如何从android微调器中获取文本？

Question

我正在创建一个android微调器。它显示正常，但在选择选项时没有任何反应。为什么＆＃39;如果＆＃39;命令不起作用？

    //Error messages
    $messages = [
        "name.required" => "Name is required",
        "name.string" => "Name must be a string",
        "username.required" => "Username is required",
        "username.min" => "Username must be at least 6 characters",
        "email.required" => "Email is required",
        "email.email" => "Email is not valid"
    ];

    // validate the form data
    $validator = Validator::make($request->all(), [
            'name' => 'required|string',
            'username' => 'required|min:6',
            'email' => 'required|email'
        ], $messages);

    if ($validator->fails()) {
        return back()->withErrors($validator)->withInput();
    } else {
        //Some code here
    }

您没有意图启动活动。这样做：

        startActivity(intent);

在if和else中进行意图声明和赋值。
