Android Material Design 控件 NavigationView

1 开始使用

compile 'com.android.support:design:25.3.1'

2 滑动菜单不覆盖Toolbar

 <LinearLayout 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_width="match_parent"
            android:layout_height="match_parent" >

            <TextView
                android:padding="16dp"

                android:layout_height="match_parent" />
                
        </FrameLayout>

        <!-- 侧滑布局 -->
        <android.support.design.widget.NavigationView
            android:id="@+id/id_navigation_view"
            android:layout_width="wrap_content"

    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

             android:layout_height="match_parent"
             android:background="@color/colorPrimary"
             android:orientation="vertical">

3 配合Toolbar左侧按钮

• 设置

  DrawerLayout drawer = (DrawerLayout) findViewById(R.id.id_drawer_layout);
        //左侧按钮 旋转
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer,
                toolbar,
                R.string.openDrawerContentDesc, R.string.closeDrawerContentDesc);
        drawer.addDrawerListener(toggle);
        toggle.syncState();//同步状态

• 不设置

     ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer,
                R.string.openDrawerContentDesc, R.string.closeDrawerContentDesc);

4 滑动菜单覆盖Toolbar

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    android:id="@+id/id_drawer_layout"
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:openDrawer="start">

   <LinearLayout
            android:id="@+id/id_ll_content"
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
   <android.support.v7.widget.Toolbar
        android:id="@+id/id_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        />
            <TextView
                android:padding="16dp"
                android:text="test"
                android:gravity="center"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:weight="1"
                />
                
        </LinearLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_drawer_layout__one"
        app:menu="@menu/activity_drawer_layout__one_drawer"/>

</android.support.v4.widget.DrawerLayout>

5 监听菜单点击

 nv_menu_left.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.navigation_item1:
                        mToolBar.setTitle("选项一");
                        break;
                    case R.id.navigation_item2:
                        mToolBar.setTitle("选项二");
                        break;
                    case R.id.navigation_item3:
                        mToolBar.setTitle("选项三");
                        break;
                    case R.id.navigation_sub_item1:
                        mToolBar.setTitle("简介");
                        break;
                    case R.id.navigation_sub_item2:
                        mToolBar.setTitle("详情");
                        break;
                    case R.id.navigation_sub_item3:
                        mToolBar.setTitle("更多");
                        break;
                }

               //选中的条件是该menu的checkable为true
                item.setCheckable(true);
                //将选中设为文字选中的状态
                //item.setChecked(true);
                //
                //id_navigation_view.setCheckedItem(item.getItemId());
                //关闭抽屉
                mDrawerLayout.closeDrawers();
                return true;
            }
        });

6 菜单样式相关

• 让菜单图片显示原来的颜色

app:itemIconTint=""

//或者

mNavigationView.setItemIconTintList(null);

• 菜单过多，隐藏滚动条

NavigationMenuView menuView  = (NavigationMenuView) mNavigationView.getChildAt(0);
menuView.setVerticalScrollBarEnabled(false);

• 样式自定义

菜单item背景
 app:itemBackground
 
菜单item文字颜色
app:itemTextColor

文字样式
app:itemTextAppearance

• 默认选中菜单

menu xml 设置

android:checked="true"

• 默认选中菜单（带背景）
  方法1
  menu xml 设置

android:checkable="true"

代码中 设置

 //设置默认选中 选中的条件是该menu的checkable为true
         id_navigation_view.setCheckedItem(R.id.id_menu_item_patient_list);

方法2
代码中 设置

        //设置默认选中
        if (id_navigation_view.getMenu()!=null&&id_navigation_view.getMenu().size()>0){
            mMenuItem=id_navigation_view.getMenu().getItem(0);
            mMenuItem.setCheckable(true);
            //选中的条件是该menu的checkable为true
            id_navigation_view.setCheckedItem(mMenuItem.getItemId());
        }

• 动态隐藏菜单

NavigationView.getMenu().findItem(R.id.item_1);
item.setVisible(false);//false即隐藏，true即显示

7 获取head的view

 headerView = mNavigationView.getHeaderView(0);

8 监听侧滑

• onDrawerSlide方法中的slideOffset，则对应于DrawerLayout展开的偏移值，全部展开时为1，全部收起时为0，onDrawerStateChanged对应于所处的状态：STATE_IDLE/STATE_DRAGGING/STATE_SETTLING

  mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {

            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                Log.d("mDrawerLayout", "onDrawerSlide, slideOffset=" + slideOffset);
            }

            @Override
            public void onDrawerOpened(View drawerView) {
                Log.d("mDrawerLayout", "onDrawerOpened");
            }

            @Override
            public void onDrawerClosed(View drawerView) {
                Log.d("mDrawerLayout", "onDrawerClosed");
            }

            @Override
            public void onDrawerStateChanged(int newState) {
                Log.d("mDrawerLayout", "onDrawerStateChanged, state=" + newState);

            }
        });
