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

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`	`publicList<ResolveInfo> getShareApps(Context context) {`

`02`	`List<ResolveInfo> mApps =newArrayList<ResolveInfo>();`

`03`	`Intent intent =newIntent(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`	`returnmApps;`

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`	`privateList<AppInfo> getShareAppList() {`

`02`	`List<AppInfo> shareAppInfos =newArrayList<AppInfo>();`

`03`	`PackageManager packageManager = getPackageManager();`

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

`05`	`if(null== resolveInfos) {`

`06`	`returnnull;`

07 }else{

`08`	`for(ResolveInfo resolveInfo : resolveInfos) {`

`09`	`AppInfo appInfo =newAppInfo();`

`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`	`returnshareAppInfos;`

19 }

3、弹出PopupWindow的实现

view source print ?

`01`	`privatevoidinitSharePopupWindow(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`	`finalShareCustomAdapter adapter =newShareCustomAdapter(mContext, shareAppInfos);`

`11`	`shareList.setAdapter(adapter);`

12

`13`	`shareList.setOnItemClickListener(newOnItemClickListener() {`

14

`15`	`@Override`

`16`	`publicvoidonItemClick(AdapterView<?> parent, View view,`

`17`	`intposition,longid) {`

`18`	`// TODO Auto-generated method stub`

`19`	`Intent shareIntent =newIntent(Intent.ACTION_SEND);`

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

`21`	`shareIntent.setComponent(newComponentName(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 =newPopupWindow(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(newBitmapDrawable());`

`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 }
