如果你想要一个矢量drawable：trapezium.xml

<vector android:height="24dp" android:viewportHeight="300.0"
android:viewportWidth="480.0" android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android">
<path android:fillColor="#E03825" android:pathData="M-18.93,275.26l505.01,-264.25l145.36,277.8l-505.01,264.25z"/>
<path android:fillColor="#FF000000"
    android:pathData="M-33.8,289.15L493,3.68"
    android:strokeColor="#000000" android:strokeWidth="14"/>

修改

然后你可以将它放在imageview前面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.lcimi.myapplication.MainActivity">
    <ImageView
        android:layout_width="match_parent"
        android:src="@drawable/back"/>
    <ImageView
        android:layout_width="match_parent"
        android:src="@drawable/trapezium"
        android:layout_marginTop="15dp"
        android:scaleType="fitXY"
        android:id="@+id/front"
        android:layout_height="300dp" />

</RelativeLayout>
