儿童片段无法充气菜单 [英] Child Fragment Not able to inflate Menu

问题描述

你好我试图夸大或更改子片段菜单，但没能如愿。
流程是这样的。

如果我尝试从活动的膨胀菜单（主）---做工精细。
 如果我尝试从infalte片段（SecondFrag）菜单----做工精细
 如果我尝试从膨胀（SecondFrag）的子片段菜单----不工作

样code是这样

  @覆盖
公共无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    setHasOptionsMenu（真）;
    Log.d（它具有不选项mener，+ hasOptionsMenu（））;
}
@覆盖
公共无效onCreateOptionsMenu（菜单菜单，MenuInflater气筒）{
    //super.onCreateOptionsMenu(menu，气筒）;
    Log.d（选项菜单，活动选项菜单）;
    。mActivity.getSupportMenuInflater（）膨胀（R.menu.deal_detaisl，菜单）;
    Log.d（选项菜单，活动选项菜单）;
}
@覆盖
公共布尔onOptionsItemSelected（菜单项项）{    开关（item.getItemId（））{
    案例R.id.deal_loc：
        mActivity.showMapFragment（）;
        打破;    案例R.id.deal_loc_route：
        mActivity.showMapRoute（）;
        打破;
    }
    返回false;
}
 

解决方案

  @覆盖
公共无效onCreateOptionsMenu（菜单菜单，MenuInflater气筒）{
    inflater.inflate（R.menu.deal_detaisl，菜单）;
    super.onCreateOptionsMenu（菜单，充气器）;
}
 

这应该为你工作，试试吧。

编辑：
您应该创建一个自定义的片段，使片段扩展的自定义片段。然后在你的活动为 onCreateOptionsMenu 就可以得到当前的片段并呼吁充气菜单的公共方法（叫它什么）。聊天讨论后，您的问题得到解决。

Hi i am trying to inflate or change menu from child fragment , but not able to do so. The flow is like this .

If I try to inflate menu from activity (Main)--- work fine. if i try to infalte menu from fragment (SecondFrag)----work fine if i try to inflate menu from child fragment of(SecondFrag)----do not work

Sample Code is like this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
    Log.d("It has option mener of not", ""+hasOptionsMenu());
}




@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    //super.onCreateOptionsMenu(menu, inflater);
    Log.d("Option Menu", "Activity Option Menu");
    mActivity.getSupportMenuInflater().inflate(R.menu.deal_detaisl, menu);
    Log.d("Option Menu", "Activity Option Menu");
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
    case R.id.deal_loc:
        mActivity.showMapFragment();
        break;

    case R.id.deal_loc_route:
        mActivity.showMapRoute();
        break;
    }
    return false;
}

解决方案

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.deal_detaisl, menu);
    super.onCreateOptionsMenu(menu, inflater);
}

This should work for you, try it.

Edit: You should create a custom Fragment and make the fragments extend that custom Fragment. Then in your Activity for onCreateOptionsMenu you can get the current Fragment and call a public method for inflating a menu (call it whatever). After a chat discussion, your problem was solved.
