How to create android shape background programmatically?

Question

How to create this shape programmatically?

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:padding="10dp"     android:shape="rectangle">      <solid android:color="#e67e22"/>      <corners         android:topLeftRadius="0dp"         android:topRightRadius="0dp"         android:bottomLeftRadius="5dp"         android:bottomRightRadius="5dp"/> </shape> 

I've tried this simple function which gets corners, colors and sets that to shape:

    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.category_header);      GradientDrawable drawable = (GradientDrawable) linearLayout.getDrawable();      float[] values = { 0.2f, 0.2f, 0.2f, 0.2f };     drawable.setCornerRadii(values); 

But I got this error:

The method getDrawable() is undefined for the type LinearLayout

You can do it like this:

public static void customView(View v, int backgroundColor, int borderColor) {     GradientDrawable shape = new GradientDrawable();     shape.setShape(GradientDrawable.RECTANGLE);     shape.setCornerRadii(new float[] { 8, 8, 8, 8, 0, 0, 0, 0 });     shape.setColor(backgroundColor);     shape.setStroke(3, borderColor);     v.setBackground(shape); } 

See the documentation for the meaning of setCornerRadii params.

You can use this function throughout your app and can put border and background color of your choice.
