下面是我的代码，我称此代码为获取运行时权限。在这种情况下，“shouldshowrequestpermissionrationale 始终返回 false”。我找不到解决方案为什么会这样。因此，不会显示运行时权限警报。请给我建议一个解决方案...

   private void checkRuntimePermission() {

    Logger.infoLog("checkRuntimePermission");
    if(ActivityCompat.checkSelfPermission(this, permissionsRequired[0]) != PackageManager.PERMISSION_GRANTED){
        Logger.infoLog("checkRuntimePermission first if");
        if(ActivityCompat.shouldShowRequestPermissionRationale(WelcomeActivity.this,permissionsRequired[0])){
            Logger.infoLog("checkRuntimePermission if");
            //just request the permission
            //Show Information about why you need the permission
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Need Multiple Permissions");

                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                    ActivityCompat.requestPermissions(WelcomeActivity.this,permissionsRequired,PERMISSION_CALLBACK_CONSTANT);
                }
            });
            builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            });
            builder.show();
        }else{
