我想实现类似下图的功能。
自定义listView代码如下：
public class MyListView extends ListView {
public MyListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyListView(Context context) {
super(context);
}
public MyListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
//重写该方法后，导致listView无法滑动
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
}
}
适配器代码如下：
public class TestActAdapter extends BaseAdapter {
private Context mContext;
private List<RechargeBanlance> list;
MyListView myListView;
public TestActAdapter(Context mContext, List<RechargeBanlance> list,MyListView myListView) {
this.mContext = mContext;
this.list = list;
this.myListView=myListView;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
@Override
public Object getItem(int i) {
// TODO Auto-generated method stub
return list.get(i);
}
@Override
public long getItemId(int i) {
// TODO Auto-generated method stub
return i;
}
@Override
public View getView(int i, View view, ViewGroup viewgroup) {
ViewHolder vh = null;
if(view==null){
view = LayoutInflater.from(mContext).inflate(R.layout.item_recharge_detailed, null);
vh = buildViewHolder(view);
view.setTag(vh);
}else{
vh = (ViewHolder) view.getTag();
}
initData(viewgroup, vh, i);
return view;
}
public void initData(View view, Object viewHolder, int position) {
// if (!((RefreshListView) viewGroup).isMeasure()) {
ViewHolder vh = (ViewHolder) viewHolder;
RechargeBanlance bean = (RechargeBanlance) list.get(position);
Util.printLog("充值详细："+bean.getTime()+ ",position:"+position, 3);
if (bean.getType() == RechargeBanlance.DATA) {
vh.contentBox.setVisibility(View.VISIBLE);
vh.title.setVisibility(View.GONE);
vh.msg.setText(bean.getMsg());
vh.money.setText(""+bean.getMoney());
vh.date.setText(bean.getTime());
} else if (bean.getType() == RechargeBanlance.TITLE) {
vh.contentBox.setVisibility(View.GONE);
vh.title.setVisibility(View.VISIBLE);
vh.title.setText(bean.getTime());
}else{
Util.printLog("充值详细 类型不对", 3);
}
// setListViewHeightBasedOnChildren(myListView);
// }
}
public ViewHolder buildViewHolder(View view) {
ViewHolder vh = new ViewHolder();
vh.contentBox = (RelativeLayout) view.findViewById(R.id.contentBox);
vh.title = (TextView) view.findViewById(R.id.title);
vh.date = (TextView) view.findViewById(R.id.date);
vh.msg = (TextView) view.findViewById(R.id.msg);
vh.money = (TextView) view.findViewById(R.id.money);
return vh;
}
private class ViewHolder {
TextView title, msg, money, date;
RelativeLayout contentBox;
}
}
xml配置如下：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/box"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/WHITE"
android:orientation="vertical" >
<yftx.view.MyListView
android:id="@+id/myListView"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="@color/WHITE"
android:divider="@color/eee"
android:dividerHeight="1dip" >
</yftx.view.MyListView>
</RelativeLayout>
activity代码如下:
public class TestAct extends Activity implements OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.act_test);
mContext = this;
collectionList = (MyListView) findViewById(R.id.myListView);
list = new ArrayList<RechargeBanlance>();
for (int i = 0; i < 23; i++) {
RechargeBanlance bean = new RechargeBanlance();
if (i % 2 == 0) {
bean.setMsg("购买商品"+i);
bean.setMoney("+" + 10 + i);
} else if (i == 3) {
bean.setMsg("签到"+i);
bean.setMoney("+" + 10 + i);
} else {
bean.setMsg("兑换优惠卷"+i);
bean.setMoney("-" + 10 + i);
}
bean.setType(RechargeBanlance.DATA);
bean.setTime("03-1" + i);
list.add(bean);
}
adapter = new TestActAdapter(mContext, list,collectionList);
collectionList.setAdapter(adapter);
}
private MyListView collectionList;
private NumberPicker repetCount;
private TextView result, text;
private Button button1, button2, button3;
private Context mContext;
private List<RechargeBanlance> list;
private TestActAdapter adapter;
}
测试数据有30条，listView无法上下滑动，请问有没有朋友遇到过这个问题，这是怎么回事?
