Question

我正在开发一个应用程序，我想在运行时请求多个权限。我的代码适用于一个权限。但是，当我想要求多个权限时，我的代码什么都不做。谁能告诉我我的代码有什么问题？

感谢任何形式的帮助。

Answer 1

这样做...... 在on create

 int PERMISSION_ALL = 1;
    String[] PERMISSIONS = {Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE};
    if(!hasPermissions(this, PERMISSIONS)){
        //ask user for granting permissions on api22+
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }

检查是否已获得许可...

public static boolean hasPermissions(Context context, String... permissions) {
    //checaking if the application has permission
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

这是相机和读取存储，你可以添加你想要的任何东西......

多重教授：

public abstract class AbsRuntimePermission extends Activity {

private SparseIntArray mErrorString;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mErrorString = new SparseIntArray();

}

public abstract void onPermissionsGranted(int requestCode);

public void requestAppPermissions(final String[]requestedPermissions, final int stringId, final int requestCode) {
    mErrorString.put(requestCode, stringId);

    int permissionCheck = PackageManager.PERMISSION_GRANTED;
    boolean showRequestPermissions = false;
    for(String permission: requestedPermissions) {
        permissionCheck = permissionCheck + ContextCompat.checkSelfPermission(this, permission);
        showRequestPermissions = showRequestPermissions || ActivityCompat.shouldShowRequestPermissionRationale(this, permission);
    }

    if (permissionCheck!=PackageManager.PERMISSION_GRANTED) {
        if(showRequestPermissions) {
            Snackbar.make(findViewById(android.R.id.content), stringId, Snackbar.LENGTH_INDEFINITE).setAction("GRANT", new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ActivityCompat.requestPermissions(AbsRuntimePermission.this, requestedPermissions, requestCode);
                }
            }).show();
        } else {
            ActivityCompat.requestPermissions(this, requestedPermissions, requestCode);
        }
    } else {
        onPermissionsGranted(requestCode);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    int permissionCheck = PackageManager.PERMISSION_GRANTED;
    for(int permisson : grantResults) {
        permissionCheck = permissionCheck + permisson;
    }

    if( (grantResults.length > 0) && PackageManager.PERMISSION_GRANTED == permissionCheck) {
        onPermissionsGranted(requestCode);
    } else {
        //Display message when contain some Dangerous permisson not accept

        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light_Dialog));
        alertDialogBuilder
                .setMessage("Please enble permisions")
                .setTitle("Please enble permisions")
                .setCancelable(false)
                .setPositiveButton(" Enable",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                Intent i = new Intent();
                                i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                                i.setData(Uri.parse("package:" + getPackageName()));
                                i.addCategory(Intent.CATEGORY_DEFAULT);
                                i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                                i.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
                                i.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
                                startActivity(i);

                            }
                        });



                        alertDialogBuilder.setNegativeButton(" Cancel ", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                dialog.cancel();
                            }
                        });

        AlertDialog alert = alertDialogBuilder.create();
        alert.show();

    }

            }

    }

并在您的主要活动中：

public class MainActivity extends AbsRuntimePermission {

private static final int REQUEST_PERMISSION = 10;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    requestAppPermissions(new String[]{
            Manifest.permission.READ_CONTACTS,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_CONTACTS},
            R.string.msg,REQUEST_PERMISSION);
}

@Override
public void onPermissionsGranted(int requestCode) {
    //Do anything when permisson granted
    Toast.makeText(getApplicationContext(), "Permission granted", Toast.LENGTH_LONG).show();
}
}

Answer 3

已经授予了首次检查权限。

您可以在这里查看多个权限。

if (checkForPermission(getActivity(), CAMERA_PERMISSION) && checkForPermission(getActivity(), GALLERY_PERMISSION)) {
      //Permission granted here
      //TODO

    } else {
        requestPermissions(new String[]{CAMERA_PERMISSION, GALLERY_PERMISSION}, 1);
}

checkForPermission方法。

/***
 * Method is checking permission for Marshmallow
 *
 * @param context
 * @param permission
 * @return
 */
private static boolean checkForPermission(final Context context, String permission) {
    int result = ContextCompat.checkSelfPermission(context, permission);
    //If permission is granted then it returns 0 as result
    if (result == PackageManager.PERMISSION_GRANTED) {
        return true;
    } else {
        return false;
    }
}

onRequestPermissionsResult方法与onActivityResult类似。

/***
 * This is call when user allow or deny permissions in the Marshmallow
 *
 * @param requestCode
 * @param permissions
 * @param grantResults
 */
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case 1:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
               //Permission granted here
               //TODO

            }
            break;
    }
}

Answer 4

试试这个：

final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;

public boolean checkMultiplePermission() {
    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;
}


 private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
    new AlertDialog.Builder(MainActivity.this)
            .setMessage(message)
            .setPositiveButton("OK", okListener)
            .setNegativeButton("Cancel", null)
            .create()
            .show();
}

当每个权限获得其授权结果时，结果将被发送到相同的回调方法onRequestPermissionsResult()

 @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
                //do your task..
            } else {
                // Permission Denied
                Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
                        .show();
            }
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

希望这有助于你..

Answer 5

你可以通过这种方式实现这一目标

    private static final int MY_PERMISSIONS_REQUEST_CALL = 7;
    private static String[] PERMISSIONS = {
        Manifest.permission.CALL_PHONE, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};

现在创建一个方法

 public void checkSmsPermission() {
    try {
        if (Build.VERSION.SDK_INT >= 23) {
            if (ActivityCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED
                    || ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED ||
                    ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE)
                            != PackageManager.PERMISSION_GRANTED

                    ) {
                requestPermission();
            } else
                checkLogin();
        } else {
            checkLogin();


        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}



you can check grants result array for checking which permission is granted



  @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    try {
        boolean flagDenied = false;
        switch (requestCode) {
            case MY_PERMISSIONS_REQUEST_CALL:


                if (grantResults.length > 0
                        ) {
                    for (int i : grantResults)
                        if (i == -1) {
                            flagDenied = true;
                            break;
                        }
                    if (!flagDenied)
                        doJob();
                    else showPermissionDialog();
                }


                break;


        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Answer 6

我的代码可以正常使用一个权限。但是，当我想问对于多个权限，我的代码什么都不做。

除了你的代码太冗长并且难以阅读之外，checkMultiplePermission()方法工作正常。我已将其复制到测试项目中，当我启动应用程序时，我被要求获得5个权限。

（5因为WRITE_EXTERNAL_STORAGE / READ_EXTERNAL_STORAGE和ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION合并为一个权限请求

请仔细检查您是否使用新权限更新了AndroidManifest.xml文件。可能是以前当您使用一个权限测试代码时，您已接受它，然后更多权限被添加到请求逻辑但忘记列在AndroidManifest.xml中。在这种情况下，Android将忽略您的请求，也不会抛出异常，它将无所事事。

在activity：

中

private static final int MY_PERMISSIONS = 111;

onCreate方法中的

：

String[] mPermissionToRequest = new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.CAMERA,Manifest.permission.CALL_PHONE};

ActivityCompat.requestPermissions(this, mPermissionsToRequest, MY_PERMISSIONS);

@Override

public void onRequestPermissionsResult( int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

}

检查您的AndroidManifest.xml文件：

<uses-permission android:name="android.permission.CALL_PHONE" />

<uses-permission android:name="android.permission.CAMERA" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

在Android Marshmallow中要求多个权限时遇到麻烦
