I have an asynctask that reads data from a device and then I want to show this data in a TextView. I have a ScrollView in my application, and have a TextView inside it, textview is manually scrolling but I need to update the position of the last line on update progress, here is my Asynctask code
private class ReadDataTask extends AsyncTask<Void, String, String>{
/* (non-Javadoc)
* @see android.os.AsyncTask#onProgressUpdate(Progress[])
*/
@Override
protected void onProgressUpdate(String... values) {
String frm=values[0];
Log.d("bluetoothdata", frm);
if(logtextview.getText().length()>(1024*1024)){
logtextview.setText(frm);
}else{
logtextview.append(frm);
}
// Toast.makeText(SetBluetoothActivity.this, "frame updated", Toast.LENGTH_SHORT).show();
}
@Override
protected String doInBackground(Void... params) {
while(connected){
String frame=readFrame();
publishProgress(frame);
}
return null;
}
}
What I need is to position my textview as its last line will always appear. Any help will be appreciated
