侧滑菜单

//首先写布局，最大一层的布局写DrawerLayout <android.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<LinearLayoutandroid:layout_width="wrap_content"android:layout_height="match_parent"android:orientation="vertical"><Buttonandroid:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/open"android:gravity="center"android:text="打开侧滑菜单"/></LinearLayout>//这里写的是侧滑出来的布局<ListViewandroid: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"></ListView></android.support.v4.widget.DrawerLayout>//然后写主函数public class MainActivity extends AppCompatActivity {private DrawerLayout drawerLayout;private ListView lv;private Button open;@Overrideprotected 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() {@Overridepublic void onClick(View v) {//打开抽屉drawerLayout.openDrawer(lv);}});//listview点击监听lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView view）{//关闭抽屉drawerLayout.closeDrawer(lv);String s=list.get(postion).gettext;open.settext(s);}
