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();
     }
