Android SeekBar setOnSeekBarChangeListener

I hope this will help you:

final TextView t1=new TextView(this); t1.setText("Hello Android");        final SeekBar sk=(SeekBar) findViewById(R.id.seekBar1);     sk.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {           @Override           public void onStopTrackingTouch(SeekBar seekBar) {              // TODO Auto-generated method stub          }           @Override           public void onStartTrackingTouch(SeekBar seekBar) {             // TODO Auto-generated method stub          }           @Override           public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {             // TODO Auto-generated method stub              t1.setTextSize(progress);        Toast.makeText(getApplicationContext(), String.valueOf(progress),Toast.LENGTH_LONG).show();    }       });             

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).

Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.

In your onCreate:

 yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar); yourSeekBar.setOnSeekBarChangeListener(new yourListener());

Your listener:

private class yourListener implements SeekBar.OnSeekBarChangeListener {        public void onProgressChanged(SeekBar seekBar, int progress,                boolean fromUser) {                            // Log the progress            Log.d("DEBUG", "Progress is: "+progress);                            //set textView's text            yourTextView.setText(""+progress);        }        public void onStartTrackingTouch(SeekBar seekBar) {}        public void onStopTrackingTouch(SeekBar seekBar) {}    }

Please share some code and the Log results for furter help.

onProgressChanged is called every time you move the cursor.

@Overridepublic void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {    textView.setText(String.valueOf(new Integer(progress)));        }

so textView should show the progress and alter always if the seekbar is being moved.
