在Fragment中如何使用Toolbar

这个Toolbar实在折磨了我好几天。。。知道看到下面这个提醒然后出去吹了吹风，终于弄出来了....其实跟提醒无关。我卡在这句上了....

        toolbar.inflateMenu(R.menu.menu_main);

代码中还包含 fragment+viewpager+radiobutton实现的仿微信主界面效果。

还是要提醒：
在NoActionBar的主题中
1. onCreateOptionsMenu方法不会运行
2. 即使在关联ActionBar后也不会触发onCreateOptionsMenu，此监听只对ActionBar有效

FragmentStore.java

package com.example.demo.myapplication.fragment;

import com.example.demo.myapplication.R;
import com.example.demo.myapplication.activity.SelectActivity;
import com.example.demo.myapplication.activity.UpdatePhotoActivity;

public class FragmentStore extends Fragment {

    Activity mActivity;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mActivity = getActivity();

        //fragment的布局文件
        View view = inflater.inflate(R.layout.fragment_special_offer, container, false);
       
        TextView content = (TextView) view.findViewById(R.id.content);
        content.setText("商城");

        Toolbar toolbar = (Toolbar)view.findViewById(R.id.toolbar);

        ImageButton selectBtn= (ImageButton) view.findViewById(R.id.select);
        selectBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(mActivity,"你点击了选择按钮",Toast.LENGTH_SHORT).show();
            }
        });
 //导入fragment的menu文件 toolbar.inflateMenu(R.menu.menu_main); toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() { public boolean onMenuItemClick(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: mActivity.finish(); case R.id.overflow: Intent intent=new Intent(); intent.setClass(mActivity, SelectActivity.class); startActivity(intent); //设置切换动画，从右边进入，左边停留 mActivity.overridePendingTransition(R.anim.in_from_right, R.anim.stay); } return true; } }); return view; }}
