在将我的类完全剥离出来之后，它仍然不起作用，我意识到这个活动是使用tabhost示例化的。
当我停止使用tabhost时，将成功显示提示。我猜新的权限提示不支持tabhosts-这是一个bug吗？
与应用程序请求相同的问题没有出现
我最终创建了一个permissionsrequestactivity，它代表我的tabhost处理权限请求和响应，然后退出（通过intent extras bundle传入请求的权限信息）。
它将请求的响应作为广播传回，由我的tabhost接收。
有点黑客，但工作正常！

检查您是否已经在android的manifest文件中添加了请求的权限，就像在android m之前一样，只有这样您才能获得预期的行为。
将权限添加到清单中，以便您可以通过activitycompat.requestpermissions请求权限：

<uses-permission android:name="android.permission. ACCESS_FINE_LOCATION" />

我将分享对我有用的代码。在活动的protectedvoidoncreate（bundle savedinstancestate）{}方法中，我希望看到提示，其中包含以下代码：

/* Check whether the app has the ACCESS_FINE_LOCATION permission and whether the app op that corresponds to
     * this permission is allowed. The return value is an int: The permission check result which is either
     * PERMISSION_GRANTED or PERMISSION_DENIED or PERMISSION_DENIED_APP_OP.
     * Source: https://developer.android.com/reference/android/support/v4/content/PermissionChecker.html
     * While testing, the return value is -1 when the "Your location" permission for the App is OFF, and 1 when it is ON.
     */
    int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
    // The "Your location" permission for the App is OFF.
    if (permissionCheck == -1){
        /* This message will appear: "Allow [Name of my App] to access this device's location?"
         * "[Name of my Activity]._instance" is the activity.
         */
        ActivityCompat.requestPermissions([Name of my Activity]._instance, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_ACCESS_FINE_LOCATION);
    }else{
        // The "Your location" permission for the App is ON.
        if (permissionCheck == 0){
        }
    }

在protectedvoid oncreate（bundle savedinstancestate）{}方法之前，我创建了以下常量和方法：

public static final int REQUEST_CODE_ACCESS_FINE_LOCATION = 1; // For implementation of permission requests for Android 6.0 with API Level 23.

// Code from "Handle the permissions request response" at https://developer.android.com/training/permissions/requesting.html.
@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ACCESS_FINE_LOCATION: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // location-related task you need to do.                

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

我在一个使用tabhost的项目中也遇到过同样的问题。基于@robin解决方案，我使用eventbus库从子活动向tabactity发送消息。
事件总线：https://github.com/greenrobot/eventbus
创建事件对象：

public class MessageEvent {
    private String message;
    public MessageEvent(String message){
        this.message = message;
    }

    public String getMessage(){
        return this.message;
    }
}

在您的主要活动中：

private EventBus eventBus = EventBus.getDefault();
@Override
protected void onCreate(Bundle savedInstanceState) {
    eventBus.register(this);
}
@Override
protected void onDestroy() {
    eventBus.unregister(this);
    super.onDestroy();
}
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(MessageEvent event) {
    if (event.getMessage().equals("contacts")){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && checkSelfPermission(android.Manifest.permission.WRITE_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(MainPage.this,new String[]{android.Manifest.permission.WRITE_CONTACTS}, 100 );
        }
    }
};

为要请求的权限设置其他消息。在您的儿童活动中，您可以发布适当的信息：

EventBus.getDefault().post(new MessageEvent("contacts"));

注意onrequestpermissionsresult回调和请求代码；）！它只在主要活动中起作用。
