Android studio有关侧滑的实现代码

最近写课设，因为是新手，实现起来比较麻烦。所以写下此笔记，免得我以后忘记了。

附图片：

//主页面的布局activity_main.xml:

<?xml version='1.0' encoding='utf-8'?><android.support.v4.widget.DrawerLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' xmlns:qpp='http://schemas.android.com/apk/res-auto' android: android:layout_width='match_parent' android:layout_height='match_parent' android:fitsSystemWindows='true' tools:openDrawer='start'> <TextView android:layout_width='wrap_content' android:layout_height='wrap_content' android:text='Hello World!' /> <android.support.design.widget.NavigationView android: android:layout_width='207dp' android:layout_height='match_parent' android:layout_gravity='left' android:fitsSystemWindows='true' qpp:headerLayout='@layout/stumenu1' qpp:menu='@menu/stumenu1' /></android.support.v4.widget.DrawerLayout>

头部的布局（放入layout）stumenu1.xml:

<?xml version='1.0' encoding='utf-8'?><!--学生左滑后界面--><android.support.constraint.ConstraintLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' android:layout_width='match_parent' android:layout_height='match_parent'> <LinearLayout xmlns:android='http://schemas.android.com/apk/res/android' android:orientation='vertical' android:layout_width='match_parent' android:layout_height='match_parent' android:gravity='center' > <ImageView android: android:layout_width='72dp' android:layout_height='72dp' android:layout_marginTop='75dp' android:src='https://www.haobala.com/bcjs/@drawable/student' /> <TextView android: android:layout_width='wrap_content' android:layout_height='wrap_content' android:textSize='20sp' android:layout_marginTop='20dp' android:textColor='#282525' android:text='测试APP'/> </LinearLayout></android.support.constraint.ConstraintLayout>

菜单的布局：(放在menu文件夹）stumenu1

<?xml version='1.0' encoding='utf-8'?><menu xmlns:android='http://schemas.android.com/apk/res/android' xmlns:app='http://schemas.android.com/apk/res-auto'> <group android:checkableBehavior='single'> <item android: android:icon='@drawable/ic_launcher_background' android:checkable='true' android:title=' 测试结果'/> <item android: android:icon='@drawable/ic_launcher_background' android:title=' 错题'/> <item android: android:icon='@drawable/ic_launcher_background' android:title=' 得分'/> <item android: android:icon='@drawable/ic_launcher_background' android:title=' 退出'/> </group></menu>

MainActivity.java:

package com.example.cholewu.slide;import android.content.Intent;import android.support.annotation.NonNull;import android.support.design.widget.NavigationView;import android.support.v4.widget.DrawerLayout;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.MenuItem;import android.widget.Toast;public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //左滑菜单 initView(); } private void initView() { //实现左右滑动 final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); //菜单控件 final NavigationView nv = findViewById(R.id.nav_view); nv.setItemIconTintList(null);nv.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { @Override public boolean onNavigationItemSelected(@NonNull MenuItem item) {switch (item.getItemId()){ case R.id.exit: //跳转到退出页面 Toast.makeText(MainActivity.this,'你已退出登录！',Toast.LENGTH_SHORT).show(); Intent intent=new Intent(); intent.setClass(MainActivity.this,Exit.class); startActivity(intent); item.setChecked(true); break;}item.setCheckable(true);//设置可选项item.setChecked(true);//设置被选中drawer.closeDrawers();//关闭菜单栏return true; } }); }}

(注意：如果直接复制代码的话，android.support.design.widget.NavigationView可能会出错，需要自己在design那里布局，如果出错，可以看看以下NavigationView右边是否有下载图案，点击下载就行了）
