Android 调用startResolutionForResult时，onActivityResult（）未在片段中执行

当我调用以编程方式使用GoogleAppClient在片段中启用gps时出现问题。。。 我的代码是

 final Status status = result.getStatus();
                final LocationSettingsStates state = result.getLocationSettingsStates();
                switch (status.getStatusCode())
                {
                    case LocationSettingsStatusCodes.SUCCESS:
                        // All location settings are satisfied. The client can initialize location
                        // requests here.
                        getCurrentLocation();
                        break;
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the user
                        // a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            status.startResolutionForResult(getActivity(), REQUEST_ID_GPS_PERMISSIONS);
                        } catch (IntentSender.SendIntentException e) {
                            // Ignore the error.
                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        break;
                }

我的onActivityResult是

 final Status status = result.getStatus();
                final LocationSettingsStates state = result.getLocationSettingsStates();
                switch (status.getStatusCode())
                {
                    case LocationSettingsStatusCodes.SUCCESS:
                        // All location settings are satisfied. The client can initialize location
                        // requests here.
                        getCurrentLocation();
                        break;
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the user
                        // a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            status.startResolutionForResult(getActivity(), REQUEST_ID_GPS_PERMISSIONS);
                        } catch (IntentSender.SendIntentException e) {
                            // Ignore the error.
                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        break;
                }

但是我的onActicvityResult（）没有在片段中执行。 问题在哪里？？？

帮帮我…..提前谢谢。

我今天刚写完一些同样的代码。您需要实现

onActivityForResult（）

方法，但不幸的是

startResolutionForResult（）

没有调用片段；它回调包含片段的活动

您必须在调用活动中（或在管理片段的任何位置）实现onActivityResult（），然后将结果转发给片段

我在ActivitityResult上的activities中做了类似的操作（FragmentBase只是我用于所有其他片段的基类，请确保在添加片段时标记它们）：

---

请按照以下步骤操作：

一,。不活动：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        YourFragment fragment = (YourFragment ) getSupportFragmentManager().findFragmentByTag("TAG_NAME");
        if (fragment != null) {
            fragment .onActivityResult(requestCode, resultCode, data);
        }

    }

零碎

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 {
 // Now in fragment will triggger Here you can do work

}

---

因为片段被放置在活动中，它们的生命周期与包含活动的生命周期紧密耦合

1） 在活动中：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Fragment frg = getSupportFragmentManager().findFragmentById(R.id.fragment_container_main);
    if (frg != null) {
        frg.onActivityResult(requestCode, resultCode, data);
    }
}

现在，片段的容器活动将向片段提供意图数据、请求代码和结果，因此要获取数据并生成片段，您必须在片段中覆盖

onActivityResult（int-requestCode、int-resultCode、intent-data）

2） 零碎

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

}

---

在那里，您将收到来自父活动的回调。请执行任何您想发送或获取回调的操作。

2019年解决方案[Kotlin][AndroidX]

1。在您的片段中：

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    Log.d(context!!, "onActivityResult: [From Fragment]: " + requestCode + ", " + resultCode)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    Log.d(this, "onActivityResult: [From Activity]:  " + requestCode + ", " + resultCode)
    val navHostFragment = supportFragmentManager.fragments.first() as? NavHostFragment
    if(navHostFragment != null) {
        val childFragments = navHostFragment.childFragmentManager.fragments
        childFragments.forEach { fragment ->
            fragment.onActivityResult(requestCode, resultCode, data)
        }
    }
}

2。在您的活动中：

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    Log.d(context!!, "onActivityResult: [From Fragment]: " + requestCode + ", " + resultCode)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    Log.d(this, "onActivityResult: [From Activity]:  " + requestCode + ", " + resultCode)
    val navHostFragment = supportFragmentManager.fragments.first() as? NavHostFragment
    if(navHostFragment != null) {
        val childFragments = navHostFragment.childFragmentManager.fragments
        childFragments.forEach { fragment ->
            fragment.onActivityResult(requestCode, resultCode, data)
        }
    }
}

如果您使用的是Android导航组件，这将起作用

---

将这一行用于

片段

，以获得活动结果

onActivityResult

startIntentSenderForResult(status.getResolution().getIntentSender(), REQUEST_ID_GPS_PERMISSIONS, null, 0, 0, 0, null);

代替

 status.startResolutionForResult(getActivity(), REQUEST_ID_GPS_PERMISSIONS);

---

当您需要解析

状态

或

可解析API异常

时，我建议您利用

活动。registerForActivityResult

API代替

startResolutionForResult

：

val launcher = activity.registerForActivityResult(ActivityResultContracts.StartIntentSenderForResult()) { result ->
        if (result.resultCode == Activity.RESULT_OK) {
            // User accepted
        } else {
            // User didn't accepted
        }
    }

val intentSenderRequest = IntentSenderRequest.Builder(exception.resolution).build()
launcher.launch(intentSenderRequest)

---

在该片段的Activity类中创建一个onActivityResult，并在其中放置一个调试器，以检查是否以getActivity（）的形式启动活动。startActivityForResult（…）将其替换为startActivityForResult（…）；。已执行活动的onActivityResult，但当我从活动调用片段的任何函数时，上下文总是null@SubhechhuKhanal我不是在调用startActivityForResult，我是在调用startResolutionForResult。如果正在调用活动的onActivityResult（），您不能从onActivityResult（）调用片段的onActivityResult（）吗活动范围？？onActivityResult（请求代码、结果代码、数据）节省了我的时间。这是一个很好的答案，但最准确的答案是替换

status.startResolutionForResult（getActivity（），REQUEST\u ID\u GPS\u PERMISSIONS）this.startinentsenderforresult（status.getResolution（）.getIntentSender（），REQUEST\u ID\u GPS\u PERMISSIONS，null，0，0，null）的片段中的code>。这样，您就不必在活动中添加onActivityResult，您的片段就会得到结果directly@JoseJet明亮的如果你把你的答案写下来，我会投赞成票。@JoseJet这正是我想要的。非常感谢@你的评论救了我一天！谢谢。它就像一个符咒！谢谢你的例子！已经找了好几个小时了谢谢！我在中找到了你删除的答案。这是帮助我使用新API的唯一答案。您在@KonstantinKonopko？面临的问题是什么？它非常适合我well@NikunjParadva这只有在我将
onActivityResult
添加到片段和活动中时才有效
