如何确定哪个android小部件正在调用我的函数？

Question

I have several SeekBar s in an Android app that do practically the same thing (set bass, treble, volume). To save typing out new local classes for OnSeekBarChangeListener per SeekBar , I tried to make a single class that in its onStopTrackingTouch would determine which widget was calling it, and do the proper action.

public class mySeekBar implements SeekBar.OnSeekBarChangeListener {
    int progressChanged = 0;

    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
        progressChanged = progress;
    }

    public void onStartTrackingTouch(SeekBar seekBar) {}

    public void onStopTrackingTouch(SeekBar seekBar) {
          // i want a case statement here switched on the widget ID/name, so 
          // i can set the appropriate string s (bass, treble, volume)
        String s = "set_treble " + progressChanged;
        client.sendMessage(s);
    }

}

How do I figure out which widget is calling the onStopTrackingTouch ? Or is there a cleaner or better way of doing this?

Answer 1

100 % you can determine like this;

public void onStopTrackingTouch(SeekBar seekBar) {
          // i want a case statement here switched on the widget ID/name, so 
          // i can set the appropriate string s (bass, treble, volume)
        String s = "set_treble " + progressChanged;
        client.sendMessage(s);

       switch (seekBar.getId()) {
                case R.id.seekVolume:

                    break;
                case R.id.bass:
                    break;
                case R.id.trouble:
                    break;
                default:
                    break;
                }
    }
