如何在Android中使用ContentResolver查询自定义文件夹中的图片/视频？

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

public void queryMediaFiles(ContentResolver contentResolver, String folderPath) {
    // 查询图片
    Uri imagesUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
    String[] projection = {MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA};
    String selection = MediaStore.Images.Media.DATA + " like ?";
    String[] selectionArgs = new String[]{"%" + folderPath + "%"};
    
    Cursor imageCursor = contentResolver.query(imagesUri, projection, selection, selectionArgs, null);
    if (imageCursor != null) {
        while (imageCursor.moveToNext()) {
            String imagePath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
            // 处理图片路径
        }
        imageCursor.close();
    }

    // 查询视频
    Uri videosUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
    Cursor videoCursor = contentResolver.query(videosUri, projection, selection, selectionArgs, null);
    if (videoCursor != null) {
        while (videoCursor.moveToNext()) {
            String videoPath = videoCursor.getString(videoCursor.getColumnIndex(MediaStore.Video.Media.DATA));
            // 处理视频路径
        }
        videoCursor.close();
    }
}
