Java 仅为Android棉花糖请求运行时许可？

我只想为marshmallow添加运行时权限，因为它会使我在Android marshmallow设备中的应用程序崩溃，否则它会正常工作。是否可以一次添加多个权限？我已经为相机许可写了代码，但是

我已经为单一权限编写了代码，这很好

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;
}

一次获取多个权限很容易

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);
}

private void requestpermissioncamera（）
{
List permissions need=new ArrayList（）；
最终列表权限列表=新的ArrayList（）；
if（！addPermission（permissionsList，Manifest.permission.ACCESS\u FINE\u LOCATION））
所需许可。添加（“GPS”）；
如果（！addPermission（permissionsList，Manifest.permission.READ_CONTACTS））
需要许可。添加（“读取联系人”）；
if（！addPermission（permissionsList，Manifest.permission.WRITE_CONTACTS））
需要许可。添加（“写联系人”）；
if（！addPermission（permissionsList，Manifest.permission.CAMERA））
需要许可。添加（“摄像机”）；
if（！addPermission（permissionsList、Manifest.permission.ACCESS\u NOTIFICATION\u POLICY））
所需权限添加（“推送通知”）；
如果（permissionsList.size（）>0）{
如果（PermissionsNeed.size（）>0）{
//需要理由
String message=“您需要授予对”+权限need.get（0）的访问权限；
对于（inti=1；i

当然可以。下面是一个如何实现的示例：

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;
    }
  }

对于我的项目，我使用以下方法创建了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;
    }

这不是完美的解决方案，但第一次还行，我希望它能有所帮助

另外，别忘了，您可以将gradle targetSdkVersion设置为小于23，以便有时间实现所有请求权限功能

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;
    }

@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
        }
    }
