返回值页面

Intent intent =getIntent();
//这里使用bundle绷带来传输数据
Bundle bundle =new Bundle();
bundle.putString("url",mVideoPath);
intent.putExtras(bundle);
setResult(RESULT_OK,intent);
finish();

绝对路径

storage/emulated/0/DownloadFile/jg0DAFgi6G-AKqsqADDP_nSW5F4051.mp3

转换成带file：的路径

File file = new File(url);

转换成content：//的路径

Uri imageContentUri = getImageContentUri(this, file);

public static Uri getImageContentUri(Context context, java.io.File imageFile) {
    String filePath = imageFile.getAbsolutePath();
    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            new String[] { MediaStore.Images.Media._ID }, MediaStore.Images.Media.DATA + "=? ",
            new String[] { filePath }, null);
    if (cursor != null && cursor.moveToFirst()) {
        int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
        Uri baseUri = Uri.parse("content://media/external/images/media");
        return Uri.withAppendedPath(baseUri, "" + id);
    } else {
        if (imageFile.exists()) {
            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DATA, filePath);
            return context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        } else {
            return null;
        }
    }
}
