片段不工作在android工作室

-1

我写了这段代码在android activity_main.xml中的。但它给出了一个错误，它不能识别片段。片段不工作在android工作室

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.bignerdranch.android.stockapp.MainActivity" 
    android:padding="16dp"> 

    <TextureView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:text="hello world"/> 
    <fragment 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 

     android:layout_weight="1"/> 
    <Button 
     android:id="@+id/search_button" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:onClick="onClick" 
     android:text="button"/> 

</RelativeLayout>

它是依赖关系问题吗？我怎么能解决它？我都很感谢你的建议！

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.1' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
}

错误

你可以分享你gradle这个依赖 –

发表您的全logcat的错误.. – rafsanahmad007

什么是堆栈跟踪？ –

添加您的片段类名片段标签的属性。见下面

 <fragment 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:name="com.myapp.fragments.MyFragment" 
    />

希望这个作品
