Question

Wie man den Wert der Bewertungsleiste liest und anzeigt

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]);
    }
};

// das funktioniert

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]);

};

Answer 1

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

//use ratings within event listner code block

float rating = rate.getRating();

Answer 2

import android.widget.RatingBar;

public class PageAboutFragment extends Fragment implements RatingBar.OnRatingBarChangeListener  {

rbSearch.setOnRatingBarChangeListener(this);

public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
        tvRatingContent.setText(rating+"/5 Stars");
}

Answer 3

var ratingBar = findViewById<RatingBar>(R.id.ratingBarid);
var text1 = findViewById<TextView>(R.id.textViewid)

// rating bar click to show the text view

ratingBar.setOnRatingBarChangeListener(object: RatingBar.OnRatingBarChangeListener{

    override fun onRatingChanged(ratingBar: RatingBar?, rating: Float, fromUser: Boolean) {
       // TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
        text1.text = "Rating bar result $rating"
    }
})

Answer 4

    var ratingBar = findViewById<RatingBar>(R.id.ratingBarid);
    var btn= findViewById<Button>(R.id.buttonid);
    var text1 = findViewById<TextView>(R.id.textViewid)

    /*

     3rd rules of

    if (ratingBar!=null){

        btn.setOnClickListener {

            val msg = ratingBar.rating.toString();
            text1.setText("The result of $msg")
        }
    }

   // rating bar click to show the text view

   // ratingBar.setOnRatingBarChangeListener(this)

              // 1st rules of Rating Bar..
  ratingBar.setOnRatingBarChangeListener(object: RatingBar.OnRatingBarChangeListener{

      override fun onRatingChanged(ratingBar: RatingBar?, rating: Float, fromUser: Boolean) {
         // TODO("not implemented") //To change body of created functions use File | Settings | File Templates.

          text1.text = "Rating bar result $rating"
      }
  })

}

            // 2nd rules of Rating bar ....
override fun onRatingChanged(ratingBar: RatingBar?, rating: Float, fromUser: Boolean) {
    //TODO("not implemented") //To change body of created functions use File | Settings | File Templates.

    var text1 = findViewById<TextView>(R.id.textViewid)
    text1.text = "Rating Bar Result : $rating"
