如何针对ACTION_SEND意图过滤特定应用(并为每个应用设置不同的文字)

Question

在使用ACTION_SEND意图时,如何过滤掉特定应用？ 这个问题已经以各种方式提出,但我无法根据给出的答案收集解决方案.希望有人可以提供帮助.我想提供在应用程序内共享的功能.根据Android Dev Alexander Lucas的建议,我更倾向于使用意图并且不使用Facebook/Twitter API.

使用ACTION_SEND意图共享非常好,但问题是(1)我不希望每个共享选项,我宁愿将其限制为FB,Twitter和电子邮件,以及(2)我不想分享每个共享应用程序都是一样的.例如,在我的推特分享中,我将包括一些提及和主题标签限制为140或更少,而Facebook分享将包括链接和功能图像.

是否可以限制ACTION_SEND(共享)意图的选项？我已经看到了使用PackageManager和queryIntentActivities的一些事情,但是却无法弄清楚PackageManager和ACTION_SEND意图之间的联系.

要么

如果我可以使用ACTION_SEND意图直接进入Facebook或Twitter而不是弹出对话框,而不是过滤共享应用程序,我的问题也可以解决.如果是这种情况,那么我可以创建自己的对话框,当他们点击"Facebook"创建一个特定于Facebook的意图,然后将它们一直发送到Facebook.与Twitter相同.

或者是不可能的？Facebook和Twitter API是唯一的方式吗？

据我所知,StackOverflow有很多人以各种方式提出这个问题,但没有人完全回答它.

我的规范要求用​​户能够选择电子邮件,推特,脸书或短信,并为每个人选择自定义文本.以下是我完成的方法:

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")) { // If Gmail shows up twice, try removing this else-if clause and the reference to "android.gm" above
                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);       
}

我在各个地方找到了如何做到这一点,但我还没有在其他地方看到过所有这些.

请注意,此方法还隐藏了我不想要的所有愚蠢选项,例如通过wifi和蓝牙共享.

希望这有助于某人.

编辑: 在评论中,我被要求解释这段代码在做什么.基本上,它只ACTION_SEND为本机电子邮件客户端创建一个意图,然后在选择器上添加其他意图.制作特定于电子邮件的原始意图摆脱了所有额外的垃圾,如wifi和蓝牙,然后我从普通ACTION_SEND的纯文本类型获取我想要的其他意图,并在显示选择器之前加上它们.

当我抓住其他意图时,我为每个意图设置了自定义文本.

编辑2:我发布这篇文章已经有一段时间了,情况有所改变.如果您在选项列表中看到两次gmail,请尝试删除下面@h_k评论中建议的"android.gm"的特殊处理.

由于这个答案是几乎所有stackoverflow信誉点的来源,我必须至少尝试使其保持最新.

Answer 2

如果您想要一个自定义选项,那么您不应该依赖android为此操作提供的默认对话框.

你需要做的是推出自己的.您将需要查询PackageManager上哪些包处理您需要的操作,然后根据回复,您应用过滤和自定义文本.

具体而言,看看该方法queryIntentActivities所述的PackageManager类.您构建了将启动默认对话框(ACTION_SEND intent)的intent,将其传递给此方法,您将收到一个对象列表,其中包含有关可以处理该intent的活动的信息.使用它,您可以选择您想要的.

构建要显示的包列表后,需要构建自己的列表对话框(最好是具有对话框主题的活动),该对话框将显示该列表.

需要注意的一点是,很难使自定义对话框看起来像默认对话框.问题是该对话框中使用的主题是内部主题,您的应用程序无法使用.您可以尝试将其设置为与您想要的本机类似,或者进行完全自定义的外观(许多应用程序都像画廊应用程序那样)

Answer 3

研究发现,对我的作品寻找一个解决方案在这里(见第一个答案的第三点意见).此代码查找有效的Twitter客户端并使用它来发布推文.注意:它不会向您提供与各种Twitter客户端的Intent并允许您选择.

使用twitter分享:

Intent shareIntent = findTwitterClient(); 
shareIntent.putExtra(Intent.EXTRA_TEXT, "test");
startActivity(Intent.createChooser(shareIntent, "Share"));

调用此方法:

public Intent findTwitterClient() {
    final String[] twitterApps = {
            // package // name - nb installs (thousands)
            "com.twitter.android", // official - 10 000
            "com.twidroid", // twidroid - 5 000
            "com.handmark.tweetcaster", // Tweecaster - 5 000
            "com.thedeck.android" }; // TweetDeck - 5 000 };
    Intent tweetIntent = new Intent();
    tweetIntent.setType("text/plain");
    final PackageManager packageManager = getPackageManager();
    List<ResolveInfo> list = packageManager.queryIntentActivities(
            tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);

    for (int i = 0; i < twitterApps.length; i++) {
        for (ResolveInfo resolveInfo : list) {
            String p = resolveInfo.activityInfo.packageName;
            if (p != null && p.startsWith(twitterApps[i])) {
                tweetIntent.setPackage(p);
                return tweetIntent;
            }
        }
    }

    return null;
}

Facebook将使用" com.facebook.katana " 类似,但您仍然无法设置消息文本(2011年7月已弃用).

