侧滑菜单

//首先写布局，最大一层的布局写DrawerLayout 
.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mydraw"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.bawei.day005.MainActivity">
//这里写的是主页面
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical">
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/open"
android:gravity="center"
android:text="打开侧滑菜单"/>

//这里写的是侧滑出来的布局
android:layout_width="240dp"
android:layout_height="match_parent"
android:id="@+id/lv"
android:layout_gravity="start"
android:dividerHeight="1dp"
android:divider="#f00"
android:entries="@array/books"
android:background="#fff"
>
.support.v4.widget.DrawerLayout>
//然后写主函数
public class MainActivity extends AppCompatActivity {
private DrawerLayout drawerLayout;
private ListView lv;
private Button open;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.mydraw);
lv = (ListView) findViewById(R.id.lv);
open= (Button) findViewById(R.id.open);
//按钮点击监听
open.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//打开抽屉
drawerLayout.openDrawer(lv);
}
});
//listview点击监听
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView view）{
//关闭抽屉
drawerLayout.closeDrawer(lv);
String s=list.get(postion).gettext;
open.settext(s);
}
