如何获取RatingBar的值

Question

如何读取和显示评分条的值

i[0] // should be selected value

private OnClickListener onclickbutton1 = new OnClickListener() {
    public void onClick(View v) {
        int[] i = new int[]{ R.id.mRatingBar};

        statusMessage.setText("value is " + i[0]);
    }
};

// 这个有效

private OnClickListener onclickbutton1 = new OnClickListener() {
    public void onClick(View v) {
        RatingBar mBar = (RatingBar) findViewById(R.id.mRatingBar);

        float[] i = new float[]{ mBar.getRating() };

        statusMessage.setText("value is.. " + i[0]);
    }
};

getNumStars()方法返回评分。 - Nikunj Patel

你好，Power-Mosfet，请检查我的答案。 - Dipak Keshariya

Answer 1

你现在的做法是不正确的：你输出了评分条的资源id，而不是它的值。

让我假设你之前做过类似以下的事情：

RatingBar mBar = (RatingBar) findViewById(R.id.mRatingBar);
mBar.setOnClickListener(onclickbutton1);

例如在活动的onCreate()中。然后在您提供的单击监听器内，可以按以下方式获取评分：

public void onClick(View v) {
    RatingBar bar = (RatingBar) v;
    statusMessage.setText("value is " + bar.getRating());
}

Answer 2

简单调用

  ratingBar.getRating() ; GET RATING BAR VALUE

当您想在更改时获取评级值

     public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromTouch) {

     final int numStars = ratingBar.getNumStars();
     ratingBar.getRating() ;
     final float ratingBarStepSize = ratingBar.getStepSize();

}

Answer 3

rbRatingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {

                Float ratingVal = (Float) rating;
                Float ratingvalue = (Float) rbRatingBar.getRating();
                Toast.makeText(getApplicationContext(), " Ratings : " + String.valueOf(ratingVal) + "", Toast.LENGTH_SHORT).show();
                Toast.makeText(getApplicationContext(), " Ratings1 : " + ratingvalue + "", Toast.LENGTH_SHORT).show();
            }
        });

请在您的答案中添加描述 - Gregor Doroschenko

你需要什么样的描述？这里的rbRating Bar是评分栏，一切都设置好了，我甚至使用了本地变量，所以任何人都不必查找任何东西。 - Deepak Rajput

即使我展示了两种获取评分条值的方法 - Deepak Rajput

只需使用 onRatingChanged() 提供的浮点值。 - Vikash Sharma

Answer 4

RatingBar ratingBar = (RatingBar) findViewById(R.id.mRatingBar);
RatingBar.setOnClickListener(onclickbutton1);

public void onClick(View v) {
    RatingBar bar = (RatingBar) v;
    rating.setText("value is " + bar.getRating());
}

Answer 5

使用此功能获取评分。

(RatingBar)findViewById(R.id.ratingbar1)).setOnRatingBarChangeListener(this);
        ((RatingBar)findViewById(R.id.ratingbar2)).setOnRatingBarChangeListener(this);
    }

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

 }
