Java 更改Android上的分级栏

我的应用程序中有一个分级栏，我想当我把鼠标放在上面时，分级会改变

我该怎么做？有可能吗

致以最诚挚的问候

安卓系统中没有鼠标。

安卓系统中绝对没有鼠标，但点击事件后，您可以在评级栏中进行更改

您是否已将android:isIndicator设置为false？这是我能回忆起的第一个针对android的鼠标悬停查询。android确实支持鼠标或其他指向设备，但很少使用。

 public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromTouch) {
    final int numStars = ratingBar.getNumStars();
    mRatingText.setText( 
            getString(R.string.app_name) + " " + rating + "/" + numStars);

    // Since this rating bar is updated to reflect any of the other rating
    // bars, we should update it to the current values.
    if (mIndicatorRatingBar.getNumStars() != numStars) {
        mIndicatorRatingBar.setNumStars(numStars);
        mSmallRatingBar.setNumStars(numStars);
    }
    if (mIndicatorRatingBar.getRating() != rating) {
        mIndicatorRatingBar.setRating(rating);
        mSmallRatingBar.setRating(rating);
    }
    final float ratingBarStepSize = ratingBar.getStepSize();
    if (mIndicatorRatingBar.getStepSize() != ratingBarStepSize) {
        mIndicatorRatingBar.setStepSize(ratingBarStepSize);
        mSmallRatingBar.setStepSize(ratingBarStepSize);
    }
}
