主片段部分可见，具有当前片段android studio的混合视图

在我的android应用程序中有一个导航抽屉，它的默认加载片段是homefragment，因为主屏幕是homefragment。Home fragment上有imageview，它监听单击并在每个imageview上打开不同的片段，问题是片段在全屏上显示，而我希望它们显示在navigationview的工具栏下，当我按下后退按钮时，应用程序退出到主登录屏幕。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代码：

 public class HomeFragment extends Fragment {
ImageView im1,im2,im3,im4,im5,im6,im7,im8,im9,im10,im11,im12,im13,im14;

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

下面是homefragment:dashboard上一个ImageView的代码-->

这是另一个片段，单击其中一个图像视图时也被称为：

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，但是工具栏仍然缺失

在您的

MyLawyer

片段中替换此

fragmentTransaction.add(R.id.drawer_layout, fragment);

与

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使用了错误的id。replace（），因为它应该和我在导航抽屉中使用的一样，那就是R.id.frame

只需检查

活动

和

片段

生命周期。@Piyus我检查了，但我感到困惑，因为所有这些对我来说都是新的，特别是片段，当我单击homefragments按钮时，它会在前台显示该片段，而以前的homefragments则显示为背景或有时它只是不显示过路费添加您的代码too@VivekMishra请看我的最新问题now@VivekMishra它会给出错误，因为as不会解析我添加这段代码的方法，所以现在如果（container！=null）{container.removeAllViews（）；}但屏幕上仍然缺少toollbar，而当我从导航抽屉中访问相同的片段时，整个屏幕上都有工具栏

fragmentTransaction.add(R.id.drawer_layout, fragment);

fragmentTransaction.replace(R.id.drawer_layout, fragment);
