最佳答案

It is Widget.ProgressBar.Horizontal on my phone, if I set android:indeterminate="true"

Just add a STYLE line and your progress becomes horizontal:

<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/progress"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:max="100"
android:progress="45"/>

Progress Bar in Layout

<ProgressBar
android:id="@+id/download_progressbar"
android:layout_width="200dp"
android:layout_height="24dp"
android:background="@drawable/download_progress_bg_track"
android:progressDrawable="@drawable/download_progress_style"
style="?android:attr/progressBarStyleHorizontal"
android:indeterminate="false"
android:indeterminateOnly="false" />

download_progress_style.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/progress">
<scale
android:useIntrinsicSizeAsMinimum="true"
android:scaleWidth="100%"
android:drawable="@drawable/store_download_progress" />
</item>
</layer-list>

store_download_progress.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ff207d94" />
</shape>

For using the new progress bar

style="?android:attr/progressBarStyleHorizontal"

for the old grey color progress bar use

style="@android:style/Widget.ProgressBar.Horizontal"

in this one you have the option of changing the height by setting minHeight

The complete XML code is:

<ProgressBar
android:id="@+id/pbProcessing"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tvProcessing"
android:indeterminateOnly="true"/>

indeterminateOnly is set to true for getting indeterminate horizontal progress bar

Worked for me , can try with the same

<ProgressBar
android:id="@+id/determinateBar"
android:indeterminateOnly="true"
android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal"
android:indeterminateDuration="10"
android:indeterminateBehavior="repeat"
android:progressBackgroundTint="#208afa"
android:progressBackgroundTintMode="multiply"
android:minHeight="24dip"
android:maxHeight="24dip"
android:layout_width="match_parent"
android:layout_height="10dp"
android:visibility="visible"/>

Now you can create it easily using LinearProgressIndicator from the material design with a lot of customization for example

<com.google.android.material.progressindicator.LinearProgressIndicator
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminate="true" />

Check MaterialDesign link for more information and code examples

If you want a progress bar like this:

Then you can add this style to you progress bar:

?android:attr/progressBarStyleHorizontal

Then your progress bar would look like this:

<ProgressBar
android:id="@+id/loading"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="?android:attr/progressBarStyleHorizontal"
android:progress="10"
android:layout_margin="10dp"
android:indeterminate="false" />
