Ich erhalte diesen Fehler. Ich habe viele Lösungen ausprobiert, aber ich konnte das nicht lösen. Hilf mir! Ich muss die Oberflächenansicht und die Schaltfläche mithilfe von Fragmenten zur Aktivität hinzufügen.
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;
}
}
