Android - onTextChanged () called when the orientation of the phone changes
I tried to implement search using EditText
. whenever text is entered into a request EditText
, it is sent with the entered text in the method onTextChanged()
. When I change the orientation of the phone with the canceled results, the method onTextChanged()
is called again with the same text. How can I avoid redundant method call onTextChanged()
when orientation changes.
public void onTextChanged(CharSequence s, int start, int before, int count) {
final String enteredKeyword = s.toString();
if(isFragmentVisible && !enteredKeyword.equals("")) {
searchTimer.cancel();
searchTimer = new Timer();
TimerTask searchTask = new TimerTask() {
@Override
public void run() {
searchUser(enteredKeyword);
}
};
searchTimer.schedule(searchTask, 1500);
Log.i("", enteredKeyword);
}
}

I have this problem. So I moved addTextChangedListener to the post EditText method in onCreateView:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
EditText mSearchQuery = findViewById(R.id.search_query);
mSearchQuery.post(new Runnable() {
@Override
public void run() {
mSearchQuery.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//Some stuff
}
@Override
public void afterTextChanged(Editable s) {
}
});
}
});
}

You need to override the onConfigurationChanged method to get a callback when the orientation changes.
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
// landscape
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
// portrait
}
}
Add below line to manifest
android:configChanges= "orientation"
Now, based on the callback, you can do whatever you want.
