[펌]좌우로 드래그 하는 안드로이스드

조건은 메뉴처럼 화면 하단에 존재해야 하고 좌우로 슬라이딩 되어야 한다.

두개의 image view로 이뤄진 하단 layout은 중간에 어중간하게 슬라이딩 되어서는 안된다.

MainActivity.java

public class MainActivity extends Activity {

    private MenuSlideView mSlideView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mSlideView = (MenuSlideView)findViewById(R.id.menu_slide);
    }
}
