import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    SeekBar seekBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        seekBar=(SeekBar)findViewById(R.id.seekBar);

            @Override
            public void onProgressChanged(SeekBar seekBar, int progress,
                                          boolean fromUser) {
                Toast.makeText(getApplicationContext(),"seekbar progress: "+progress, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {
                Toast.makeText(getApplicationContext(),"seekbar touch started!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
