android Seekbar show progress value along the seekbar

I have a listview with seekbar, each seekbar represents 100% of a value of product. By moving the seekbar the % value can be changed, I want to show the change in value along the seekbar while the user is dragging the seekbar. I do not wish to add another text box where the value is updated.

I am more looking at options to show a small view on top of the seekbar pointer, which appears onStartTracking and disappears onStopTracking event.

Is there a way to achieve this?

Here is a one simple way,

• Add a textView in your XML
• Change it's position with the movement of the seekBar
• That will position it using setX()
• If you want you can give setY() for its Y position as well
• If you want to hide write some logic and make textView Visibility GONE when you need.

example:

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
                @Override
                public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

                    int val = (progress * (seekBar.getWidth() - 2 * seekBar.getThumbOffset())) / seekBar.getMax();
                    textView.setText("" + progress);
                    textView.setX(seekBar.getX() + val + seekBar.getThumbOffset() / 2);
                    //textView.setY(100); just added a value set this properly using screen with height aspect ratio , if you do not set it by default it will be there below seek bar 

                }

or you can use Paint with your custom SeekBar class without any TextView

Create a class

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.widget.SeekBar;


public class MySeekBar extends SeekBar {
    public MySeekBar (Context context) {
        super(context);
    }

    public MySeekBar (Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public MySeekBar (Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onDraw(Canvas c) {
        super.onDraw(c);
        int thumb_x = (int) (( (double)this.getProgress()/this.getMax() ) * (double)this.getWidth());
        float middle = (float) (this.getHeight());

        Paint paint = new Paint();
        paint.setColor(Color.BLACK);
        paint.setTextSize(20);
        c.drawText(""+this.getProgress(), thumb_x, middle, paint);
    }
}

Set/create your SeekBar in your XML

  <yourPackageName.MySeekBar
            android:id="@+id/my_seek_bar"
            android:layout_width="300dp"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_marginTop="26dp"
            android:max="10"/>

Now from your Activity

seekBar = (MySeekBar) findViewById(R.id.my_seek_bar);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
    }
});
