有个关于android listview的问题 菜鸟一枚求助

Question

一个button 一个editext 一个listview 点击button后取得editext的值 然后把赋值到listview 每点击一次button创建一个listview的item然后item的数据就是editext取得的值

Answer 1

把edittext的值存在list里，每点击button，就list.add(edittext的值)，再写一个listview的适配器，传list，再刷新一遍适配器
private List list=new ArrayList<>();
private MyAdapter adapter;

1、button 点击事件：
String text=editText5.getText().toString();
if(!text.equals("")){
list.add(text);
adapter=new MyAdapter(this,list);
listview.setAdapter(adapter);
adapter.notifyDataSetChanged();

    }
2、适配器
 class MyAdapter extends BaseAdapter{
    private Context context;
    private List<String> list;

    public MyAdapter(Context context, List<String> list) {
        this.context = context;
        this.list = list;
    }

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder = null;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(
                    R.layout.dblist_item, parent, false);
            viewHolder = new ViewHolder(convertView);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        final String s = (String) getItem(position);
        viewHolder.textView.setText(s);

        return convertView;
    }
}
static class ViewHolder {
    @BindView(R.id.textView)
    TextView textView;

    ViewHolder(View view) {
        ButterKnife.bind(this, view);
    }
}
