android - 搜索栏没有到达终点

Question

我正在开发一款使用 seekbar 的应用程序。我的 seekbar 的最大值为 6，即 android:max="6"，因为我希望间隔为 5。我的问题是 seekbar 没有到达终点我尝试了很多东西但仍然无能为力，所以任何人都可以建议我该怎么做。我的代码是

 public class MainActivity  extends Activity implements SeekBar.OnSeekBarChangeListener 
  {

    SeekBar seekBar;


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

    seekBar=(SeekBar)findViewById(R.id.seek);
  int max = 6;
seekBar.setMax(max);
seekBar.setProgress(0);

    seekBar.setOnSeekBarChangeListener(this);
}

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


}

public void onStartTrackingTouch(SeekBar seekBar) {
    // Notify that the user has started a touch gesture.


}

public void onStopTrackingTouch(SeekBar seekBar) {
    // Notify that the user has finished a touch gesture.

}

}

谢谢

public class MyActivity extends Activity implements SeekBar.OnSeekBarChangeListener {

private SeekBar sb;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
      sb = (SeekBar)findViewById(R.id.sb);
      sb.setOnSeekBarChangeListener(this);
     }


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

}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override
