}

使用XML

<FrameLayout
        android:id="@+id/keyboard"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:paddingLeft="10dp"
        >
        </FrameLayout>

使用JAVA

 private void setKeyBoardFragment(){
        FragmentManager fragmentManager=getFragmentManager();
        FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
        MyKeyBoard myKeyBoard=new MyKeyBoard();
        fragmentTransaction.replace(R.id.keyboard,myKeyBoard);
        fragmentTransaction.commit();
    }
