问题描述
在我的应用中，我有一个RelativeLayout-> fragment(SupportMapFragment)| Relativelayout-> AutoCompleteTextView
In my app I have a RelativeLayout->fragment(SupportMapFragment)|Relativelayout->AutoCompleteTextView
搜索应执行Google Maps搜索栏应执行的操作，并从我的搜索关键字返回位置的下拉列表.完成输入并延迟几秒钟后，我的应用崩溃，并显示以下错误:
The search should do what Google Maps' search bar should do and return a dropdown list of locations from my search keyword. After I finish typing and a few second delay, my app crashes with the error:

我了解这可能是因为我无法在一个片段上扩大视图( https://stackoverflow.com/a/19815266/5336014 ).这是可以解决的吗?
I understand that this may be because I am not able to inflate a view over a fragment(https://stackoverflow.com/a/19815266/5336014). Is this something that is fixable?

}
};
return filter;
}
}
此外，我在解决此链接的另一个问题时遇到了此错误:为自动完成适配器过滤json结果
Also, I got this error solving another problem which can be found at this link: Filter json results for Autocomplete adapter
谢谢.
推荐答案
ArrayAdapter的两个参数构造函数，即ArrayAdapter (Context context, int resource)需要布局资源，而不是TextView的id.
The two argument constructor of ArrayAdapter i.e ArrayAdapter (Context context, int resource) expects layout resource and not id of a TextView.
您正在传递AutoCompleteTextView的ID，该ID会尝试膨胀，但由于没有具有该ID的布局而失败.将实例化适配器的行更改为:
You are passing id of your AutoCompleteTextView that it tries to inflate but fails as there is no layout with that id. Change the line where you instantiate your adapter to:
autoCompView.setAdapter(
new GooglePlacesAutocompleteAdapter(this,
android.R.layout.simple_list_item_1));
