Google Android example source code - is text changed in EditText ?
EditText hEditText;
// TextChanged in onCreate
hEditText = (EditText)findViewById(R.id.idEditText);
hEditText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable str) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence sq, int start, int before,
int count) {
}
});Try some solution - each individually or all
- Check AndroidManifest.xml activity declaration
<activity android:name=".EnableProfileActivity" android:label="@string/app_name" /> - Delete BUILD folder in module tree and Clean / Rebuild project
- Restart Android Studio
public class Panel extends SurfaceView implements SurfaceHolder.Callback {
//............... code
//............... some code
/**
* Process the MotionEvent.
*/
@Override
public boolean onTouchEvent(MotionEvent event) {
synchronized (getHolder()) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
performClick();
} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
if(_currentGraphic==null)return true;
} else if (event.getAction() == MotionEvent.ACTION_UP) {
}
return true;
}
}
/////////////////////////////
@Override
public boolean performClick() {
// Calls the super implementation, which generates an AccessibilityEvent
// and calls the onClick() listener on the view, if any
super.performClick();
// Handle the action for the custom click here
return true;
}
}
You have to add constructor!
public static class YourFragment extends Fragment {
//you have to add constructor!!!!!
public YourFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
return view;
}
}
int[] mArrayOfInt;
String[] mArrayOfString;
List<String> mList;
public void saveState(Bundle map)
{
map.putIntArray("mArrayOfInt", mArrayOfInt);
map.putStringArray("mArrayOfString", mArrayOfString);
map.putStringArrayList("mList", mList);
}
public void restoreState(Bundle map)
{
mArrayOfInt= map.getIntArray("mArrayOfInt");
mArrayOfString = map.getStringArray("mArrayOfString");
mList = map.getStringArrayList("mList");
}
