My TabHost HAS a FrameLayout with that id

Question

This is my code:

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);

In my XML:

<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>

I am getting this exception:

I have tried changing id attribute to "android.R.id.tabcontent". I tried to delete the R class, and of course clean and rebuild. Any help to get rid of this exception in 2015...?

Answer 1

as the stacktrace says, android:id attribute has to be not @+id/tabcontent, but @android:id/tabcontent
