Set lower limit of number of stars shown in RatingBar Android
With the RatingBar widget in android you can set the number of stars to be show, but is there a way of setting a lower limit on the number of stars that are always active. As an example ra开发者_C百科ting a film or something where you cannot submit a rating of 1?
If this is not possible in the framework strictyl speaking, you could put a default value of 1 with android:rating
set to 1, and the add a listener on the RatingBar
to go back to 1 when the user tries to go lower no?
is there a way of setting a lower limit on the number of stars that are always active.
Yes you can set the Rating using setRating()
method.
For example:
ratingBar.setRating(rat);
As an example rating a film or something where you cannot submit a rating of 1?
For this, you have to implement a condition inside the onRatingChanged() method. for example:
ratingBar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {
@Override public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromUser) {
// implement your condition here
}
});
<RatingBar android:id="@+id/ratingbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="1.0"
android:rating="1"/>
By setting rating =1 it is shows rating 1.
As mentioned by @sephy supporting his answer. I am adding a sample code which I have used in my app.
mRatingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
if(selectedRating<=0) {
mRatingBar.setRating(1);
}
}
});
