Android 自定义分享列表ACTION_SEND

看到最近都在做自定义的东西，因为比较灵活，还可以摆脱系统自身不怎么漂亮的UI，(大家都懂得)所以自己也做了下自定义的分享列表，用PopupWindow的方式弹出。

先上效果图:

1、布局:

popup_share.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent" android:layout_height="wrap_content" >  <ListView android:id="@+id/share_list" android:background="#2F4F4F" android:fadingEdge="none" android:layout_width="fill_parent" android:layout_height="wrap_content" android:cacheColorHint="#00000000" android:divider="#E2DD75" android:dividerHeight="1.0dip" android:headerDividersEnabled="true" android:footerDividersEnabled="false" /></LinearLayout>

popup_share_item.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:gravity="center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="2.0dip" ><ImageView android:id="@+id/share_item_icon" android:layout_width="32.0dip" android:layout_height="32.0dip" android:layout_marginLeft="3.0dip" android:scaleType="fitXY" /><TextView android:id="@+id/share_item_name" android:gravity="center" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="分享" android:textColor="@color/white" android:singleLine="true" android:textSize="@dimen/s_size" android:layout_marginLeft="3.0dip" android:layout_marginRight="3.0dip" /></LinearLayout>

2、查询手机内所有支持分享的应用列表

public List<ResolveInfo> getShareApps(Context context) {List<ResolveInfo> mApps = new ArrayList<ResolveInfo>();Intent intent = new Intent(Intent.ACTION_SEND, null);intent.addCategory(Intent.CATEGORY_DEFAULT);intent.setType("text/plain");//intent.setType("*/*");PackageManager pManager = context.getPackageManager();mApps = pManager.queryIntentActivities(intent, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);return mApps;}

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

private List<AppInfo> getShareAppList() {List<AppInfo> shareAppInfos = new ArrayList<AppInfo>();PackageManager packageManager = getPackageManager();List<ResolveInfo> resolveInfos = getShareApps(mContext);if (null == resolveInfos) {return null;} else {for (ResolveInfo resolveInfo : resolveInfos) {AppInfo appInfo = new AppInfo();appInfo.setAppPkgName(resolveInfo.activityInfo.packageName);//showLog_I(TAG, "pkg>" + resolveInfo.activityInfo.packageName + ";name>" + resolveInfo.activityInfo.name);appInfo.setAppLauncherClassName(resolveInfo.activityInfo.name);appInfo.setAppName(resolveInfo.loadLabel(packageManager).toString());appInfo.setAppIcon(resolveInfo.loadIcon(packageManager));shareAppInfos.add(appInfo);}}return shareAppInfos;}

3、弹出PopupWindow的实现

private void initSharePopupWindow(View parent) {PopupWindow sharePopupWindow = null;View view = null;ListView shareList = null;if(null == sharePopupWindow) {//加载布局文件view = LayoutInflater.from(DetailExchangeActivity.this).inflate(R.layout.popup_share, null);shareList = (ListView) view.findViewById(R.id.share_list);List<AppInfo> shareAppInfos = getShareAppList();final ShareCustomAdapter adapter = new ShareCustomAdapter(mContext, shareAppInfos);shareList.setAdapter(adapter);shareList.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {// TODO Auto-generated method stubIntent shareIntent = new Intent(Intent.ACTION_SEND);AppInfo appInfo = (AppInfo) adapter.getItem(position);shareIntent.setComponent(new ComponentName(appInfo.getAppPkgName(), appInfo.getAppLauncherClassName()));shareIntent.setType("text/plain");//shareIntent.setType("*/*");//这里就是组织内容了，shareIntent.putExtra(Intent.EXTRA_TEXT, "测试，这里发送推广地址");shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);DetailExchangeActivity.this.startActivity(shareIntent);}});sharePopupWindow = new PopupWindow(view, (int)(160 * density), LinearLayout.LayoutParams.WRAP_CONTENT);}//使其聚焦sharePopupWindow.setFocusable(true);//设置允许在外点击消失sharePopupWindow.setOutsideTouchable(true);// 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sharePopupWindow.setBackgroundDrawable(new BitmapDrawable());//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）//showAsDropDown(parent, xPos, yPos);sharePopupWindow.showAsDropDown(parent, -5, 5);}

注：ShareCustomAdapter自己建一个就行了。(有一个图标和一个分享的名)
