java如何删除“未找到与安卓:minHeight=“”匹配的资源”错误？属性/操作栏大小“

Question

大家好，我正在制作一个应用程序，上面有Tabhost/Tabtoolbar，下面还有viewerpage。我的toolbar_layout.xml文件中有错误

错误显示在安卓:minHeight="?安卓:attr/actionBarsize行中，原因如下：

no resource found that matches the given name

每次在应用程序中创建新的片段java类和片段xml文件时，我都会遇到这个错误

下面是我的代码。Plz帮我解决这个错误，我在我的Android studio中使用Android 5.1版本

提前谢谢

工具栏布局xml文件

<?xml version="1.0" encoding="utf-8"?>
<安卓.support.v7.widget.Toolbar
    xmlns:app="http://schemas.安卓.com/apk/res-auto"
    xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    安卓:layout_width="match_parent" 安卓:layout_height="wrap_content"
    安卓:minHeight="?attr/actionBarsize"
    安卓:background="?attr/colorPrimary"
    安卓:fitsSystemWindows="true"
    安卓:id="@+id/toolbar"
    app:theme="@style/Base.ThemeOverlay.AppCompat.Dark.ActionBar">

</安卓.support.v7.widget.Toolbar>

主xml文件

<RelativeLayout
    xmlns:app="http://schemas.安卓.com/apk/res-auto"
    xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    xmlns:tools="http://schemas.安卓.com/tools"
    安卓:layout_width="match_parent"
    安卓:layout_height="match_parent"
    tools:context="com.example.mohammadzakriya.tabhost2.MainActivity">

    <安卓.support.design.widget.AppBarLayout
        安卓:layout_width="match_parent"
        安卓:layout_height="wrap_content">

        <include
            安卓:layout_width="match_parent"
            安卓:layout_height="wrap_content"
            layout="@layout/toolbar_layout"/>

        <安卓.support.design.widget.TabLayout
            安卓:layout_width="match_parent"
            安卓:layout_height="wrap_content"
            安卓:id="@+id/tabLayout"
            app:tabMode="fixed"
            app:tabGravity="fill"
            ></安卓.support.design.widget.TabLayout>

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

    <安卓.support.v4.view.ViewPager
        安卓:layout_width="match_parent"
        安卓:layout_height="wrap_content"
        安卓:id="@+id/viewPager"></安卓.support.v4.view.ViewPager>
</RelativeLayout>

维护性java文件

public class MainActivity extends AppCompatActivity {

    Toolbar toolbar;
    TabLayout tabLayout;
    ViewPager viewPager;
    ViewPagerAdapter viewPagerAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar =(Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        tabLayout =(TabLayout)findViewById(R.id.tabLayout);
        viewPager =(ViewPager) findViewById(R.id.viewPager);
        viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
        viewPagerAdapter.addFragments(new HomeFragment(),"Home");
        viewPagerAdapter.addFragments(new Database(),"Database");
        viewPagerAdapter.addFragments(new contact(),"contact");
        tabLayout.setupWithViewPager(viewPager);

    }
}

查看页面适配器

public class ViewPagerAdapter extends FragmentPagerAdapter{

    ArrayList<Fragment> fragments = new ArrayList<>();
    ArrayList<String>  tabTitles = new ArrayList<>();

    public void addFragments(Fragment fragments,String titles){
        this.fragments.add(fragments);
        this.tabTitles.add(titles);
    }



    public ViewPagerAdapter(FragmentManager fm){

        super(fm);
    }


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

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

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

我的身材。gradle（模块：应用程序）

apply plugin: 'com.安卓.application'

安卓 {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.example.mohammadzakriya.tabhost2"
        minSdkVersion 22
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-安卓.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.安卓.support:appcompat-v7:24.1.1'
    compile 'com.安卓.support:design:24.1.1'
}

Answer 1

改变这一点：

android:minHeight="?attr/actionBarsize"

致：

android:minHeight="?attr/actionBarSize"

请注意actionBarSize带有大写字母S

Answer 2

使用android:minHeight="?android:actionBarSize"
