1、在xml中添加ProgressBar控件

 <ProgressBar
            android:id="@+id/pbTestProcess"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="250dp"
            android:layout_height="5dp"
            android:layout_marginTop="73dp"
            android:max="100"
            android:mirrorForRtl="true"
            android:progressDrawable="@drawable/test_progress_bar"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            android:progress="60"
            tools:ignore="MissingConstraints" />

2、实现圆角的drawable文件test_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape>
            <corners android:radius="4dp" />
            <solid android:color="#CFEAFE" />
        </shape>
    </item>
    <item>
        <scale android:scaleWidth="100%">
            <shape>
                <corners android:radius="4dp" />
                <solid android:color="#FF0000" />
            </shape>
        </scale>
    </item>
</layer-list>
