Question

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 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

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());
}
