How to draw triangle shape in android xml
Try this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@+id/rightArrow">
<rotate
android:fromDegrees="45"
android:toDegrees="45"
android:pivotX="-40%"
android:pivotY="87%" >
<shape
android:shape="rectangle" >
<stroke android:color="@android:color/transparent" android:width="10dp"/>
<solid
android:color="#000000" />
</shape>
</rotate>
</item>
</layer-list>
For the desired direction of triangle you can play with the degrees and pivotx/y points
e.g
<rotate
android:fromDegrees="220"
android:toDegrees="0"
android:pivotX="35%"
android:pivotY="5%" >
<shape
android:shape="rectangle" >
<stroke android:color="#000000" android:width="1dp"/>
<solid
android:color="#000000" />
</shape>
</rotate>
will give you 'v' shaped triangle
alternate for rotate
this property also given v shape triangle
android:rotation="180"
Android: Make a button with triangle shape using xml definitions (drawable)
If someone still has issues with this :
xml:
<item android:top="45dp">
<shape>
<size android:height="100dp" android:width="90dp"/>
<solid android:color="@android:color/holo_orange_light" />
</shape>
</item>
<item android:top="36dp" android:left="11dp">
<rotate
android:fromDegrees="45"
android:toDegrees="0"
android:pivotX="80%"
android:pivotY="20%" >
<shape>
<size android:width="40dp"
android:height="30dp"/>
<stroke android:color="@android:color/holo_orange_light" android:width="1dp"/>
<solid android:color="@android:color/holo_orange_light" />
</shape>
</rotate>
</item>
</layer-list>override TextView and use it in your layout:
public class CustomTextView extends TextView {
private int mWidth;
private int mHeight;
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint mPaint = new Paint();
int color = getResources().getColor(R.color.YourColor);
mPaint.setColor(color);
Path mPath = new Path();
mPath.moveTo(.0f, this.getHeight());
mPath.lineTo(0.8f * this.getWidth(), this.getHeight());
mPath.lineTo(this.getWidth(), 0.5f * this.getHeight());
mPath.lineTo(0.8f * this.getWidth(), .0f);
mPath.lineTo(.0f, .0f);
mPath.lineTo(.0f, this.getHeight());
canvas.clipPath(mPath);
canvas.drawPath(mPath,mPaint);
}
}
Regarding the xml example: there are two rectangles overlapping.You have to play around with the values a lot and this makes it difficult to use on different views. I think using a custom view is the best solution in this case.

How to create Triangle shaped drawable?
drawable-backround_triangle.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate
android:fromDegrees="45"
android:toDegrees="45"
android:pivotX="250%"
android:pivotY="80%">

android:How to make triangular layout
You can create this custom shape using <layer-list>. Below is a working example. Put custom_triangular_shape.xml into your res/drawable folder.
custom_triangular_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Transparent Rectangle -->
<item>
<shape android:shape="rectangle">
<size
android:width="300dp"
android:height="80dp" />
<solid android:color="@android:color/transparent" />
</shape>
</item>
<!-- Colored Rectangle -->
<item
android:bottom="20dp">
<shape android:shape="rectangle">
<corners
android:radius="4dp">
</corners>
<size
android:width="300dp"
android:height="80dp" />
<solid android:color="#FFFFFF" />
</shape>
</item>
<!-- Bottom Triangle -->
<item
android:left="90dp"
android:right="110dp"
android:top="0dp"
android:bottom="30dp">
<rotate android:fromDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" />
</shape>
</rotate>
</item>
</layer-list>
USE:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/custom_triangular_shape">
</LinearLayout>
