Android 搜索栏文本视图

Question

我有3个seekbar来改变背景颜色。每个搜索栏都有一个 0-255 的 textView，以 RGB 格式显示颜色代码。当我滑动其中一个搜索栏时，RGB textView 全部改变。我如何指定，只有属于搜索栏的textView，我滑动才会改变？

  private SeekBar.OnSeekBarChangeListener seekBarChangeListener
        = new SeekBar.OnSeekBarChangeListener()
{

    TextView seekBar1Progress;
    TextView seekBar2Progress;
    TextView seekBar3Progress;


    @Override
    public void onProgressChanged(SeekBar seekBar, int progress,
                                  boolean fromUser) {

        updateBackground();
        seekBar1Progress = (TextView) findViewById(R.id.viewSlider1);
        seekBar1Progress.setText(" " + progress);
        seekBar2Progress = (TextView) findViewById(R.id.viewSlider2);
        seekBar2Progress.setText(" " + progress);
        seekBar3Progress = (TextView) findViewById(R.id.viewSlider3);
        seekBar3Progress.setText(" " + progress);
    }
    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
    }
};

您正在 OnProgressChanged 方法中获取 SeekBar 对象，您可以将其 id 与您的个人 SeekBar 进行比较。试试下面的代码：

@Override
        public void onProgressChanged(SeekBar seekBar, int progress,
                                      boolean fromUser) {
            if(seekBar.getId()==R.id.seekBar1){
                seekBar1Progress = (TextView) findViewById(R.id.viewSlider1);
                seekBar1Progress.setText(" " + progress);
            }else if(seekBar.getId()==R.id.seekBar2){
                seekBar2Progress = (TextView) findViewById(R.id.viewSlider2);
                seekBar2Progress.setText(" " + progress);
            }else{
                seekBar3Progress = (TextView) findViewById(R.id.viewSlider3);
                seekBar3Progress.setText(" " + progress);
            }


        }

希望这会有所帮助！！
