准备菜单数据
/** 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" };
/** 菜单图片2 **/
int[] menu_image_array2 = { R.drawable.menu_auto_landscape,
R.drawable.menu_penselectmodel, R.drawable.menu_page_attr,
R.drawable.menu_novel_mode, R.drawable.menu_page_updown,
R.drawable.menu_checkupdate, R.drawable.menu_checknet,
R.drawable.menu_refreshtimer, R.drawable.menu_syssettings,
R.drawable.menu_help, R.drawable.menu_about, R.drawable.menu_return };
/** 菜单文字2 **/
String[] menu_name_array2 = { "自动横屏", "笔选模式", "阅读模式", "浏览模式", "快捷翻页",
"检查更新", "检查网络", "定时刷新", "设置", "帮助", "关于", "返回" };
//如果是第一次打开则创建AlertDialog
@Override
public boolean onMenuOpened(int featureId, Menu menu) {
if (menuDialog == null) {
menuDialog = new AlertDialog.Builder(this).setView(menuView).show();
} else {
menuDialog.show();
}
return false;// 返回为true 则显示系统menu
}
当点击home键时取消Dialog
AlertDialog menuDialog;// menu菜单Dialog
GridView menuGrid;
View menuView;
gridview_menu.xmlmenuView = View.inflate(this, R.layout.gridview_menu, null); // 创建AlertDialog menuDialog = new AlertDialog.Builder(this).create(); menuDialog.setView(menuView); menuDialog.setOnKeyListener(new OnKeyListener() { public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_MENU)// 监听按键 dialog.dismiss(); return false; } });
取出GridView并设置Adapter<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <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>
设置点击事件,点击更和返回多时更换Adapter,
设置翻页控制变量
设置选项id,从0-11 一共12个键private boolean isMore = false;// menu菜单翻页控制
private final int ITEM_SEARCH = 0;// 搜索 private final int ITEM_FILE_MANAGER = 1;// 文件管理 private final int ITEM_DOWN_MANAGER = 2;// 下载管理 private final int ITEM_FULLSCREEN = 3;// 全屏 private final int ITEM_MORE = 11;// 菜单
获取设置GridView的Adapter Adapter绑定item_image.xmlmenuGrid = (GridView) menuView.findViewById(R.id.gridview); menuGrid.setAdapter(getMenuAdapter(menu_name_array, menu_image_array)); /** 监听menu选项 **/ menuGrid.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { switch (arg2) { case ITEM_SEARCH:// 搜索 break; case ITEM_FILE_MANAGER:// 文件管理 break; case ITEM_DOWN_MANAGER:// 下载管理 break; case ITEM_FULLSCREEN:// 全屏 break; case ITEM_MORE:// 翻页 if (isMore) { menuGrid.setAdapter(getMenuAdapter(menu_name_array2, menu_image_array2)); isMore = false; } else {// 首页 menuGrid.setAdapter(getMenuAdapter(menu_name_array, menu_image_array)); isMore = true; } menuGrid.invalidate();// 更新menu menuGrid.setSelection(ITEM_MORE); break; } } });
item_image.xml 相当于GridView中的每个选项//根据图片和文字创建Adapter 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; }
<?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="wrap_content" android:layout_height="wrap_content"></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" android:text="选项"></TextView> </RelativeLayout>
