Question

当我尝试运行我的应用程序时，遇到了这个非常奇怪的错误。我认为是由于我的标签。这是错误:

这是我的 xml 文件:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:background="#ccc" >

        <TextView
            android:id="@+id/titleTV"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="5dp"
            android:text="Bytes"
            android:textSize="20dp" />
    </LinearLayout>

    <TabHost
        android:id="@android:id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/linearLayout1" >

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

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
            </TabWidget>

            <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >

                <LinearLayout
                    android:id="@+id/tab1"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab2"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab3"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>

</RelativeLayout>

还有我的 OnCreate 方法:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

tabHost = (TabHost)findViewById(android.R.id.tabhost);
tabHost.setup();

TabSpec ts = tabHost.newTabSpec("Home").setIndicator("Home").setContent(new Intent().setClass(this,MainActivity.class));
tabHost.addTab(ts);
ts = tabHost.newTabSpec("Quests").setIndicator("Quests").setContent(new Intent().setClass(this,Jobs.class));
tabHost.addTab(ts);

tabHost.setCurrentTab(0);

我以前从未见过这个错误。由于某种原因，我的 xml 文件出现膨胀问题？

您正在通过尝试加载来创建无限循环:
MainActivity _{与选项卡中的 MainActivity、 与选项卡中的 MainActivity、 与选项卡中的 MainActivity、 与选项卡中的 MainActivity、 与选项卡中的 MainActivity、 选项卡中的 MainActivity，选项卡中包含 MainActivity，选项卡中包含 MainActivity，选项卡中包含 MainActivity，}

这是麻烦的一行:

TabSpec ts = tabHost.newTabSpec("Home").setIndicator("Home").setContent(new Intent().setClass(this,MainActivity.class));

我感觉你的完整 LogCat 显示根本原因是 StackOverflowException...

无论如何，您需要创建一个新类，将其命名为“Home”，其中 MainActivity 加载选项卡，而 Home 是您的默认屏幕。
