前言
经常我们使用Android APP时,会注意到很多app都有侧滑栏,比如网易云、B站、滴滴、QQ等。
效果展示
本篇博客一共实现了5种样式:
侧边栏样式一 Android原生风格
侧边栏样式二 B站 网易云 滴滴风格
侧边栏样式三 iOS侧滑风格
侧边栏样式四(仿QQ 5.0.0)风格
侧边栏样式五(仿QQ 8.0.0)风格
代码实现

xml布局:

android:textAlignment="center"

</LinearLayout>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
这里使用DrawerLayout+NavigationView实现的, NavigationView在标签里添加布局可以实现脚布局。
在menu文件添加item条目,
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<group
android:id="@+id/group1"
android:checkableBehavior="single">
<item
android:id="@+id/single_1"
android:icon="@drawable/ic_android_fill"
android:title="安卓"
app:actionLayout="@layout/bage_hint"/>
<item
android:id="@+id/single_2"
android:icon="@drawable/ic_apple_fill"
android:title="苹果"/>
</group>
<group
android:id="@+id/group2"
android:checkableBehavior="single">
<item
android:id="@+id/single_3"
android:icon="@drawable/ic_github_line"
android:title="github"/>
<item
android:id="@+id/single_4"
android:icon="@drawable/ic_wechat_fill"
android:title="wechat"/>
</group>
<item
android:title="子菜单">
<menu>
<item
android:id="@+id/item_2"
android:icon="@drawable/ic_taobao_fill"
android:title="淘宝"/>
<item
android:id="@+id/item_1"
android:icon="@drawable/ic_baidu_line"
android:title="百度"/>
<item
android:id="@+id/item_3"
android:icon="@drawable/ic_qq_fill"
android:title="腾讯"/>
</menu>
</item>
</menu>
bage_hint.xml布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="vertical">
<TextView
android:id="@+id/msg_bg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/badge_bg"
android:gravity="center"
android:text="0"
android:textColor="@android:color/white"
android:textSize="10sp"/>
</LinearLayout>
vip_view.xml布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="vertical">
<TextView
android:id="@+id/tv_vip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableStart="@drawable/ic_vip"
android:drawableLeft="@drawable/ic_vip"
android:gravity="center"
android:text="开通Vip 99元"
android:textColor="@android:color/holo_red_light"
android:textSize="12sp"/>
</LinearLayout>
其中需要注意的是app:actionLayout="@layout/bage_hint",actionLayout这里是item扩展布局,布局是从右向左显示,当太宽的时候,会遮盖item的内容。
Style1Activity.class代码:
public class Style1Activity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_style1);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
NavigationView navigationview = (NavigationView) findViewById(R.id.navigation_view);
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
setSupportActionBar(toolbar);//将toolbar与ActionBar关联
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, 0, 0);
drawer.setDrawerListener(toggle);//初始化状态
toggle.syncState();
/*---------------------------添加头布局和尾布局-----------------------------*/
//获取xml头布局view
View headerView = navigationview.getHeaderView(0);
//添加头布局的另外一种方式
//View headview=navigationview.inflateHeaderView(R.layout.navigationview_header);
//寻找头部里面的控件
ImageView imageView = headerView.findViewById(R.id.iv_head);
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "点击了头像", Toast.LENGTH_LONG).show();
}
});
navigationview.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
return false;
}
});
ColorStateList csl = (ColorStateList) getResources().getColorStateList(R.color.nav_menu_text_color);
//设置item的条目颜色
navigationview.setItemTextColor(csl);
//去掉默认颜色显示原来颜色 设置为null显示本来图片的颜色
navigationview.setItemIconTintList(csl);
//设置单个消息数量
LinearLayout llAndroid = (LinearLayout) navigationview.getMenu().findItem(R.id.single_1).getActionView();
TextView msg= (TextView) llAndroid.findViewById(R.id.msg_bg);
msg.setText("99+");
//设置条目点击监听
navigationview.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
//安卓
Toast.makeText(getApplicationContext(), menuItem.getTitle(), Toast.LENGTH_LONG).show();
//设置哪个按钮被选中
// menuItem.setChecked(true);
//关闭侧边栏
// drawer.closeDrawers();
return false;
}
});
}
}
侧边栏样式二 B站 网易云 滴滴
第二种方式第一种方式实现类似,只是调整了一下Toolbar与DrawerLayout顺序,国内大部分APP应用采用这种侧滑方式。
<?xml version="1.0" encoding="utf-8"?>
<!--侧边栏样式-->
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<!--主页内容-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<!--标题栏样式一-->
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:background="@color/colorPrimary"
app:subtitleTextColor="@android:color/white"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="样式2"
app:titleTextColor="@android:color/white">
</android.support.v7.widget.Toolbar>
<!--主页内容-->
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>
</LinearLayout>
<!--侧边栏内容-->
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigationview_header"
app:insetForeground="@android:color/transparent"
app:menu="@menu/menu_navigation">
<!--添加脚布局-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_gravity="bottom"
android:gravity="center"
android:orientation="horizontal">
<Button
android:id="@+id/footer_item_setting"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:adjustViewBounds="true"
android:background="@android:color/transparent"
android:drawableStart="@drawable/ic_setting"
android:drawableLeft="@drawable/ic_setting"
android:drawablePadding="1dp"
android:gravity="center"
