By default the ProgressBar has a certain padding above and below the bar itself. Is there a way to remove this padding so as to only have the bar in the end?
I use the following as a workaround for this issue.
android:layout_marginBottom="-8dp"
android:layout_marginTop="-4dp"
This is how I used Juozas's answer:
height of my ProgressBar is 4dp. So I created a FrameLayout with height 4dp and set the layout_gravity of ProgressBar to center. It's works like a charm.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="4dp">
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_gravity="center"
android:indeterminate="true"/>
</FrameLayout>
I ended up using a custom library to solve this issue. Most of the other solutions work but the results are not consistent across various devices.
MaterialProgressBar
- Consistent appearance on Android 4.0+.
- Correct tinting across platforms.
- Able to remove the intrinsic padding of framework ProgressBar.
- Able to hide the track of framework horizontal ProgressBar.
- Used as a drop-in replacement for framework ProgressBar.
To add as a gradle dependency:
compile 'me.zhanghai.android.materialprogressbar:library:1.1.7'
To add a ProgressBar with no intrinsic padding to your layout:
<me.zhanghai.android.materialprogressbar.MaterialProgressBar
android:layout_width="wrap_content"
android:layout_height="4dp"
android:indeterminate="true"
app:mpb_progressStyle="horizontal"
app:mpb_useIntrinsicPadding="false"
style="@style/Widget.MaterialProgressBar.ProgressBar.Horizontal" />
app:mpb_useIntrinsicPadding="false" does the trick. For more details see the GitHub page.
A complete solution to this problem would be as follows. Just in case if someone needs code fragments, this is what I did.
- Copied all the 8 indeterminate horizontal progressbar drawables
- Edited the drawables using some image manipulator and remove unnecessary paddings
- Copied the drawable XML named progress_indeterminate_horizontal_holo.xml from android platform
- Copied the style Widget.ProgressBar.Horizontal and its parents
- Set the style and min_height manually in the layout
Here is the progress_indeterminate_horizontal_holo.xml
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item android:drawable="@drawable/progressbar_indeterminate_holo1" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo2" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo3" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo4" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo5" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo6" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo7" android:duration="50" />
<item android:drawable="@drawable/progressbar_indeterminate_holo8" android:duration="50" />
Style resources copied to my local styles file.
<style name="Widget">
<item name="android:textAppearance">@android:attr/textAppearance</item>
</style>
<style name="Widget.ProgressBar">
<item name="android:indeterminateOnly">true</item>
<item name="android:indeterminateBehavior">repeat</item>
<item name="android:indeterminateDuration">3500</item>
</style>
<style name="Widget.ProgressBar.Horizontal">
<item name="android:indeterminateOnly">false</item>
<item name="android:indeterminateDrawable">@drawable/progress_indeterminate_horizontal_holo</item>
</style>
And finally, set min height to 4dp in my local layout file.
<ProgressBar
android:id="@+id/pb_loading"
style="@style/Widget.ProgressBar.Horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:indeterminate="true"
android:minHeight="4dp"
android:minWidth="48dp"
android:progressDrawable="@drawable/progress_indeterminate_horizontal_holo" />
It's possible to draw vertically centered ProgressBar inside a parent that would clip away the padding. Since ProgressBar cannot draw itself bigger than parent, we must create a big parent to place inside a clipping view.
<FrameLayout
android:id="@+id/clippedProgressBar"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="4dp"
tools:ignore="UselessParent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="16dp"
android:layout_gravity="center_vertical">
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:indeterminate="true"/>
</FrameLayout>
</FrameLayout>
If someone still needs help can try this:
<androidx.core.widget.ContentLoadingProgressBar
android:id="@+id/progress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="@+id/guideline" android:indeterminate="true"
android:visibility="visible" app:layout_constraintBottom_toTopOf="@+id/guideline"/>
Here, the progress bar is inside the ConstraintLayout, and the constraintTop_toTopOf and constraintBottom_toTopOf attributes must be applied to the same element (in this case, it is guideline).
I met the same problem while using progressbar with Horizontal style.
The root cause is that the default 9-patch drawable for progress bar: (progress_bg_holo_dark.9.png) has some vertical transparent pixels as padding.
The final Solution that worked for me: customize the progress drawable, my sample code as follow:
custom_horizontal_progressbar_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape android:shape="rectangle">
<solid android:color="#33ffffff" />
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape android:shape="rectangle">
<solid android:color="#ff9800" />
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape android:shape="rectangle">
<solid android:color="#E91E63" />
</shape>
</clip>
</item>
</layer-list>
layout snippet:
<ProgressBar
android:id="@+id/song_progress_normal"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_alignParentBottom="true"
android:progressDrawable="@drawable/custom_horizontal_progressbar_drawable"
android:progress="0"/>
Subin's answer seems to be the only one (currently) that isn't a fragile hack subject to breakage in future releases of the Android ProgressBar.
But rather than going through the trouble of breaking out the resources, modifying them, and maintaining them indefinitely, I've opted to use the MaterialProgressBar library, which does that for us:
<me.zhanghai.android.materialprogressbar.MaterialProgressBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminate="true"
android:layout_gravity="bottom"
custom:mpb_progressStyle="horizontal"
custom:mpb_showTrack="false"
custom:mpb_useIntrinsicPadding="false"
style="@style/Widget.MaterialProgressBar.ProgressBar.Horizontal.NoPadding"
/>
In build.gradle:
// Android horizontal ProgressBar doesn't allow removal of top/bottom padding
compile 'me.zhanghai.android.materialprogressbar:library:1.1.6'
That project has a nice demo that shows the differences between it and the built-in ProgressBar.
