博主 我想把文字换成图片 要怎么修改呢??
用linearLayout代替ListView
因为一个界面上面的内容太多,下面ListView查看不到,想在外面
加上scrollView,可是还是不行,结果没办法,用linearlayout代替
。对于具体要求,自己慢慢完善,这个相当于一个框架形式:
自己修改的地方:
public class AdapterForLinearLayout extends BaseAdapter { private LayoutInflater mInflater; private List<Map<String, Object>> data; public int count; private Context context; public AdapterForLinearLayout(Context context) { super(); this.context = context; this.mInflater = (LayoutInflater) context .getSystemService("layout_inflater"); this.data = new ArrayList<Map<String, Object>>(); count = data.size(); } public final class ListItemView {// 自定义控件集合 public TextView thread_number; public TextView thread_author; public TextView thread_time; public TextView thread_text; } public int getCount() { return data.size(); } public Object getItem(int position) { return data.get(position); } public long getItemId(int position) { return position; } public void addList(List<Map<String, Object>> mList) { data.addAll(mList); } public void remove(List<Map<String, Object>> mList) { data.remove(mList); } public View getView(int position, View convertView, ViewGroup arg2) { ListItemView listItemView = null; if (convertView == null) { listItemView = new ListItemView(); convertView = LayoutInflater.from(context).inflate( R.layout.forum_threaddetails_item, null); listItemView.thread_number = (TextView) convertView .findViewById(R.id.thread_number); listItemView.thread_author = (TextView) convertView .findViewById(R.id.thread_author); listItemView.thread_time = (TextView) convertView .findViewById(R.id.thread_time); listItemView.thread_text = (TextView) convertView .findViewById(R.id.thread_text); convertView.setTag(listItemView); } else { listItemView = (ListItemView) convertView.getTag(); } listItemView.thread_number.setText((String) data.get(position).get( "thread_number")); listItemView.thread_author.setText((String) data.get(position).get( "thread_author")); listItemView.thread_time.setText((String) data.get(position).get( "thread_time")); listItemView.thread_text.setText((String) data.get(position).get( "thread_text")); return convertView; } /** * 绑定视图 * * @param view * @param item * @param from */ private void bindView(View view, Map<String, Object> item, String from) { Object data = item.get(from); if (view instanceof TextView) { ((TextView) view).setText(data == null ? "" : data.toString()); } } }
/** * 绑定布局 */ public void bindLinearLayout() { int count = adapter.getCount(); for (int i = 0; i < count; i++) { View v = adapter.getView(i, null, null); v.setOnClickListener(this.onClickListener); if (i == count - 1) { LinearLayout ly = (LinearLayout) v; ly.removeViewAt(2); } addView(v, common.mNUM); common.mNUM++; } }
private ArrayList<Map<String, Object>> initValues() { list_buffer = CommonUtil.parseXml2(buffer, "r"); adapter = new AdapterForLinearLayout(this); ArrayList<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); int total = common.CURRENTPAGE * common.PAGESIZE; if (list_buffer.size() <= 0) { // return; Toast.makeText(ThreadDetailsActivity.this, "没有回复内容", Toast.LENGTH_SHORT).show(); } else { if (total < list_buffer.size()) { addPageMore(); } for (int i = (common.CURRENTPAGE - 1) * common.PAGESIZE; i < total; i++) { if (total >= list_buffer.size()) { total = list_buffer.size(); } String mContent = (String) list_buffer.elementAt(i); detailAuthor = CommonUtil.parseXml(mContent, "a"); Content = CommonUtil.parseXml(mContent, "c"); floor = CommonUtil.parseXml(mContent, "l"); Time = CommonUtil.parseXml(mContent, "rt"); Map<String, Object> win = new HashMap<String, Object>(); win.put("thread_number", floor + "楼"); win.put("thread_author", detailAuthor); win.put("thread_time", Time); win.put("thread_text", Content); list.add(win); } } return list; } 然后调入到Handler handler = new Handler() { public void handleMessage(Message msg) { //具体.... }中。
我自己做的一个是论坛帖子详情,以及回帖,跟帖,而且是带分页效果的:
