仿UC自定义动态菜单

UCWeb的菜单看起来不错，自己想模仿做一个，苦恼一直没有思路

google了几天，终于找到一个帖子  http://www.eoeandroid.com/viewthread.php?tid=28824

按照上面提供的思路实现了

 

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

1、布局文件

popupwindow.xml

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:background="#50000000"
  android:layout_height="fill_parent"
  android:gravity="bottom|center_horizontal">
  <LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="320dip"
      android:background="@drawable/bkg2"
      android:id="@+id/popdialog"
      android:layout_height="250dip"
      android:gravity="center_vertical|center_horizontal"
      >
      <GridView
         android:id="@+id/gridview"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:numColumns="4"
         android:verticalSpacing="10dip"
         android:horizontalSpacing="10dip"
         android:stretchMode="columnWidth"
         android:gravity="center"
         />
    </LinearLayout>
</LinearLayout>

 

 

 

item_menu.xml

 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RelativeLayout_Item"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:paddingBottom="5dip">
    <ImageView android:id="@+id/item_image"
        android:layout_centerHorizontal="true"
        android:layout_width="40dip"
        android:layout_height="40dip">
        </ImageView>
    <TextView android:layout_below="@id/item_image"
        android:id="@+id/item_text"
        android:layout_centerHorizontal="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@style/Text.Location"
        android:text="选项"></TextView>
</RelativeLayout>

 

 

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

 

 

/** 菜单图片 **/
    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 };
    /** 菜单文字 **/
    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" };

 

 

 

 /**
  * 构造菜单Adapter
  *
  * @param menuNameArray
  *            名称
  * @param imageResourceArray
  *            图片
  * @return SimpleAdapter
  */
 private SimpleAdapter getMenuAdapter(String[] menuNameArray,
   int[] imageResourceArray) {
   ArrayList<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>();
   for (int i = 0; i < menuNameArray.length; i++) {
        HashMap<String, Object> map = new HashMap<String, Object>();
        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();
            }
        });

 

6、界面截图
