如何在android 6.0+中同时提出多个权限
我想要求用户同时接受以下权限（逐个），权限如下：checkLocationPermission，checkReadSMS，checkCallingPermission，checkReadState，checkContactWriteState。 那么，我如何在我的第一个屏幕本身中询问所有这些权限。 在这方面请帮帮我。 提前致谢。
您必须首先检查用户手机构建版本是否为23。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { askPermissions(true); } else { startActivity(new Intent(PermissionsActivity.this, SplashActivity.class)); finish(); } 如果版本是23，那么您需要询问权限。
private void askPermissions(boolean isForOpen) { isRationale = false; List permissionsRequired = new ArrayList(); final List permissionsList = new ArrayList (); if (!checkPermission(permissionsList, Manifest.permission.WRITE_EXTERNAL_STORAGE)) permissionsRequired.add("Write External Storage"); if (!checkPermission(permissionsList, Manifest.permission.CALL_PHONE)) permissionsRequired.add("Call phone"); if (!checkPermission(permissionsList, Manifest.permission.READ_PHONE_STATE)) permissionsRequired.add("Read phone state"); if (!checkPermission(permissionsList, Manifest.permission.READ_CONTACTS)) permissionsRequired.add("Read Contacts"); if (!checkPermission(permissionsList, Manifest.permission.RECEIVE_SMS)) permissionsRequired.add("Receive SMS"); if (!checkPermission(permissionsList, Manifest.permission.GET_ACCOUNTS)) permissionsRequired.add("Get Accounts"); if (!checkPermission(permissionsList, Manifest.permission.ACCESS_COARSE_LOCATION)) permissionsRequired.add("Location"); if (!checkPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION)) permissionsRequired.add("Location"); if (permissionsList.size() > 0 && !isRationale) { if (permissionsRequired.size() > 0) { } if (isForOpen) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { ActivityCompat.requestPermissions(this, permissionsList.toArray(new String[permissionsList.size()]), 11); } } } else if (isRationale) { if (isForOpen) { new android.support.v7.app.AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle) .setTitle("Permission Alert") .setMessage("You need to grant permissions manually. Go to permission and grant all permissions.") .setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); Uri uri = Uri.fromParts("package", getPackageName(), null); intent.setData(uri); startActivityForResult(intent, 123); } }) .show(); } } else { startActivity(new Intent(PermissionsActivity.this, SplashActivity.class)); finish(); } } private boolean checkPermission(List permissionsList, String permission) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) { permissionsList.add(permission); // Check for Rationale Option if (!isFirst) { if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) { isRationale = true; return false; } } } } return true; }
在onRequestPermissionsResult上，您需要检查授予的权限
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { switch (requestCode) { case 11: Map perms = new HashMap(); // Initial perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.CALL_PHONE, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.RECEIVE_SMS, 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.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.RECEIVE_SMS) == PackageManager.PERMISSION_GRANTED) { // All Permissions Granted startActivity(new Intent(PermissionsActivity.this, SplashActivity.class)); finish(); } else { // Permission Denied Toast.makeText(this, "Some Permission is Denied.", Toast.LENGTH_SHORT) .show(); isFirst = false; askPermissions(true); } break; default: super.onRequestPermissionsResult(requestCode, permissions, grantResults); } }
如果用户已将权限设置为永不再询问，则将打开应用程序设置屏幕。 用户将允许/拒绝那里的许可。 您需要再次检查activityResult。
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); askPermissions(true); }
if (!hasPermissions()){ // your app doesn't have permissions, ask for them. requestNecessaryPermissions(); } else { // your app already have permissions allowed. // do what you want. } private boolean hasPermissions() { int res = 0; // list all permissions which you want to check are granted or not. String[] permissions = new String[] {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; for (String perms : permissions){ res = checkCallingOrSelfPermission(perms); if (!(res == PackageManager.PERMISSION_GRANTED)){ // it return false because your app dosen't have permissions. return false; } } // it return true, your app has permissions. return true; } private void requestNecessaryPermissions() { // make array of permissions which you want to ask from user. String[] permissions = new String[] {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { // have arry for permissions to requestPermissions method. // and also send unique Request code. requestPermissions(permissions, REQUEST_CODE_STORAGE_PERMS); } } /* when user grant or deny permission then your app will check in onRequestPermissionsReqult about user's response. */ @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grandResults) { // this boolean will tell us that user granted permission or not. boolean allowed = true; switch (requestCode) { case REQUEST_CODE_STORAGE_PERMS: for (int res : grandResults) { // if user granted all required permissions then 'allowed' will return true. allowed = allowed && (res == PackageManager.PERMISSION_GRANTED); } break; default: // if user denied then 'allowed' return false. allowed = false; break; } if (allowed) { // if user granted permissions then do your work. dispatchTakePictureIntent(); } else { // else give any custom waring message. if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (shouldShowRequestPermissionRationale(Manifest.permission.CAMERA)) { Toast.makeText(MainActivity.this, "Camera Permissions denied", Toast.LENGTH_SHORT).show(); } else if (shouldShowRequestPermissionRationale(Manifest.permission.WRITE_EXTERNAL_STORAGE)){ Toast.makeText(MainActivity.this, "Storage Permissions denied", Toast.LENGTH_SHORT).show(); } } } }
