

        return row;
    }

    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        return getView(position, convertView, parent);
    }
}

2. 创建一个包含TextView和ImageView的布局文件spinner_row.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <ImageView
        android:id="@+id/image_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="8dp"/>

    <TextView
        android:id="@+id/text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</LinearLayout>

3. 在Activity中设置Spinner的适配器为自定义适配器CustomAdapter：

List<String> options = Arrays.asList("Option 1", "Option 2", "Option 3");
List<Integer> icons = Arrays.asList(R.drawable.ic_option1, R.drawable.ic_option2, R.drawable.ic_option3);

Spinner spinner = findViewById(R.id.spinner);
CustomAdapter adapter = new CustomAdapter(this, R.layout.spinner_row, options, icons);
spinner.setAdapter(adapter);

通过以上步骤，你可以实现Spinner中选项的图标与文本并排显示。
