Spinner in tab is not shown

This is my activity code

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.input_transaction);

    tabHost = getTabHost();
    tabHost.addTab(tabHost.newTabSpec(getString(R.string.tab_in))
                          .setIndicator(getString(R.string.tab_in))
                          .setContent(R.id.tab_in));
    tabHost.addTab(tabHost.newTabSpec(getString(R.string.tab_out))
                          .setIndicator(g开发者_StackOverflow中文版etString(R.string.tab_out))
                          .setContent(R.id.tab_out));
    tabHost.addTab(tabHost.newTabSpec(getString(R.string.tab_transfer))
                          .setIndicator(getString(R.string.tab_transfer))
                          .setContent(R.id.tab_transfer));
    tabHost.setCurrentTabByTag(getString(R.string.tab_out));
}

Layout part for current tab

<LinearLayout android:id="@+id/tab_out"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_weight="1">
    <TextView android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_marginTop="10dip"
              android:text="@string/planet_prompt"/>
    <Spinner android:id="@+id/spinner"
             android:layout_width="fill_parent"
             android:layout_height="wrap_content"
             android:prompt="@string/planet_prompt"/>
</LinearLayout>

And screen of what I got

So, what should I do to make spinner present in tab, and why is it happening? Thanks!

You've told your text view to "Fill Parent", so it has pushed the spinner out.

Add this to both your spinner and textview XML:

android:layout_weight="1"
