I am using the Android progressbar in one of my widgets:
<ProgressBar
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="?android:attr/progressBarStyleHorizontal"
android:id="#+id/progressbar_Horizontal"
android:max="100"/>
In Android 2.x it looks well, like in the following picture. I have written the % on top of the bar itself.
But if I change in the Android Manifest
android:targetSdkVersion
to "15" the progressbar looks totaly different. It is now a thin blue line instead of a bar. The problem is that I have written above the progress bar some text, in particuallary % of the progress.
Thus as the bar is so thin this looks odd.
I cannot figure out how to increase the height of the bar again to e.g. 50dp. If I try android:layout_height="50dp" it stays still same thin.
First, you need to define the style of your progress bar in values->styles.xml of your project. something like:
<style name="tallerBarStyle" parent="#android:style/Widget.SeekBar">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">#android:drawable/progress_horizontal</item>
<item name="android:indeterminateDrawable">#android:drawable/progress_horizontal</item>
<item name="android:minHeight">8dip</item>
<item name="android:maxHeight">20dip</item>
</style>
Edit the maxHeight to your desired height.
Then in your ProgressBar add:
style="#style/tallerBarStyle"
You need to replace
style=”?android:attr/progressBarStyleHorizontal”
to
style="#android:style/Widget.ProgressBar.Horizontal"
and layout_height will work
android:layout_height="50dp"

I use two RatingBars in my xml layout:
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="0.25"
android:rating="4.25"/>
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="0.25"
android:rating="4.5"/>
Even though I set ratings to 4.25 and 4.5, both RatingBars display wrong number of stars filled. On an Android 6 device it looks like this:
On an android 4.3 device, it looks like this:
But on xml design view, I can see 4.25 and 4.5 are set. Can anyone tell me why? I do not do anything with the rating bars in my code).
Thanks.
In my opinion the problem is related to android:progressTint ,android:progressBackgroundTint & android:secondaryProgressTint.
Try to add following lines to your rating bar:
android:progressTint="Color1"
android:progressBackgroundTint="Color2"
android:secondaryProgressTint="Color3"
also try to add style to your rating bar as following:
<style name="RatingBar" parent="Theme.AppCompat"">
<item name="colorControlNormal">#color/yourColor1</item>
<item name="colorControlActivated">#color/yourColor2</item></style>
and finally add a the following line in your rating bar
style="#style/RatingBar"
It will work for you.
I have included a rating bar in android, and now I need to place a text view to immediate right if the rating bar.But I failed to do the same since, there is a lot of unwanted space (rectangular blue box) around the rating bar, which prevents me from placing the textview to its immediate right side. Is there any way to reduce this space around the rating bar , so that both the textview and the rating bar comes in same line and textview is placed next to the rating bar without a gap.Please help me with a good support! Thanks in advance! Here is my xml code for it.
<RatingBar
android:id="#+id/overall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="70dp"
android:numStars="5"
android:rating="0.0"
android:scaleX="0.4"
android:scaleY="0.4"
android:stepSize="0.01" />
You can use android default styles, Like:
style="#android:style/Widget.Holo.Light.RatingBar.Small"
in you xml layout. I am using above and have no space around it.
You can check variants here
I tried to use different suggestion but i was unsuccessful with the Android Rating bar removal of extra padding. All i did downloaded ic icons from https://material.io/icons/ and use star and star bordered icon and programmed them with switch cases.
While using the base style for the RatingBar, set the minHeight to 0dp. The base minHeight in the style itself was preventing the view from scaling down. Setting it to 0 should work as you expect a normal view (we set ours to wrap_content).
Tried to use the base (#android:style/Widget.RatingBar) and small (#android:style/Widget.DeviceDefault.RatingBar.Small and #android:style/Widget.Holo.Light.RatingBar.Small) but both fixed/limited the size of the the RatingBar regardless of what icon is used. Looking at their codes, it was no surprise.
<style name="Widget.RatingBar">
<item name="indeterminateOnly">false</item>
<item name="progressDrawable">#drawable/ratingbar_full</item>
<item name="indeterminateDrawable">#drawable/ratingbar_full</item>
<item name="minHeight">57dip</item>
<item name="maxHeight">57dip</item>
<item name="thumb">#null</item>
<item name="mirrorForRtl">true</item>
</style>
<style name="Widget.Material.RatingBar.Small" parent="Widget.RatingBar.Small">
<item name="progressDrawable">#drawable/ratingbar_small_material</item>
<item name="indeterminateDrawable">#drawable/ratingbar_small_material</item>
<item name="minHeight">16dp</item>
<item name="maxHeight">16dp</item>
</style>
<style name="Widget.Holo.Light.RatingBar.Small" parent="Widget.RatingBar.Small">
<item name="progressDrawable">#drawable/ratingbar_small_holo_light</item>
<item name="indeterminateDrawable">#drawable/ratingbar_small_holo_light</item>
<item name="minHeight">16dip</item>
<item name="maxHeight">16dip</item>
</style>
Setting the scales didn't work right either.
I am currently using an external library in my Android project imported via gradle.
This library show a notification bar with a ProgressBar circle.
