我需要更改操作栏选项卡文本颜色.所以操作栏选项卡文本颜色显示为黑色.但我需要将其更改为白色.

我收到一个错误: android.view.InflateException: Couldn't resolve menu item onClick handler onClickEnterData in class com.android.timesheet.NewProjects.

我在菜单项中使用了onClick操作.我在NewProjects.java中提到了错误行

在Android Studio for Windows上导入之前在Mac OS X或Linux上设置的项目时,gradle build会产生错误:

-->Error:(12, 0) CreateProcess error=2, The system cannot find the file specified

要么

Error:(12, 0) A problem occurred evaluating project ':app'.
> Cannot run program "git" (in directory "<project path>"): CreateProcess error=2, The system cannot find the file specified`

的build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.1'
    }
}

def project
def  var

//Error line pointing out below line 

var = project.ext.gitHash = "git rev-parse --short HEAD".execute().text.trim() var --> Error:(12,0)

apply …

json结构:

{
  "Employee": [
       {"id":1,"name":"Dan" },
       {"id":2,"name":"Stack" },
       .....
    ]
}

app.component.ts:

 ngOnInit() {
 console.log("first", "Test");

    this.globalReader.getObjectData()
      .subscribe(data => this.getData = JSON.stringify(data),  ---> Response printed successfully here.I'm able to print it in label.
       error => alert(error),
       () => console.log("finished")

      );      

  }

编辑:

零件:

  <label text ="{{getData }}" ></label>



  getObjectData() {

    return this._http.get('/page/emp.json')
      .map((response :Response) => response.json());

  }  

之后,我不知道如何解析json并在listview中为此结构打印它.我提到了一些视频和杂货申请.但我仍然无法得到结果.我非常困惑arrayname员工.

我需要name在listview中只打印from响应.

在这些项目中，屏幕方向横向视图根本不起作用。

在android中，manifest我android:screen orientation=lanscape使用或不使用屏幕方向。你可以在清单中检查它。但不幸的是我没有得到输出。
