Android SeekBar使用 监听方法

1.SeekBar 是一个可以拖动的控件

需要实现

seekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {    @Override    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {        Log.i(TAG,"onProgressChanged=" +progress);    }    @Override    public void onStartTrackingTouch(SeekBar seekBar) {        Log.i(TAG,"onStartTrackingTouch=");    }    @Override    public void onStopTrackingTouch(SeekBar seekBar) {        Log.i(TAG,"onStopTrackingTouch=");    }});

2.

//拖动条进度改变的时候调用

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {    Log.i(TAG,"onProgressChanged=" +progress);}

//拖动条开始拖动的时候调用

    @Override    public void onStartTrackingTouch(SeekBar seekBar) {        Log.i(TAG,"onStartTrackingTouch=");    }

//拖动条停止拖动的时候调用

    @Override    public void onStopTrackingTouch(SeekBar seekBar) {        Log.i(TAG,"onStopTrackingTouch=");    }

3.例：
SeekBar seekbar= (SeekBar) findViewById(R.id.seekBar);//拿到控件实例seekbar.setMax(100);//为控件设置大小
4.当
seekbar
 拖动的时候log cat 日志
