Creating an Image view of given shape in android

问题

I need to create an imageview of this particular shape in Android. If cropping an image in this shape is possible, then also its fine. Please help me out with it?

This will be the complete set

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:src="@drawable/gohan" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:src="@drawable/triangle_shape" />
</FrameLayout>

triangle_shape.xml this will be inside your drawable directory

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <rotate
            android:fromDegrees="-70" // you will have to tweak this a little for adjustment
            android:pivotX="100%"
            android:pivotY="75%"
            android:toDegrees="40">
            <shape android:shape="rectangle">
                <stroke
                    android:width="10dp"
                    android:color="@android:color/transparent" />
                <solid android:color="@android:color/holo_blue_bright" />
            </shape>
        </rotate>
    </item>
</layer-list>

Output
