안드로이드 매니페스트에서 자바 페이지를 찾을 수 없습니다

Question

안드로이드 스튜디오가 "LineDetails"라는 두 번째 자바 페이지를 찾지 못하는 이유가 궁금합니다. "CreateLine"이라는 첫 페이지를 사용할 수 있습니다. 왜 두 번째 페이지를 찾을 수 없습니까? 활동

<application android:label="@string/app_name" 
    android:icon="@mipmap/ic_launcher" 
    android:theme="@style/AppTheme"> 
    <activity 
     android:name=".CreateLine" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <activity 
     android:name=".LineDetails" 
     android:label="Line Details" > 
    </activity> 
</application> 

Answer 1

LineDetails입니까? 가있는 경우 예 활동 경로가 your.package.name.LineDetails 경우보다이

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    package="your.package.name"> 

    <activity 
     android:name=".LineDetails" 
     android:label="Line Details" >   
</manifest> 

같은 선언보다 경우 onther 패키지 이름보다이 경로 your.package.name.OtherName.LineDetails처럼 추가 한마디로

<activity 
     android:name=".OtherName.LineDetails" 
     android:label="Line Details" > 

당신은 패키지 이름이 매니페스트 태그에 선언 후 활동의 경로를 제공해야 package="your.package.name"

LineDetails가 조각 인 경우? 우리가 알다시피 우리는 자동으로 매니페스트 파일에 추가 활동의 기본 템플릿을 통해 작업을 만들 때마다 AndroidManifiest.xml이를 선언 할 필요 이상의안드로이드 스튜디오에서,

파일. 두 번째 activity onCreate() 메서드가 호출 될 때 모든 뷰가 올바르게 인스턴스화되었는지 검사합니다.
