Question

Hi i have set up a custom title bar but the app crashes and i don’t get any error log in LogCat, i’m going crazy. Here’s is some code, can you experts see what’s wrong?

boolean isCustomTitleSupported;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        isCustomTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.about);
        customizeTitleBar("My Title");

    public void customizeTitleBar(String title){
        if(isCustomTitleSupported){
            getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.customtitlebar);
            TextView customTitleText = (TextView)findViewById(R.id.customtitle);
            customTitleText.setText(title);
            customTitleText.setTextColor(Color.WHITE);
        }
    }

customtitlebar.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal" 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

    <TextView android:id="@+id/customtitle"
        android:layout_width="wrap_content" 
        android:layout_height="fill_parent"
        android:textStyle="bold"
        android:padding="3px" 
        />

</LinearLayout>

some help will be appreciated

Thanks!!

EDIT: i noticed that i wasn’t extending Activity but BaseActivity a superclass i created to have the menu available in all of my activities. So i changed back to extend Activity and it’s working but this is a problem because i need menus too. Is there any tricks so i could keep extending BaseActivity and even get the title bar to work?

Answer 1

You are trying to extract the customtitle TextView from the wrong layout. When you use findViewById it defaults to your current activity’s layout, which you set to R.layout.about. You need to use a layout inflater to inflate R.layout.customtitlebar and then call findViewById from that (since the customtitle view is in the customtitlebar layout).

Something like this:

View view = getLayoutInflater().inflate(R.layout.customtitlebar);
TextView customTitleText = (TextView)view.findViewById(R.id.customtitle);
