I created a series of sliders for selecting values, when the activity starts all the thumbs and their corresponding dynamic text appear at the same starting point. Once you move the slider to the right the dynamic text never really stay centred to the Thumb. When the slider is all the way to the right the dynamic text falls off the screen in some cases.

Seekbar Left Edge Seekbar Middle Seekbar Right Edge

What I want to accomplish is all the dynamic text to appear on the left side like the Score Slider on the left (see first image), when sliding the the thumb anywhere between the min and the max value the dynamic text should be centred to the Thumb (see second image). When the slider is at the maximum range all the dynamic text should look like the Spares and Splits sliders (see third image).

    }
}

I have gone through several different posts, but cannot seem to find anything that might help me out. If anyone can provide some insight on this I would greatly appreciate it.

I have also tried the following code:

textViewScore.setText(Integer.toString(progress));
                        double pourcent = progress / (double) seekBarScore.getMax();
                        int offset = seekBar.getThumbOffset();
                        int seekWidth = seekBarScore.getWidth();
                        int val = (int) Math.round(pourcent * (seekWidth - 2 * offset));
                        int labelWidth = textViewScore.getWidth();
                        textViewScore.setX(offset + seekBarScore.getX() + val
                                - Math.round(pourcent * offset)
                                - Math.round(pourcent * labelWidth/2));

I got this from here: Add dynamic text over Android SeekBar thumb

Try this 

Point maxSizePoint = new Point();
getWindowManager().getDefaultDisplay().getSize(maxSizePoint);
int maxX = maxSizePoint.x;
textViewScore.setX(textViewScore.getMeasuredWidth() + (val + seekBar.getThumbOffset() / 2) > maxX ? (maxX - textViewScore.getMeasuredWidth() - 16) : val + seekBar.getThumbOffset() / 2);

UPDATE

I've tried with a single seekbar following is the code and output

public class MainActivity extends AppCompatActivity {
    int maxX;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SeekBar seekBarScore = findViewById(R.id.seekBarScore);
        final TextView textViewScore = findViewById(R.id.textViewScore);
        textViewScore.setText("Split Conversions : " + seekBarScore.getProgress());
        Point maxSizePoint = new Point();
        getWindowManager().getDefaultDisplay().getSize(maxSizePoint);
        maxX = maxSizePoint.x;
        seekBarScore.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
                    @Override
                    public void onProgressChanged(SeekBar seekBar, int progressValue, boolean fromUser) {
                        int val = (progressValue * (seekBar.getWidth() - 2 * seekBar.getThumbOffset())) / seekBar.getMax();
                        textViewScore.setText("Split Conversions : " + progressValue);
                        int textViewX = val - (textViewScore.getWidth() / 2);
                        int finalX = textViewScore.getWidth() + textViewX > maxX ? (maxX - textViewScore.getWidth() - 16) : textViewX + 16/*your margin*/;
                        textViewScore.setX(finalX < 0 ? 16/*your margin*/ : finalX);
                    }

                    @Override
                    public void onStartTrackingTouch(SeekBar seekBar) {
                    }

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

    }
}

  • With the code you provided above I am getting pretty much the same results. – Robert Vogl Jul 05 '18 at 13:49
  • I also tried messing around with the values in the code but the results were also similar to the screen shots above. – Robert Vogl Jul 05 '18 at 13:57
