NOTE：这只是简单的实现，没有使用各自的SDK。基本思路是通过包名和类名来直接操作的。如果app修改了名字，可能就需要对应的修改报名和类名。

之前有分享到微信，QQ的代码，自行查找，就在上一篇博客。接着写：

新浪微博：

public class ShareToXinlangWeibo {	private static final String PackageName = "com.sina.weibo";	private static final String ActivityName = "com.sina.weibo.EditActivity";	public static void share(Activity activity,String msg, ArrayList
    
      images) {		if (AppInstallHelper.isInstalled(activity, PackageName,				ActivityName)) {			Intent intent = new Intent();			intent.setAction(Intent.ACTION_SEND_MULTIPLE);			intent.putExtra(Intent.EXTRA_TEXT, msg);			intent.setType("image/jpeg"); 			intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, images);			intent.setClassName(PackageName, ActivityName);			activity.startActivity(intent);		} else {			Toast.makeText(activity, "您还没有安装新浪微博！", Toast.LENGTH_SHORT).show();		}	}}
    

易信好友：

public class ShareToYxFriend {	//易信好友	private static final String PackageName = "im.yixin";	private static final String ActivityName = "im.yixin.activity.share.ShareToSessionActivity";	//pics are OK。 text is not....	public static void share(Activity activity,String msg, ArrayList
    
      images) {		if (AppInstallHelper.isInstalled(activity, PackageName,				ActivityName)) {			ShareUtil shareUtil = new ShareUtil(activity, images);			Intent baseIntent = shareUtil.getBaseIntent(ActivityName);//			baseIntent.putExtra("summary", msg);//			baseIntent.putExtra(Intent.EXTRA_TITLE, msg);//			baseIntent.putExtra(Intent.EXTRA_TEXT, msg);			baseIntent.putExtra(Intent.EXTRA_SUBJECT, msg);			activity.startActivity(baseIntent);		} else {			Toast.makeText(activity, "您还没有安装易信！", Toast.LENGTH_SHORT).show();		}	}	}
    

易信状态：

public class ShareToYxZone {	private static final String PackageName = "im.yixin";	private static final String ActivityName = "im.yixin.activity.share.ShareToSnsActivity";	//pics are OK。 text is not....	public static void share(Activity activity,String msg, ArrayList
    
      images) {		if (AppInstallHelper.isInstalled(activity, PackageName,				ActivityName)) {			ShareUtil shareUtil = new ShareUtil(activity, images);			Intent baseIntent = shareUtil.getBaseIntent(ActivityName);			//			baseIntent.putExtra("summary", msg);//			baseIntent.putExtra(Intent.EXTRA_TITLE, msg);			baseIntent.putExtra(Intent.EXTRA_TEXT, msg);//			baseIntent.putExtra(Intent.EXTRA_SUBJECT, msg);			activity.startActivity(baseIntent);		} else {			Toast.makeText(activity, "您还没有安装易信！", Toast.LENGTH_SHORT).show();		}	}	}
