Android studio有关侧滑的实现代码
时间:2022-06-28 09:18:17|栏目:Android代码|点击: 次
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: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)
