类似于这种效果

讯享网

1,新建一个Student类,用户添加学生信息

private int icon; private String name; private int age; private String sex ; private int id; public Student(int icon, String name, int age, String sex, int id) { this.icon = icon; this.name = name; this.age = age; this.sex = sex; this.id = id; } //下面添加getter and setter方法

2,主布局文件中添加ListView控件

讯享网<ListView android:id="@+id/act_base_adapter_student_lv" android:layout_width="match_parent" android:layout_height="match_parent"> </ListView>

3.新建一个StudentInfoAdapter类,继承BaseAdapter并且实现其中的抽象方法

public class StudentInfoAdapter extends BaseAdapter { @Override public int getCount() { return 0; } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { return null; } }

4,创建一个item_student.xml布局文件,用于设置列表中单个条目的布局

这种条目布局

讯享网<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal"> <ImageView android:id="@+id/act_item_student_iv" android:layout_width="80dp" android:layout_height="80dp" android:src="@drawable/user_icon" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:padding="10dp"> <TextView android:id="@+id/item_student_name_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/stu_name" /> <TextView android:id="@+id/item_student_age_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:text="@string/stu_age" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:text="@string/stu_sex" /> <TextView android:id="@+id/item_student_id_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentEnd="true" android:text="@string/stu_id" /> </RelativeLayout> </LinearLayout>

5,定义有参构造函数,在StudentInfoAdapter类中重写的getCount()方法中return  传入的list 的长度

private Context mContext; private List<Student> mList public StudentInfoAdapter(Context Context,List<Student> list) { this.mContext = Context; this.mList = list; } @Override public int getCount() { return mList.size(); }

6,StudentInfoAdapter类中重写的getView()方法中设置控件和属性,具体看下面代码注释

讯享网@Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { //将自定义的布局文件设置给convertView convertView = View.inflate(mContext, R.layout.item_student, null); } //获取convertView中要使用的控件 ImageView iconIv = convertView.findViewById(R.id.act_item_student_iv); TextView idTv = convertView.findViewById(R.id.item_student_id_tv); TextView nameTv = convertView.findViewById(R.id.item_student_name_tv); TextView ageTv = convertView.findViewById(R.id.item_student_age_tv); TextView sexTv = convertView.findViewById(R.id.item_student_sex_tv); //根据每次调用getView方法时的position值获取当前需要填充的Student对象 Student student = mList.get(position); //将此Student对象的各个属性设置给item中的相关控件 iconIv.setImageResource(student.getIcon()); nameTv.setText("姓名:"+student.getName()); idTv.setText("座号:"+ student.getId()); ageTv.setText("年龄:"+student.getAge()); sexTv.setText("性别:"+student.getSex()); return convertView; }

7,在主类中初始化

 private ListView studentLv; private ArrayList<Student> stuAl; private StudentInfoAdapter adapter; //学生ListView studentLv = findViewById(R.id.act_base_adapter_student_lv); stuAl = new ArrayList<>(); //初始化自定义的StudentInfoAdapter if (adapter == null) { adapter = new StudentInfoAdapter(this, stuAl); }else{ adapter.notifyDataSetChanged(); } 

8,添加学生信息

讯享网 stuAl.add(new Student(R.drawable.stu1,"露娜",11,"女",1)); stuAl.add(new Student(R.drawable.stu2,"王昭君",13,"女",2)); stuAl.add(new Student(R.drawable.stu3,"貂蝉",17,"女",3)); stuAl.add(new Student(R.drawable.stu4,"兰陵王",18,"男",4)); stuAl.add(new Student(R.drawable.stu7,"李白",16,"男",5)); stuAl.add(new Student(R.drawable.stu6,"鲁班",19,"男",6)); stuAl.add(new Student(R.drawable.stu8,"狄仁杰",15,"男",7)); stuAl.add(new Student(R.drawable.stu9,"武则天",10,"女",8)); stuAl.add(new Student(R.drawable.stu10,"妲己",14,"女",9));

9,给设置适配器

studentLv.setAdapter(adapter);

10,添加功能:点击学生条目,谈提示框提示学生信息,如下效果

添加条目点击监听器,然后添加对话框

讯享网 studentLv.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Student student = stuAl.get(position); String nameStr = student.getName(); int age = student.getAge(); int idInt = student.getId(); String sexStr = student.getSex(); AlertDialog.Builder builder = new AlertDialog.Builder(BaseAdapterActivity.this); builder.setTitle("学生信息"); builder.setMessage("姓名:"+nameStr+ "\r\n年龄:"+age+ "\r\n性别:"+sexStr+ "\r\n座 号:"+idInt); builder.setPositiveButton("知道了", null); builder.create().show(); } });
