android - 无法达到按钮错误的声明

Question

我点击一个按钮打开一个目标 URL，但是我无法到达 XML Layout BookmarkFragment.java 的语句，错误主要在 setonclicklistener

import android.os.Bundle;

import androidx.fragment.app.Fragment;

import android.text.method.LinkMovementMethod;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

import com.example.recipeappandroid.R;

public class BookmarkFragment extends Fragment {
    Button Click;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_bookmark, container, false);
        return inflater.inflate(R.layout.fragment_bookmark, container, false);
        Click = (Button) view.findViewById(R.id.prem);
        Click.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String url = "";
                Intent i = new Intent(Intent.ACTION_VIEW);
                i.setData(Uri.parse(url));
                startActivity(i);
            }
        });

    return view;
    }
}

这是 XML 布局的代码

片段书签.xml

<?xml version="1.0" encoding="utf-8"?>

    xmlns:tools="http://schemas.android.com/tools"

这是你的问题

return inflater.inflate(R.layout.fragment_bookmark, container, false);

您正在返回视图，因此该方法已终止。
因此，删除此行。最后上课：

public class BookmarkFragment extends Fragment {
    Button Click;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_bookmark, container, false);
        Click = (Button) view.findViewById(R.id.prem);
        Click.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String url = "";
                Intent i = new Intent(Intent.ACTION_VIEW);
                i.setData(Uri.parse(url));
                startActivity(i);
            }
    });

return view;
}

}
