Android仿QQ个人界面，抽屉布局 NavigationView使用详解

NavigationView，导航视图，比如QQ的侧滑菜单，如下图，分为head和menu上下两部分head【图片，昵称，uid】menu【下面的菜单】

添加implementation 'com.android.support:design:29.+'

圆形头像CircleImageView或者是

//实现图片圆形化

compile 'de.hdodenhof:circleimageview:2.1.0'2.

res目录下values创建添加

<declare-styleable name="CircleImageView">
    <attr name="civ_border_width" format="dimension" />
    <attr name="civ_border_color" format="color" />
    <attr name="civ_border_overlay" format="boolean" />
    <attr name="civ_fill_color" format="color" />
</declare-styleable>

实现：

主页布局


<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.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:orientation="vertical"
    tools:context=".activity.MainActivity">
 
 
    <!--可以在程序中根据抽屉菜单 切换Fragment-->
 
 
        <FrameLayout
            android:id="@+id/frame_layout"

    <!--左边抽屉菜单宽高什么的可以自己调-->
    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nv_menu_left"
        android:layout_width="140dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        app:headerLayout="@layout/header"
        app:menu="@menu/menu_drawer_left" />
 
 
</androidx.drawerlayout.widget.DrawerLayout>

NavitationView常用属性

android:layout_gravity="left"设置在哪边划出
app:headerLayout="@layout/header"设置布局的文件头，此案例是那个圆形头像，昵称和uid
app:menu="@menu/menu_drawer_left"设置点击项，就是档案馆那三个

header布局

<?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="240dp"
    android:background="@mipmap/ic_app_top_bg"
    android:orientation="vertical">

    <CircleImageView
        android:layout_width="@dimen/dp_90"
        android:id="@+id/cv_user_head"
        android:layout_height="@dimen/dp_90"
        android:layout_marginLeft="@dimen/dp_20"
        android:layout_marginTop="36dp"
        android:layout_marginBottom="16dp"

        android:orientation="horizontal">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="木偶MUO："
            android:textColor="@color/color_212121"
            android:textSize="@dimen/sp_12" />

        <TextView
            android:id="@+id/tv_user_uuid"
            android:layout_width="wrap_content"

            android:textSize="@dimen/sp_12" />
    </LinearLayout>

</LinearLayout>

menu_drawer_left布局【res目录下创建menu目录下创建menu_drawer_left布局】

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/nav_home"
        android:icon="@mipmap/ic_app"
        android:title="关于我们" />
    <item
        android:id="@+id/nav_messages"
        android:icon="@mipmap/ic_fun"
        android:title="反馈" />
    <item
        android:id="@+id/nav_friends"
        android:icon="@mipmap/ic_muo"
        android:title="档案馆" />

</menu>

java代码

public class MainActivity extends BaseActivity {

@BindView(R.id.nv_menu_left)
NavigationView nvMenuLeft;
@BindView(R.id.drawer_layout)
DrawerLayout drawerLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//实例化的NavigationView控件
nvMenuLeft.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {

case R.id.nav_home:
startActivity(new Intent(MainActivity.this, AboutActivity.class));
break;
case R.id.nav_messages:
startActivity(new Intent(MainActivity.this, IdearActivity.class));
break;
case R.id.nav_friends:
startActivity(new Intent(MainActivity.this, TextImgActivity.class));
break;
}
drawerLayout.closeDrawers();
return false;
}
});

}

//抽屉布局的左侧头部初始化控件
TextView mUserUid;
LinearLayout llCopyUid;
TextView mUserName;
CircleImageView mUserAvatar;

private void initUserInfo() {
// 获取头部视图
View headerView = nvMenuLeft.getHeaderView(0);
//头部初始化控件
mUserAvatar = headerView.findViewById(R.id.cv_user_head);
mUserName = headerView.findViewById(R.id.tv_user_name);
mUserUid = headerView.findViewById(R.id.tv_user_uuid);
llCopyUid = headerView.findViewById(R.id.ll_copy_uid);
mUserUid.setText(StringCache.get("uid"));
//点击事件
mUserAvatar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//关闭抽屉布局
drawerLayout.closeDrawers();
//打开布局，参数Gravity.LEFTGravity.LEFT to move the left drawer or Gravity.RIGHT for the right.
// GravityCompat.START or GravityCompat.END may also be used.
// drawerLayout.openDrawer(Gravity.LEFT);
}
});

//头像展示
Glide.with(MainActivity.this).load(R.mipmap.ic_app).apply(RequestOptions.circleCropTransform()).into(mUserAvatar);
}

}
}

大致的功能基本都在这边了，下面就是自己的逻辑实现了，应该是很明了的一篇文章了，后续需要的话可以继续补充功能
