仅要求 Android Marshmallow 的运行时权限？

【中文标题】仅要求 Android Marshmallow 的运行时权限？

【问题描述】：

我只想为 marshmallow 添加运行时权限，因为它会使我的应用程序在 android marshmallow 设备中崩溃，否则它会正常工作。是否可以一次添加多个权限？我已经编写了相机权限的代码，但是

我已经为单一权限编写了代码，并且工作正常。

private  void  requestpermissioncamera()

final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_CAMERA)) permissionsNeeded.add("Camera");
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),PERMISSION_REQUEST_CODE);
return;

此功能用于检查天气许可是否被授予。

private boolean checkPermission()
int result = ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA);
if (result == PackageManager.PERMISSION_GRANTED)
return true;
 else 
return false;

【参考方案1】：

当然是。您可以在下面看到它是如何实现的示例：

public String[] PERMISSIONS_STORAGE = 
      Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE
  ;


public boolean verifyStoragePermissions(Activity activity, int REQUEST_EXTERNAL_STORAGE) 

    initialize(activity);

    // Check if we have write permission
    int permission =
        ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (permission != PackageManager.PERMISSION_GRANTED) 
      // We don't have permission so prompt the user
      ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE);
      return false;
     else 
      return true;
    
  

【参考方案2】：

对于我的项目，我使用这种方法制作了 Utils 类：

public static boolean checkAllAndRequestPermisions(Activity activity, int requestCode, LinkedList<String> permissionsList) 
       LinkedList<String> needPermissions = new LinkedList<>();
        for(String permission : permissionsList)
           if (ContextCompat.checkSelfPermission(activity, permission) != activity.getPackageManager().PERMISSION_GRANTED)
               needPermissions.add(permission);
           
        
        if (!needPermissions.isEmpty())
                ActivityCompat.requestPermissions(activity, needPermissions.toArray(new String[needPermissions.size()]), requestCode);
        
            return true;
    

并像这样实现 onRequestPermissinsResult 接口：

@Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) 
        switch (requestCode) 
            case Consts.SOME_PERMISSIONS_REQUEST_CODE: 
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) 

                 else 
                    Toast.makeText(getApplicationContext(), "Need permissions", Toast.LENGTH_LONG).show();
                
                return;
            
            // other 'case' lines to check for other
            // permissions this app might request
        
    

它不是完美的解决方案，但第一次可以，我希望它的帮助。

另外别忘了，你可以在 gradle targetSdkVersion 中设置小于 23 以有时间实现所有请求权限功能。

【参考方案3】：

一次获得多个权限很容易。

我希望下面的代码可以帮助您授予多个权限。

private  void  requestpermissioncamera()

    List<String> permissionsNeeded = new ArrayList<String>();

    final List<String> permissionsList = new ArrayList<String>();
    if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsNeeded.add("GPS");
    if (!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
permissionsNeeded.add("Read Contacts");
    if (!addPermission(permissionsList, Manifest.permission.WRITE_CONTACTS))
permissionsNeeded.add("Write Contacts");
    if(!addPermission(permissionsList,Manifest.permission.CAMERA))
permissionsNeeded.add("Camera");
    if(!addPermission(permissionsList, Manifest.permission.ACCESS_NOTIFICATION_POLICY))
permissionsNeeded.add("push Notification");

    if (permissionsList.size() > 0) 
        if (permissionsNeeded.size() > 0) 
        // Need Rationale
        String message = "You need to grant access to " + permissionsNeeded.get(0);
        for (int i = 1; i < permissionsNeeded.size(); i++)
        message = message + ", " + permissionsNeeded.get(i);
        showMessageOKCancel(message,new DialogInterface.OnClickListener() 
           @Override
           public void onClick(DialogInterface dialog, int which) 
               requestPermissions(permissionsList.toArray(new String[permissionsList.size()]), REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
                    
                );
           return;
      
      requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
      return;

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) 
    switch (requestCode) 
    case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
    
    Map<String, Integer> perms = new HashMap<String, Integer>();
    // Initial
    perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
    perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
    perms.put(Manifest.permission.WRITE_CONTACTS, PackageManager.PERMISSION_GRANTED);
    perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
    perms.put(Manifest.permission.ACCESS_NOTIFICATION_POLICY, PackageManager.PERMISSION_GRANTED);

    // Fill with results
    for (int i = 0; i < permissions.length; i++)
        perms.put(permissions[i], grantResults[i]);
    // Check for ACCESS_FINE_LOCATION
    if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.WRITE_CONTACTS) == PackageManager.PERMISSION_GRANTED) 
    
    // All Permissions Granted
    //    insertDummyContact();
     else 
    // Permission Denied
    Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
    .show();
    
    
    break;
    default:
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
