我想在单个请求中使用以下权限：
请不要改变原意，保留HTML标记。
ActivityCompat.requestPermissions(Activity activity,new String permisionList[],int permissionRequestcode);
但是我的问题是有时我只请求一个权限，我了解到组权限，但它只适用于由开发人员决定的相同组，比如CONTACT_GROUP: read_contact,write_contact等。
我想创建自定义组权限，它只需要一个请求，并且只提供一个响应。
谢谢
你可以在一个请求中同时询问多个权限（来自不同的组）。为此，您需要将所有权限添加到字符串数组中，并将其作为requestPermissions API的第一个参数提供，如下所示：
requestPermissions(new String[]{
Manifest.permission.READ_CONTACTS,
Manifest.permission.ACCESS_FINE_LOCATION},
ASK_MULTIPLE_PERMISSION_REQUEST_CODE);
这样做时，您将看到权限弹出窗口堆叠在一起。当然，您需要处理每个权限的接受和拒绝（包括“不再询问”）选项。同样的内容也已经在这里美妙地解释了。
this，否则它就无法工作 ActivityCompat.requestPermissions(this, new String[]{ Manifest.permission.WRITE_EXTERNAL_STORAGE, ...} ,ASK_MULTIPLE_PERMISSION_REQUEST_CODE); - Yonjuni首先初始化权限请求代码
public static final int PERMISSIONS_MULTIPLE_REQUEST = 123;
检查安卓版本
private void checkAndroidVersion() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkPermission();
} else {
// write your logic here
}
}
检查多个权限代码
private void checkPermission() {
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.READ_EXTERNAL_STORAGE) + ContextCompat
.checkSelfPermission(getActivity(),
Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale
(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE) ||
ActivityCompat.shouldShowRequestPermissionRationale
(getActivity(), Manifest.permission.CAMERA)) {
Snackbar.make(getActivity().findViewById(android.R.id.content),
"Please Grant Permissions to upload profile photo",
Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
new View.OnClickListener() {
@Override
public void onClick(View v) {
requestPermissions(
new String[]{Manifest.permission
.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
PERMISSIONS_MULTIPLE_REQUEST);
}
}).show();
} else {
requestPermissions(
new String[]{Manifest.permission
.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
PERMISSIONS_MULTIPLE_REQUEST);
}
} else {
// write your logic code if permission already granted
}
}
用户授权后回调方法
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case PERMISSIONS_MULTIPLE_REQUEST:
if (grantResults.length > 0) {
boolean cameraPermission = grantResults[1] == PackageManager.PERMISSION_GRANTED;
boolean readExternalFile = grantResults[0] == PackageManager.PERMISSION_GRANTED;
if(cameraPermission && readExternalFile)
{
// write your logic here
} else {
Snackbar.make(getActivity().findViewById(android.R.id.content),
"Please Grant Permissions to upload profile photo",
Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
new View.OnClickListener() {
@Override
public void onClick(View v) {
requestPermissions(
new String[]{Manifest.permission
.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
PERMISSIONS_MULTIPLE_REQUEST);
}
}).show();
}
}
break;
}
}
如果需要多个权限，您可以使用以下代码：
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
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();
}
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;
}
我这里有一个简单的解决方案，-(多个权限检查)
String[] permissions = new String[]{
Manifest.permission.WRITE_CALL_LOG,
Manifest.permission.READ_CALL_LOG,
Manifest.permission.READ_CONTACTS,
Manifest.permission.WRITE_CONTACTS}; // Here i used multiple permission check
if (checkPermissions()) { // permissions granted.
getCallDetails();
}
最后，复制以下代码
private boolean checkPermissions() {
int result;
List<String> listPermissionsNeeded = new ArrayList<>();
for (String p : permissions) {
result = ContextCompat.checkSelfPermission(getApplicationContext(), p);
if (result != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(p);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case MULTIPLE_PERMISSIONS: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { // permissions granted.
getCallDetails(); // Now you call here what ever you want :)
} else {
String perStr = "";
for (String per : permissions) {
perStr += "\n" + per;
} // permissions list of don't granted permission
}
return;
}
}
}
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) - ČamoMULTIPLE_PERMISSIONS 的值是多少？ - KernelPanic如前所述，目前每个权限组都有自己的权限对话框，必须分别调用。
您将为每个权限组拥有不同的对话框，但您可以在onRequestPermissionsResult()回调方法中一起检查结果。
public boolean checkForPermission(final String[] permissions, final int permRequestCode, int msgResourceId) {
final List<String> permissionsNeeded = new ArrayList<>();
for (int i = 0; i < permissions.length; i++) {
final String perm = permissions[i];
if (ContextCompat.checkSelfPermission(getActivity(), permissions[i]) != PackageManager.PERMISSION_GRANTED) {
if (shouldShowRequestPermissionRationale(permissions[i])) {
final AlertDialog dialog = AlertDialog.newInstance( getResources().getString(R.string.permission_title), getResources().getString(msgResourceId) );
dialog.setPositiveButton("OK", new View.OnClickListener() {
@Override
public void onClick(View view) {
// add the request.
permissionsNeeded.add(perm);
dialog.dismiss();
}
});
dialog.show( getActivity().getSupportFragmentManager(), "HCFAlertDialog" );
} else {
// add the request.
permissionsNeeded.add(perm);
}
}
}
if (permissionsNeeded.size() > 0) {
// go ahead and request permissions
requestPermissions(permissionsNeeded.toArray(new String[permissionsNeeded.size()]), permRequestCode);
return false;
} else {
// no permission need to be asked so all good...we have them all.
return true;
}
}
你可以像下面这样调用上述方法：
if ( checkForPermission( new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA}, REQUEST_PERMISSION_EXTERNAL_STORAGE_RESULT, R.string.permission_image) ) {
// DO YOUR STUFF
}
public void checkPermissions(){
if(ContextCompat.checkSelfPermission(getApplicationContext(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)== PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(getApplicationContext(),Manifest.permission.CAMERA)==PackageManager.PERMISSION_GRANTED){
//Do_SOme_Operation();
}else{
requestStoragePermission();
}
}
public void requestStoragePermission(){
ActivityCompat.requestPermissions(this
,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.CAMERA},1234);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode){
case 1234:if(grantResults[0]==PackageManager.PERMISSION_GRANTED && grantResults[1]==PackageManager.PERMISSION_GRANTED){
// Do_SOme_Operation();
}
default:super.onRequestPermissionsResult(requestCode,permissions,grantResults);
}
}
