android change titlebar diynamic

출처 : http://stackoverflow.com/questions/3438276/change-title-bar-text-in-android

you can Change the Title of each screen (i.e. Activity) by setting their Android:label

   <activity android:name=".Hello_World"

                  android:label="This is the Hello World Application">

   </activity>

=> Custom - Title - bar

---

But if you want to Customize title-bar in your way, i.e. Want to put Image icon and custom-text, then following code is running for me:

main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    >


</LinearLayout>

titlebar.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

 android:layout_width="400px" 

  android:layout_height="fill_parent"

  android:orientation="horizontal">


<ImageView android:id="@+id/ImageView01" 

            android:layout_width="57px" 

            android:layout_height="wrap_content"

            android:background="@drawable/icon1">


</ImageView>


<TextView 


  android:id="@+id/myTitle" 

  android:text="This is my new title" 

  android:layout_width="fill_parent" 

  android:layout_height="fill_parent" 

  android:textColor="@color/titletextcolor"

   />

</LinearLayout>

TitleBar.java

public class TitleBar extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);


           final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);


           setContentView(R.layout.main);




           if ( customTitleSupported ) {

               getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar);

               }


           final TextView myTitleText = (TextView) findViewById(R.id.myTitle);

           if ( myTitleText != null ) {

               myTitleText.setText("NEW TITLE");


               // user can also set color using "Color" and then "Color value constant"

              // myTitleText.setBackgroundColor(Color.GREEN);

           }

   }

}

strings.xml

The strings.xml file is defined under the values folder.

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <string name="hello">Hello World, Set_Text_TitleBar!</string>

    <string name="app_name">Set_Text_TitleBar</string>


    <color name="titlebackgroundcolor">#3232CD</color>

    <color name="titletextcolor">#FFFF00</color>


</resources>
