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：
