如何从android中的画廊获取视频缩略图和uri

Question

@ Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (data.getData()!=null) {
        videoUri = data.getData();


        if (resultCode == RESULT_OK) {
            if (requestCode == REQUEST_VIDEO) {
                Toast.makeText(this, data.getData().toString(), Toast.LENGTH_LONG).show();

            } else if (requestCode == VIDEO_RECORD_REQUEST) {
                videoUri = data.getData();
                Toast.makeText(this, data.getData().toString(), Toast.LENGTH_LONG).show();
            }
        }
    }
    else
    {
        Toast.makeText(this, "No file", Toast.LENGTH_SHORT).show();
    }

}

我已经尝试过这段代码，它工作正常，但我也想获取结果视频 URI 的缩略图。

Answer 1

在onActivityResult

String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = context.getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();

Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(picturePath, MediaStore.Video.Thumbnails.MICRO_KIND);
