NavigationView的布局文件
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/navigation_background_light"
android:overScrollMode="never"
app:headerLayout="@layout/layout_navigation_header"
app:menu="@menu/navigation_main" />
</android.support.v4.widget.DrawerLayout>
下面才是关键
1、app:headerLayout="@layout/layout_navigation_header"
这条代码的作用就是设置导航抽屉的样子
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout android:id="@+id/header_container"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="200dp"
android:clickable="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimary">
<ImageView
android:id="@+id/background_image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|end|bottom"
android:clickable="true"
android:src="@drawable/home_menu_bg_click"
android:tint="@color/nav_head_image_background" />
</FrameLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:paddingTop="@dimen/activity_vertical_margin">
<tingyuxuan.hosition.zxyoyo.com.tingyuxuan.view.design.CircleImageView
android:id="@+id/user_avatar_view"
android:layout_width="74dp"
android:layout_height="74dp"
android:layout_gravity="start|top"
android:layout_marginEnd="16dp"
android:layout_marginStart="@dimen/activity_vertical_margin"
android:layout_marginTop="20dp"
android:src="@drawable/ico_user_default"
app:border_color="@android:color/white"
app:border_width="1dp" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_marginEnd="20dp"
android:layout_marginTop="20dp"
android:orientation="horizontal">
<ImageView
android:id="@+id/iv_head_noftiy"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_navigation_header_notification" />
</LinearLayout>
<LinearLayout
android:id="@+id/subtitle_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/user_avatar_view"
android:layout_gravity="bottom"
android:layout_marginStart="10dp"
android:background="?attr/selectableItemBackground"
android:orientation="vertical"
android:paddingTop="5dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
android:padding="5dp">
<TextView
android:id="@+id/user_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textColor="@color/white"
android:textSize="16sp" />
<TextView
android:id="@+id/user_level"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="3dp"
android:background="@drawable/white_border"
android:text="LV1"
android:gravity="center"
android:textColor="@color/white"
android:textSize="10sp" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="3dp"
android:background="@drawable/round_wihte_bg"
android:padding="3dp"
android:text="@string/app_name"
android:textColor="@color/nav_head_roung_text_background"
android:textSize="10sp" />
<TextView
android:text="@string/header_introduce"
android:id="@+id/user_other_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:textColor="@color/white"
android:textSize="14sp" />
</LinearLayout>
</RelativeLayout>
</FrameLayout>
2、app:menu="@menu/navigation_main"
这条代码的作用是设置导航抽屉中每个Item
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/item_home"
android:checked="true"
android:icon="@drawable/ic_home_black_24dp"
android:title="@string/item_home" />
<item
android:id="@+id/item_serach"
android:icon="@drawable/ic_action_search"
android:title="图书搜索" />
</group>
<group
android:id="@+id/group_user"
android:checkableBehavior="single">
<item
android:id="@+id/item_favourite"
android:icon="@drawable/ic_star_black_24dp"
android:title="@string/item_favourite" />
<item
android:id="@+id/item_history"
android:icon="@drawable/ic_history_black_24dp"
android:title="@string/item_history" />
</group>
<group android:checkableBehavior="single">
<item
android:id="@+id/item_settings"
android:icon="@drawable/ic_settings_black_24dp"
android:title="@string/item_settings" />
<item
android:id="@+id/item_manager"
android:icon="@drawable/ic_manager"
android:title="@string/item_manager" />
<item
android:id="@+id/item_exit"
android:icon="@drawable/ic_exit_to_app_black_24dp"
android:title="@string/item_exit" />
</group>
</menu>
之后就是在Activity中具体引用了
/*初始化NavigationView里面的内容*/
private void initNavigationView() {
mNavigationView.setNavigationItemSelectedListener(this);
View headerView = mNavigationView.getHeaderView(0);
CircleImageView mUserAvatarView = (CircleImageView) headerView.findViewById(R.id.user_avatar_view);
TextView mUserName = (TextView) headerView.findViewById(R.id.user_name);
TextView mUserLevel = (TextView) headerView.findViewById(R.id.user_level);
String name = getSharedPreferences("user", MODE_PRIVATE).getString("username", "听雨喧");
userLevel = DbUtil.getUserLevel(this, name);
mUserLevel.setText("LV"+ userLevel);
//设置名字
mUserName.setText(name);
}
/*重写onNavigationItemSelected方法，为每个点击item设置不同的效果*/
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.item_exit:
//切换帐号
getSharedPreferences("user", MODE_PRIVATE).edit().putString("username","").commit();
startActivity(new Intent(this,LoginActivity.class));
finish();
break;
//主页
case R.id.item_home:
toggleDrawer();
changeFragmentIndex(item, 0);
boolean update = getSharedPreferences("book", MODE_PRIVATE).getBoolean("update", false);
//System.out.println("-0-----------------dianjile--item_home:"+update);
if(update){
homeFragment.reFreshData();
}
break;
//管理界面
case R.id.item_manager:
toggleDrawer();
if(userLevel<2){
ToastUtil.showLong(this,"抱歉，只有管理员才能进入");
}else {
changeFragmentIndex(item, 1);
}
break;
//收藏图书界面
case R.id.item_favourite:
toggleDrawer();
changeFragmentIndex(item, 2);
break;
//设置界面
case R.id.item_settings:
toggleDrawer();
changeFragmentIndex(item,3);
break;
case R.id.item_history:
toggleDrawer();
changeFragmentIndex(item, 4);
break;
case R.id.item_serach:
toggleDrawer();
changeFragmentIndex(item,5);
break;
}
return false;
}
