Стойкий нижний лист

Question

У меня есть постоянный нижний лист с рамкой. Я хочу сделать полноэкранный нижний лист, но не могу.

}


public void setFragment(int state) {
    if (state == 0) {
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        Fragment1 fragment1 = new Fragment1();
        ft.replace(R.id.frame, fragment1);
        ft.commit();
    }else if (state==1){
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        Fragment2 fragment2 = new Fragment2();
        ft.replace(R.id.frame, fragment2);
        ft.commit();
    }
}

}

fragment1.xml

    android:text="frahment1" />

fragment2.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

Когда я щелкаю, чтобы открыть нижний лист, нижний лист раскрывается, но фрагмент не является полноэкранным, это всего лишь textView, что есть во фрагменте.
