如何从相对路径中的MediaStore中读取文件？

import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.provider.MediaStore;

public class MediaStoreUtils {
    public static void readFromMediaStore(Context context, String relativePath) {
        ContentResolver contentResolver = context.getContentResolver();

        // 查询的列名
        String[] projection = {MediaStore.Images.Media.DATA, MediaStore.Images.Media.DISPLAY_NAME};

        // 构建查询的URI
        Uri queryUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI.buildUpon()
                .appendPath(MediaStore.Images.Media.RELATIVE_PATH)
                .appendPath(relativePath)
                .build();

        // 查询MediaStore中的文件
        Cursor cursor = contentResolver.query(queryUri, projection, null, null, null);

        if (cursor != null && cursor.moveToFirst()) {
            do {
                // 获取文件路径和文件名
                String filePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
                String fileName = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME));

                // 根据文件路径进行文件读取操作
                // ...

            } while (cursor.moveToNext());
            cursor.close();
        }
    }
}
