Question

我在框架布局中使用片段，但由于某些问题，我想在Frame布局中启动一个Activity。我正在寻找这个已经有很长一段时间了，我得到的就是Tab规格所有这一切。我只想在我的Frame布局中启动活动，其中所有片段都打开

这是我如何打开我的片段和消息活动

private void displayView(int position) {
    switch (position) {
    case 0:
        fragment = new MyFeedsFragment();
        break;
    case 1:
        fragment = new MyPrivatePostsFragment();
        break;
    case 2:
        fragment = new MyProfileFragment();
        break;
    case 3:
        fragment = new PeopleFragment();

        break;
    case 4:

        Intent intent = new Intent(getApplicationContext(),
                MessagesActivity.class);
        startActivity(intent);

        break;
    case 5:
        fragment = new FavouritesFragment();
        break;
    case 6:
        fragment = new CreditsFragment();
        break;
    case 7:
        fragment = new SettingsFragment();
        break;
    case 8:
        fragment = new AboutThisAppFragment();
        break;
    case 9:
        fragment = new ContactUsFragment();
        break;
    case 10:
        fragment = new LogOutFragment();
        store.setLoginStatus(null);
        break;

    default:
        break;
    }

    if (fragment != null) {

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();
        if (!fragment.isAdded()) {
            fragmentTransaction.add(R.id.frame_container, fragment)
                    .addToBackStack(null).commit();
        } else {
            fragmentTransaction.show(fragment);
        }
        mDrawerList.setItemChecked(position, true);
        mDrawerList.setSelection(position);
        setTitle(navMenuTitles[position]);
        mDrawerLayout.closeDrawer(mDrawerList);

    } else {
        Log.e("Main Activity", "error in creating fragment");
    }

}

我希望Message Frag在我的片段中以相同的布局打开我怎么能这样做？

任何帮助将不胜感激..

在android中只有一个活动可以处于活动状态...如果您有片段活动并从其中一个片段运行另一个活动，则实际活动将暂停。您只能在实际的Activity中运行另一个Fragment或更改您的视图并调用您自己的refresh（）方法......

尝试以下代码：

LayoutInflater inflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.your_inflator_view, null);
Intent i = new Intent();
i.setClass(view.getContext(), MessageActivity.class);
view.getContext().startActivity(i);
