ViewPagerを使ったTabLayoutがアプリのクラッシュにつながる

Question

私は別の部分にTabLayoutを持っているアンドロイドアプリのGUIを作っています。今、私のMainActivity.java Uptilとこのようになりactivity_main.xml：

MainActivity.java：

package com.example.cortana.testing.activity; 

import android.support.design.widget.TabLayout; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentPagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.support.v7.widget.Toolbar; 

import java.util.ArrayList; 
import java.util.List; 

import com.example.cortana.testing.R; 


import com.example.cortana.testing.fragments.Fragment_A; 
import com.example.cortana.testing.fragments.Fragment_B; 




public class MainActivity extends AppCompatActivity { 

    private Toolbar toolbar; 
    private TabLayout tabLayout; 
    private ViewPager viewPager; 

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

     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

     viewPager = (ViewPager) findViewById(R.id.viewpager); 
     setupViewPager(viewPager); 

     tabLayout = (TabLayout) findViewById(R.id.tabs); 
     tabLayout.setupWithViewPager(viewPager); 
    } 

    private void setupViewPager(ViewPager viewPager) { 
     ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); 
     adapter.addFragment(new Fragment_A(), "A"); 
     adapter.addFragment(new Fragment_B(), "B"); 
     viewPager.setAdapter(adapter); 
    } 

    class ViewPagerAdapter extends FragmentPagerAdapter { 
     private final List<Fragment> mFragmentList = new ArrayList<>(); 
     private final List<String> mFragmentTitleList = new ArrayList<>(); 

     public ViewPagerAdapter(FragmentManager manager) { 
      super(manager); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return mFragmentList.get(position); 
     } 

     @Override 
     public int getCount() { 
      return mFragmentList.size(); 
     } 

     public void addFragment(Fragment fragment, String title) { 
      mFragmentList.add(fragment); 
      mFragmentTitleList.add(title); 
     } 

     @Override 
     public CharSequence getPageTitle(int position) { 
      return mFragmentTitleList.get(position); 
     } 
    } 
} 

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

      app:layout_scrollFlags="scroll|enterAlways" 
      app:popupTheme="@style/ThemeOverlay.AppCompat.Light" > 
     </android.support.v7.widget.Toolbar> 

     <android.support.design.widget.TabLayout 
      android:id="@+id/tabs" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"

      app:tabGravity="fill" > 
     </android.support.design.widget.TabLayout> 

    </android.support.design.widget.AppBarLayout> 

    <android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" > 
    </android.support.v4.view.ViewPager> 

</android.support.design.widget.CoordinatorLayout> 

その他のもの（フラグメントおよびそのレイアウト）が適切に設定されています。今、問題は、MainActivity.javaのline 44に存在するfuntion tabLayout.setupWithViewPager(viewPager);を使用して、viewPagerでtablayoutを含めると、アプリケーションがクラッシュすることです。アプリケーションはクラッシュせず、期待どおりに実行されます（バー上にタブはありませんが、フラグメントは存在しません）。 アプリのクラッシュレポートはここにある：私はなぜこれが起こっている知らない

。それを解決するにはどうすればよいですか？また、このクラッシュの理由も記入してください。

編集：ライブラリcompile com.android.support:design:23.1.1'をbuild.gradleに含めましたが、それでもまったく同じエラーが表示されます。私はプロジェクトをきれいにしてから再構築しました。私は、ライブラリの同じバージョンをインストールしているし、それはまだ仕事を文句を言わない

：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "com.example.cortana.testing" 
     minSdkVersion 15 
     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-v7:23.4.0' 
    compile 'com.android.support:design:23.1.1' 
} 

EDIT 2： build.gradleはこのようになります。誰か他のアイディアを提案してもらえますか？ 私が前に言ったように、すべてを上回る機能は、tablayout.setupWithViewPager(viewPager);です。私がそれをコメントアウトすると、アプリは正常に動作します。

Answer 1

これは、クラスローダーがクラスandroid.support.v7.internal.widget.TintManagerを見つけることができないために発生しています。

あなたはおそらくあなたのbuild.gradleにこれを追加する必要があります：

compile 'com.android.support:appcompat-v7:24.0.0' 
compile 'com.android.support:design:24.0.0' 

ところで、あなたはサポートライブラリのバージョンを混在させることはできません。投稿を編集して投稿を表示しています：

compile 'com.android.support:appcompat-v7:23.4.0' 
compile 'com.android.support:design:23.1.1' 

これはしないでください（23.4.0と23.1.1の組み合わせ）。 23.4.0または23.1.1を使用してください。多くのバグを解決するので、最新（24.0.0）を使用することをお勧めします。

「すべてのgradleプロジェクトをリフレッシュする」ことを忘れないでください。

PS：OWええ、アーヤスターク@は、同じでなければなりませ離れハウンド;-)

Answer 2

サポートライブラリと設計ライブラリのバージョンから滞在してください。

compile 'com.android.support:appcompat-v7:23.1.0' 
    compile 'com.android.support:design:23.1.0' 

またはそれをしようと同様に

..私はそれが動作を期待

android { 
........ 
    repositories { 
     maven { url 'http://repo1.maven.org/maven2' } 
    } 
.......... 
    } 

...

Answer 3

は、アンドロイド（https://code.google.com/p/android/issues/detail?id=180027）

あなたがそのスレッドに従うならば、あなたがハッキングソリューションやライブラリの一部を見ることができるのバグがあります。あなたの最後にどうやって解決しましたか？
