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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | <?xml version= "1.0" encoding= "utf-8" ?> <android.support.v4.widget.DrawerLayout xmlns:android= "http://schemas.android.com/apk/res/android" 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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | <?xml version= "1.0" encoding= "utf-8" ?> <!--学生左滑后界面--> <android.support.constraint.ConstraintLayout android:layout_width= "match_parent" android:layout_height= "match_parent" > 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | <?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/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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 | 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)
