Android 实现uc浏览器一样的菜单

使用AlertDialog生成菜单，利用setView()方法设置菜单视图。

布局如下：

1、菜单布局

利用GridView

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="wrap_content" android:layout_height="wrap_content"   android:orientation="vertical">   <GridView android:id="@+id/menu"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:numColumns="2"           android:verticalSpacing="5dip"           android:horizontalSpacing="5dip"           android:stretchMode="columnWidth"           android:gravity="center"></GridView>  </LinearLayout>

2、每一个item的布局

<?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="wrap_content"   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>

主程序代码如下：

代码比较简单，注释非常详细

package com.cloay.down.utils;    import java.util.ArrayList;  import java.util.HashMap;    import com.cloay.down.R;    import android.app.AlertDialog;  import android.content.Context;  import android.view.View;  import android.widget.AdapterView;  import android.widget.AdapterView.OnItemClickListener;  import android.widget.GridView;  import android.widget.SimpleAdapter;  /**   * 菜单工具类   * MenuUtil.java   * @author cloay   * 2011-10-25   */  public class MenuUtil {   private static AlertDialog menuDialog;// menu菜单Dialog   private static GridView menuGrid;      /** 菜单图片 **/   static int[] menu_image_array = { R.drawable.menu_open_in_background, R.drawable.menu_redownload, R.drawable.menu_detail, R.drawable.menu_delete };   /** 菜单文字 **/   static String[] menu_name_array = { "打开", "重新下载", "详细", "删除"};   public static void ShowMenuDialog(final Context context){    View menuView = View.inflate(context, R.layout.menu, null);    menuDialog = new AlertDialog.Builder(context)    .setView(menuView)    .create();    menuDialog.show();    menuGrid  = (GridView) menuView.findViewById(R.id.menu);    menuGrid.setAdapter(getMenuAdapter(context, menu_name_array, menu_image_array));    menuGrid.setOnItemClickListener(new OnItemClickListener() {     //监听menu按钮事件     @Override     public void onItemClick(AdapterView<?> parent, View view,       int position, long id) {      switch(position){      case 0:     //open file              break;      case 1:     //redownload 重新下载              break;      case 2:  //file details               break;      case 3:  //delete file              break;      }     }    });   }      /**    * 为menuGrid设置Adapter    * @param context    * @param menuNameArray    * @param imageResourceArray    * @return    */   private static SimpleAdapter getMenuAdapter(Context context, 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(context, data,      R.layout.item_menu, new String[] { "itemImage", "itemText" },      new int[] { R.id.item_image, R.id.item_text });    return simperAdapter;   }  }