This is the code I found in it's sources :
<ProgressBar
android:id="#+id/progress_bar"
android:layout_height="match_parent"
android:layout_marginBottom="4dp"
android:layout_marginTop="4dp"
style="#style/SuperActivityToast_Progress_ProgressBar"/>
The style associated is this one :
<style name="SuperActivityToast_Progress_ProgressBar" parent="android:Widget.Holo.ProgressBar">
<item name="android:layout_width">32dp</item>
<item name="android:layout_marginLeft">8dp</item>
</style>
If I understand correclty, the color of the circle shown is derived from the default one ( green on my phone ).
I need to change it!
Now, I can't modify the source code, and the library itself doesn't offer me the possibility to set the style programmatically.
There is a way to change the default style at app level or better override this specific style?
Thanks

If you are using the AppCompat theme, it uses the accentColor to tint the circle.
If you want to tint it to a different color than the Theme, then you should consider using ThemeOverylay. E.g. If you want to make the circle tint red you could do the following:
in your styles.xml
<style name="RedAccent" parent="ThemeOverlay.AppCompat.Light">
<item name="colorAccent">#F00</item>
</style>
in your ProgressBar, set the theme to be RedAccent.
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="32dp"
android:layout_height="32dp"
android:theme="#style/RedAccent"/>
And your circle will now be in red color!
After several attempts I found a solution :
ProgressBar progBar = (ProgressBar) context.getActivity().findViewById(R.id.progress_bar);
if (progBar != null) {
progBar.setVisibility(View.VISIBLE);
progBar.setIndeterminate(true);
progBar.getIndeterminateDrawable().setColorFilter(0xFFFFFFFF, android.graphics.PorterDuff.Mode.MULTIPLY);
}
Simply, i'll get a reference of the progress bar object created by the library and i change it's attributes. ( in my activity i must do that in a "OnStart" method otherwise it is null )
The most important part is the "setColorFilter" that do the magic.
For future references, this change has worked for me is:
Changing the colorControlActivated within AppTheme in your values/styles.xml file:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Main theme colors -->
....
<!-- Color for circle in progress bar -->
<item name="colorControlActivated">#DC0808</item>
</style>
With this approach, you do not need to perform any action on your <ProgressBar/> tag within your xml file.
Just add color in ProgressBar like below :
<ProgressBar
android:id="#+id/progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:visibility="gone"
android:indeterminateTint="#color/colorPrimary" // add color here
android:layout_centerVertical="true"/>
I'm having a little problem when using a custom rating bar style. I've read other topics on this, but the proposed solutions/answers are not solving the problem.
Android seems to be stretching part of the star image, creating this strange effect:
This strange effect is even visible in the graphical layout preview tool in eclipse:
The star "sprites" are: and
This is the custom style:
<style name="ratingBar" parent="#android:style/Widget.RatingBar">
<item name="android:progressDrawable">#drawable/rating_bar</item>
<item name="android:minHeight">#dimen/ratingBarHeight</item>
<item name="android:maxHeight">#dimen/ratingBarHeight</item>
</style>
And this is the xml code in the layout:
<RatingBar
android:layout_width="wrap_content"
android:layout_height="#dimen/ratingBarHeight"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:numStars="5"
android:stepSize="1.0"
style="#style/ratingBar" />
The height is defined as follows:
<dimen name="ratingBarHeight">32dip</dimen>
I had the same problem. The reason was that my drawable was smaller than #dimen/ratingBarHeight, it was 22 pixels. Changing #dimen/ratingBarHeight to 22dip fixed it for me, the strange effect disappeared.
When using a custom thumb drawable with a SeekBar view, the thumb drawable is clipped at the left and right edges of the view.
How can I fix this behavior?
You should be able to fix this by setting paddingLeft and paddingRight on your SeekBar to half the thumb width (remember to use density-independent units). You can also control the space allowed at the edges for a seek bar's thumb by calling setThumbOffset.
I ran into this issue myself, and I believe the "correct" decision would be to modify android:thumbOffset as the default style for a SeekBar sets it to 8px.
For default SeekBar I used these settings and it works fine:
android:paddingLeft="6dp"
android:paddingRight="6dp"
android:thumbOffset="8dp"
Just for clarification.
On some places I have seen
android:thumbOffset="8dp"
and some
android:thumbOffset="8px"
so I looked at the source code. this is the original style
<style name="Widget.SeekBar">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">#android:drawable/progress_horizontal</item>
<item name="android:indeterminateDrawable">#android:drawable/progress_horizontal</item>
<item name="android:minHeight">20dip</item>
<item name="android:maxHeight">20dip</item>
<item name="android:thumb">#android:drawable/seek_thumb</item>
<item name="android:thumbOffset">8dip</item>
<item name="android:focusable">true</item>
</style>
from
https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/styles.xml
I was getting the bottom of my default seekbar thumb clipped. None of the fixes here worked. I ended up using
android:clipToPadding="false"
on the parent view. This solved issue.
<androidx.appcompat.widget.AppCompatSeekBar
android:id="#+id/progress_loan_period"
android:layout_width="#dimen/dp_0"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/dp_15"
android:progressDrawable="#drawable/seek_bar"
android:thumb="#drawable/ic_slider"
android:paddingStart="#dimen/dp_0"
android:paddingEnd="#dimen/dp_0"
android:thumbOffset="-0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/label_loan_period" />
This gets the job done
Nothing worked for me but I just changed the color of the thumb different then the background color of the parent layout and it worked for me.
