Android中Fragment中启动一个Activity，实例化控件。

相信大家对于在一个Activity中启动另一个Activity非常熟悉，具体代码如下。

searchView.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Intent mintent=new Intent(MainActivity.this,SearchActivity.class);                startActivity(mintent);                overridePendingTransition(R.animator.animator_in,R.animator.animator_out);            }        });

但是在一个Fragment中实现开启新的Activity中就不是这样了，

package com.example.app_weixin;import android.content.Intent;import android.media.MediaRecorder;import android.os.Bundle;import android.support.annotation.Nullable;import android.support.v4.app.Fragment;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.RelativeLayout;import android.widget.TextView;/** * Created by 尽途 on 2017/3/25. */public class Fragment_profile extends Fragment {    private RelativeLayout userinfo_re;    private TextView userName_tv,account_tv;    private ImageView userImage_iv;    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        View view=inflater.inflate(R.layout.fragment_profile,container,false);        initView(view);        initData();        return view;    }    void initView(View view){        userinfo_re=(RelativeLayout)view.findViewById(R.id.userinfo);//在Fragment中实例化控件        userImage_iv=(ImageView)view.findViewById(R.id.touxiangiv);        userName_tv=(TextView)view.findViewById(R.id.username);        account_tv=(TextView)view.findViewById(R.id.account_tv);    }    void initData(){        userImage_iv.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Intent mintent=new Intent(getActivity(),Activity_profile_account.class);//在Fragment中实现开启新的Activity                startActivity(mintent);            }        });    }}
