android - 在Android棉花糖中询问多个权限时遇到问题

我正在开发一个想要在运行时请求多个权限的应用程序。
我的代码对于一个许可来说运行良好。但是，当我想请求多个权限时，我的代码什么也没做。
谁能告诉我我的代码有什么问题吗？

对于多个权限:

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();

    }

            }

    }

在您的主要 Activity 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();
}
}
