Google API 已连接，但在 android 中提出了未针对 AutoCompleteTextView 提出的建议
Google API connected but place sugesstions not giving for AutoCompleteTextView in android
大家好，
我们面临一个关于 google 地图的问题，即使用 AutoCompleteTextview 查找地点。
我们收到 Google API 已连接的消息，但 AutoCompleteTextView 没有显示地点，即没有给出任何地点建议

提前致谢
试试这个
((TextView) findViewById(R.id.startpoint)).setOnClickListener(this);
在 OnClick(View)
里面
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN).build(Final_maps.this);
startActivityForResult(intent, REQUEST_INT);
Select地点：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Place place = PlaceAutocomplete.getPlace(Final_maps.this, data);
Log.d(TAG, place.toString());
((TextView) findViewById(R.id.startpoint)).setText(place.getName());
