是否可以在没有触发按钮的情况下从片段中打开新活动？

这是我使用按钮从片段中打开新活动的代码。 

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.hello_world, container, false);

    Button newActivity = (Button) v.findViewById(R.id.click);
    newActivity.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            goToActivity();
        }
    });
    return v;
}

public void goToActivity(){
    Intent intent = new Intent(getActivity(), HomeActivity.class);
    startActivity(intent);
    getActivity().finish();
}

是否可以在没有触发按钮的情况下从片段中打开新活动？因为我在打开新活动时遇到了很多错误并且直接关闭片段活动：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.hello_world, container, false);

    goToActivity();
    return v;
}

public void goToActivity(){
    Intent intent = new Intent(getActivity(), HomeActivity.class);
    startActivity(intent);
    getActivity().finish();
}

首先，您无需以这种方式致电活动.finish()。 android Activity生命周期会自动为您处理 当您使用startActivity(intent)开始新活动时，之前的活动会自动调用其生命周期方法（最初为onPause()，然后为onStop()等）。

其次，活动显示片段。为什么在创建片段视图后，您是否希望片段启动不同的活动？我想您可能需要进一步了解Fragment和Activity生命周期。

附加：
当您启动新活动时，之前的活动会添加到Backstack中。您可以将backstack视为应用中活动的历史记录。每次按下后退按钮，都会返回应用程序的活动历史记录。您可以通过在AndroidManifest.xml文件中为该特定活动设置android:noHistory=true"来停止将活动添加到Backstack。

<activity
            android:name="xxx.xxxxxxx.xxxxxxx.MyActivity"
            android:label="@string/app_name"
            android:noHistory="true"  
            android:configChanges="orientation"
            android:screenOrientation="portrait"/>

尝试从onResume（）中调用goToActivity（）方法。
