Question

我最近在youtube上关于如何创建自定义数组适配器的Derek Banas的教程。在适配器代码中，他只为一个文本视图输入了一个字符串数组。我有两个文本视图和两个字符串数组，我已经输入了第一个文本视图的第一个字符串数组，就像在视频中一样，但我该怎么做呢？

以下是Derek Banas的视频教程：https://www.youtube.com/watch?v=rhj4_KBD6BQ&list=UUwRXb5dUK4cvsHbx-rGzSgw

这是我的适配器代码：

class HangarAdapter extends ArrayAdapter<String> {


public HangarAdapter(Context context,String[] values) {
    super(context, R.layout.hangar_layout, values);

}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater theInflater = LayoutInflater.from(getContext());

    View theView = theInflater.inflate(R.layout.hangar_layout, parent, false);

    TextView TextView1 = (TextView) theView.findViewById(R.id.textView1);


    //TextView2 Is the text view i want the second string array to go into
    TextView TextView2 = (TextView) theView.findViewById(R.id.textView2);

    TextView1.setText(getItem(position));

    ImageView theImageView = (ImageView) theView.findViewById(R.id.imageView);

    return theView;
    }

以下是我在活动中设置适配器的方法：

    String[] ship = {"Scout Ship", "Ranger Ship" , "Gun Ship MK.1",
            "Conquerer Ship", "Gun Ship MK.2", "Tank Ship",
            "Battle Ship MK.1", "Titan Ship", "Battle Ship MK.2",
            "Colossal Titan Ship"};

    //shipDesc below is the second string array.
    String[] shipDesc = {"10 Planets Every 5 Secs \n 100$",
            "50 Planets Every 5 Secs \n 500$",
            "100 Planets Every 5 Secs \n 1500$",
            "500 Planets Every 4 Secs \n 3000$",
            "1000 Planets Every 4 Secs \n 7500$",
            "5000 Planets Every 4 Secs \n 15000$",
            "10000 Planets Every 3 Secs \n 50000$",
            "30000 Planets Every 3 Secs \n 100000$",
            "60000 Planets Every 3 Secs \n  500000$",
            "100000 Planets Every 1 Secs \n 1000000$"};

    ListView hangarList = (ListView) findViewById(R.id.hangarList);
    ListAdapter adapter = new HangarAdapter(this, ship);

hangarList.setAdapter(adapter);

Answer 1

不是使用String-array，而是创建一个带有title和description字段的ship类，并制作一个ship-array。

Ship ship = (Ship) getItem(position);
textview1.setText(ship.getTitle());
textView2.setText(ship.getDesc());

Answer 2

由于两个数组都有相同的长度所以这个

class HangarAdapter extends ArrayAdapter<String> {

     //shipDesc below is the second string array.
        String[] shipDesc = {"10 Planets Every 5 Secs \n 100$",
                "50 Planets Every 5 Secs \n 500$",
                "100 Planets Every 5 Secs \n 1500$",
                "500 Planets Every 4 Secs \n 3000$",
                "1000 Planets Every 4 Secs \n 7500$",
                "5000 Planets Every 4 Secs \n 15000$",
                "10000 Planets Every 3 Secs \n 50000$",
                "30000 Planets Every 3 Secs \n 100000$",
                "60000 Planets Every 3 Secs \n  500000$",
                "100000 Planets Every 1 Secs \n 1000000$"};


    public HangarAdapter(Context context,String[] values) {
        super(context, R.layout.hangar_layout, values);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater theInflater = LayoutInflater.from(getContext());

        View theView = theInflater.inflate(R.layout.hangar_layout, parent, false);

        TextView TextView1 = (TextView) theView.findViewById(R.id.textView1);


        //TextView2 Is the text view i want the second string array to go into
        TextView TextView2 = (TextView) theView.findViewById(R.id.textView2);

        TextView1.setText(getItem(position));
        TextView2.setText(shipDesc[position])

        ImageView theImageView = (ImageView) theView.findViewById(R.id.imageView);

        return theView;
        }
