MyCustomBaseAdapter.java 內容如下

package sample.multilineslist;

import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class MyCustomBaseAdapter extends BaseAdapter {

private static ArrayList<SearchResults> searchArrayList;

private LayoutInflater mInflater;

public MyCustomBaseAdapter(Context context, ArrayList<SearchResults> results) {

searchArrayList = results;
mInflater = LayoutInflater.from(context);
}

public int getCount() {
return searchArrayList.size();
}

public Object getItem(int position) {
return searchArrayList.get(position);
}

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

public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;

if (convertView == null) {
  convertView = mInflater.inflate(R.layout.custom_row_view, null);
  holder = new ViewHolder();
  holder.txtName = (TextView) convertView.findViewById(R.id.name);
  holder.txtBarcode = (TextView) convertView.findViewById(R.id.barcode);
  holder.txtLocation = (TextView) convertView.findViewById(R.id.location);
  convertView.setTag(holder);
  } else {
  holder = (ViewHolder) convertView.getTag();
  }

  holder.txtName.setText(searchArrayList.get(position).getName());
  holder.txtBarcode.setText(searchArrayList.get(position).getBarcode());
  holder.txtLocation.setText(searchArrayList.get(position).getLocation());
  return convertView;
}

static class ViewHolder {
  TextView txtName;
  TextView txtBarcode;
  TextView txtLocation;
}
}

SearchResults.java  內容如下:

package sample.multilineslist;

public class SearchResults {
private String name = "";
private String barcode = "";
private String location = "";

public void setName(String name) {
  this.name = name;
}

public String getName() {
  return name;
}

public void setBarcode(String barcode) {
  this.barcode = barcode;
}

public String getBarcode() {
  return barcode;
}

public void setLocation(String location) {
  this.location = location;
}

public String getLocation() {
  return location;
}
}

在 res/layout 下加入以下檔案
custom_row_view.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

  <TextView android:id="@+id/name"
  android:textSize="18sp"
  android:textStyle="bold"
  android:textColor="#FFFF00"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"/>

<TextView android:id="@+id/barcode"
  android:textSize="16sp"
  android:textStyle="normal"
  android:textColor="#5BEF8C"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"/>

<TextView android:id="@+id/location"
