Make rounded LinearLayout

i'm creating a listview array from of LinearLayout programmatically and i want to make rounded corners so i created a drawable resource like this

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="40dp"
        />

    <padding
        android:top="2dp"
        android:bottom="2dp"
        android:left="2dp"
        android:right="2dp"/>
</shape>

The code of the LinearLayout is this

LinearLayout linearLayout= new LinearLayout(getContext());
            linearLayout.setOrientation(LinearLayout.VERTICAL);

        LinearLayout.LayoutParams layout= new LinearLayout.LayoutParams(
                200,
                100
        );


        layout.setMargins(20,20,20,20);

        linearLayout.setLayoutParams(layout);
        linearLayout.setBackgroundColor(Color.BLUE);
        linearLayout.setBackgroundResource(R.drawable.rounded);
        linearLayout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.i("Test selected","");
                v.setBackgroundColor(Color.RED);

                return false;
            }
        });

The problem is that the shape of the elements is not rounded. Where is my mistake?? Thanks to every one sorry for my english.

To make the layout having round corner:

  1. You have to define a xml file having properties of round corner having name rounded.xml in res/drawable (You can save any name)

    shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">

    <gradient
    android:endColor="#000000"
    android:startColor="#000000"/>

<corners
    android:bottomRightRadius="7dp"
    android:bottomLeftRadius="7dp"
    android:topLeftRadius="7dp"
    android:topRightRadius="7dp"/>

  2. Define your activity as:

    LinearLayout linearLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    linearLayout= new LinearLayout(getApplicationContext());
    linearLayout.setOrientation(LinearLayout.VERTICAL);

//Use framelayout.layoutparams not linearlayout.layoutparams
    FrameLayout.LayoutParams layout= new FrameLayout.LayoutParams(200,100);   

//Use setContentView to show this layout in your activity
    setContentView(linearLayout,layout);

    layout.setMargins(50,50,50,50);

    linearLayout.setLayoutParams(layout);
    linearLayout.setBackgroundColor(Color.BLUE);
    linearLayout.setBackgroundResource(R.drawable.rounded);
    linearLayout.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        Log.i("Test selected","");
        v.setBackgroundColor(Color.RED);

        return false;
    }
});

I have checked with:

        FrameLayout.LayoutParams layout= new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

And the color of layout is set to black in rounded.xml

And the output is:
