仅针对Android Marshmallow请求运行时权限？

我想为marshmallow添加运行时权限，因为它会在Android marshmallow设备中崩溃我的应用程序，否则它会正常工作。 是否可以一次添加多个权限？ 我已经为相机许可编写了代码，但是

我已经编写了单一权限的代码，并且工作正常。

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

此function用于检查是否授予天气许可。

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

一次攻击很容易获得多个权限。

我希望下面的代码可以帮助您授予多个权限。

 private void requestpermissioncamera() { List permissionsNeeded = new ArrayList(); final List permissionsList = new ArrayList(); 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 perms = new HashMap(); // 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); }

当然如此。 您可以在下面看到如何实现它的示例：

 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; } } 

Answer 3

对于我的项目，我用这种方法制作了Utils类：

 public static boolean checkAllAndRequestPermisions(Activity activity, int requestCode, LinkedList permissionsList) { LinkedList 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; } 

并实现onRequestPermissinsResult接口，如下所示：

 @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，但第一次确定，我希望它的帮助。

另外不要忘记，你可以设置gradle targetSdkVersion少于23，以便有时间实现所有请求权限function。
