Android在单个对话框中具有多个运行时权限
作者：互联网
我试图在一个对话框文件中获得所有许可,然后单击下面的链接为我提供了一个示例

这是我的代码
public class MActivity extends AppCompatActivity {
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_m);
insertDummyContactWrapper();
}
@TargetApi(Build.VERSION_CODES.M)
private void insertDummyContactWrapper() {
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 (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;
}
insertDummyContact();
}
@TargetApi(Build.VERSION_CODES.M)
private boolean addPermission(List<String> permissionsList, String permission) {
if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
if (!shouldShowRequestPermissionRationale(permission))
return false;
}
return true;
}
private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(MActivity.this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", null)
.create()
.show();
}
private static final String TAG = "Contacts";
private void insertDummyContact() {
// Two operations are needed to insert a new contact.
ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(2);
// First, set up a new raw contact.
ContentProviderOperation.Builder op =
ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
.withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)
.withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null);
operations.add(op.build());
// Next, set the name for the contact.
op = ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
.withValue(ContactsContract.Data.MIMETYPE,
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,
"__DUMMY CONTACT from runtime permissions sample");
operations.add(op.build());
// Apply the operations.
ContentResolver resolver = getContentResolver();
try {
resolver.applyBatch(ContactsContract.AUTHORITY, operations);
} catch (RemoteException e) {
Log.d(TAG, "Could not add a new contact: " + e.getMessage());
} catch (OperationApplicationException e) {
Log.d(TAG, "Could not add a new contact: " + e.getMessage());
}
}
@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);
// 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(MActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
.show();
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
}
我得到了询问许可的对话框,在确定后,我检查了设置-> apps-> myappname->许可,但未设置许可？
有人能在这件事上帮助我吗？
解决方法:
当我在mainfest文件中添加权限时,它可以很好地工作.
注意：但是我还是改了
public class RecursionActivity extends AppCompatActivity {
Context context;
private static final int PERMISSION_REQUEST_CODE = 1;
String p1 = android.Manifest.permission.READ_CONTACTS, p2 = android.Manifest.permission.ACCESS_FINE_LOCATION,
p3 = android.Manifest.permission.WRITE_CONTACTS, p4 = Manifest.permission.CAMERA;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this;
setContentView(R.layout.activity_recursion);
permissionAccess();
}
private void permissionAccess() {
if (!checkPermission(p1)) {
Log.e("TAG",p1);
requestPermission(p1);
} else if (!checkPermission(p2)) {
Log.e("TAG",p2);
requestPermission(p2);
} else if (!checkPermission(p3)) {
Log.e("TAG",p3);
requestPermission(p3);
} else if (!checkPermission(p4)) {
Log.e("TAG",p4);
requestPermission(p4);
} else {
Toast.makeText(context, "All permission granted", Toast.LENGTH_LONG).show();
}
}
private boolean checkPermission(String permission) {
int result = ContextCompat.checkSelfPermission(context, permission);
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
private void requestPermission(String permission) {
if (ContextCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(RecursionActivity.this, new String[]{permission}, PERMISSION_REQUEST_CODE);
} else {
//Do the stuff that requires permission...
Log.e("TAG","Not say request");
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
Log.e("TAG", "val " + grantResults[0]);
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
permissionAccess();
} else {
Toast.makeText(context, "Bye bye", Toast.LENGTH_LONG).show();
}
break;
}
}
}
我不知道这是否是一个优化的解决方案,但我希望它对某人有帮助.
