I use this code to show a decimal value by a rating bar. but it round the value and show first bigger int
ratingBar.setNumStars(5);
ratingBar.setMax(5);
ratingBar.setStepSize(0.5f);
ratingBar.setRating(Float.parseFloat("2.5"));
in XML file
<RatingBar
android:id="@+id/ratingBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:max="5"
android:layoutDirection="ltr"
android:numStars="5"
android:stepSize="0.5" />
Layout:
<RatingBar android:id="@+id/ratingbar" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="0.5"/>
Activity:
private RatingBar ratingBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ratingBar = (RatingBar)findViewById(R.id.ratingBar);
assert ratingBar != null;
dosomething();
ratingBar.setRating(0.0f);
}
private void dosomething() {
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
ratingBar.setRating(2.5f);
}
}, 2000);
}
I test your code in sdk 23
and have same problem . I can't figure out way this append but you can temporarily solve it by set rounded value before set the float
.like this :
ratingBar.setRating(Math.round( 2.5f));
ratingBar.setRating( 2.5f);
also don't set setMax
just setStepSize
. let me know if it worked.
