在主程序直接使用：

mMenu = (MyCustomVIEw) findVIEwByID(R.ID.ID_menu);mMenu.setonMenuItemClickListener(new MyCustomVIEw.OnMenuItemClickListener() {  @OverrIDe  public voID onClick(VIEw vIEw,int pos) {    Toast.makeText(MainActivity.this,pos + ":" + vIEw.getTag(),Toast.LENGTH_SHORT).show();  }});mMenu.setontouchListener(new VIEw.OntouchListener() {  @OverrIDe  public boolean ontouch(VIEw v,MotionEvent event) {    if(mMenu.isopen()){      mMenu.toggleMenu(300);    }    return false;  }});
