}okay now to the problem when i call the findviewbyid for the progress bar in sendvideomessage ffmpeg onsuccess callback it returns null even though the findviewbyid for the the imageview which is in the same layout it returns the view ! so please tell me what is the problem
public void onSuccess(String message1) {
Log.w("Zipping","Success");
RelativeLayout v = (RelativeLayout) mEssageBox.findViewById(rowid.intValue()); ;
ProgressBar progressBar = (ProgressBar) v.findViewById(R.id.message_entity_Right_progressbar); // this keeps returning null!
ImageView iv = (ImageView) v.findViewById(R.id.message_entity_right_imageview); // returns the view
// progressBar.setVisibility(View.GONE);
Bitmap bitTh = ThumbnailUtils.createVideoThumbnail(ZippedVideoPath, MediaStore.Images.Thumbnails.MINI_KIND);
iv.setImageBitmap(bitTh);
progressBar.setVisibility(View.GONE);
iv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(ZippedVideoPath));
intent.setDataAndType(Uri.parse(ZippedVideoPath), "video/mp4");
startActivity(intent);
}
});
UploadVideo uv = new UploadVideo(v);
uv.execute();
}Thank you !
