1 :DrawerLayout侧边栏用于实现如图所示的效果:
2:跟布局XML代码如下 ,第一个元素标签为页面显示内容,第二个元素标签用于显示DrawerLayout的布局样式,我用了一个ListView展示。
<android.support.v4.widget.DrawerLayout android:layout_width="match_parent" android:layout_height="match_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/root_drawerlayout"> <!-- 第一部分为主页面显示内容--> <LinearLayout android:id="@+id/main_contant" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="DrawerLayout的学习" android:textSize="20dp" /> </LinearLayout> <!--第二部分为DrawerLayout的视图资源--> <ListView android:id="@+id/left_drawerlayout" android:layout_width="180dp" android:layout_height="match_parent" android:layout_gravity="end" android:background="#ffffcc" android:choiceMode="singleChoice" android:divider="@android:color/transparent" android:dividerHeight="5dp" /> </android.support.v4.widget.DrawerLayout>
3:Activity代码如下,通过点击item跟换了Fragment。Fragment与Activity之间传递参数可通过SetArgument(New Bundle)实现,在Bundle中绑定数据;
1 package cativity.cyq.drawerlayoutlearn; 2 3 import android.support.v4.app.ActionBarDrawerToggle; 4 import android.support.v4.widget.DrawerLayout; 5 import android.support.v7.app.ActionBarActivity; 6 import android.os.Bundle; 7 import android.view.View; 8 import android.widget.AdapterView; 9 import android.widget.ArrayAdapter; 10 import android.widget.ListView; 11 import android.widget.Toast; 12 13 import java.util.ArrayList; 14 15 import static android.widget.Toast.LENGTH_SHORT; 16 17 18 public class MainActivity extends ActionBarActivity implements AdapterView.OnItemClickListener { 19 20 private DrawerLayout drawerLayout; 21 private ListView menuListview; 22 private ArrayList<String> menuData; 23 private ArrayAdapter<String> menuAdapter; 24 private ActionBarDrawerToggle mDrawerToggle; 25 26 @Override 27 protected void onCreate(Bundle savedInstanceState) { 28 super.onCreate(savedInstanceState); 29 setContentView(R.layout.activity_main); 30 31 drawerLayout = (DrawerLayout) findViewById(R.id.root_drawerlayout); 32 menuListview = (ListView) findViewById(R.id.left_drawerlayout); 33 menuData = new ArrayList<>(); 34 for (int i = 0; i < 7; i++) 35 menuData.add("菜单项" + i); 36 menuAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, menuData); 37 menuListview.setAdapter(menuAdapter); 38 39 menuListview.setOnItemClickListener(this); 40 41 //监听DrawerLayout的打开和关闭事件 42 mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.menubar, R.string.drawerOpen, R.string.drawerClose) { 43 @Override 44 public void onDrawerOpened(View drawerView) { 45 super.onDrawerOpened(drawerView); 46 Toast.makeText(getApplication(), "打开", LENGTH_SHORT).show(); 47 } 48 49 @Override 50 public void onDrawerClosed(View drawerView) { 51 super.onDrawerClosed(drawerView); 52 Toast.makeText(getApplication(), "关闭", Toast.LENGTH_SHORT).show(); 53 } 54 }; 55 drawerLayout.setDrawerListener(mDrawerToggle); 56 57 } 58 59 /* 为DrawerLayout的元素设置监听事件 */ 60 @Override 61 public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 62 Toast.makeText(this, "你选择的是:" + position, LENGTH_SHORT).show(); 63 MyFragment contentFragment = new MyFragment(); 64 /*通过setArgument(new Bundle())在Fragment的控制器和视图之间传递参数*/ 65 Bundle args = new Bundle(); 66 args.putString("fragmentdata", menuData.get(position)); 67 contentFragment.setArguments(args); 68 69 getFragmentManager().beginTransaction().replace(R.id.main_contant, contentFragment).commit(); 70 71 drawerLayout.closeDrawer(menuListview); 72 } 73 74 75 }
