NavigationView를 추가하는 방법

NavigationView를 사용하려면 비고 섹션에 설명 된대로 build.gradle 파일에 종속성을 추가하기 build.gradle 됩니다.

그런 다음 레이아웃에 NavigationView 를 추가합니다.

res/layout/content_main.xml 데모 용 활동의 실제 내용입니다. 여기서는 일반적인 레이아웃 xml을 넣을 것입니다.

        </menu>
    </item>

</menu>

그리고 마지막으로 java/main/eu/rekisoft/playground/MainActivity.java :

public class MainActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

    @Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    @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;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @SuppressWarnings("StatementWithEmptyBody")
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        switch(item.getItemId()) {/*...*/}

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }
}

다음과 같이 보입니다.

메뉴 요소에 밑줄 추가

각 그룹은 줄 구분 기호로 끝납니다. 메뉴의 각 항목에 고유 한 그룹이 있으면 원하는 그래픽 출력을 얻을 수 있습니다. 다른 그룹에 다른 android:id 가 다른 경우에만 작동합니다. 또한, menu.xml 에서 단일 항목의 android:checkable="true" 를 언급하고 항목 그룹의 경우 android:checkableBehavior="single" 을 android:checkableBehavior="single" 해야합니다.

<?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
          android:id="@+id/pos_item_help"
          android:checkable="true"
          android:title="Help" />
     <item
        android:id="@+id/pos_item_pos"
        android:checkable="true"
        android:title="POS" />

    <item
        android:id="@+id/pos_item_orders"
        android:checkable="true"
        android:title="Orders" />

       <group
            android:id="@+id/group"
            android:checkableBehavior="single">
            
                <item
                android:id="@+id/menu_nav_home"
                android:icon="@drawable/ic_home_black_24dp"
                android:title="@string/menu_nav_home" />
        </group>
    
    ......
    </menu>

메뉴에 분리 기호 추가

NavigationView 에서 RecyclerView 에 액세스하고 ItemDecoration 을 추가하십시오.

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
NavigationMenuView navMenuView = (NavigationMenuView) navigationView.getChildAt(0);
navMenuView.addItemDecoration(new DividerItemDecoration(this));

DividerItemDecoration의 코드

public class DividerItemDecoration extends RecyclerView.ItemDecoration {

    private static final int[] ATTRS = new int[]{android.R.attr.listDivider};

    private Drawable mDivider;

    public DividerItemDecoration(Context context) {
        final TypedArray styledAttributes = context.obtainStyledAttributes(ATTRS);
        mDivider = styledAttributes.getDrawable(0);
        styledAttributes.recycle();
    }


    @Override
    public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
        int left = parent.getPaddingLeft();
        int right = parent.getWidth() - parent.getPaddingRight();

        int childCount = parent.getChildCount();
        for (int i = 1; i < childCount; i++) {
            View child = parent.getChildAt(i);

            RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();

            int top = child.getBottom() + params.bottomMargin;
            int bottom = top + mDivider.getIntrinsicHeight();

            mDivider.setBounds(left, top, right, bottom);
            mDivider.draw(c);
        }
    }
}

시사:

기본 메뉴 인 DividerItemDecoration을 사용하여 메뉴를 추가합니다.

그냥 기본 DividerItemDecoration 클래스를 사용하십시오 :

NavigationView navigationView = (NavigationView) findViewById(R.id.navigation);
NavigationMenuView navMenuView = (NavigationMenuView) navigationView.getChildAt(0);
navMenuView.addItemDecoration(new DividerItemDecoration(context,DividerItemDecoration.VERTICAL));
