例如，当我选择第一个项目时，也会选择第7个和第14个项目。但我只能让第一项的textview可见。可能是什么问题？
这是我的ItemClickListener：
theListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if (myList.get(position).getstopId().toString()
.equals(tempid)) {
Log.e("Clicked", tempid);
busstopid = tempid;
stopName = myList.get(position).getstopName()
.toString();
progress.setCancelable(false);
progress.setMessage(getString(R.string.pleasewait));
progress.setTitle(getString(R.string.loading));
progress.setIcon(R.drawable.ic_launcher);
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progress.setProgress(0);
progress.setMax(100);
progress.show();
new GetClosestBusList().execute();
tempid = "0";
}
else {
tempid = myList.get(position).getstopId()
.toString();
// Hide previously selected text view
if (selectedIndex > -1) {
int viewIndex = selectedIndex
- parent.getFirstVisiblePosition();
// if previously selected list item is still
// visible, hide its text view
if (viewIndex > -1
&& viewIndex < parent.getChildCount()) {
View itemView = parent
.getChildAt(viewIndex);
TextView textView = (TextView) itemView
.findViewById(R.id.stationRouteTimeTable);
TextView stationarrow = (TextView) itemView
.findViewById(R.id.routedetailarrow);
TextView iconbusonstop = (TextView) itemView
.findViewById(R.id.iconbusonstop);
LinearLayout stationlistitem = (LinearLayout) itemView
.findViewById(R.id.stationlistitem);
stationlistitem
.setBackgroundColor(color.white);
textView.setVisibility(View.GONE);
if (myList.get(position).getbusOnStop()
.toString().equalsIgnoreCase("1")) {
iconbusonstop
.setVisibility(View.VISIBLE);
} else
iconbusonstop.setVisibility(View.GONE);
stationarrow.setVisibility(View.GONE);
}
}
// Now you make the newly selected text view visible
// and
// remember the selected item
selectedIndex = position;
int viewIndex = selectedIndex
- parent.getFirstVisiblePosition();
View itemView = parent.getChildAt(viewIndex);
TextView itemView2 = (TextView) itemView
.findViewById(R.id.stationRouteTimeTable);
TextView stationarrow = (TextView) view
.findViewById(R.id.routedetailarrow);
TextView iconbusonstop = (TextView) view
.findViewById(R.id.iconbusonstop);
stationarrow.setTypeface(Typeface.createFromAsset(
getAssets(), "fontello.ttf"));
itemView2.setVisibility(View.VISIBLE);
stationarrow.setVisibility(View.VISIBLE);
if (myList.get(position).getbusOnStop().toString()
.equalsIgnoreCase("1"))
iconbusonstop.setVisibility(View.VISIBLE);
else
iconbusonstop.setVisibility(View.GONE);
itemView2.setBackgroundColor(color.white);
Double lat = Double
.parseDouble(((RouteDetailInfo) parent
.getItemAtPosition(position))
.getlat());
Double lng = Double
.parseDouble(((RouteDetailInfo) parent
.getItemAtPosition(position))
.getlng());
LatLng itemLocation = new LatLng(lat, lng);
googleMap.animateCamera(CameraUpdateFactory
.newLatLngZoom(itemLocation, 16));
}
}
});

Android会重复使用列表项（也称为flyweight模式），因此您需要在适配器的getView（）方法中检查模型的选定状态和未选中状态。