android:paddingLeft="5dp"
android:text="设置"
android:textAlignment="inherit"
android:textColor="@color/colorPrimary"/>
<Button
android:id="@+id/footer_item_out"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@android:color/transparent"
android:drawableStart="@drawable/ic_out"
android:drawableLeft="@drawable/ic_out"
android:drawablePadding="1dp"
android:gravity="center"
android:paddingLeft="5dp"
android:text="退出"
android:textAlignment="center"
android:textColor="@color/colorPrimary"/>
</LinearLayout>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
但是还是注意几点侧滑时隐藏状态栏,这里我们可以将状态栏变成透明色,xml根布局设置为android:fitsSystemWindows="true",否则主布局会进入状态栏,在Activity当中添加如下代码实现状态栏透明:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
//5.x开始需要把颜色设置透明,否则导航栏会呈现系统默认的浅灰色
Window window = activity.getWindow();
View decorView = window.getDecorView();
//两个 flag 要结合使用,表示让应用的主体内容占用系统状态栏的空间
int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
decorView.setSystemUiVisibility(option);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
//导航栏颜色也可以正常设置
// window.setNavigationBarColor(Color.TRANSPARENT);
} else {
Window window = activity.getWindow();
WindowManager.LayoutParams attributes = window.getAttributes();
int flagTranslucentStatus = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
int flagTranslucentNavigation = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
attributes.flags |= flagTranslucentStatus;
// attributes.flags |= flagTranslucentNavigation;
window.setAttributes(attributes);
}
}
接着一个bug未解决,又出现一个问题,那就是侧滑时,状态栏存在阴影
最新的NavigationView控件作为侧滑内容,而谷歌把它写死了,一直都会有那个状态栏阴影,所以为NavigationView控件添加app:insetForeground=”@android:color/transparent” ,就可以完美解决这个问题。
【注意】如果NavigationView默认Menu布局无法满足你们公司UI设计狮的要求,那么就要可以使用这个绝招了,通过Fragment自定义NavigationView布局。
getSupportFragmentManager().beginTransaction().replace(R.id.navigation_view,
new NavigationViewFragment()).commit();
定义一个Fragment填充NavigationView,这样就可以显示Fragment的布局了。
侧边栏样式三 iOS风格侧滑
这种风格侧边栏这里使用DrawerLayout两个子布局之间切换实现,具体代码:
<?xml version="1.0" encoding="utf-8"?>
<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">
<!--主页内容-->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="@layout/activity_content3"/>
</FrameLayout>
<!--侧边栏内容-->
<FrameLayout
android:id="@+id/menu_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start">
<include layout="@layout/left_menu3"/>
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
Activity代码:
public class Style3Activity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//隐藏状态栏时,获取状态栏高度
int statusBarHeight = ScreenInfoUtils.getStatusBarHeight(this);
//隐藏状态栏
ScreenInfoUtils.fullScreen(this);
//初始化布局
setContentView(R.layout.activity_style3);
//初始化状态栏的高度
View statusbar = (View) findViewById(R.id.view_statusbar);
ConstraintLayout.LayoutParams params = new ConstraintLayout.LayoutParams(ConstraintLayout.LayoutParams.MATCH_PARENT, statusBarHeight);
statusbar.setLayoutParams(params);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
final DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
setSupportActionBar(toolbar);//将toolbar与ActionBar关联
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawerLayout, toolbar, 0, 0);
drawerLayout.addDrawerListener(toggle);//初始化状态
toggle.syncState();
//蒙层颜色
drawerLayout.setScrimColor(getResources().getColor(R.color.colorGray));
drawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
@Override
public void onDrawerStateChanged(int newState) {
}
@Override
public void onDrawerSlide(@NonNull View drawerView, float slideOffset) {
View mContent = drawerLayout.getChildAt(0);
View mMenu = drawerView;
ViewHelper.setTranslationX(mContent, mMenu.getMeasuredWidth() * slideOffset);
}
@Override
public void onDrawerOpened(@NonNull View drawerView) {
}
@Override
public void onDrawerClosed(@NonNull View drawerView) {
}
});
}
}
侧边栏样式四(仿QQ 5.0.0)
样式四与样式三差不多,只是onDrawerSlide里面跑的逻辑不一样
// 滑动的过程中执行 slideOffset:从0到1
//主页内容
View content = drawerLayout.getChildAt(0);
//侧边栏
View menu = drawerView;
//
float scale = 1 - slideOffset;//1~0
float leftScale = (float) (1 - 0.3 * scale);
float rightScale = (float) (0.7f + 0.3 * scale);//0.7~1
//menu.setScaleX(leftScale);//1~0.7
menu.setScaleY(leftScale);//1~0.7
//content.setScaleX(rightScale);
content.setScaleY(rightScale);
content.setTranslationX(menu.getMeasuredWidth() * slideOffset);//0~width
Log.d(TAG, "slideOffset=" + slideOffset + ",leftScale=" + leftScale + ",rightScale=" + rightScale);
侧边栏样式五(仿QQ 8.0.0)
样式五其实跟样式三差不多,它只是侧边栏全部铺满屏幕,这个时候侧边栏设置为match_parent仍然无法铺满屏幕。
View leftMenu = findViewById(R.id.menu_frame);
//获取侧边栏默认宽度
ViewGroup.LayoutParams leftParams = leftMenu.getLayoutParams();
//获取屏幕宽度
final int width = ScreenInfoUtils.getWindowWidth(this);
//获取屏幕高度
final int height = ScreenInfoUtils.getFullActivityHeight(this);
//设置侧边的宽高(如果不重新设置,即时设置match_parent也只能占屏幕百分80)
leftParams.width = width;
leftParams.height = FrameLayout.LayoutParams.MATCH_PARENT;
leftMenu.setLayoutParams(leftParams);
这个时候我们可以将侧边视图的宽高设置为屏幕的宽高,就可以解决这个问题。
总结
这些都是平常玩Android应用所看到的侧边栏,全部总结在这里,如果以后还看到其他类型的侧边栏再做补充。
