How can I decrease the size of Ratingbar?

Question

In my activity I have some Rating bars. But the size of this bar is so big! How can I make it smaller?

Edit

Thanks to Gabriel Negut, I did it with the following style:

<RatingBar
style = "?android:attr/ratingBarStyleSmall"
android:numStars = "5"
android:rating   = "4" />

Now, the size is reduced but number of stars and rating do not take effect!!! Why? I have 7 stars that 6 of them is selected.

Do you mean a Seekbar? Setting height and width works fine for me. Can you post your code snippet here? – Tshombe

I would recommend removing the "edit" and instead making it the accepted answer. That or @GabrielNegut can edit his answer to include that kind of solution. Including the solution in the question kind of takes away from the Q&A experience. – Lipo

style="?android:attr/ratingBarStyleSmall" works for me. – Dehydrate

Answer 1

The original link I posted is now broken (there's a good reason why posting links only is not the best way to go). You have to style the RatingBar with either ratingBarStyleSmall or a custom style inheriting from Widget.Material.RatingBar.Small (assuming you're using Material Design in your app).

Option 1:

<RatingBar
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleSmall"
    ... />

Option 2:

// styles.xml
<style name="customRatingBar"   
    parent="android:style/Widget.Material.RatingBar.Small">
    ... // Additional customizations
</style>

// layout.xml
<RatingBar
    android:id="@+id/ratingBar"
    style="@style/customRatingBar"
    ... />

Prefab

or using this style style="?android:attr/ratingBarStyleSmall" will reduce the size. – Bismuthous

But there is a useless extra padding on the right! How to remove that?! – Medullated

Note: make width="wrap_content" to get rid of extra stars – Detestation

Answer 2

This was my solution after a lot of struggling to reduce the rating bar in small size without even ugly padding

 <RatingBar
        android:id="@+id/listitemrating"
        style="@android:attr/ratingBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleX=".5"
        android:scaleY=".5"
        android:transformPivotX="0dp"
        android:transformPivotY="0dp"
        android:isIndicator="true"
        android:max="5" />

Scale bothers alignment of sibling views and imbalances margins and spacing. – Margaret

Answer 3

If you want to show the rating bar in small size, then just copy and paste this code in your project.

  <RatingBar
    android:id="@+id/MyRating"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/getRating"
    android:isIndicator="true"
    android:numStars="5"
    android:stepSize="0.1" />

Answer 4

The below snippet worked for me to resize the ratingBar

<RatingBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleIndicator"
    android:scaleX=".5"
    android:rating="3.5"
    android:scaleY=".5"
    android:transformPivotX="0dp"
    android:transformPivotY="0dp"
    android:max="5"/>

how to change the ratting bar color for this rating bar half fill, full fill, and empty color ? – Rewire

rating parameter is used to fill the rating bar right? I used android:rating="3.5" so 3.5 stars are filled. you can set up to 5 because max = 5 is set in the xml. If you want to change the colors of the rating bar, you have to create a style in style.xml see this link : https://mcmap.net/q/144432/-android-change-color-of-ratingbar-to-golden-duplicate – Agitate

@NaveedAhmad It doesn't do any related thing to padding! Or at least, I couldn't find it. github.com/aosp-mirror/platform_frameworks_base/blob/master/… -> progressDrawable, indeterminateDrawable, minHeight, maxHeight. – Medullated

Answer 5

You can set it in the XML code for the RatingBar, use scaleX and scaleY to adjust accordingly. "1.0" would be the normal size, and anything in the ".0" will reduce it, also anything greater than "1.0" will increase it.

<RatingBar
  android:id="@+id/ratingBar1"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:scaleX="0.5"
  android:scaleY="0.5" />

Selfrevealing

the problem with this is that the ratingbar still takes up the same width and height as before even though the icons are smaller. This causes alignment issues since there is a bunch of left and right padding next to the first and last icons. For example, if you want your icons like this "XXXXX", after the scaling it will look like this "-----XXXXX-----" where the "-" is empty space and "X" is an icon. So your rating bar will seem like it got pushed to the right because of the empty space – Pampas

Im guessing you're using relative layout. Its a pain but you can tweak it to go into the right position by using android:layout_marginRight and the likes to get it the way you want. – Selfrevealing

to get scale without creating a padding on the left add android:transformPivotX="0dp" – Vallo

Working Example

             <RatingBar
                style="@style/RatingBar"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:numStars="5"
                android:rating="3.5"
                android:stepSize="0.5" />

and add this in your styles xml file

<style name="RatingBar"   
parent="android:style/Widget.Material.RatingBar.Small">
<item name="colorControlNormal">@color/primary_light</item>
<item name="colorControlActivated">@color/primary_dark</item>
</style>

This way you dont need to customise ratingBar.

Answer 7

Check my answer here. Best way to achieve it.

 <style name="MyRatingBar" parent="@android:style/Widget.RatingBar">
   <item name="android:minHeight">15dp</item>
   <item name="android:maxHeight">15dp</item>
   <item name="colorControlNormal">@color/white</item>
   <item name="colorControlActivated">@color/home_add</item>
</style>

and use like

<RatingBar
    style="?android:attr/ratingBarStyleIndicator"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:isIndicator="false"
      android:max="5"

Answer 12

In RatingBar give attribute:

Answer 13

Using Widget.AppCompat.RatingBar, you have 2 styles to use; Indicator and Small for large and small sizes respectively. See example below.

<RatingBar
    android:id="@+id/rating_star_value"
    style="@style/Widget.AppCompat.RatingBar.Small"
    ... />

Answer 14

If you are using Rating bar in Linearlayout with weightSum. Please make sure that you should not assign the layout_weight for rating bar. Instead, that place rating bar inside relative layout and give weight to the relative layout. Make rating bar width wrap content.

<RelativeLayout
    android:layout_width="0dp"
    android:layout_weight="30"
    android:layout_gravity="center"
    android:layout_height="wrap_content">
        <RatingBar
            android:id="@+id/userRating"
            style="@style/Widget.AppCompat.RatingBar.Small"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:stepSize="1" />
</RelativeLayout>

Just use style="@style/Widget.AppCompat.RatingBar.Small" it'll work for Sure!

after using this rating bar color is not changing. How to change it? – Chamberlin

Answer 16

If you only need the default style, make sure you have the following width/height, otherwise the numStars could get messed up:

android:layout_width="wrap_content"
android:layout_height="wrap_content"

Cockeyed

using this style style="?android:attr/ratingBarStyleSmall" will reduce the size – Bismuthous

Answer 17

For those who created rating bar programmatically and want set small rating bar instead of default big rating bar

    private LinearLayout generateRatingView(float value){
        LinearLayout linearLayoutRating=new LinearLayout(getContext());
        linearLayoutRating.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
        linearLayoutRating.setGravity(Gravity.CENTER);
        RatingBar ratingBar = new RatingBar(getContext(),null, android.R.attr.ratingBarStyleSmall);
        ratingBar.setEnabled(false);
        ratingBar.setStepSize(Float.parseFloat("0.5"));//for enabling half star
        ratingBar.setNumStars(5);
        ratingBar.setRating(value);
        linearLayoutRating.addView(ratingBar);
        return linearLayoutRating;
    }