One trick is to add negative margins to your progress bar.
Below is an example of the XML code, assuming it's on top of your screen:
<ProgressBar
android:id="@+id/progressBar"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="-7dp"
android:layout_marginBottom="-7dp"
android:indeterminate="true" />
I use minHeight and maxHeigh. It helps for different Api versions.
<ProgressBar
android:id="@+id/progress_bar"
style="@style/Base.Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxHeight="3dp"
android:minHeight="3dp" />
It needs to use both. Api 23 works nice with
android:layout_height="wrap_content"
android:minHeight="0dp"
But lower Api versions increase progress bar height to maxHeight in that case.
To remove the vertial padding of ProgressBar, you can do by
- fix the height of
ProgressBar - Use scaleY="value" (value = height/4) (4 is default height of progress bar)
Example contains 1 wrap_content ProgressBar, 1 8dp ProgressBar, 1 100dp ProgressBar
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
...
android:layout_height="8dp"
android:scaleY="2" />
adding the android:progressDrawable to a layer-list defined in drawable fixed the issue for me. It works by masking the progess bar in a custom drawable
example implementation described at https://stackoverflow.com/a/4454450/1145905
I'm using style="@style/Widget.AppCompat.ProgressBar.Horizontal" and it was fairly easy to get rid of the margins. That style is:
<item name="progressDrawable">@drawable/progress_horizontal_material</item>
<item name="indeterminateDrawable">@drawable/progress_indeterminate_horizontal_material</item>
<item name="minHeight">16dip</item>
<item name="maxHeight">16dip</item>
I just overrode the min/max height:
<ProgressBar
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="2dp"
android:indeterminate="true"
android:minHeight="2dp"
android:maxHeight="2dp" />
Try the following:
<ProgressBar
android:id="@+id/progress_bar"
style="@android:style/Widget.ProgressBar.Horizontal"
android:progress="25"
android:progressTint="@color/colorWhite"
android:progressBackgroundTint="@color/colorPrimaryLight"
android:layout_width="match_parent"
android:layout_height="4dp" />
... and then configure the progress bar to your needs since it'll initially display a mid-sized bar with a yellow-colored progress tint with a grayish progress background tint. Also, notice that there's no vertical padding.
<ProgressBar
android:layout_marginTop="-8dp"
android:layout_marginLeft="-8dp"
android:layout_marginRight="-8dp"
android:id="@+id/progress_bar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="4dp"
android:indeterminate="false"
android:indeterminateTint="@color/white"
android:max="100"
android:paddingStart="8dp"
android:paddingRight="0dp"
android:progressDrawable="@drawable/progress_bg" />
Not necessary to download any new module or even put a FrameLayout around your Progress Bar. These are all just hacks. Only 2 steps:
In your whatever.xml
<ProgressBar
android:id="@+id/workoutSessionGlobalProgress"
android:layout_width="match_parent"
android:layout_height="YOUR_HEIGHT"
android:progressDrawable="@drawable/progress_horizontal"
android:progress="0"
<!-- High value to make ValueAnimator smoother -->
android:max="DURATION * 1000"
android:indeterminate="false"
style="@style/Widget.MaterialProgressBar.ProgressBar.Horizontal"/>
progress_horizontal.xml, Change the values as you please.
Don't like the rounded corners?
Remove corner radius
Don't like the colors? Change the colors, etc. Done!
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ff9d9e9d"
android:centerColor="#ff5a5d5a"
android:centerY="0.75"
android:endColor="#ff747674"
android:angle="270"
/>
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#80ffd300"
android:centerColor="#80ffb600"
android:centerY="0.75"
android:endColor="#a0ffcb00"
android:angle="270"
/>
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ffffd300"
android:centerColor="#ffffb600"
android:centerY="0.75"
android:endColor="#ffffcb00"
android:angle="270"
/>
</shape>
</clip>
</item>
</layer-list>
Generally, these are the steps to change the code of anything you don't like. Just find the source code and figure out what to change. If you follow the ProgressBar source code, you will find a file called progress_horizontal.xml that it references. Basically how I solve all my XML problems.
The best solution should be
android:minHeight="0dp"
No workaround and works like a charm.
A simple no-tricks solution which is compatible with any version of Android and doesn't need external libraries is faking ProgressBar with two Views inside LinearLayout. This is what I ended up with. Looks pretty neat and this approach is quite flexible - you can animate it in funky ways, add text etc.
Layout:
<LinearLayout
android:id="@+id/inventory_progress_layout"
android:layout_width="match_parent"
android:layout_height="4dp"
android:orientation="horizontal">
<TextView
android:id="@+id/inventory_progress_value"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TextView
android:id="@+id/inventory_progress_remaining"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Code:
public void setProgressValue(float percentage) {
TextView progressValue = (TextView) findViewById(R.id.inventory_progress_value);
TextView progressRemaining = (TextView) findViewById(R.id.inventory_progress_remaining);
LinearLayout.LayoutParams paramsValue = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
LinearLayout.LayoutParams paramsRemaining = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
paramsValue.weight = (100 - percentage);
paramsRemaining.weight = percentage;
progressValue.setLayoutParams(paramsValue);
progressRemaining.setLayoutParams(paramsRemaining);
}
Result (with some elevation added):
