我的android应用程序中有一个导航抽屉，它的默认加载片段是home fragment，因为主屏幕是home fragment。家庭片段在其上点击图像，在每个图像视图上打开不同的片段，问题是在全屏上显示片段，而我希望它们在导航视图的工具栏下看到，当我按下按钮时，应用程序退出主登录屏幕。请有人建议我处理这个问题。
这是HomeFragment的代码，它是导航抽屉的默认值：
public class HomeFragment extends Fragment {
ImageView im1,im2,im3,im4,im5,im6,im7,im8,im9,im10,im11,im12,im13,im14;
@Override

if (container != null) {
container.removeAllViews();
}

container, false);

这里是homeFragment:Dashboard上其中一个ImageView的代码-->
public class DashboardFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
public static int int_items = 3 ;
private String tabTitles[] = new String[] { "Schedule", "Payments", "Judgements" };
private int[] imageResId = {
R.drawable.schedule_active,
R.drawable.payment_summary_active,
R.drawable.judgements_active
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
/**
*Inflate tab_layout and setup Views.
*/
View x = inflater.inflate(R.layout.tab_layout,null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
tabLayout.setSelectedTabIndicatorHeight(0);
/**
*Set an Apater for the View Pager
*/
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
/**
* Now , this is a workaround ,
* The setupWithViewPager dose't works without the runnable .
* Maybe a Support Library Bug .
*/
tabLayout.post(new Runnable() {
@Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
// createTabIcons();
return x;
}
class MyAdapter extends FragmentPagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
/**
* Return fragment with respect to Position .
*/
@Override
public Fragment getItem(int position)
{
switch (position){
case 0 : return new Schedule();
case 1 : return new Payment();
case 2 : return new Judgement();
}
return null;
}
@Override
public int getCount() {
return int_items;
}
/**
* This method returns the title of the tab according to the position.
*/
@Override
public CharSequence getPageTitle(int position) {
Drawable image = getView().getResources().getDrawable(imageResId[position]);
image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
// Replace blank spaces with image icon
SpannableString sb = new SpannableString(" " + tabTitles[position]);
ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
sb.setSpan(imageSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return sb;
}}}
下面是另一个片段，单击其中一个图像视图时也会调用它：
public class MyLawyerFragment extends Fragment {
ImageButton im1;
LinearLayout l1;
ChangeFragListener listener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
listener = (ChangeFragListener)getActivity();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (container != null) {
container.removeAllViews();
}
View v1 = inflater.inflate(R.layout.activity_mylawyer,
container, false);
im1 = (ImageButton) v1.findViewById(R.id.imageButton);
l1 = (LinearLayout) v1.findViewById(R.id.linearLayout4);
im1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
change("lawyer");
AddLawyer fragment = new AddLawyer();
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.drawer_layout, fragment);
// fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
l1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
LawyerDetailsFragment fragment = new LawyerDetailsFragment();
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.drawer_layout, fragment);
// fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
return v1;
}
private void change(String lawyer) {
}}
我添加了这段代码，现在两个屏幕没有合并，但是工具栏仍然丢失。
最佳答案
为了帮助其他可能遇到与我相同问题的人，我找到了解决问题的方法，因为我知道我对fragmenttransaction.replace（）使用了错误的id，因为它应该与我在导航抽屉中使用的id相同，即r.id.frame
