Question

我使用以下代码从我的应用选择器中排除Facebook应用：

 List<Intent> targetedShareIntents = new ArrayList<Intent>();
    Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    intent.setType("image/*");
    List<ResolveInfo> resInfo = getActivity().getPackageManager().queryIntentActivities(intent, 0);
    if (!resInfo.isEmpty()) {
        for (ResolveInfo resolveInfo : resInfo) {
            String packageName = resolveInfo.activityInfo.packageName;
            Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
            targetedShareIntent.setType("image/*");
            targetedShareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "tooter.nl");
            if (!TextUtils.equals(packageName, "com.facebook.katana")) {


                targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT, st);
                targetedShareIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
                targetedShareIntent.setPackage(packageName);
                targetedShareIntents.add(targetedShareIntent);
            }

        }
        Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[targetedShareIntents.size()]));
        startActivity(chooserIntent);
    }

我使用该代码时删除了Facebook应用。但令人遗憾的是，甚至Twitter应用程序也被从应用程序选择器和其他不必要的应用程序中移除，例如＆＃34; Android系统＆＃34;在选择器上列出。我该怎么办？这段代码有缺失或错误吗？

检查下面的答案。它将仅排除Facebook应用程序的共享。

 void shareOnOtherSocialMedia() {

    List<Intent> shareIntentsLists = new ArrayList<Intent>();
    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("image/*");
    List<ResolveInfo> resInfos = getPackageManager().queryIntentActivities(shareIntent, 0);
    if (!resInfos.isEmpty()) {
      for (ResolveInfo resInfo : resInfos) {
        String packageName = resInfo.activityInfo.packageName;
        if (!packageName.toLowerCase().contains("facebook")) {
          Intent intent = new Intent();
          intent.setComponent(new ComponentName(packageName, resInfo.activityInfo.name));
          intent.setAction(Intent.ACTION_SEND);
          intent.setType("image/*");
          intent.setPackage(packageName);
          shareIntentsLists.add(intent);
        }
      }
      if (!shareIntentsLists.isEmpty()) {
        Intent chooserIntent = Intent.createChooser(shareIntentsLists.remove(0), "Choose app to share");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, shareIntentsLists.toArray(new Parcelable[]{}));
        startActivity(chooserIntent);
      } else
        Log.e("Error", "No Apps can perform your task");

    }
  }
}

并在任何地方调用上述功能。让我知道查询。

对于Android API 24及更高版本，您可以使用此：

val components = arrayOf(ComponentName(applicationContext, YourActivity::class.java))
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) 
   startActivity(Intent.createChooser(intent, null).putExtra(Intent.EXTRA_EXCLUDE_COMPONENTS,components))

对于其他情况，您可以拥有我写过的this solution（这使您可以排除一个条件

这是一个更通用的解决方案，能够为所有Android版本选择要排除的内容：

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val targetIntent = Intent(Intent.ACTION_SEND)
        targetIntent.type = "text/plain"
        targetIntent.putExtra(Intent.EXTRA_SUBJECT, "subject")
        targetIntent.putExtra(Intent.EXTRA_TEXT, "text")
        val excludedAppsPackageNames = hashSetOf( "com.pushbullet.android","com.android.bluetooth","com.google.android.apps.docs","com.google.android.gm")
        getIntentChooser(this, targetIntent, "choose!", object : ComponentNameFilter {
            override fun shouldBeFilteredOut(componentName: ComponentName): Boolean = excludedAppsPackageNames.contains(componentName.packageName)
        })?.let { startActivity(it) }
    }

    interface ComponentNameFilter {
        fun shouldBeFilteredOut(componentName: ComponentName): Boolean
    }

