關于ListView的作業

原生布局并未多做修改

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.kimdemon.listview.MainActivity"><ListViewandroid:id="@+id/yf_list"android:layout_width="match_parent"android:layout_height="wrap_content"></ListView>
</LinearLayout>

另外在新建一個LIstView的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><LinearLayoutandroid:layout_width="3dp"android:layout_height="wrap_content"android:orientation="vertical"android:layout_weight="0"></LinearLayout><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"></LinearLayout><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/TextView1"android:id="@+id/yf_name"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/TextView2"android:id="@+id/yf_age"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/TextView3"android:id="@+id/yf_com"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"style="@style/TextView4"android:id="@+id/yf_address"/>
</LinearLayout>

Java中，對于清單的定義

package com.example.kimdemon.listview;public class Infomation {
private String yf_name;private int yf_age;private String yf_com;private String yf_address;public Infomation(String yf_name,String yf_com,String yf_address,int yf_age){this.yf_name = yf_name;this.yf_age = yf_age;this.yf_com = yf_com;this.yf_address = yf_address;}public String getYf_name(){return yf_name;}public void setYf_name(String yf_name){this.yf_name = yf_name;}public int getYf_age(){return yf_age;}public void setYf_age(int yf_age){this.yf_age = yf_age;}public String getYf_com(){return yf_com;}public void setYf_com(String yf_com){this.yf_name = yf_com;}public String getYf_address(){return yf_address;}public void setYf_address(String yf_address){this.yf_address = yf_address;}
}

ListView的部分定義

package com.example.kimdemon.listview;import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;import java.util.List;public class listview extends BaseAdapter {
private List<Infomation> info;
private Context context;public listview(Context context,List info){
this.info = info;
this.context = context;
}
@Override
public int getCount(){return info.size();
}
public Object getItem(int i){return info.get(i);
}
public long getItemId(int i){return i;
}public View getView(int i, View view, ViewGroup viewGroup){GiveWith with = null;with = new GiveWith();view = LayoutInflater.from(context).inflate(R.layout.listview,null);with.yf_name = (TextView) view.findViewById(R.id.yf_name);with.yf_age = (TextView) view.findViewById(R.id.yf_age);with.yf_com = (TextView) view.findViewById(R.id.yf_com);with.yf_address = (TextView) view.findViewById(R.id.yf_address);Infomation infomation = info.get(i);with.yf_name.setText(infomation.getYf_name());with.yf_age.setText(infomation.getYf_age());with.yf_com.setText(infomation.getYf_com());with.yf_address.setText(infomation.getYf_address());return view;
}class GiveWith{TextView yf_name;TextView yf_age;TextView yf_com;TextView yf_address;
}}

原生Java的代碼則是

package com.example.kimdemon.listview;import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ListView;import java.util.ArrayList;public class MainActivity extends AppCompatActivity {
private listview listViewit;@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ArrayList<Infomation> info = getInfomation();listViewit = new listview(MainActivity.this,info);ListView listView = (ListView)findViewById(R.id.yf_list);listView.setAdapter(listViewit);
}
public ArrayList<Infomation> getInfomation(){ArrayList<Infomation> info = new ArrayList<>();info.add(new Infomation("李易峰","未知","北京",29));info.add(new Infomation("楊洋","未知","北京",26));info.add(new Infomation("司南","未知","未知",20));info.add(new Infomation("顏真","未知","未知",20));return info;
}
}
