安卓从popupwindow跳转到Activity页面

在一个已出现的poupwindow中，点击页面上的某个按钮，页面将进行跳转到另一个Activity中。popupwindow代码如下：

 1 package com.cn.gordon.exhibition.walk.popup;
 2
 3 import com.cn.gordon.exhibition.walk.activity.ForumArrangementActivity;
 4 import com.cn.gordon.exhibition.walk.activity.R;
 5 import com.cn.gordon.exhibition.walk.activity.VisitPlanActivity;
 6
 7 import android.app.Activity;
 8 import android.content.Context;
 9 import android.content.Intent;
10 import android.graphics.drawable.ColorDrawable;
11 import android.view.LayoutInflater;
12 import android.view.View;
13 import android.view.View.OnClickListener;
14 import android.widget.LinearLayout;
15 import android.widget.PopupWindow;
16 import android.widget.RelativeLayout.LayoutParams;
17
18 public class ArrangementPopupWindow extends PopupWindow {
19     private View contentView;
20     public ArrangementPopupWindow(final Activity context){
21         LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
22         contentView = inflater.inflate(R.layout.popupwindow_arrangement, null);
23         //int h = context.getWindowManager().getDefaultDisplay().getHeight();
24         int w = context.getWindowManager().getDefaultDisplay().getWidth();
25         // 设置SelectPicPopupWindow的View
26         this.setContentView(contentView);
27         // 设置SelectPicPopupWindow弹出窗体的宽
28         this.setWidth(w / 2 + 50);
29         // 设置SelectPicPopupWindow弹出窗体的高
30         this.setHeight(LayoutParams.WRAP_CONTENT);
31         // 设置SelectPicPopupWindow弹出窗体可点击
32         this.setFocusable(true);
33         this.setOutsideTouchable(true);
34         // 刷新状态
35         this.update();
36         // 实例化一个ColorDrawable颜色为半透明
37         ColorDrawable dw = new ColorDrawable(0000000000);
38         // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作
39         this.setBackgroundDrawable(dw);
40         // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
41         // 设置SelectPicPopupWindow弹出窗体动画效果
42         //this.setAnimationStyle(R.style.AnimationPreview);
43         LinearLayout layout_forum = (LinearLayout) contentView
44                 .findViewById(R.id.layout_forum);
45         LinearLayout layout_visitplan = (LinearLayout) contentView
46                 .findViewById(R.id.layout_visitplanarrangement);
47
48         layout_forum.setOnClickListener(new OnClickListener() {
49
50             @Override
51             public void onClick(View v) {
52                 if (context.getClass().equals(VisitPlanActivity.class)) {
53                     Intent in = new Intent(context,ForumArrangementActivity.class);
54                     context.startActivity(in);
55
56                 }
57                 ArrangementPopupWindow.this.dismiss();
58             }
59         });
60
61
62         layout_visitplan.setOnClickListener(new OnClickListener() {
63
64             @Override
65             public void onClick(View v) {
66                 if (context.getClass().equals(ForumArrangementActivity.class)) {
67                     Intent in = new Intent(context,VisitPlanActivity.class);
68                     context.startActivity(in);
69                 }
70
71                 ArrangementPopupWindow.this.dismiss();
72             }
73         });
74
75     }
76
77     public void showPopupWindow(View parent) {
78         if (!this.isShowing()) {
79             // 以下拉方式显示popupwindow
80             this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);
81         } else {
82             this.dismiss();
83         }
84     }
85 }

在popupwindow中需要用到上一个页面传递过来的context，通过context来调用startActivity实现页面的跳转。
