getNumStars（）方法返回的評價 –

你好功率MOSFET，檢查我的答案。 –

以下所有答案都不適用 –

你在這裏做的是不正確的：你輸出的評級欄的資源ID，而不是它的價值。

讓我假定你已經做得比較早是這樣的：

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

例如在活動的onCreate()。然後，在您提供的點擊聆聽者內，您可以獲得如下評分：

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

簡單的通話

ratingBar.getRating() ; GET RATING BAR VALUE

如果你想獲得評級值改變時

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

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

}

使用該得到的評價

(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); 

}

RatingBar rate = (RatingBar)findViewById(R.id.R_rate); 

//use ratings within event listner code block 

float rating = rate.getRating();

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(); 
      } 
     });
