Question

这是我的代码：

tabHost = (FragmentTabHost) findViewById(R.id.tabhost);
    tabHost.setup(this, getSupportFragmentManager(), R.id.tabcontent);
    tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Lengüeta 1"),
            Tab1.class, null);
    tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Lengüeta 2"),
            Tab2.class, null);
    tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("Lengüeta 3"),
            Tab3.class, null);

在我的XML中：

<android.support.v4.app.FragmentTabHost 
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <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"
            android:orientation="horizontal"/>
        <FrameLayout
            android:id="@+id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="0dp"/>
    </LinearLayout>
</android.support.v4.app.FragmentTabHost>

我得到了这个例外：

我尝试将id属性更改为“android.R.id.tabcontent”。我试图删除R类，当然还有清理和重建。在2015年摆脱这种例外的任何帮助......？

Answer 1

如堆栈跟踪所示，android:id属性必须不是@+id/tabcontent，而是@android:id/tabcontent

我的TabHost有一个带有该ID的FrameLayout
