如何在Facebook上分享文字和图片,我正在编写一个教会应用程序,我希望允许用户与URL共享文本和图像。

我可以分享在线应用链接,但无法分享文字&图像,我在哪里?

我的代码如下:

Button btnFbSharing = (Button) findViewById(R.id.fbSharing);
        btnFbSharing.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                 Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
                 shareIntent.setType("text/plain");
                 shareIntent.putExtra(android.content.Intent.EXTRA_TITLE, "Church Application");
                 shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "https://play.google.com/store/apps/details?id=com.facebook.katana");
                 shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "A new world begin");

                 shareIntent.putExtra(android.content.Intent.EXTRA_STREAM, R.drawable.ic_launcher);
                 PackageManager pm = getApplicationContext().getPackageManager();
                 List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
                 for (final ResolveInfo app : activityList) {
                    if ((app.activityInfo.name).contains("facebook")) {
                        final ActivityInfo activity = app.activityInfo;
                        final ComponentName name = new ComponentName(
                                    activity.applicationInfo.packageName,
                                    activity.name);
                        shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
                        shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
                                            | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
                        shareIntent.setComponent(name);
                        startActivity(shareIntent);
                       }
                 }                  
            }
        });

通过意图选择器在android中使用此共享网址 ... 你不直接在Facebook wallpost上分享任何文字

b2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String urlToShare = "www.google.com";
                Intent intent = new Intent(Intent.ACTION_SEND);
                intent.setType("text/plain");
                // intent.putExtra(Intent.EXTRA_SUBJECT, "Foo bar"); // NB:
                // has no effect!
                intent.putExtra(Intent.EXTRA_TEXT, urlToShare);

                // See if official Facebook app is found
                boolean facebookAppFound = false;
                List<ResolveInfo> matches = getPackageManager()
                        .queryIntentActivities(intent, 0);
                for (ResolveInfo info : matches) {
                    if (info.activityInfo.packageName.toLowerCase()
                            .startsWith("com.facebook.katana")) {
                        intent.setPackage(info.activityInfo.packageName);
                        facebookAppFound = true;
                        break;
                    }
                }

                // As fallback, launch sharer.php in a browser
                if (!facebookAppFound) {
                    String sharerUrl = "https://www.facebook.com/sharer/sharer.php?u="
                            + urlToShare;
                    intent = new Intent(Intent.ACTION_VIEW, Uri
                            .parse(sharerUrl));
                }

                startActivity(intent);
            }
        });

嘿,当我问同样的question

时,我做了很多研究

基本上,使用软件包名称“com.facebook.katana”无法从facebook应用程序中进行操作,因为它会在图像显示时忽略额外文本,但实际上bug会看到此文件,但在图像时可以有链接不在这里。我知道很烦人。

经过大量的关注后,我使用facebook sdk 3.14.1创建了我自己的活动,它允许图像和文本在这里是演示项目的github link给它一个去,让我们知道它是否有助于你
