我对 android studio 相当陌生，所以我会尽力解释。我使用碎片制作了一个菜单，所以我的activity_home活动是碎片化的。在碎片活动中，我创建了一个按钮，单击该按钮后，应该打开一个新活动。问题是我不知道如何实现onClickListener碎片活动内部。我所经历的每一个教程都是从头开始的。这是我的主要活动：package com.example.relja.diplomskirad;import android.os.Bundle;import android.support.design.widget.TabLayout;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentPagerAdapter;import android.support.v4.view.ViewPager;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.View;import android.widget.Button;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity { private Toolbar toolbar; private TabLayout tabLayout; private ViewPager viewPager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(false); viewPager = (ViewPager) findViewById(R.id.viewpager); setupViewPager(viewPager); tabLayout = (TabLayout) findViewById(R.id.tabs); tabLayout.setupWithViewPager(viewPager); } private void setupViewPager(ViewPager viewPager) { ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); adapter.addFragment(new home(), "Home"); adapter.addFragment(new profil(), "Profil"); adapter.addFragment(new mapa(), "Mapa"); viewPager.setAdapter(adapter); } class ViewPagerAdapter extends FragmentPagerAdapter { private final List<Fragment> mFragmentList = new ArrayList<>(); private final List<String> mFragmentTitleList = new ArrayList<>(); public ViewPagerAdapter(FragmentManager manager) { super(manager); }

你可以试试这个..这会有所帮助
public class home extends Fragment {
private Button btn_dumge_login;
public home() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_home, container, false);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
btn_dumge_login = view.findViewById(R.id.dumgeLogin)
btn_dumge_login.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), TestActivity.class) ;
getActivity().startActivity(intent);
}
});
}
}

View view = inflater.inflate(R.layout.your_layout_file, container, false);
view.findViewById(R.id.button_id).setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
getContext().startActivity(new Intent(getContext(), YourNewActivity.class));
});
return view;
您可以在 onCreateView() 方法的片段“home”中使用此代码

您应该首先选择要从中导航的视图，例如 ID 为 dugmeLogin 的按钮
那么你的代码应该是这样的
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_home, container, false);
Button loginButton = view.findViewById(R.id.dugmeLogin);
loginButton.setOnClickListener(v -> {
// You code goes here
});
return view;
}
这是你的 home.java
