Android引入标题栏

title.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="horizontal"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:background="@drawable/title"
 >

 <Button
 android:id="@+id/b1"
 android:textColor="#fff"
 android:layout_gravity="center"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="上一页"/>
 <TextView
 android:textColor="#fff"
 android:layout_gravity="center"
 android:layout_width="wrap_content"
 android:gravity="center"
 android:layout_weight="1"
 android:layout_height="wrap_content"
 android:text="真香小说"/>
 <Button
 android:layout_gravity="center"
 android:id="@+id/b2"
 android:textColor="#fff"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="下一页"/>
</LinearLayout>

main.xml中引入开头

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="horizontal"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 >
 <include layout="@layout/title"/>

</LinearLayout>

在main.java中隐藏原来的标题栏

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ActionBar actionBar=getSupportActionBar();
        if(actionBar!=null){
            actionBar.hide();
        }
    }
