-------------------------------------------------------------------------------------------

 

1、布局:

popup_share.xml

01	<?xml version="1.0" encoding="utf-8"?>

02	<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

03	android:layout_width="fill_parent"

04	android:layout_height="wrap_content" >

05

<ListView

06	android:id="@+id/share_list"

07	android:background="#2F4F4F"

08	android:fadingEdge="none"

09	android:layout_width="fill_parent"

10	android:layout_height="wrap_content"

11	android:cacheColorHint="#00000000"

12	android:divider="#E2DD75"

13	android:dividerHeight="1.0dip"

14	android:headerDividersEnabled="true"

15	android:footerDividersEnabled="false" />

16	</LinearLayout>

popup_share_item.xml

01	<?xml version="1.0" encoding="utf-8"?>

02	<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

03	android:gravity="center_vertical"

04	android:layout_width="wrap_content"

05	android:layout_height="wrap_content"

06	android:padding="2.0dip" >

07	<ImageView

08	android:id="@+id/share_item_icon"

09	android:layout_width="32.0dip"

10	android:layout_height="32.0dip"

11	android:layout_marginLeft="3.0dip"

12	android:scaleType="fitXY" />

13

<TextView

14	android:id="@+id/share_item_name"

15	android:gravity="center"

16	android:layout_width="wrap_content"

17	android:layout_height="wrap_content"

18	android:text="分享"

19	android:textColor="@color/white"

20	android:singleLine="true"

21	android:textSize="@dimen/s_size"

22	android:layout_marginLeft="3.0dip"

23	android:layout_marginRight="3.0dip" />

24	</LinearLayout>

2、查询手机内所有支持分享的应用列表

 

 

01	public List<ResolveInfo> getShareApps(Context context) {

02	List<ResolveInfo> mApps = new ArrayList<ResolveInfo>();

03	Intent intent = new Intent(Intent.ACTION_SEND, null);

04	intent.addCategory(Intent.CATEGORY_DEFAULT);

05	intent.setType("text/plain");

06	//      intent.setType("*/*");

07	PackageManager pManager = context.getPackageManager();

08	mApps = pManager.queryIntentActivities(intent,

09	PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);

10	return mApps;

11

}

注：ApplicationInfo是从一个特定的应用得到的信息。这些信息是从相对应的Androdimanifest.xml的< application>标签中收集到的。

ResolveInfo这个类是通过解析一个与IntentFilter相对应的intent得到的信息。它部分地对应于从AndroidManifest.xml的< intent>标签收集到的信息。

得到List列表，我自建的AppInfo类，自己建一个就行

01	private List<AppInfo> getShareAppList() {

02	List<AppInfo> shareAppInfos = new ArrayList<AppInfo>();

03	PackageManager packageManager = getPackageManager();

04	List<ResolveInfo> resolveInfos = getShareApps(mContext);

05	if (null == resolveInfos) {

06	return null;

07

} else {

08	for (ResolveInfo resolveInfo : resolveInfos) {

09	AppInfo appInfo = new AppInfo();

10	appInfo.setAppPkgName(resolveInfo.activityInfo.packageName);

11	//              showLog_I(TAG, "pkg>" + resolveInfo.activityInfo.packageName + ";name>" + resolveInfo.activityInfo.name);

12	appInfo.setAppLauncherClassName(resolveInfo.activityInfo.name);

13	appInfo.setAppName(resolveInfo.loadLabel(packageManager).toString());

14	appInfo.setAppIcon(resolveInfo.loadIcon(packageManager));

15	shareAppInfos.add(appInfo);

16

}

17

}

18	return shareAppInfos;

19

}

3、弹出PopupWindow的实现

 

 

view source

 

print ?

01	private void initSharePopupWindow(View parent) {

02	PopupWindow sharePopupWindow = null;

03	View view = null;

04	ListView shareList = null;

05	if(null == sharePopupWindow) {

06

//加载布局文件

07	view = LayoutInflater.from(DetailExchangeActivity.this).inflate(R.layout.popup_share, null);

08	shareList = (ListView) view.findViewById(R.id.share_list);

09	List<AppInfo> shareAppInfos = getShareAppList();

10	final ShareCustomAdapter adapter = new ShareCustomAdapter(mContext, shareAppInfos);

11	shareList.setAdapter(adapter);

12

13	shareList.setOnItemClickListener(new OnItemClickListener() {

14

15

@Override

16	public void onItemClick(AdapterView<?> parent, View view,

17	int position, long id) {

18	// TODO Auto-generated method stub

19	Intent shareIntent = new Intent(Intent.ACTION_SEND);

20	AppInfo appInfo = (AppInfo) adapter.getItem(position);

21	shareIntent.setComponent(new ComponentName(appInfo.getAppPkgName(), appInfo.getAppLauncherClassName()));

22	shareIntent.setType("text/plain");

23	//                  shareIntent.setType("*/*");

24	//这里就是组织内容了，

25	shareIntent.putExtra(Intent.EXTRA_TEXT, "测试，这里发送推广地址");

26	shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

27	DetailExchangeActivity.this.startActivity(shareIntent);

28

}

29

});

30

31	sharePopupWindow = new PopupWindow(view,

32	(int)(160 * density), LinearLayout.LayoutParams.WRAP_CONTENT);

33

}

34

//使其聚焦

35	sharePopupWindow.setFocusable(true);

36	//设置允许在外点击消失

37	sharePopupWindow.setOutsideTouchable(true);

38	// 这个是为了点击“返回Back”也能使其消失，并且并不会影响你的背景

39	sharePopupWindow.setBackgroundDrawable(new BitmapDrawable());

40	//xoff,yoff基于anchor的左下角进行偏移。正数表示下方右边，负数表示（上方左边）

41	//showAsDropDown(parent, xPos, yPos);

42	sharePopupWindow.showAsDropDown(parent, -5, 5);

43

}
