Solution: Try Clean your project Project » Clean » Clean projects selected below » select your project and click OK.
Try to delete the invalid code and type it again:
LinearLayout layout = (LinearLayout) findViewById(R.id.layout); // delete R.id.layout
LinearLayout layout = (LinearLayout) findViewById();
LinearLayout layout = (LinearLayout) findViewById(R.id.layout); // re-write this code R.id.layout
public class Main extends Activity {
private TextView mTextView;
private Activity mAct;
private Intent mIntent;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
mTextView = findViewById(R.id.mTextView);
mAct = getActivity();
mIntent = getIntent();
}
}
to:
public class Main extends Fragment{
private TextView mTextView;
private FragmentActivity mFrgAct;
private Intent mIntent;
private LinearLayout mLinearLayout;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_main, null);
return root;
}
public void onViewCreated(View view, Bundle savedInstanceState) {
// you can add listener of elements here
/*Button mButton = (Button) view.findViewById(R.id.button);
mButton.setOnClickListener(this); */
mTextView = view.findViewById(R.id.mTextView);
mLinearLayout = (LinearLayout)view;
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mFrgAct = getActivity();
mIntent = mFrgAct.getIntent(); // Intent intent = new Intent(getActivity().getIntent());
}
}
Screen Android example source code for developers.
Get orientation of screen.
Get orientation of screen.
public int getScreenOrientation() {
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
return 1; // Portrait Mode
}else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
return 2; // Landscape mode
}
return 0;
}
If you using Context as parameter of function try this solution:
public class MyActivity extends Activity {
// bla bla bla .......
//error
myFc( getapplicationcontext());
// OK
myFc(MyActivity.this);
