Logcat Throws errors when overlaying a Fragment with a SurfaceHolder

Question

I am trying to overlay afragment with cameraPreview instance. The root of the fragment layout has a xml tag <surfaceview. When I run the App it crashes and throws the below errors. any idea why that happens?

Class_Extends_Fragment:

    public class CameraPreviewFragment extends Fragment {

private CustomCameraView mCameraPreview = null;

@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    mCameraPreview = new CustomCameraView(this.getActivity());
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    View view = inflater.inflate(R.layout.camerapreviewfragment, null);
    return view;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);

    SurfaceView sv = (SurfaceView) getView().findViewById(R.id.surfaceView);

}

MainActivity_layout:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.fragmentwithcamerasurface.MainActivity"
tools:ignore="MergeRootFrame">
    <fragment
        android:name="com.example.fragmentwithcamerasurface.CameraPreviewFragment"
        android:id="@+id/fragment00ID"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
    </fragment>

fragmentRoot_layout:

<FrameLayout 
xmlns:android="http://schemas.android.com/apk/res/android"    
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:ignore="MergeRootFrame"
android:background="#ffff00">

<!--logcat complains about this line-->
    <com.example.fragmentwithcamerasurface.CustomCameraView
    android:id="@+id/surfaceView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"/>

You're using the wrong layout file as your fragment's root layout. The layout file you inflate in getView() should be the file specifying the views you want to see inside the fragment, not the fragment itself.

I believe the layout inflater only goes 25 steps deep recursively.

You should add false as a third argument to LayoutInflater.inflate.

And CameraPreviewFragment is not a Context.

ok, if `CameraPreviewFragment` has no context, and to instantiate an object from a class that extends surfaceholder you should provide a context, how can this be solved? – Amrmsmb May 28 '14 at 07:00
@Amr no no, look at my first sentence. – dcow May 28 '14 at 07:06
ok, i modified it to be "View view = inflater.inflate(R.layout.camerapreviewfragment, null, false);" but unfoortunately the same error – Amrmsmb May 28 '14 at 07:08
Post your fragment's layout file then. – dcow May 28 '14 at 07:11
please see both of fragment_root and mainActivtiy_layout are posted above – Amrmsmb May 28 '14 at 07:23

First of all inflating with R.layout.camerapreviewfragment but the layout you are creating is fragmentRoot_layout and

tools:context="com.example.fragmentwithcamerasurface.CameraPreviewFragment"

CameraPreviewFragment is not a context

Hey checkout this for details about tools:context

when i added the line "tools:context.." i thought it is important. but knw ideleted it as you suggested but i receive the same error! would you please tell me when this line "tools:context.." is useful? – Amrmsmb May 28 '14 at 07:07
The `tools:context` line is not the culprit. @Troopers you literally copy-pasted my answer. – dcow May 28 '14 at 07:10
@dcow FYI the moment I opened the question in an another tab that time there was no answer for this so I answered the question without checking out your answer.....and also now you have edited about the layout file so :D ..... – Toppers May 28 '14 at 07:24
Had that before you too (; – dcow May 28 '14 at 07:27
