java - 在运行时在Adapter中添加TextView

Question

追加数组中的每条消息

m.getGenre()

作为数组中每条消息的 TextView 的新消息，我想为其创建 TextView 并附加

这是其中的 CustomListAdapter，我想在数组中循环并将数组中的每个项目附加为新的 TextView

public class CustomListAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<notofication> movieItems;
private final Context context;


public CustomListAdapter(Activity activity, List<notofication> movieItems,Context c) {
    this.activity = activity;
    this.movieItems = movieItems;
    this.context = c;
}

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

@Override
public Object getItem(int location) {
    return movieItems.get(location);
}

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

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

    if (inflater == null)
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if (convertView == null)
        convertView = inflater.inflate(R.layout.list_row, null);


    TextView title = (TextView) convertView.findViewById(R.id.title);
    TextView rating = (TextView) convertView.findViewById(R.id.rating);
    TextView genre = (TextView) convertView.findViewById(R.id.genre);
    TextView year = (TextView) convertView.findViewById(R.id.releaseYear);

    // getting movie data for the row
    final notofication m = movieItems.get(position);







    // title
    title.setText(m.getTitle());



    // rating
    rating.setText(String.valueOf(m.getRating()));


    String genreStr = "";
    for (String str : m.getGenre()) {
       //append every str as new textView
    }


    // release year
    year.setText(m.getYear());

    return convertView;
}

}

现在结果将是这样的(这只是示例)

我怎样才能为每条消息创建新的textView，就像这张图片

这是我的代码

    String genreStr = "";
    for (String str : m.getGenre()) {
       //append every str as new textView
    }

但我不知道如何创建新的 TextView 并将其附加到 CustomAdapter 中

Answer 1

使用这个例子

而不是这个......

TextView genre = (TextView) convertView.findViewById(R.id.genre);

用这个

LinearLayout mgenre = (LinearLayout) convertView.findViewById(R.id.genre);

注意:-在xml中将id类型的TextView更改为垂直方向的线性布局。

for(String genre:m.getGenre()){
    TextView text = new TextView(context);
    LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    text.setLayoutParams(p);
    text.setText(genre);
    text.setTextAppearance(R.style.boldText);

    mgenre.addView(text);
}

享受编码............
