Question

I have a layout XML file straight from the tutorial:

layout/partnertrial_summary.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>

In my Activity class, I try to use the following code, but if fails:

mTabHost = findViewById(R.layout.partnertrial_summary.tabhost);

which fails. However, it validates the R.layout.partnertrial_summary part in Green, but when I try to auto-popup the members of partnertrial_summary it yields nothing.

I assume the XML is valid because it came straight from Android, so it’s something I am doing wrong on my end. Note that my Activity is not a TabActivity, but I thought it would be okay to use a regular one and add a TabHost, implementing the appropriate listeners. Correct me if my thinking is wrong.

Answer 1

mTabHost = findViewById(R.layout.partnertrial_summary.tabhost);

replace the above as below

LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.partnertrial_summary,null);
 mTabHost = (TabHost)view.findViewById(R.id.tabhost);

layout can be inflated but cannot be find using findViewById()
