Implement custom title

App with custom title
App with custom title


Create /res/layout/custom_title.xml, to define the layout of your custom title bar.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

 <ImageView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"/>
    <TextView
        android:id="@+id/titletext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@android:color/white"
        android:textStyle="italic|bold"
        android:text="http://android-coding.blogspot.com/" />
    <ImageView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"/>

</LinearLayout>


MainActivity.java
package com.example.androidcustomtitle;

import android.os.Bundle;
import android.app.Activity;
import android.view.Window;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
  
  setContentView(R.layout.activity_main);
  
  if(customTitleSupported){
   getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);
   Toast.makeText(getApplicationContext(), 
     "Custom Title Applied", 
     Toast.LENGTH_LONG).show();
   
   //Set title text programmatically
   TextView titleText = (TextView)findViewById(R.id.titletext);
   titleText.setText("Android-Coding");
   
  }else{
   Toast.makeText(getApplicationContext(), 
     "FEATURE_CUSTOM_TITLE not supported!", 
     Toast.LENGTH_LONG).show();
  }

 }

}


Also modify AndroidManifest.xml to use style without title features on android:theme; otherwise "android.util.AndroidRuntimeException: You cannot combine custom titles with other title features" will be thrown. "@android:style/Theme.Light" and "@android:style/Theme.Black" have been tested work ok.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidcustomtitle"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Light" >
        <activity
            android:name="com.example.androidcustomtitle.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
