how to get RatingBar value

how to read and display rating bar value

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]);
    }
};

// this works

private OnClickListene开发者_JAVA百科r 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]);
    }
};

What you do here is not right: you output the resource id of the rating bar, not its value.

Let me assume that you have earlier done something like:

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

for example in the activity's onCreate(). Then within the on click listener you provide, you can get the rating as follows:

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

Simple call

  ratingBar.getRating() ; GET RATING BAR VALUE

When you want to get the rating value when changed

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

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

}

use this to get rating

(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);

 }

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();
            }
        });

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());
}

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

//use ratings within event listner code block

float rating = rate.getRating();

import android.widget.RatingBar;
