मुझे यह त्रुटि मिल रही है। मैंने कई समाधानों की कोशिश की लेकिन मैंने इसे हल नहीं किया। मेरी मदद करो! मुझे अंशों का उपयोग करके गतिविधि को सतह दृश्य और बटन जोड़ना होगा।
CamActivity.java:
public class CamActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cam);
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmentContainer);
if(fragment == null) {
fragment = new CamFragment();
fm.beginTransaction()
.add(R.id.fragmentContainer, fragment)
.commit();
}
}
}
CamFragment.java:
public class CamFragment extends Fragment {
private static final String TAG = "CamFragment";
private Camera mCamera;
private SurfaceView mSurfaceView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.camera_fragment, parent);
Button capturePic = (Button)v.findViewById(R.id.img_capture);
capturePic.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getActivity().finish();
}
});
mSurfaceView = (SurfaceView)v.findViewById(R.id.surfaceView1);
return v;
}
}
