Other layout for fragment resizing

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

            android:layout_height="match_parent"

            class="com.test.BodyFragment" >

        </fragment>

    </LinearLayout>

</LinearLayout>

Java 

LinearLayout layout1 = (LinearLayout) findViewById(R.id.layout1);

LinearLayout.LayoutParams param = layout1.getLayoutParam();

param.weight = you want value;

layout1.setLayoutParam(param);
