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();
- }
- });
