Android 6.0多重权限 [英] Android 6.0 multiple permissions

问题描述

我知道Android 6.0有新的权限，我知道我可以用这样的东西来调用它们

I know that Android 6.0 has new permissions and I know I can call them with something like this

if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
    PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this,
        new String[] { 
            Manifest.permission.WRITE_EXTERNAL_STORAGE
        }, PERMISSION_WRITE_STORAGE);
}

今天我看到一款需要3个权限的Google应用：联系人，短信和相机。它正在制作第1-3页并同时将它们全部调用以激活。

Today I saw a Google app which needs 3 permissions: contacts, sms and camera. It's making a page 1-3 and calls them all together at the same time to activate.

任何人都可以告诉我如何在同一时间调用4个权限来激活像短信，相机，联系人和存储？

Can anybody tell me how I can call 4 permissions to activate at the same time like sms, camera, contacts and storage?

示例（忘记谷歌应用程序的名称:(）

该应用程序需要短信，联系人和相机

Example (forgot the name of the google app :( )
The app needs sms,contacts and camera

应用程序问我（并进行了对话框1-3）激活短信，激活联系人然后是相机。
所以这个谷歌应用程序正在呼叫所有3所需的权限在一起，我的问题是我怎么能得到相同的？

the app asked me (and made a dialog page1-3) activate sms, activate contacts and then camera. So this google app was calling all 3 required permissions together and my question is how can i achive the same ?

推荐答案

只需在<$ c $中包含所有4个权限c> ActivityCompat.requestPermissions（...）调用和Android会像你提到的一样自动将它们一起分页。

Just include all 4 permissions in the ActivityCompat.requestPermissions(...) call and Android will automatically page them together like you mentioned.

我有一个帮助方法检查多个权限，看看是否有任何权限。

I have a helper method to check multiple permissions and see if any of them are not granted.

public static boolean hasPermissions(Context context, String... permissions) {
    if (context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

然后只需发送所有权限即可。 Android将仅询问它所需的那些。

Then just send it all of the permissions. Android will ask only for the ones it needs.

// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1; 
String[] PERMISSIONS = {
  android.Manifest.permission.READ_CONTACTS, 
  android.Manifest.permission.WRITE_CONTACTS, 
  android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
  android.Manifest.permission.READ_SMS, 
  android.Manifest.permission.CAMERA
};

if(!hasPermissions(this, PERMISSIONS)){
    ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
