@Override
public void onValueSelected(Entry e, int dataSetIndex, Highlight h) {
    myTextView.setText("" + e.getVal());
}

Unfortunately,i have do this in my code,but this method seems not work...also,
@Override public void onValueSelected(Entry e, int dataSetIndex, Highlight h) { float val = e.getVal(); Log.v("1...................","bar was touched:"+Float.toString(val)); }
why i cannot see any log in my studio?

Without any further information, I have no idea, I can only guess.

Have you set the listener?

chart.setOnChartValueSelectedListener(this)
