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。

Android studio有关侧滑的实现代码

//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:id="@+id/drawer_layout"
  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:id="@+id/nav_view"
    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:id="@+id/person"
      android:layout_width="72dp"
      android:layout_height="72dp"
      android:layout_marginTop="75dp"
      android:src="@drawable/student"
      />
    <TextView
      android:id="@+id/stutv"
      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:id="@+id/result"
      android:icon="@drawable/ic_launcher_background"
      android:checkable="true"
      android:title=" 测试结果"/>

  <item
    android:id="@+id/w1"
    android:icon="@drawable/ic_launcher_background"

    android:title=" 错题"/>
  <item
    android:id="@+id/s1"
    android:icon="@drawable/ic_launcher_background"
    android:title=" 得分"/>

  <item
    android:id="@+id/exit"
    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)
