Android中DrawerLayout实现侧滑菜单效果
众所周知,android里面我们很熟悉的一个功能,侧滑菜单效果在以前我们大部分都是用的slidingmenu这个开源框架,自从谷歌官方新出的一个DrawerLayout控件之后,越来越多的应用开始使用谷歌的官方的控件写这个效果了。
话不多说,先来发图以表我滴诚意:
开始写代码
DrawerLayout 是v4包里面的,所以项目里面需要添加v4包,具体怎么添加就不多说了,
NavigationView需要在build.gradle里面添加compile ‘com.android.support:design:25.1.0'
activity_main.xml
<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"> <!-- 右边视图 --> <include layout="@layout/app_bar_main" android:layout_width="match_parent" android:layout_height="match_parent" /> <!-- 左边菜单 --> <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_main" app:menu="@menu/activity_main_drawer" /> </android.support.v4.widget.DrawerLayout>
然后在res文件夹里面添加一个menu菜单文件夹,已经添加的就不用添加了
上面的代码里面NavigationView里面有个 app:menu=”@menu/activity_main_drawer”对应如下:
添加一个菜单文件,名字随意,我的是activity_main_drawer.xml
activity_main_drawer.xml
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <group android:checkableBehavior="single"> <item android:id="@+id/nav_camera" android:icon="@drawable/ic_menu_camera" android:title="第一行" /> <item android:id="@+id/nav_gallery" android:icon="@drawable/ic_menu_gallery" android:title="第二行" /> <item android:id="@+id/nav_slideshow" android:icon="@drawable/ic_menu_slideshow" android:title="第三行" /> <item android:id="@+id/nav_manage" android:icon="@drawable/ic_menu_manage" android:title="第四行" /> </group> <item android:title="Communicate"> <menu> <item android:id="@+id/nav_share" android:icon="@drawable/ic_menu_share" android:title="第五行" /> <item android:id="@+id/nav_send" android:icon="@drawable/ic_menu_send" android:title="第六行" /> </menu> </item> </menu>
再添加一个布局
上面的代码里面app:headerLayout=”@layout/nav_header_main”对应如下:
添加一个布局,名字是nav_header_main.xml
nav_header_main.xml
<?xml version="1.0" encoding="utf-8"?> <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_height="@dimen/nav_header_height" android:background="@drawable/side_nav_bar" android:gravity="bottom" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:theme="@style/ThemeOverlay.AppCompat.Dark"> <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="@dimen/nav_header_vertical_spacing" app:srcCompat="@android:drawable/sym_def_app_icon" /> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:paddingTop="@dimen/nav_header_vertical_spacing" android:text="哈哈哈" android:textAppearance="@style/TextAppearance.AppCompat.Body1" /> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="123456789@qq.com" /> </LinearLayout>
MainActivity:
public class MainActivity extends BaseActivity implements NavigationView.OnNavigationItemSelectedListener { private LinearLayout right; private NavigationView left; private boolean isDrawer=false; private DrawerLayout drawer; @Override public int getLayoutId() { return R.layout.activity_main; } @Override public void initPresenter() { } @Override public void initView() { drawer = (DrawerLayout) findViewById(R.id.drawer_layout); right = (LinearLayout) findViewById(R.id.right); left = (NavigationView) findViewById(R.id.nav_view); NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); right.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View view, MotionEvent motionEvent) { if(isDrawer){ return left.dispatchTouchEvent(motionEvent); }else{ return false; } } }); drawer.setDrawerListener(new DrawerLayout.DrawerListener() { @Override public void onDrawerSlide(View drawerView, float slideOffset) { isDrawer=true; //获取屏幕的宽高 WindowManager manager = (WindowManager) getSystemService(Context.WINDOW_SERVICE); Display display = manager.getDefaultDisplay(); //设置右面的布局位置 根据左面菜单的right作为右面布局的left 左面的right+屏幕的宽度(或者right的宽度这里是相等的)为右面布局的right right.layout(left.getRight(), 0, left.getRight() + display.getWidth(), display.getHeight()); } @Override public void onDrawerOpened(View drawerView) {} @Override public void onDrawerClosed(View drawerView) { isDrawer=false; } @Override public void onDrawerStateChanged(int newState) {} }); } @Override public void onBackPressed() { if (drawer.isDrawerOpen(GravityCompat.START)) { drawer.closeDrawer(GravityCompat.START); } else { super.onBackPressed(); } } @SuppressWarnings("StatementWithEmptyBody") @Override public boolean onNavigationItemSelected(MenuItem item) { // Handle navigation view item clicks here. int id = item.getItemId(); if (id == R.id.nav_camera) { // Handle the camera action } else if (id == R.id.nav_gallery) { } else if (id == R.id.nav_slideshow) { } else if (id == R.id.nav_manage) { } else if (id == R.id.nav_share) { } else if (id == R.id.nav_send) { } DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); drawer.closeDrawer(GravityCompat.START); return true; }
drawer.openDrawer(GravityCompat.START);//打开滑动菜单
drawer.closeDrawer(GravityCompat.START);//关闭滑动菜单
drawer.isDrawerOpen(GravityCompat.START);//判断滑动菜单是否打开
