但我的结果变成了
我该如何解决?
更新1
我的 listAdapter.java
UPDATE1
my listAdapter.java
public class ListAdapter1 extends BaseAdapter {
private LayoutInflater myInflater;
private List<SmsInformation> list;
public ListAdapter1(Context context) {
myInflater = LayoutInflater.from(context);
}
public void setData(List<SmsInformation> list2) {
this.list = list2;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
if (list.get(position).getTypeOfSms().equals("send"))
convertView = myInflater.inflate(R.layout.raw_left, null);
else
convertView = myInflater.inflate(R.layout.raw_right, null);
holder = new ViewHolder();
holder.message = (TextView) convertView.findViewById(R.id.message);
holder.dateAndTime = (TextView) convertView.findViewById(R.id.dataAndTime);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.message.setText(list.get(position).getMessageContent());
holder.dateAndTime.setText(list.get(position).geTime()+list.get(position).getDate());
return convertView;
}
static class ViewHolder {
TextView message;
TextView dateAndTime;
}
}
推荐答案
所做的更改:
~ 在 row_right.xml &row_left.xml，父LinearLayout的layout_width属性应该设置为wrap_content而不是match_parent
~ in row_right.xml & row_left.xml, layout_width attribute of the parent LinearLayout should be set to wrap_content instead of match_parent
~在main.xml中，ListView的layout_width属性应该设置为match_parent.不是 wrap_content
~ in main.xml, layout_width attribute of ListView should be set to match_parent. not wrap_content
试试下面的代码:
