不兼容的类型:Fragment不能转换为Activity

Question

欢迎任何帮助
使用选项卡活动从android studio示例白色遗留android studio库
我的代码:

import android.net.Uri;
import android.os.Bundle;
import android.support.customtabs.CustomTabsIntent;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.epicmario71.globalfortress.R;
/**
* A simple {@link Fragment} subclass.
* Use the {@link Fragment1#newInstance} factory method to
* create an instance of this fragment.
*/
public class Fragment1 extends Fragment {
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;
public Fragment1() {
// Required empty public constructor
}
/**
* Use this factory method to create a new instance of
* this fragment using the provided parameters.
*
* @param param1 Parameter 1.
* @param param2 Parameter 2.
* @return A new instance of fragment Fragment1.
*/
// TODO: Rename and change types and number of parameters
public static Fragment1 newInstance(String param1, String param2) {
Fragment1 fragment = new Fragment1();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_1, container, false);
}
String url = "wwww.epicmario71.tk";
public void OpenRadio(View view) {
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(this, Uri.parse(url));
}
}

完整错误:错误:不兼容的类型:Fragment1不能转换为ActivitycustomTabsIntent。launchUrl(这,Uri.parse (url));^

任何帮助都是受欢迎的

问题在这一行:

customTabsIntent.launchUrl(this, Uri.parse(url));

相反，你必须传递活动上下文。你可以使用:-

customTabsIntent.launchUrl(getActivity(), Uri.parse(url));

或

customTabsIntent.launchUrl(getApplicationContext(), Uri.parse(url));

有希望地解决这个问题。
