Android自訂系統分享面板

標籤：android   系統分享   自訂分享   

在Android中實現分享有一種比較方便的方式，調用系統的分享面板來分享我們的應用。最基本的實現如下：

public Intent getShareIntent(){Intent intent = new Intent();intent.setAction(Intent.ACTION_SEND);intent.putExtra(Intent.EXTRA_TEXT, "這是測試分享面板, http://www.baidu.comss");intent.setType("text/plain");return intent;}

還有一種是實現在ActionBar上添加分享列表，實現代碼如下：

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android">      <item android:id="@+id/menu_item_share"          android:showAsAction="ifRoom"          android:title="Share"          android:actionProviderClass="android.widget.ShareActionProvider" />  </menu> 

@Overridepublic boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.actionbar_menu, menu);MenuItem item = menu.findItem(R.id.menu_item_share);shareActionProvider = (ShareActionProvider) item.getActionProvider();Intent shareIntent = getShareIntent();shareActionProvider.setShareIntent(shareIntent);return true;}public Intent getShareIntent(){Intent intent = new Intent();intent.setAction(Intent.ACTION_SEND);intent.putExtra(Intent.EXTRA_TEXT, "這是測試分享面板, http://www.baidu.comss");intent.setType("text/plain");return intent;}

系統預設會為我們找出所有支援seteType中類型的應用，同樣我們可以實現自訂分享的平台。

private void initShareIntent() {Intent intent = new Intent(Intent.ACTION_SEND);intent.setType("text/plain");List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(intent, 0);if (!resInfo.isEmpty()) {List<Intent> targetedShareIntents = new ArrayList<Intent>();for (ResolveInfo info : resInfo) {Intent targeted = new Intent(Intent.ACTION_SEND);targeted.setType("text/plain");ActivityInfo activityInfo = info.activityInfo;//在這裡可以添加相應的平台，用 || 串連if (activityInfo.packageName.contains("com.tencent.mm")) {targeted.putExtra(Intent.EXTRA_TEXT, "分享內容");targeted.setPackage(activityInfo.packageName);targetedShareIntents.add(targeted);}}Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");if (chooserIntent == null) {return;}chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,targetedShareIntents.toArray(new Parcelable[] {}));try {startActivity(chooserIntent);} catch (android.content.ActivityNotFoundException ex) {Toast.makeText(this, "Can‘t find sharecomponent to share",Toast.LENGTH_SHORT).show();}}}

系統的分享面板存在一些缺陷，比如每個手機顯示的面板的樣式不同，不同手機上顯示的分享平台種類和數目不同，會出現一些雜亂的應用。我們可以給上面的方法添加參數，讓只能分享到一個平台就可以解決這個問題，這樣我們就可以自訂一個分享面板，來添加我們想要的應用，代碼如下：

private void initShareIntent(String type) {      boolean found = false;      Intent share = new Intent(android.content.Intent.ACTION_SEND);      share.setType("image/*");      // gets the list of intentsthat can be loaded.      List<ResolveInfo> resInfo =getPackageManager().queryIntentActivities(           share, 0);      if (!resInfo.isEmpty()) {        for (ResolveInfo info : resInfo) {           if (info.activityInfo.packageName.toLowerCase().contains(type)                 || info.activityInfo.name.toLowerCase().contains(type)) {              share.putExtra(Intent.EXTRA_SUBJECT, "subject");              share.putExtra(Intent.EXTRA_TEXT, "your text");              //share.putExtra(Intent.EXTRA_STREAM,              // Uri.fromFile(newFile(myPath))); // Optional, just              // // if you wanna              // // share an              // // image.              share.setPackage(info.activityInfo.packageName);              found = true;              break;           }        }        if (!found)           return;        startActivity(Intent.createChooser(share, "Select"));      }   }
