我只需要通过推文分享一张图片。

这是我的代码

Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("image/*");
        if (mInsertableToGallery) {
            mInsertableToGallery = false;
            mInsertedImagePath = MediaStore.Images.Media.insertImage(getContentResolver(), mShareImage,
                    getResources().getString(R.string.app_name) + System.currentTimeMillis(), getResources().getString(R.string.app_name));
        }
        // share only 5 specific apps:
        List<Intent> targetedShareIntents = new ArrayList<>();
        List<ResolveInfo> resInfos = getPackageManager().queryIntentActivities(shareIntent, 0);
        if (!resInfos.isEmpty()) {
            for (ResolveInfo resolveInfo : resInfos) {
                String packageName = resolveInfo.activityInfo.packageName;
                Intent targetedShareIntent = new Intent(Intent.ACTION_SEND);
                targetedShareIntent.setType("image/*");
                targetedShareIntent.setPackage(packageName);
                targetedShareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(mInsertedImagePath));
                if (TextUtils.equals(packageName, "com.facebook.katana") //fb
                ||TextUtils.equals(packageName, "com.instagram.android") //instagram
                ||TextUtils.equals(packageName, "jp.naver.line.android") //line
                ||TextUtils.equals(packageName, "com.google.android.apps.plus") // plus
                ||TextUtils.equals(packageName, "com.twitter.android")) // twitter
            {
                targetedShareIntents.add(targetedShareIntent);
            }

            }
        }
        Intent chooser = Intent.createChooser(targetedShareIntents.remove(0), "");
        chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
        startActivity(chooser);

然后我得到了结果:

当点击“安卓系统”时，推特分享弹窗:

我想要的:

1. 如何仅通过推文或直接消息通过 Twitter 进行分享？

2. 如何更改共享项目的标题和图标。 Ex Twitter 分享项目从“Android 系统”到“Tweet”？

最佳答案

我无法将 Tweet 和私信都放在前面，但下面的代码可以让你找到其中之一。实际上你可以把两者都放在前面，但两者都以相同的名称“Tweet”出现，所以有点不可用。 我还包括了 facebook、insta 和 tumblr。 要使用直接消息代替推文，请将 com.twitter.android.composer.ComposerActivity 替换为 com.twitter.android.DMActivity。要获得两者，请为 DMActivity 添加另一个“if”。

不能确定，但​​我认为您不能为您的应用程序更改包的图标。

List<Intent> targetedShareIntents = new ArrayList<Intent>();
        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
        shareIntent.setType("image/jpeg");//("text/plain");
        Uri uri = Uri.fromFile(outFile);
        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
        List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(shareIntent, 0);
        for (ResolveInfo resolveInfo : resInfo) {
            String packageName = resolveInfo.activityInfo.packageName;
            Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
            targetedShareIntent.setType("image/jpeg");
            targetedShareIntent.putExtra(Intent.EXTRA_STREAM, uri);
            if(TextUtils.equals(packageName,"com.facebook.katana")|TextUtils.equals(packageName,"com.instagram.android")
                    |TextUtils.equals(packageName,"com.tumblr")) {
                targetedShareIntent.setPackage(packageName);
                targetedShareIntents.add(targetedShareIntent);
            }
            if(TextUtils.equals(resolveInfo.activityInfo.name,"com.twitter.android.composer.ComposerActivity")) {
                targetedShareIntent.setPackage(packageName);
                targetedShareIntent.setClassName(
                        resolveInfo.activityInfo.packageName,
                        resolveInfo.activityInfo.name);
                targetedShareIntents.add(targetedShareIntent);
            }
        }
        Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
        startActivity(chooserIntent);
