Android:Intent要求删除参数&；getBaseContext（）请求创建其方法

我正在尝试制作3个标签，其中包含来自的片段，并在第3个标签中查找与我的意图相关的问题。我试过这个方法，但没什么变化。这还是个错误

    package com.spamcity;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.widget.ImageButton;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;

public class postingActivity extends Fragment {

    private ImageButton infrastructure;
    private ImageButton trafficjam;
    private ImageButton others;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            View V = inflater.inflate(R.layout.posting_activity, container, false);

        setupVariables();
        addListenerOnButton();
        return V; 
    }

    public void addListenerOnButton() {
        Intent intent = new Intent(getBaseContext(), writeActivity.class); // error
        // want me to create method getBaseContext()

    // infrastructure
        infrastructure.setOnClickListener(new OnClickListener() { 
            @Override
            public void onClick(View arg0) {
                startActivity(intent); //error
                finish(); 
            } 
        });

    // traffic jam
        trafficjam.setOnClickListener(new OnClickListener() {            
            @Override
            public void onClick(View arg0) {
                startActivity(new Intent(postingActivity.this, writeActivity.class)); // error
                finish();
            } 
        });

    // others
        others.setOnClickListener(new OnClickListener() {            
            @Override
            public void onCzlick(View arg0) {
                startActivity(new Intent(postingActivity.this, writeActivity.class)); // error
                finish();
            }

        });

    }

    protected void finish() {
        // TODO Auto-generated method stub
        // they require this method to be exist
        // but I dont know what should I write here
    }

    private void setupVariables(){
        infrastructure = (ImageButton) findViewById(R.id.btnInfra);
        trafficjam = (ImageButton) findViewById(R.id.btnTrafJam);
        others = (ImageButton) findViewById(R.id.btnOther);
    }
}

我不明白这里出了什么问题。谢谢你的帮助。

试试看 getActivity（） 而不是 getBaseContext（）

这工作正常

试试这个

谢谢！星际触觉的错误现在都消失了。我想知道你知道为什么他们要求为finish（）和findViewById（int）创建it方法吗？它说该方法未定义。然后使用get activity.finish（）和v.findViewById（）activity.finish（）不起作用，我尝试了这个--View v=getLayoutInflater（）.inflate（R.layout.posting_activity，null）；--但是该行出错。很抱歉，是getActivity.finish（）；和v=充气机充气（R.layout.posting_活动，容器，假）；使用此选项我尝试过，但getActivity（）也不起作用。对于v，它是--View v=充气机。充气（R.layout.posting_aduan，container，false）；--，正当此行获取“充气器”和“容器”部分的错误，但ImageButton部分与v一起工作。请立即尝试。我做了一些改变
