Question

我想在所有可能的应用中分享图片和标题，包括facebook。我尝试了此代码，它适用于除facebook以外的所有其他应用。有人可以帮助我如何与facebook中的图像共享标题。

    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
    shareIntent.putExtra(Intent.EXTRA_TEXT, caption);
    shareIntent.setType("image/*");
    mcontext.startActivity(Intent.createChooser(shareIntent, "Share Image"));

Answer 1

试试这个。

将您的图片存储在外部存储目录中并获取该图片的路径并使用android.content.Intent.EXTRA_TEXT文本并传递静态文本。

String fileName = "imagename.jpg";//Name of an image
String externalStorageDirectory = Environment.getExternalStorageDirectory().toString();
String myDir = externalStorageDirectory + "/saved_images/"; // the file will be in saved_images
Uri uri = Uri.parse("file:///" + myDir + fileName);
Intent intentShare = new Intent(android.content.Intent.ACTION_SEND);
intentShare.setType("text/plain");
intentShare.putExtra(android.content.Intent.EXTRA_SUBJECT, "Testing Subject");
intentShare.putExtra(android.content.Intent.EXTRA_TEXT, "Testing Texts");
intentShare.putExtra(Intent.EXTRA_STREAM, uri);


PackageManager pm = v.getContext().getPackageManager();
   List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
     for (final ResolveInfo app : activityList) 
     {
         if ((app.activityInfo.name).startsWith("com.facebook.katana")) 
         {
           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);
          v.getContext().startActivity(shareIntent);
          break;
        }
      }

在清单中包含此权限。

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

public void onShareClick(View v){
    List<Intent> targetShareIntents=new ArrayList<Intent>();
    Intent shareIntent=new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    List<ResolveInfo> resInfos=getPackageManager().queryIntentActivities(shareIntent, 0);
    if(!resInfos.isEmpty()){
        for(ResolveInfo resInfo : resInfos){
            String packageName=resInfo.activityInfo.packageName;
            Log.i("Package Name", packageName);
            if(packageName.contains("com.twitter.android") || packageName.contains("com.facebook.katana") ){
                Intent intent=new Intent();
                intent.setComponent(new ComponentName(packageName, resInfo.activityInfo.name));
                intent.setAction(Intent.ACTION_SEND);
                intent.setType("text/plain");
                intent.putExtra(Intent.EXTRA_TEXT, "Text");
                intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                intent.setPackage(packageName);
                targetShareIntents.add(intent);
            }
        }
        if(!targetShareIntents.isEmpty()){
            Intent chooserIntent=Intent.createChooser(targetShareIntents.remove(0), "Choose app to share");
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetShareIntents.toArray(new Parcelable[]{}));
            startActivity(chooserIntent);
        }else{
            showDialaog(this);
        }
    }
}

与Facebook中的图像共享描述不起作用
