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" > |
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" /> |
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" > |
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" /> |
14 | android:id= "@+id/share_item_name" |
15 | android:gravity= "center" |
16 | android:layout_width= "wrap_content" |
17 | android:layout_height= "wrap_content" |
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" /> |
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" ); |
07 | PackageManager pManager = context.getPackageManager(); |
08 | mApps = pManager.queryIntentActivities(intent, |
09 | PackageManager.COMPONENT_ENABLED_STATE_DEFAULT); |
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) { |
08 | for (ResolveInfo resolveInfo : resolveInfos) { |
09 | AppInfo appInfo = new AppInfo(); |
10 | appInfo.setAppPkgName(resolveInfo.activityInfo.packageName); |
12 | appInfo.setAppLauncherClassName(resolveInfo.activityInfo.name); |
13 | appInfo.setAppName(resolveInfo.loadLabel(packageManager).toString()); |
14 | appInfo.setAppIcon(resolveInfo.loadIcon(packageManager)); |
15 | shareAppInfos.add(appInfo); |
3、弹出PopupWindow的实现
01 | private void initSharePopupWindow(View parent) { |
02 | PopupWindow sharePopupWindow = null ; |
04 | ListView shareList = null ; |
05 | if ( null == sharePopupWindow) { |
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); |
13 | shareList.setOnItemClickListener( new OnItemClickListener() { |
16 | public void onItemClick(AdapterView<?> parent, View view, |
17 | int position, long id) { |
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" ); |
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); |
31 | sharePopupWindow = new PopupWindow(view, |
32 | ( int )( 160 * density), LinearLayout.LayoutParams.WRAP_CONTENT); |
35 | sharePopupWindow.setFocusable( true ); |
37 | sharePopupWindow.setOutsideTouchable( true ); |
39 | sharePopupWindow.setBackgroundDrawable( new BitmapDrawable()); |
42 | sharePopupWindow.showAsDropDown(parent, - 5 , 5 ); |
