can'；在Android Google Map中无法获取addMarker上的代码段搜索列表

我在如何使用

onquerytexsubmit

和

onQueryTextChange

上遇到问题，我想要的是使用addMarker上的代码片段获得一个可搜索的车牌号。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，但是，

我总是得到最后一个值，而不是所有值。

请。帮助

我总是得到最后一个值，而不是所有值

您只会得到一个值（…可能），因为每次调用

createMarker（d，d2，plate_num）的方法都会创建一个全新的列表

public void createMarker（双纬度，最终双经度，字符串板编号）{
BitmapDescriptor image=BitmapDescriptorFactory.fromResource（R.drawable.bus）；
//list=new ArrayList（）；//停止这样做！

 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;
}

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!
