Título personalizado y setTitle en Android

I have create a simple custom title which is showing perfectly. However I am not sure what id to give my TextView in order for the setTitle method to work its magic.

My first choice was @android:id/title but that did not work.

Example I have defined a custom title layout in xml and added it to my activity.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@android:color/transparent" >

        android:src="@drawable/logo" />

        android:text="TextView" />

The TextView is now the "title" container. What I want is for the android:label value from the manifest to automatically be put in this new title TextView.

Ie. the default method setTitle must be adding this value to some defined view id - I just need that id.

setTitle sets the title of the activity, it has nothing to do with TextView's you need to use setText() to set the text of a TextView:

((TextView)findViewById(R.id.text_view_id)).setText("TextView text");

Yes I know how to set the text of a text view. What I am asking for is an id to use in my custom title layout so that the setTitle method will still work. - Slott

I had to create a similar feature with a custom title. I highly doubt you will be able to do it by matching an id, that would be a huge security flaw if Android allowed that. What I did was extend Activity and then override the setTitle method in a fashion like...

TextView mCustomTitle;

public void onCreate(Bundle savedInstanceState) {
     mCustomTitle = (TextView)findViewById(R.id.title);

public void setTitle(CharSequence title) {
    //you can override the other setTitle as well if you need it

This is more or less what I did. I included the title from the manifest also using getTitle. Ie. .setText(getTitle()); - Slott

Did you create it as a base class? I found that really took most of the hassle out of it? - Mike Israel

Yes I have a BaseActivity class that I extend from. It makes things easier but I still think it would be nice if the setTile could work with a custom title xml if the correct id was used for the testview holding the title. - Slott

@slott glad to hear it helped, if so please accept the answer. Also I am guessing that if they exposed that element it could lead to some huge security risks for malicious behaviors. - Mike Israel
