想了解Android实现模仿UCweb菜单效果的方法的相关内容吗,白羽雕弓在本文为您仔细讲解Android模仿UCweb菜单效果的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Android,模仿UCweb,菜单,下面大家一起来学习吧。

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:

<?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();
 }
});
