我一直在寻找一种解决方案来隐藏DatePicker中的以下任何一个微调器.对于Android 5.0,内部变量已更改,在我的情况下,在我的设备更新后,日和月旋转器再次可见.

Android 4.4和Kitkat解决方案

DatePicker dpDate = (DatePicker) findViewById(R.id.dpDate);

    // Initialize Date Picker
    int year    = dpDate.getYear();
    int month   = dpDate.getMonth();
    int day     = dpDate.getDayOfMonth();
    dpDate.init(year, month, day, this);

Field f[] = dpDate.getClass().getDeclaredFields();
            for (Field field : f) 
            {
                // Hides the DAY spinner
                if(field.getName().equals("mDayPicker") || field.getName().equals("mDaySpinner")) 
                {
                    field.setAccessible(true);
                    Object dayPicker = new Object();
                    dayPicker = field.get(dpDate);
                    ((View) dayPicker).setVisibility(View.GONE);
                }

                // Hides the MONTH spinner
                if(field.getName().equals("mMonthPicker") || field.getName().equals("mMonthSpinner")) 
                {
                    field.setAccessible(true);
                    Object monthPicker = new Object();
                    monthPicker = field.get(dpDate);
                    ((View) monthPicker).setVisibility(View.GONE); …

我在Android Studio 3.0 Canary 9中遇到了几个错误.这些错误是"无法解决:"android包,下面列出了一些.我刚安装了SDK的所有额外软件包,但我仍然遇到了一个gradle构建错误:

Error:(82, 13) Failed to resolve: com.android.support:multidex:1.0.2
Error:(85, 13) Failed to resolve: com.android.support:support-v13:26.0.0
Error:(89, 13) Failed to resolve: com.android.support:recyclerview-v7:26.0.0
Error:(97, 24) Failed to resolve: com.android.support.test:runner:1.0.0

以及一些与测试和支持库有关的软件包.

这是我的构建脚本:

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha9'
        classpath 'com.google.gms:google-services:3.1.0'
        classpath 'com.google.firebase:firebase-plugins:1.1.1'
    }
}

我真的不确定为什么这不能建立.我刚刚更新了所有的软件包,所有的支持库在26.0.0 - >都是一样的compileSdkVersion 26

非常感谢您的任何建议!

[编辑] - 这是我的gradle构建日志

提前感谢您的帮助.我无法找到关于我在项目中收到的此错误的帖子.

我有时只收到这个错误,但我不确定它为什么会出现,因为它似乎是随机的.在我的数据输入中,我没有注意到任何异常.

我的android应用程序正在尝试建立与远程服务器的连接并将数据推送到PostgreSQL表中.是否有人能够向我推荐此错误的正确文档或解释其含义.我很感激你的帮助.

这是我的代码:
