本文主要是介绍simpleApater自定义列表(程序),对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

1、新创建一个XML文件,存放列表

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
    <ListView
            android:id="@+id/simpleAdaperbtnzdydy"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"/>
</LinearLayout>

2、新创建一个一个XML文件存放列表内容

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
    <ImageView
            android:id="@+id/imgeviewzdy"
            android:layout_width="60dp"
            android:layout_height="60dp"




            />


    <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_marginLeft="10dp"


            >
        <TextView
                android:id="@+id/simpletextonezdy"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="@color/red"
                android:text="title"
                android:textSize="18dp"
                />
        <TextView
                android:id="@+id/simpletexttwozdy"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="info"
                />
    </LinearLayout>
</LinearLayout>

3、创建一个java源文件

package com.example.jj;


import android.app.Activity;
import android.os.Bundle;




import android.util.Log;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
import org.w3c.dom.Text;




import java.util.ArrayList;
import java.util.List;


/**
 * Created by Administrator on 14-11-24.
 */
public class SimpleApaterZdy extends Activity {
    private ListView listViewzdy;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.simpleadaper2);

//获取XML文件中存放列表listview 中id名
        listViewzdy = (ListView) findViewById(R.id.simpleAdaperbtnzdydy);

//获取MyBaseAdapter的数据,MyBaseAdapter是新建另一个java文件
        MyBaseAdapter adapter = new MyBaseAdapter(this,getData());
        listViewzdy.setAdapter(adapter);


    }

------------------------------------------------------------------------------------------------------------------------------------------------------

Massage外部类

package com.example.jj;


/**
 * Created by Administrator on 14-11-24.
 */
public class Massages {


    private int id;
    private String title;
    private String content;
    private int headerIcon;


    public int getId() {
        return id;
    }


    public void setId(int id) {
        this.id = id;
    }


    public String getTitle() {
        return title;
    }


    public void setTitle(String title) {
        this.title = title;
    }


    public String getContent() {
        return content;
    }


    public void setContent(String content) {
        this.content = content;
    }


    public int getHeaderIcon() {
        return headerIcon;
    }


    public void setHeaderIcon(int headerIcon) {
        this.headerIcon = headerIcon;
    }
}


----------------------------------------------------------------------------------------------------------------------------------------------------------

//获取Massges外部类(也可以内部类实现)
    public List<Massages> getData() {
        List<Massages> list = new ArrayList<Massages>();

//new一个massage,装要在XML中展示的内容
        Massages msg = new Massages();
        msg.setId(10);//获取ID
        msg.setTitle("发vbwqrfvqfvqv去");
        msg.setHeaderIcon(R.drawable.tubiao);//获取图标
        msg.setContent("contet111111");获取内容


        Massages msg1 = new Massages();
        msg1.setId(11);
        msg1.setTitle("发vbwqrfvqfvqv去1111");
        msg1.setHeaderIcon(R.drawable.a);
        msg.setContent("conte222");


        Massages msg2 = new Massages();
        msg2.setId(12);
        msg2.setTitle("发vbwqrfvqfvqv去222221");
        msg2.setHeaderIcon(R.drawable.c);
        msg.setContent("contet23333");


        list.add(msg);
        list.add(msg1);
        list.add(msg2);
        return list;
    }


}

4、新建一个java文件实现它的四种方法,对XML中的插件做初始化处理

package com.example.jj;


import android.content.Context;
import android.os.Message;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;


import java.util.ArrayList;
import java.util.List;


/**
 * Created by Administrator on 14-11-24.
 */
public class MyBaseAdapter extends BaseAdapter {
    private List<Massages> mList=new ArrayList<Massages>();
    private LayoutInflater mInflater;
     private Context mcontext;
    public MyBaseAdapter(Context context, List<Massages> list) {
        mcontext=context;


        mInflater = LayoutInflater.from(mcontext);
        mList = list;


    }
//实现方法

    @Override
    public int getCount() {
        return mList.size();
    }


    @Override
    public Object getItem(int position) {
        return mList.get(position);
    }


    @Override
    public long getItemId(int position) {
        return position;
    }

//初始化XML文件里各插件的值
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = mInflater.inflate(R.layout.simpleapaterzdy, null);
        ImageView iconImg = (ImageView) view.findViewById(R.id.imgeviewzdy);
        TextView titleTxt = (TextView) view.findViewById(R.id.simpletextonezdy);
        TextView infoTxt = (TextView) view.findViewById(R.id.simpletexttwozdy);


        Massages msg = (Massages) getItem(position);
        iconImg.setImageResource(msg.getHeaderIcon());
        titleTxt.setText(msg.getTitle());
        infoTxt.setText(msg.getContent());
        return view;
    }
}
