根据他们选择分享的方法对Android Share Intent extras进行分支

Question

只想分享动态文本字符串+应用程序的URL.原生的Android共享意图设置正确,并且与Twitter,Gmail等完美配合.但是,正如许多人猜测的那样,它不适用于Facebook.显然因为Facebook不接受该intent.EXTRA_TEXT领域的文字,只有一个网址.

好吧,我对你们的问题是:有没有办法根据他们选择分享的方法来分支共享意图？例如,如果他们通过Gmail或Twitter共享,请使用现有的String + URL(所需选项)EXTRA_TEXT,但如果他们选择通过Facebook共享,则只使用URL作为EXTRA_TEXT.

并不是真的想要实现Facebook Android SDK来完成Android内置的简单任务.

感谢您的时间和建议.

试过这样的事情,但它显然失败了,因为它只检查共享选项是否存在(当共享弹出时,而不是在他们点击共享方法之后),它在选择方法时没有响应.

  String shareBody = "app string text " + act_txt + " more text! Get the app at http://www.appurl.com";

 PackageManager pm = view.getContext().getPackageManager();
    List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent, 0);
    for(final ResolveInfo app : activityList) {
         Log.i(TAG, "app.actinfo.name: " + app.activityInfo.name);
        //if((app.activityInfo.name).contains("facebook")) {
              if("com.facebook.katana.ShareLinkActivity".equals(app.activityInfo.name)) {


            sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://www.appurl.com");
            startActivity(Intent.createChooser(sharingIntent, "Share idea"));
            break;
        } else {
            sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "app name");
            sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
            startActivity(Intent.createChooser(sharingIntent, "Share"));
            break;
        }
    }

我在这里发布的原始问题很接近.在可能的shareIntent List的周期内,您需要创建针对特定共享选择的新共享意图(如facebook或twitter)

这是一个最终工作解决方案,如果选择了facebook,则只共享一个URL,否则共享完整的文本字符串+ url:

public void shareIt(View view){
    //sharing implementation
    List<Intent> targetedShareIntents = new ArrayList<Intent>();
    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    String shareBody = "string of text " + txt_var + " more text! Get the app at http://someapp.com";

    PackageManager pm = view.getContext().getPackageManager();
    List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent, 0);
    for(final ResolveInfo app : activityList) {

         String packageName = app.activityInfo.packageName;
         Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
         targetedShareIntent.setType("text/plain");
         targetedShareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "share");
         if(TextUtils.equals(packageName, "com.facebook.katana")){
             targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://someurl.com");
         } else {
             targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
         }

         targetedShareIntent.setPackage(packageName);
         targetedShareIntents.add(targetedShareIntent);

    }

    Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Share Idea");

    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
    startActivity(chooserIntent);

}
