建立网络音乐列表适配器NetMusicAdapt.java

package com.haoxue.zixueplayer.adapter;

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 com.haoxue.zixueplayer.R;
import com.haoxue.zixueplayer.vo.SearchResult;

import java.util.ArrayList;

/**
* 网络音乐列表适配器
* Created by Administrator on 2016/7/31.
*/
public class NetMusicAdapter extends BaseAdapter{

private Context ctx;
private ArrayList<SearchResult> searchResults;

public NetMusicAdapter(Context ctx, ArrayList<SearchResult> searchResults) {
this.ctx = ctx;
this.searchResults = searchResults;
}

public ArrayList<SearchResult> getSearchResults() {
return searchResults;
}

public void setSearchResults(ArrayList<SearchResult> searchResults) {
this.searchResults = searchResults;
}

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

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

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vh;
if (convertView == null) {
convertView= LayoutInflater.from(ctx).inflate(R.layout.net_item_music_list,null);
vh=new ViewHolder();
vh.textView1_title= (TextView) convertView.findViewById(R.id.textView1_title);
vh.textView2_singer= (TextView) convertView.findViewById(R.id.textView2_singer);
convertView.setTag(vh);
}
vh= (ViewHolder) convertView.getTag();
SearchResult result=searchResults.get(position);
vh.textView1_title.setText(result.getMusicName());
vh.textView2_singer.setText(result.getArtist());
return convertView;
}

static class ViewHolder{
TextView textView1_title;
TextView textView2_singer;
}
}

net_item_music_list.xml代码如下

<?xml version="1.0" encoding="utf-8"?>

android:orientation="horizontal" android:layout_width="match_parent"

<LinearLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">

<TextView

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>

<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView_xia"
android:src="@mipmap/local_music_more"/>

</LinearLayout>

建立搜索音乐对象实体类SearchResult.java

package com.haoxue.zixueplayer.vo;

/**
* 搜索音乐的对象
* Created by Administrator on 2016/7/31.
*/
public class SearchResult {
private String musicName;
private String url;
private String artist;
private String album;

public String getMusicName() {
return musicName;
}

public void setMusicName(String musicName) {
this.musicName = musicName;
}

public String getUrl() {
return url;
}

public void setUrl(String url) {
this.url = url;
}

public String getArtist() {
return artist;
}

public void setArtist(String artist) {
this.artist = artist;
}

public String getAlbum() {
return album;
}

public void setAlbum(String album) {
this.album = album;
}

@Override
public String toString() {
return "SearchResult{" +
"musicName='" + musicName + '\'' +
", url='" + url + '\'' +
", artist='" + artist + '\'' +
", album='" + album + '\'' +
'}';
}
}
