我在如何使用onQueryTextSubmit和onQueryTextChange方面遇到问题我想要的是使用我的addMarker上的代码段来获取可搜索的版号。我现在的问题是我在onQueryTextSubmit下是一个区分大小写的错误值。我在列表中添加了我的标记，I am getting always the last value not all values.请。帮助

}
这里我要传递search title =“Plate No.”的值LatLng值的纬度和经度。
public boolean onQueryTextSubmit(String query) {
centerMarker(query);
for(Marker m : list) {
System.out.println(m.getSnippet() + m.getTitle() + m.getPosition() + " snippet");
if(m.getSnippet().equals(query)) {
Toast.makeText(this, "You searched for: " + query , Toast.LENGTH_SHORT).show();
mMapFragment.animateCamera(CameraUpdateFactory.newLatLngZoom(m.getPosition(), 9.0f));
break; // stop the loop
}
}
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
return false;
}
答案 0 :(得分：0)
我总是得到最后一个值而不是所有值。
您只能获得一个值（...可能），因为您在每次调用createMarker(d, d2, plate_num)
public void createMarker(Double latitude, final Double longitude, String Plate_num) {
BitmapDescriptor image = BitmapDescriptorFactory.fromResource(R.drawable.bus);
// list = new ArrayList<Marker>(); // Stop doing this!
