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
