问题描述

我有2个片段 mainFragment childFragment 。我想说明动作条中的 mainFragment ,但要在 childFragment 隐藏。所有工作正常,只是当我回来 mainFragment childFragment ,再次进入 childFragment 操作栏显示前几秒钟让隐藏..

我不知道为什么?帮助

childFragment 我这样做

  @覆盖
公共无效onResume(){
    super.onResume();
    ((ActionBarActivity)getActivity())getSupportActionBar()隐藏()。
    mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
    。getView()setFocusableInTouchMode(真正的);

        @覆盖
        公共布尔onKey(视图V,INT关键code,KeyEvent的事件){

            如果(event.getAction()== KeyEvent.ACTION_UP和放大器;&放大器;关键code == KeyEvent.KEY code_BACK){
                //处理后退按钮的点击监听器

                mainActivity.onBack pressed();
                。((ActionBarActivity)getActivity())getSupportActionBar()显示();
                mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
                返回true;
            }
            返回false;
        }
    });
}
 

解决方案

尝试做这在你的fragmen的onActivityCreated方式:

 ((ActionBarActivity)getActivity())getSupportActionBar()隐藏()。
mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
 

编辑:我假设你正在处理您的交易片段,在你的活动。在你替换你的片段活动:

  getSupportFragmentManager()的BeginTransaction()代替(R.id.frame_layout,新YourFragment())提交()。;
 

根据您要更换哪些片段做你的动作条隐藏和显示操作。 (主或子)

I have 2 Fragments mainFragment and childFragment. I want to show actionbar in mainFragment but wants to hide in childFragment. All is working fine except that when I comes back to mainFragment from childFragment and again goes to childFragment action bar shows for seconds before get hidden ..

I don't know why ?HELP

In childFragment I am doing this

@Override
public void onResume() {
    super.onResume();
    ((ActionBarActivity) getActivity()).getSupportActionBar().hide();
    mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
    getView().setFocusableInTouchMode(true);
    getView().requestFocus();
    getView().setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK) {
                // handle back button's click listener

                mainActivity.onBackPressed();
                ((ActionBarActivity) getActivity()).getSupportActionBar().show();
                mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
                return true;
            }
            return false;
        }
    });
}
解决方案

Try to do this in your fragmen's onActivityCreated method:

((ActionBarActivity) getActivity()).getSupportActionBar().hide();
mainActivity.mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

Edit:I assume that you are handling your fragment transactions in your activity. Before you replace your fragment in activity with:

getSupportFragmentManager().beginTransaction().replace(R.id.frame_layout, new YourFragment()).commit();

do your actionbar hide and show operations according to which fragment you are replacing. (main or child)
