AndroidUI 侧滑菜单  DrawerLayout的使用

AndroidUI 侧滑菜单  DrawerLayout的使用

直接上代码:

activity_main.xml:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"> <!-- 主视图 -->
<FrameLayout android:id="@+id/content_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout> <!-- 左侧菜单 -->
<ListView android:id="@+id/letf_menu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#ffffcc"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"> </ListView> </android.support.v4.widget.DrawerLayout>

MainActivity:

public class MainActivity extends Activity implements OnItemClickListener {
private DrawerLayout mDrawerLayout;
private ListView mListView;
private List<String> menuList;
private ArrayAdapter<String> adapter;
private ActionBarDrawerToggle toggle;
private String mTitle;
//1.创建DrawerLayout并填充内容
//2.实现侧滑菜单的点击事件,点击后切换内容
//3.在导航条右侧显示搜索按钮,并实现打开网页功能
//4.实现当打开侧滑菜单后头部title的改变,并且隐藏其他menu;关闭侧滑菜单后显示Menu 变更title
//5.实现点击左上角导航按钮打开侧滑菜单功能
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//获取当前的title
mTitle=(String) getTitle(); //----------------1.--------------
// 为左侧抽屉菜单 添加内容
mDrawerLayout=(DrawerLayout) findViewById(R.id.drawer_layout);
mListView=(ListView) findViewById(R.id.letf_menu);
menuList=new ArrayList<String>();
for(int i=0;i<5;i++){
menuList.add("抽屉菜单0"+i);
}
adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, menuList);
mListView.setAdapter(adapter); //----------------2.--------------
//当点击左侧菜单 时,添加监听事件
mListView.setOnItemClickListener(this); //----------------4.--------------
//为 DrawerLayout 设置 ActionBarDrawerToggle 监听事件,来完成监听抽屉状态变化的功能。
//当侧拉菜单打开以后,显示title为请选择; 关闭以后显示原title
toggle=new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer
, R.string.open_drawer,R.string.close_drawer){ @Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle("请选择");
//重新绘制头部的Menu,当调用invalidateOptionsMenu时,系统会自动调用onPrepareOptionsMenu方法
invalidateOptionsMenu();
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActionBar().setTitle(mTitle);
//重新绘制头部的Menu
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(toggle); //----------------5.--------------
//开启ActionBar 上面的icon的功能
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
//----------------4.--------------
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
//获取侧拉菜单的打开状态
Boolean isOpen=mDrawerLayout.isDrawerOpen(mListView);
//当侧拉菜单 打开时,隐藏搜索按钮,当侧拉菜单关闭时,显示搜索按钮
menu.findItem(R.id.action_search).setVisible(!isOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
//----------------2.--------------
// 动态插入一个Fragment到FrameLayout中
Fragment fragment=new ContentFragment();
Bundle args=new Bundle();
args.putString("text", menuList.get(position));
fragment.setArguments(args);
//替换掉当前的Fragment内容
FragmentManager manager=getFragmentManager();
manager.beginTransaction().replace(R.id.content_layout, fragment).commit();
//关闭左侧菜单
mDrawerLayout.closeDrawer(mListView); } @Override
public boolean onOptionsItemSelected(MenuItem item) {
//----------------5.--------------
//将ActionBar与Drawer结合起来,点击左上角的菜单时,打开侧拉菜单
if(toggle.onOptionsItemSelected(item)){
return true;
}
//----------------3.--------------
//当点击搜索按钮的时候打开一个网站
switch (item.getItemId()) {
case R.id.action_search:
Intent intent=new Intent();
intent.setAction("android.intent.action.VIEW");
Uri uri=Uri.parse("http://www.fitnes.cn");
intent.setData(uri);
startActivity(intent);
break;
default:
break;
}
return super.onOptionsItemSelected(item);
} //----------------5.--------------
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
//调用ActionBarDrawerToggle.syncState()
//在Activity的onPostCreate()中;指示,ActionBarDrawerToggle与DrawerLayout的状态同步,
//并将ActionBarDrawerToggle中的drawer图标,设置为ActionBar的Home-Button的icon
toggle.syncState();
}
//----------------5.--------------
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
toggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

ContentFragment:

public class ContentFragment extends Fragment {
//----------------2.--------------
private TextView tv;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.content_fragment,container, false);
tv=(TextView) view.findViewById(R.id.txtView);
String text=getArguments().getString("text");
tv.setText(text);
return view;
}
}

content_fragment.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- 2. -->
<TextView android:id="@+id/txtView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

menu/main.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- 3. -->
<item android:id="@+id/action_search"
android:showAsAction="ifRoom|withText"
android:title="@string/webSerach"
android:icon="@drawable/action_search"/>
</menu>
