关于Android Frameworks基础：android.view.InflateException二进制XML＃18错误夸大类

问题描述

当我点击导航栏上的方形按钮（recents应用程序）时，我得到了systemUI fc。我已获取有关该详细日志的日志。

这是日志

这是RecentsActivity.java，其中错误在第384行

第384行：-`//设置“最近”布局setContentView（R.layout.recents）;

以及最近的Activitys.java的一部分

/** Called with the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // For the non-primary user, ensure that the SystemServicesProxy and configuration is
    // initialized
    RecentsTaskLoader.initialize(this);
    SystemServicesProxy ssp = RecentsTaskLoader.getInstance().getSystemServicesProxy();
    mConfig = RecentsConfiguration.reinitialize(this, ssp);

    // Initialize the widget host (the host id is static and does not change)
    mAppWidgetHost = new RecentsAppWidgetHost(this, Constants.Values.App.AppWidgetHostId);

    // Set the Recents layout
    setContentView(R.layout.recents);
    mRecentsView = (RecentsView) findViewById(R.id.recents_view);
    mRecentsView.setCallbacks(this);
    mRecentsView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
            View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN |
            View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
    mEmptyViewStub = (ViewStub) findViewById(R.id.empty_view_stub);
    mDebugOverlayStub = (ViewStub) findViewById(R.id.debug_overlay_stub);
    mScrimViews = new SystemBarScrimViews(this, mConfig);
    mStatusBar = ((SystemUIApplication) getApplication())
            .getComponent(PhoneStatusBar.class);
    inflateDebugOverlay();

这是包/systemui/res/layout/recents.xml中的recents.xml

<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" 
android:layout_height="match_parent">
<!-- Status Bar Scrim View -->
<ImageView
    android:id="@+id/status_bar_scrim"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal|top"
    android:scaleType="fitXY"
    android:src="@drawable/recents_status_gradient" />

<!-- Recents View -->
<com.android.systemui.recents.views.RecentsView
    android:id="@+id/recents_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:focusable="true" />

<!-- Empty View -->
<ViewStub android:id="@+id/empty_view_stub"
       android:layout="@layout/recents_empty"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />

<!-- Debug Overlay View -->
<ViewStub android:id="@+id/debug_overlay_stub"
       android:layout="@layout/recents_debug_overlay"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />

<!-- Nav Bar Scrim View -->
<ImageView
    android:id="@+id/nav_bar_scrim"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal|bottom"
    android:scaleType="fitXY"
    android:src="@drawable/recents_lower_gradient" />

<include layout="@layout/floating_action_button" />

请帮我该怎么办...

希望有一个解决办法

谢谢
