儘管將庫添加爲依賴項，Android Studio仍然無法檢測到我的庫組件

Question

我已經創建了一個簡單的項目，其中創建了一個名爲'mylibrary'的新模塊，其中包含一個Custom視圖。

庫在創建時自動添加到項目中的依賴關係列表中。

但是，依賴於此庫的應用程序無法找到庫中存在的自定義視圖。

我嘗試了幾個建議here，here和here，但他們都沒有工作。

我列出下面將所需的文件： -

的build.gradle（模塊：在MyLibrary）

apply plugin: 'com.android.library' 

android { 
    compileSdkVersion 24 
    buildToolsVersion "24.0.1" 

    defaultConfig { 
     minSdkVersion 16 
     targetSdkVersion 24 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile 'com.android.support:appcompat-v7:24.+' 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
} 

的build.gradle（項目：TESTAPP）

// 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:2.1.2' 

     // 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 
} 

build.gradle（Module：app）

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "24.0.1" 

    defaultConfig { 
     applicationId "app.auro.self.testapp" 
     minSdkVersion 16 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile project(':mylibrary') 
} 

settings.gradle（項目設置）

include ':app', ':mylibrary' 

在MyLibrary - > samplelayout.xml

<?xml version="1.0" encoding="utf-8"?> 
<merge xmlns:android="http://schemas.android.com/apk/res/android"> 

    <EditText 
     android:layout_width="200dp" 
     android:layout_height="wrap_content" 
     android:id="@+id/editText" 
     android:hint="HEY" 
     android:gravity="center" 
     android:layout_gravity="center_horizontal"/> 
</merge> 

在MyLibrary - > CustomView.java

package app.auro.self.mylibrary; 

import android.content.Context; 
import android.util.AttributeSet; 
import android.view.LayoutInflater; 
import android.widget.EditText; 
import android.widget.LinearLayout; 

import java.security.PrivateKey; 

/** 
* Created by stpl on 25/8/16. 
*/ 
public class CustomView extends LinearLayout { 

    private EditText editText; 

    public CustomView(Context context) { 
     this(context,null); 
    } 

    public CustomView(Context context, AttributeSet attrs) { 
     this(context, attrs,0); 
    } 

    public CustomView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 

     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     inflater.inflate(R.layout.samplelayout,this,true); 

     editText = (EditText) findViewById(R.id.editText); 
     editText.setText("HELLO"); 
    } 
} 

應用程序 - > activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context="app.auro.self.testapp.MainActivity"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <Cus //DOESN'T EVEN DETECT 

    </LinearLayout> 

</RelativeLayout> 

應用程序 - > MainActivity.java

package app.auro.self.testapp; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

import app.auro.self.mylibrary.CustomView; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     CustomView customView; 
    } 
}

在你的佈局XML文件中，只有android.widget包中的類可以直接與他們的名字一起使用。其他的一切都需要用完全合格的類名來聲明。對於如：

<!-- Won't work --> 
<CardView.../> 

<!-- Should work --> 
<android.support.v7.widget.CardView.../>
