如何使用URI (Android)创建目录？

import android.content.ContentResolver;
import android.content.ContentValues;
import android.net.Uri;
import android.os.Environment;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 获取外部存储目录的URI
        Uri parentUri = Uri.parse(Environment.getExternalStorageDirectory().toString());

        // 要创建的目录名称
        String directoryName = "myDirectory";

        // 构建新的URI
        Uri newUri = Uri.withAppendedPath(parentUri, directoryName);

        // 创建目录
        ContentResolver contentResolver = getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, directoryName);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "vnd.android.cursor.dir/none");
        contentResolver.insert(newUri, contentValues);
    }
}