    private fun getIntentChooser(context: Context, intent: Intent, chooserTitle: CharSequence? = null, filter: ComponentNameFilter): Intent? {
        val resolveInfos = context.packageManager.queryIntentActivities(intent, 0)
//        Log.d("AppLog", "found apps to handle the intent:")
        val excludedComponentNames = HashSet<ComponentName>()
        resolveInfos.forEach {
            val activityInfo = it.activityInfo
            val componentName = ComponentName(activityInfo.packageName, activityInfo.name)
//            Log.d("AppLog", "componentName:$componentName")
            if (filter.shouldBeFilteredOut(componentName))
                excludedComponentNames.add(componentName)
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return Intent.createChooser(intent, chooserTitle).putExtra(Intent.EXTRA_EXCLUDE_COMPONENTS, excludedComponentNames.toTypedArray())
        }
        if (resolveInfos.isNotEmpty()) {
            val targetIntents: MutableList<Intent> = ArrayList()
            for (resolveInfo in resolveInfos) {
                val activityInfo = resolveInfo.activityInfo
                if (excludedComponentNames.contains(ComponentName(activityInfo.packageName, activityInfo.name)))
                    continue
                val targetIntent = Intent(intent)
                targetIntent.setPackage(activityInfo.packageName)
                targetIntent.component = ComponentName(activityInfo.packageName, activityInfo.name)
                // wrap with LabeledIntent to show correct name and icon
                val labeledIntent = LabeledIntent(targetIntent, activityInfo.packageName, resolveInfo.labelRes, resolveInfo.icon)
                // add filtered intent to a list
                targetIntents.add(labeledIntent)
            }
            val chooserIntent: Intent?
            // deal with M list seperate problem
            chooserIntent = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                // create chooser with empty intent in M could fix the empty cells problem
                Intent.createChooser(Intent(), chooserTitle)
            } else {
                // create chooser with one target intent below M
                Intent.createChooser(targetIntents.removeAt(0), chooserTitle)
            }
            if (chooserIntent == null) {
                return null
            }
            // add initial intents
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetIntents.toTypedArray<Parcelable>())
            return chooserIntent
        }
        return null
    }
}

Answer 3

Android N（API 24）引入了黑名单Intent.EXTRA_EXCLUDE_COMPONENTS，它比白名单Intent.EXTRA_INITIAL_INTENTS更好，更简单。

Answer 4

根据Ragu Swaminathan的答案更新了Kotlin答案

fun share() {

        val shareIntent = Intent()
        shareIntent.action = Intent.ACTION_SEND
        shareIntent.type = "text/plain"
        val resInfoList = activity?.packageManager?.queryIntentActivities(shareIntent, 0)

        val shareIntentList = arrayListOf<Intent>()

        if (resInfoList?.isNotEmpty() == true) {
            for (resInfo in resInfoList) {
                val packageName = resInfo.activityInfo.packageName
                if (!packageName.toLowerCase().contains("discord")) {
                    val intent = Intent()
                    intent.component = ComponentName(packageName, resInfo.activityInfo.name)
                    intent.action = Intent.ACTION_SEND
                    intent.type = "text/plain"
                    intent.`package` = packageName
                    intent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.")
                    shareIntentList.add(intent)
                }
            }
        }

        if (shareIntentList.isEmpty()) {
            Toast.makeText(activity, "No apps to share!", Toast.LENGTH_LONG).show()
        } else {
            val chooserIntent = Intent.createChooser(Intent(), "Choose app to share")
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, shareIntentList.toTypedArray())
            activity?.startActivity(chooserIntent)
        }
    }

Answer 5

感谢Ragu Swaminathan的回答，它可以完美地排除IntentChooser中的特定应用程序。但是，因为'shareIntentLists'被添加到'chooserIntent'前面，所以如果list的大小不是4的倍数，则可能会出现一些空格。要解决此问题，请尝试：

Intent chooserIntent = Intent.createChooser(new Intent(), "Choose app to share");

Answer 6

我不得不排除Facebook应用程序，因为它们使用Intent#EXTRA_EXCLUDE_COMPONENTS破坏了共享意图（关于用户原创性），

        Intent intent = new Intent(Intent.ACTION_SEND);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            intent.setTypeAndNormalize("text/plain");
        } else {
            intent.setType("text/plain");
        }
        intent.putExtra(Intent.EXTRA_TEXT, "Text to share");

        Intent chooser = Intent.createChooser(intent, "Share Text");

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

            ArrayList<ComponentName> targets = new ArrayList<>();

            // remove facebook which has a broken share intent
            for (ResolveInfo candidate : requireActivity().getPackageManager().queryIntentActivities(intent, 0)) {
                String packageName = candidate.activityInfo.packageName;
                if (packageName.toLowerCase().contains("facebook")) {
                    targets.add(new ComponentName(packageName, candidate.activityInfo.name));
                }
            }
            chooser.putExtra(Intent.EXTRA_EXCLUDE_COMPONENTS, targets.toArray(new ComponentName[0]));
        }

        startActivity(chooser);

这仅适用于android N及以上版本

如何从ACTION_SEND意图中排除特定的应用程序？
