Android 6.0 多权限

Android 6.0 multiple permissions(Android 6.0 多权限)

问题描述

我知道 Android 6.0 有新的权限，我知道我可以用类似这样的方式调用它们

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);
}

今天我看到一个需要 3 个权限的 Google 应用:联系人、短信和相机.它正在制作一个页面 1-3 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.

谁能告诉我如何调用 4 个权限同时激活，比如短信、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(忘记了 google 应用的名称:( )
该应用需要短信、联系人和相机

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

应用程序询问我(并在第 1-3 页创建了一个对话框)激活短信、激活联系人和相机.所以这个谷歌应用程序将所有 3 个必需的权限一起调用，我的问题是我怎样才能获得相同的权限?

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 ActivityCompat.requestPermissions(...) 调用中包含所有 4 个权限，Android 就会像您提到的那样自动将它们分页在一起.

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

我有一个辅助方法来检查多个权限，看看是否有任何一个没有被授予.

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;
}

或者在 Kotlin 中:

Or in Kotlin:

fun hasPermissions(context: Context, vararg permissions: String): Boolean = permissions.all {
    ActivityCompat.checkSelfPermission(context, it) == PackageManager.PERMISSION_GRANTED
}

然后将所有权限发送给它.Android 只会询问它需要的那些.

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);
}
