Problem: How to place rating bar and have rating value in android app?
Solution:
RatingBarDemoActivity.java
package com.technotalkative.ratingbar;
import android.app.Activity;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.Toast;
public class RatingBarDemoActivity extends Activity {
/** Called when the activity is first created. */
RatingBar ratingBar;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ratingBar = (RatingBar) findViewById(R.id.ratingBar1);
ratingBar.setOnRatingBarChangeListener(new myListener());
}
class myListener implements RatingBar.OnRatingBarChangeListener
{
@Override
public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromUser) {
// TODO Auto-generated method stub
Toast.makeText(RatingBarDemoActivity.this, "Rating => "+rating, Toast.LENGTH_SHORT).show();
}
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center">
<RatingBar
android:id="@+id/ratingBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:rating="2"
android:stepSize="1">
</RatingBar>
<!-- `rating` is used to set pre-defined rating value -->
<!-- `stepSize=='1' defines user can't give floating point rating -->
</linearLayout>
