用linearLayout替代ListView

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。

?下面这个压缩包项目只是相对应的框架形式，数据是死的
