ProgressBar may encounter a problem when customizing, I hope the progress in the progress bar is rounded at both ends (or the end of the progress is rounded);
Such as:

progress bar Rounder

But according to the custom shape or the layer-list is always difficult to do, almost all of the clip into a right angle;

The reason for the problem is that the following links will also have similar answers:
What do I need to have rounded corners on both sides of Android development progress?

Why is it right-angled? The reason for this is that clip is cut, so we're not enough to clip and use the scale tag. The answer to the above link is to define a. 9 picture can meet the requirements, because we are here is a solid color progress, so there is no need to make a. 9 of the picture, and only need to use the same method to refer to our definition of a shape on it;
See Code:

<ProgressBar    android:layout_below="@id/text_1"    android:layout_marginTop="16dp"    android:layout_width="match_parent"    android:layout_height="wrap_content" android:id="@+id/progressbar_1" style="?android:attr/progressBarStyleHorizontal" android:max="100" android:progress="40" android:progressDrawable="@drawable/progress_bar_drawable" />

Progressdrawable referenced by progress_bar_drawable:

<?xml version= "1.0" encoding= "Utf-8"?><Layer-listXmlns:android="Http://schemas.android.com/apk/res/android" ><ItemAndroid:id="@android: Id/background" ><Shape><Cornersandroid:toprightradius="20DP"android:bottomrightradius="20DP"/><SolidAndroid:color="#ED30353E"/></Shape></Item><ItemAndroid:id="@android: Id/secondaryprogress" ><ScaleAndroid:scalewidth="100%" ><Shape><Cornersandroid:toprightradius="20DP"android:bottomrightradius="20DP"/><SolidAndroid:color="#11ce33"/></Shape></scale> </ item> <item android:id= "@android: Id/progress" > <!--<clip> <shape> <corners android:toprightradius= "20DP" Android: bottomrightradius= "20DP"/> <solid android:color= "#FF009898"/> </shape> </clip>-<scale android:scalewidth= "100%" android:drawable= "@drawable/progress_ Bar_ct "/> </item></LAYER-LIST>            

Here's the point:

<scale android:scaleWidth="100%"            android:drawable="@drawable/progress_bar_ct" />

We have specified a custom shape:progress_bar_ct.xml

<?xml version= "1.0" encoding= "Utf-8"?><Shapexmlns:android= "http://schemas.android.com/apk/res/ Android "android:shape=" rectangle "> <!--solid Specifies the fill color of the shape, only android:color one property--<solid android:color= "#FF009898"/> <!--padding set the content area away from the boundary--<!--Corners set the fillet, Only for rectangle---<corners  Android:bottomrightradius= "20DP" android:toprightradius=< Span class= "Hljs-value" > "20DP"/> </SHAPE>    

This makes it unnecessary to customize the picture of. 9.
PS: Because my demand is the right side is rounded corner, if you need 4 corners are rounded corner only need to modify a bit of code;

<corners android:bottomRightRadius="20dp"        android:topRightRadius="20dp"/>

Modified to:

<corners android:radius="20dp" />
