onCheckedChanged called automatically
It's weird all of us have this problem but not official Google answer to this simple problem.
The MOST simple it's to check:
buttonView.isPressed()
If true, means the user clicked the view.
No global variables are needed.
I've ended up using this subclass of SwitchCompat to avoid this issue. This way I don't need boilerplate code where I'm using this class.
Whenever you need to change the checked without firing the listener, use setCheckedSilent
instead of setChecked
:
import android.content.Context;
import android.os.Parcelable;
import android.support.v7.widget.SwitchCompat;
import android.util.AttributeSet;
/**
* Created by emanuel on 30/5/16.
*/
public class Switch extends SwitchCompat {
private OnCheckedChangeListener listener;
public Switch(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
this.listener = listener;
super.setOnCheckedChangeListener(listener);
}
@Override
public void onRestoreInstanceState(Parcelable state) {
super.setOnCheckedChangeListener(null);
super.onRestoreInstanceState(state);
super.setOnCheckedChangeListener(listener);
}
public void setCheckedSilent(boolean checked) {
super.setOnCheckedChangeListener(null);
super.setChecked(checked);
super.setOnCheckedChangeListener(listener);
}
}
onRestoreInstanceState
was triggering the listening also, when set in the onViewCreated
method and you are going back to a previous fragment.
Hope it works for you!
Try this
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (buttonView.isPressed()) {
... //returns true, if user clicks the switch button
}}
