How to display some value on seekbar as default?

Use this one

android:progress="5"

Like "progress", it inherits some of it's attributes from ProgressBar. You find all the attributes at http://developer.android.com/reference/android/widget/SeekBar.html

To get Seekbar at the value of 5

In the xml layout use the max value as 10

  android:max="10"

In the java for seekbar to get at progress 5

 seekbar = (SeekBar) findViewById(R.id.seekBar1); seekbar.setProgress(5);

thats it :)

I hope this code surely helps you.
Try this...

float discrete=0;  float start=0;  float end=100;  float start_pos=0;  int start_position=0; @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     start=-10;      //you need to give starting value of SeekBar end=10;         //you need to give end value of SeekBar     start_pos=5;    //you need to give starting position value of SeekBar     start_position=(int) (((start_pos-start)/(end-start))*100);     discrete=start_pos;     SeekBar seek=(SeekBar) findViewById(R.id.seekBar1);     seek.setProgress(start_position);     seek.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {         @Override         public void onStopTrackingTouch(SeekBar seekBar) {             // TODO Auto-generated method stub             Toast.makeText(getBaseContext(), "discrete = "+String.valueOf(discrete), Toast.LENGTH_SHORT).show();         }         @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             // To convert it as discrete value             float temp=progress;             float dis=end-start;             discrete=(start+((temp/100)*dis));         }     }); }
