二进制 XML 文件第 5 行：膨胀自定义视图类 SlidingTabLayout 时出错答案

【问题标题】：Binary XML file line #5: Error inflating custom View class SlidingTabLayout二进制 XML 文件第 5 行：膨胀自定义视图类 SlidingTabLayout 时出错
【发布时间】：2015-06-24 16:33:51
【问题描述】：

在我们的项目中，我们更改了一些 API 调用，因此我不得不更改一些对象并更改启动画面调用，但 MainActivity 和自定义视图保持不变，并且我没有更改它们很长一段时间，但突然当我在 SplashScreen 上调用 finish() 并尝试启动 MainActivitiy 时，会发生一些错误。

这是我的错误的 Logcat 输出

这是我的 MainActivity.clas（第 65 行是 setContentView(R.layout.main)）

public class MainActivity extends AppCompatActivity implements NavigationDrawerCallbacks {

    private NavigationDrawerFragment mNavigationDrawerFragment;

    @InjectView(R.id.view_pager) ViewPager viewPager;
    @InjectView(R.id.container) FrameLayout container;
    @InjectView(R.id.sliding_tabs) SlidingTabLayout slidingTabLayout;
    @InjectView(R.id.toolbar_actionbar) Toolbar toolbar;
    ActionBar actionBar;
    PublisherInterstitialAd mPublisherInterstitialAd;
    static Context context;
    boolean isLoaded = false;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ButterKnife.inject(this);
        context = this;

        if(getResources().getBoolean(R.bool.is_tablet)){
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        } else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }

        setSupportActionBar(toolbar);
        actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayShowTitleEnabled(false);
        }

        mNavigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_drawer);

        mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), toolbar);
        if (mNavigationDrawerFragment.isDrawerOpen()) {
            mNavigationDrawerFragment.closeDrawer();
        }

        slidingTabLayout.setDistributeEvenly(true);
        slidingTabLayout.notificationsCount = 8;
        MyPagerAdapter adapterViewPager = new MyPagerAdapter(getSupportFragmentManager());
        viewPager.setAdapter(adapterViewPager);
        slidingTabLayout.setViewPager(viewPager);
        slidingTabLayout.setSelectedIndicatorColors(getResources().getColor(R.color.indicator));

        slidingTabLayout.updateNotificationCount(155);

        isLoaded = true;
    }

这是 main.xml 文件

<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_height="match_parent">

<include android:id="@+id/toolbar_actionbar" layout="@layout/toolbar"
    android:layout_width="match_parent" android:layout_height="wrap_content" />

<android.support.v4.widget.DrawerLayout android:id="@+id/drawer"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent"
    android:layout_below="@+id/toolbar_actionbar">

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <FrameLayout android:id="@+id/container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:visibility="gone"/>

        <android.support.v4.view.ViewPager
            android:id="@+id/view_pager"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>

    <fragment android:id="@+id/fragment_drawer"
        android:name="pribozic.sconnected.fragments.NavigationDrawerFragment"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent" android:layout_gravity="start"
        app:layout="@layout/fragment_navigation_drawer"
        tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>

</RelativeLayout>`

我不知道这是否是相对的，但我的 SlidingTabLayout 视图直到昨天都运行良好，除了我创建的一些自定义对象和我为新 API 调用添加的新 RestClient 服务外，没有任何变化。

我可以提供 SlidingTabLayout 代码，但代码量很大。说有问题的那一行是构造函数，也是我创建 SlidingTabStrip 的地方。也许它与上下文有关？但是视图应该是在 XML 中创建的，我该如何更改上下文？

【问题讨论】：

标签： java android xml crash runtime-error

【解决方案1】：

抱歉，如果您还没有得到答案！

这是因为您试图在未在 main.xml 中定义的情况下扩展 SlidingTabLayout.java 视图

可能的修复：

检查 pribozic.sconnected.views.SlidingTabLayout.java 文件夹中是否有 SlidingTabLayout.java。

然后

在 main.xml 中指定 SlidingTabLayout。

<pribozic.sconnected.views.SlidingTabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

希望对你有帮助
