自定义窗口标题

1.主MainActivity 类代码如下：

public class MainActivity extends Activity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
		setContentView(R.layout.activity_main);
		getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);
	}
	public void add(View v) {

	}
}

2.style.xml

<resources>

    <style name="customTheme" parent="android:Theme.Light">
        <item name="android:windowContentOverlay">@drawable/nonecolor</item>
        <item name="android:windowTitleSize">54dp</item>
        <item name="android:windowTitleBackgroundStyle">@style/bg</item>
    </style>

    <style name="bg">
        <item name="android:background">@drawable/rectangle</item>
    </style>

</resources>

3.drawable文件夹下rectangle.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <gradient
        android:angle="270"
        android:endColor="#1DC9CD"
        android:startColor="#A2E0FB" />
    <padding
        android:bottom="2dp"
        android:left="2dp"
        android:right="2dp"
        android:top="2dp" />
</shape>
