我试图让导航抽屉在工具栏下面打开.

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer_layout"
tools:context=".MainActivity">
<RelativeLayout
    android:layout_width = "match_parent"
    android:layout_height = "wrap_content">
    <include layout="@layout/toolbar"
        android:id="@+id/toolbar"/>
    <FrameLayout
        android:layout_below="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/background_color"/>
</RelativeLayout>
<ListView
    android:id="@+id/drawer"
    android:layout_width="260dp"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar"
    android:layout_marginTop="56dp"
    android:layout_gravity="start">
</ListView>
</android.support.v4.widget.DrawerLayout>

如何重新格式化xml以便导航栏在工具栏下方打开？

我正在尝试使用新Android设计库中的CoordinatorLayout.我把包裹加到了gradle; 然后我尝试使用布局我得到这个错误:

我期待在特定时间删除文档.

const TestSchema = new Schema({
 expire_at: {
 type: Date,
 },
}, {
 timestamps: true,
});
TestSchema.index({expire_at: 1}, {expireAfterSeconds: 0});

POST

const test = new TestSchema(this.request.body);
  test.expire_at = test.end_time;

  try {
    yield test.save();
  } catch (error) {
    this.status = 409;
    this.response.body = error.errors;
    return;
  }

  this.response.body = test;
  this.status = 201;

似乎文件在expire_at中指定的时间删除.

我使用的是这种日期格式:2016-07-20T05:01:19.567Z

我目前有一个使用Firebase进行用户身份验证和存储数据的移动应用程序。

我想从Firebase迁移到AWS。从Firebase导出数据库非常简单。下载JSON导出并填充AWS。

如何将用户身份验证迁移到Cognito？

我需要在用户登录时启动我的Mac应用程序.

这就是我做的:

我创建了一个新的Coca Application Target.

•构建设置将"跳过安装"设置为"是"

•Info.plist"应用程序仅后台"到"是"

•在主应用程序和帮助程序应用程序上启用了沙盒.

•将复制文件阶段添加到主应用程序:Wrapper,Contents/Library/LoginItems,添加了Helper.app

Helper应用程序的AppDelegate.swift

import Cocoa
import ServiceManagement
extension Notification.Name {
    static let killLauncher = Notification.Name("killLauncher")
}

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

    @objc func terminate() {
        NSApp.terminate(nil)
    }

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        print("hi")
        let mainAppIdentifier = "co.myprogress.osx"
        let runningApps = NSWorkspace.shared.runningApplications
        let isRunning = !runningApps.filter { $0.bundleIdentifier == mainAppIdentifier }.isEmpty

        if !isRunning {
            DistributedNotificationCenter.default().addObserver(self,
                                                                selector: #selector(self.terminate),
                                                                name: .killLauncher,
                                                                object: mainAppIdentifier)

            let path = Bundle.main.bundlePath as NSString
            var components = path.pathComponents
            components.removeLast()
            components.removeLast() …

是否有一个常量值可以添加到工具栏颜色的十六进制代码中,以获得状态栏颜色？

我一直在Android工作室中使用默认抽屉,但它在操作栏中附带了两个对象,这些对象一直让我的用户烦恼,我无法弄清楚如何删除:示例操作和设置.

抽屉碎片:

/**
* Fragment used for managing interactions for and presentation of a navigation drawer.
* See the <a href="https://developer.android.com/design/patterns/navigation-drawer.html#Interaction">
* design guidelines</a> for a complete explanation of the behaviors implemented here.
*/
public class TroopNavigationDrawerFragment extends Fragment {

/**
 * Remember the position of the selected item.
 */
private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";

/**
 * Per the design guidelines, you should show the drawer on launch until the user manually
 * expands it. This shared preference …

我正在学习汇编，我创建了一个简单的退出程序。

.section __DATA, __data
.section __TEXT, __text
.globl _main

_main:
  movl $0x2000001, %eax   #System call exit, offset by 0x00000
  movl $1, %ebx           #Exit Return code
  syscall                 #Wakes up kernal to run the systen call

运行文件后如何回显 $？返回 0

组装和链接命令：

as exit.asm -o exit.o
ld exit.o -e _main -o exit
./exit
