我可以显示自动填充建议中的所有项目,但是当我单击某个项目时,我希望与该项目关联的经度和纬度坐标在地图上绘制。我目前不知道如何实现。 “请在这里帮忙。
我已粘贴我的方法
private void searchAutocomplete(){
DatabaseReference database = FirebaseDatabase.getInstance().getReference();
//Create a new ArrayAdapter with your context and the simple layout for the dropdown menu provided by Android
final ArrayAdapter<String> autoComplete = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1);
//Child the root before all the push() keys are found and add a ValueEventListener()
database.child("wr").child("clubs").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
//Basically, this says "For each DataSnapshot *Data* in dataSnapshot, do what's inside the method.
for (DataSnapshot suggestionSnapshot : dataSnapshot.getChildren()){
//Get the suggestion by childing the key of the string you want to get.
String suggestion = suggestionSnapshot.child("name1").getValue(String.class);
//Add the retrieved string to the list
autoComplete.add(suggestion);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
AutoCompleteTextView ACTV= (AutoCompleteTextView)findViewById(R.id.autocompleteView);
ACTV.setAdapter(autoComplete);
ACTV.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
}

您应该将final ArrayAdapter<String> autoComplete
更新为类似final ArrayAdapter<Place> autoComplete
的内容,然后执行以下操作:
公共课地点{
private float latitude;
private float longitude;
private String name;
// implement your constructor
// implement your accessors
}
然后从您的onClick
收到Place
,您就可以执行place.getLatitude()
和place.getLongitude
之类的操作。
我就是这样实现的。

您只需要监听点击事件,并在点击某个项目时添加Marker
。
示例:
tv.setOnItemClickListener((adapterView, view, pos, id) -> {
mGoogleMap.addMarker(new MarkerOptions()
.position(mDataList.get(pos).getLocation()));
});
您需要确保您的Google地图已经加载了。
