    @Override

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        txtStart= (TextView) findViewById(R.id.edt_starttime);
        txtEnd= (TextView) findViewById(R.id.edt_endtime);
        // create RangeSeekBar as Integer range between 20 and 75
        RangeSeekBar<Integer> seekBar = new RangeSeekBar<Integer>(100, 1500, this);


        seekBar.setOnRangeSeekBarChangeListener(new OnRangeSeekBarChangeListener<Integer>() {
            @Override
            public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar,
                    Integer minValue, Integer maxValue) {
                  // handle changed range values
                 String powerranger = "User selected new range values: MIN=" + minValue + ", MAX=" + maxValue;
                 //Log.i(TAG, powerranger);
                 //textView1.setText(powerranger);
                 txtStart.setText(String.valueOf(minValue));
                 txtEnd.setText(String.valueOf(maxValue));

            }
        });

        // add RangeSeekBar to pre-defined layout
        ViewGroup layout = (ViewGroup) findViewById(R.id.layout);
        layout.addView(seekBar);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Problem i am facing ::

• During moving the thump it is not updating the textView with the value of range
• value is updated only after we remove the hand from the thumb

我快速查看了代码，看起来RangeSeekBar类有一个notifyWhileDragging属性，你必须将其设置为true才能得到你想要的东西（默认为false ）。
