Today we are learning about the section header in android.
Listview are commonly used to display a large set of similar data. But in the section header list we can show the similar data list in the different and separate section of the list view.Here I am using the adapter class for loading the view of list one by one by using get view method.
So lets start the coding about the section header.

Item.java

public boolean isSection();

private final String title;
public SectionItem(String title) {
this.title = title;
}

return title;
}
@Override
public boolean isSection() {
return true;
}
}

this.title = title;
this.subtitle = subtitle;
}
@Override
public boolean isSection() {
return false;
}
}
