android控件之NavigationView

1.引入依赖

implementation 'com.android.support:design:27.1.1'

2.准备menu(nav_menu.xml)和headerLayout(nav_header.xml)

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
        <item android:id="@+id/nav_call"
            android:icon="@mipmap/ic_launcher"
            android:title="Call"/>
        <item android:id="@+id/nav_friedns"
            android:icon="@mipmap/ic_launcher"
            android:title="Friends"/>
        <item android:id="@+id/nav_location"
            android:icon="@mipmap/ic_launcher"
            android:title="Location"/>
        <item android:id="@+id/nav_mail"
            android:icon="@mipmap/ic_launcher"
            android:title="Mail"/>
        <item android:id="@+id/nav_task"
            android:icon="@mipmap/ic_launcher"
            android:title="Tasks"/>
    </group>
</menu>

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="180dp"
    android:padding="10dp"
    android:background="?attr/colorPrimary">
    <ImageView
        android:id="@+id/icon_image"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>
    <TextView
        android:id="@+id/username"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="tonygreed"
        android:textColor="#fff"
        android:textSize="14sp"/>
    <TextView
        android:id="@+id/mail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@id/username"
        android:text="Tony Green"
        android:textColor="#fff"
        android:textSize="14sp"/>
</RelativeLayout>

3.主布局

<android.support.v4.widget.DrawerLayout 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:id="@+id/drawer_layout"
    android:background="#fff">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
    </FrameLayout>
    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/nav_menu"
        app:headerLayout="@layout/nav_header"/>
</android.support.v4.widget.DrawerLayout>

4.代码

public class NavigationViewActivity extends AppCompatActivity {
    private DrawerLayout mDrawerLayout;
    private NavigationView navigationView;
    private Toolbar toolbar;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.navigationview_activity);
        toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        mDrawerLayout = findViewById(R.id.drawer_layout);
        navigationView = findViewById(R.id.nav_view);
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            //显示导航按钮
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeAsUpIndicator(R.mipmap.ic_launcher);
        }
        navigationView.setCheckedItem(R.id.nav_call);
        navigationView.setNavigationItemSelectedListener(
                new NavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                        mDrawerLayout.closeDrawers();
                        return true;
                    }
                });
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                //打开
                mDrawerLayout.openDrawer(Gravity.START);
                break;
        }
        return true;
    }
}
