Question

我正在寻找一种方式，如何使用android共享意图分享一个文本到社交网络。几乎每个人都提供此代码

Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, sometext);
startActivity(Intent.createChooser(shareIntent, "Share using"));

但它不适用于Facebook。有没有办法与所有网络共享文本。感谢。

Answer 1

您可以使用社交网络库直接发布到选定的社交网络，而无需任何代码混乱

我简单地使用ASNE它是真实的，不仅可以发帖，还可以登录或结交朋友

修改：正如@benka建议我添加一些代码，以便我在应用中向社交网络发帖：

为所选社交网络添加依赖关系（Facebook和Twitter，但ASNE包含更多）：

dependencies {
...
    compile 'com.github.asne:asne-facebook:0.2.1'
    compile 'com.github.asne:asne-twitter:0.2.1'
...
}

简单地从ASNE添加mSocialNetworkManager

mSocialNetworkManager = (SocialNetworkManager) getFragmentManager().findFragmentByTag(SOCIAL_NETWORK_TAG);
    if (mSocialNetworkManager == null) {
        mSocialNetworkManager = new SocialNetworkManager();
        FacebookSocialNetwork fbNetwork = new FacebookSocialNetwork(this, fbScope);
        mSocialNetworkManager.addSocialNetwork(fbNetwork);
        TwitterSocialNetwork twNetwork = new TwitterSocialNetwork(this, key, secret);
        mSocialNetworkManager.addSocialNetwork(twNetwork);
        getFragmentManager().beginTransaction().add(mSocialNetworkManager, SOCIAL_NETWORK_TAG).commit();
    }

显示按钮以在操作栏菜单中共享我的自定义按钮，最后检查登录并使用

socialNetwork.requestPostMessage("Message");

这就是全部，我需要获取好友列表，我只需添加

socialNetwork.requestGetFriends();

public void onShareClick(View v) {
    Resources resources = getResources();

    Intent emailIntent = new Intent();
    emailIntent.setAction(Intent.ACTION_SEND);
    // Native email client doesn't currently support HTML, but it doesn't hurt to try in case they fix it
    emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_native)));
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
    emailIntent.setType("message/rfc822");

    PackageManager pm = getPackageManager();
    Intent sendIntent = new Intent(Intent.ACTION_SEND);     
    sendIntent.setType("text/plain");


    Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));

    List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
    List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();        
    for (int i = 0; i < resInfo.size(); i++) {
        // Extract the label, append it, and repackage it in a LabeledIntent
        ResolveInfo ri = resInfo.get(i);
        String packageName = ri.activityInfo.packageName;
        if(packageName.contains("android.email")) {
            emailIntent.setPackage(packageName);
        } else if(packageName.contains("twitter") || packageName.contains("facebook") || packageName.contains("mms") || packageName.contains("android.gm")) {
            Intent intent = new Intent();
            intent.setComponent(new ComponentName(packageName, ri.activityInfo.name));
            intent.setAction(Intent.ACTION_SEND);
            intent.setType("text/plain");
            if(packageName.contains("twitter")) {
                intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_twitter));
            } else if(packageName.contains("facebook")) {
                // Warning: Facebook IGNORES our text. They say "These fields are intended for users to express themselves. Pre-filling these fields erodes the authenticity of the user voice."
                // One workaround is to use the Facebook SDK to post, but that doesn't allow the user to choose how they want to share. We can also make a custom landing page, and the link
                // will show the <meta content ="..."> text from that page with our link in Facebook.
                intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_facebook));
            } else if(packageName.contains("mms")) {
                intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_sms));
            } else if(packageName.contains("android.gm")) {
                intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_gmail)));
                intent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));               
                intent.setType("message/rfc822");
            }

            intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
        }
    }

    // convert intentList to array
    LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);

    openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
    startActivity(openInChooser);       
}
