Question

我希望在进度发生变化时更改android中的搜索栏颜色。在下图中，蓝色为1-2，绿色为2-3，依此类推。可能吗？到目前为止，我的代码是;

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SeekBar seekBar = (SeekBar)findViewById(R.id.seekbar);
        seekBar.setProgress(0);
        seekBar.incrementProgressBy(10);
        seekBar.setMax(200);
        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                progress = progress / 10;
                progress = progress * 10;
                    int stepSize = 25;
                    progress = (progress/stepSize)*stepSize;
                    seekBar.setProgress(progress);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });
    }
