Android实现模仿UCweb菜单效果的方法

本文实例讲述了Android实现模仿UCweb菜单效果的方法。分享给大家供大家参考。具体如下：

UCWeb的菜单看起来不错，自己模仿做一个，思路实现如下：

1、保留menu按键作用
2、用popupwindow作为菜单显示容器
3、用GridView显示所有子菜单

代码如下：

1、布局文件：

popupwindow.xml：

item_menu.xml：

2、用popupwindow作为菜单显示容器：

View view = this.getLayoutInflater().inflate(R.layout.popwindowdemo, null);
pop = new PopupWindow(view,320,450);//大小设置为全屏幕，这里硬编码的，可修改
pop.setOutsideTouchable(false);
pop.setBackgroundDrawable(new BitmapDrawable());
pop.setFocusable(true);//如果不加这个，Grid不会响应ItemClick
pop.setTouchInterceptor(new onTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
 // TODO Auto-generated method stub
 if (event.getY()<240){ //这里处理，当点击gridview以外区域的时候，菜单关闭
  if (pop.isShowing())
   pop.dismiss();
 }
 Log.d("Demo", "popupWindow::onTouch >>> view: "
   + v + ", event: " + event);
 return false;
}
});

3、初始化gridview：

int[] menu_image_array = { R.drawable.menu_search,
   R.drawable.menu_filemanager, R.drawable.menu_downmanager,
   R.drawable.menu_fullscreen, R.drawable.menu_inputurl,
   R.drawable.menu_bookmark, R.drawable.menu_bookmark_sync_import,
   R.drawable.menu_sharepage, R.drawable.menu_quit,
   R.drawable.menu_nightmode, R.drawable.menu_refresh,
   R.drawable.menu_more };

String[] menu_name_array = { "搜索", "文件管理", "下载管理", "全屏", "网址", "书签",
 "加入书签", "分享页面", "退出", "夜间模式", "刷新", "更多" };

private SimpleAdapter getMenuAdapter(String[] menuNameArray,
int[] imageResourceArray) {
 ArrayList> data = new ArrayList>();
 for (int i = 0; i < menuNameArray.length; i++) {
  HashMap map = new HashMap();
  map.put("itemImage", imageResourceArray[i]);
  map.put("itemText", menuNameArray[i]);
  data.add(map);
 }
 SimpleAdapter simperAdapter = new SimpleAdapter(this, data,
  R.layout.item_menu, new String[] { "itemImage", "itemText" },
  new int[] { R.id.item_image, R.id.item_text });
  return simperAdapter;
}
menuGrid = (GridView) view.findViewById(R.id.gridview);  
menuGrid.setAdapter(getMenuAdapter(menu_name_array, menu_image_array));

4、注册Menu弹起事件：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
 // TODO Auto-generated method stub
 pop.showAtLocation(findViewById(R.id.mainfrm), Gravity.CENTER|Gravity.BOTTOM, 0, 0);
 return false;//super.onCreateOptionsMenu(menu); 
}

5、注册menu子菜单单击事件：

menuGrid.setonItemClickListener(new onItemClickListener() {
 public void onItemClick(AdapterView arg0, View arg1, int arg2,
   long arg3) {
  Log.v("Demo", "menuGrid.setOnItemClickListener: "+arg2+" "+arg3);
  Toast.makeText(UIMenu.this, "Click"+arg2, Toast.LENGTH_SHORT).show();
  if (pop.isShowing()) //关闭菜单
   pop.dismiss();
 }
});