试试这个只分享三个应用程序 - Facebook,Twitter,KakaoStory.

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()){
        System.out.println("Have package");
        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") || packageName.contains("com.kakao.story")){
                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()){
            System.out.println("Have Intent");
            Intent chooserIntent=Intent.createChooser(targetShareIntents.remove(0), "Choose app to share");
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetShareIntents.toArray(new Parcelable[]{}));
            startActivity(chooserIntent);
        }else{
            System.out.println("Do not Have Intent");
            showDialaog(this);
        }
    }
}

此解决方案在ListView对话框中显示类似于选择器的应用程序列表:

由您来决定:

1. 获取相关应用程序包的列表
2. 给定包名称,调用相关意图

适配器类:

import java.util.List;

import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.graphics.drawable.Drawable;
import android.util.TypedValue;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class ChooserArrayAdapter extends ArrayAdapter<String> {
    PackageManager mPm;
    int mTextViewResourceId;
    List<String> mPackages;

    public ChooserArrayAdapter(Context context, int resource, int textViewResourceId, List<String> packages) {
        super(context, resource, textViewResourceId, packages);
        mPm = context.getPackageManager();
        mTextViewResourceId = textViewResourceId;
        mPackages = packages;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        String pkg = mPackages.get(position);
        View view = super.getView(position, convertView, parent);

        try {
            ApplicationInfo ai = mPm.getApplicationInfo(pkg, 0);

            CharSequence appName = mPm.getApplicationLabel(ai);
            Drawable appIcon = mPm.getApplicationIcon(pkg);

            TextView textView = (TextView) view.findViewById(mTextViewResourceId);
            textView.setText(appName);
            textView.setCompoundDrawablesWithIntrinsicBounds(appIcon, null, null, null);
            textView.setCompoundDrawablePadding((int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 12, getContext().getResources().getDisplayMetrics()));
        } catch (NameNotFoundException e) {
            e.printStackTrace();
        }

        return view;
    }

}

及其用法:

    void doXxxButton() {
        final List<String> packages = ...;
        if (packages.size() > 1) {
            ArrayAdapter<String> adapter = new ChooserArrayAdapter(MyActivity.this, android.R.layout.select_dialog_item, android.R.id.text1, packages);

            new AlertDialog.Builder(MyActivity.this)
            .setTitle(R.string.app_list_title)
            .setAdapter(adapter, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int item ) {
                    invokeApplication(packages.get(item));
                }
            })
            .show();
        } else if (packages.size() == 1) {
            invokeApplication(packages.get(0));
        }
    }

    void invokeApplication(String packageName) {
        // given a package name, create an intent and fill it with data
        ...
        startActivityForResult(intent, rq);
    }

您可以尝试下面的代码,它完美地工作.

在这里,我们分享一些特定的应用程序,即Facebook,Messenger,Twitter,Google Plus和Gmail.

public void shareIntentSpecificApps() {
        List<Intent> intentShareList = new ArrayList<Intent>();
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(shareIntent, 0);

        for (ResolveInfo resInfo : resolveInfoList) {
            String packageName = resInfo.activityInfo.packageName;
            String name = resInfo.activityInfo.name;
            Log.d(TAG, "Package Name : " + packageName);
            Log.d(TAG, "Name : " + name);

            if (packageName.contains("com.facebook") ||
                    packageName.contains("com.twitter.android") ||
                    packageName.contains("com.google.android.apps.plus") ||
                    packageName.contains("com.google.android.gm")) {

                if (name.contains("com.twitter.android.DMActivity")) {
                    continue;
                }

                Intent intent = new Intent();
                intent.setComponent(new ComponentName(packageName, name));
                intent.setAction(Intent.ACTION_SEND);
                intent.setType("text/plain");
                intent.putExtra(Intent.EXTRA_SUBJECT, "Your Subject");
                intent.putExtra(Intent.EXTRA_TEXT, "Your Content");
                intentShareList.add(intent);
            }
        }

        if (intentShareList.isEmpty()) {
            Toast.makeText(MainActivity.this, "No apps to share !", Toast.LENGTH_SHORT).show();
        } else {
            Intent chooserIntent = Intent.createChooser(intentShareList.remove(0), "Share via");
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentShareList.toArray(new Parcelable[]{}));
            startActivity(chooserIntent);
        }
    }

感谢@dacoinminster.我对他的答案进行了一些修改,包括热门应用程序的包名称和这些应用程序的排序.

List<Intent> targetShareIntents = new ArrayList<Intent>();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
PackageManager pm = getActivity().getPackageManager();
List<ResolveInfo> resInfos = pm.queryIntentActivities(shareIntent, 0);
if (!resInfos.isEmpty()) {
    System.out.println("Have package");
    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")
                || packageName.contains("com.whatsapp") || packageName.contains("com.google.android.apps.plus")
