Android CheckBox callback fromUser

Question

Is there a way to check if CheckBox is checked from user

private android.widget.CheckBox.OnCheckedChangeListener checkboxListener = new android.widget.CheckBox.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    }

---

UPDATE

I solved this by implementing custom CheckBox class which wraps CheckBox and holds boolean value fromUser, also implemented custom listener, and overloading setChecked(boolean checked, boolean fromUser).

`public class PaCheckBox extends CheckBox {

private static boolean fromUser;

public PaCheckBox(Context context) {
    super(context);
}

public PaCheckBox(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public PaCheckBox(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public void setChecked(boolean checked, boolean fromUser){
    setChecked(checked);
    PaCheckBox.fromUser = fromUser;
}

@Override
public void setChecked(boolean checked) {
    super.setChecked(checked);
    PaCheckBox.fromUser = true;
}

@Override
public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
    super.setOnCheckedChangeListener(listener);
}

public static class PaOnCheckBoxChangeListener implements android.widget.CheckBox.OnCheckedChangeListener {



    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked, boolean fromUser) {

    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        onCheckedChanged(buttonView,isChecked,PaCheckBox.fromUser);
    }
}

} `

 {
      if(isChecked)

Answer 2

you are going with right code you need to put just condition.

    private android.widget.CheckBox.OnCheckedChangeListener checkboxListener = new      android.widget.CheckBox.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked)
        Log.e("Log","user checked box");
    else
        Log.e("Log","user Unchecked box");
    }

Answer 3

it is an interesting question which has generated some confusion. I believe what you are asking for is similar to the SeekBar fromUser boolean whch denotes whether the user has clicked the screen or whether the checkbox has been altered programatically. A useful example of this requirement is when propogating a listview with checkboxes. As the View is current, the values are required to be set either by a holder of by entering the relevant data. An OnClickListener will be triggered regardless as to whether the user has touched the srceen as a deliberate selection. Whereas in the case of the SeekBar the boolean fromUser allows the programmer to make a choice.... as you have done with your wrapper. I am new to java and though, I am sure there must be a solution apart from your wrapper, I havent found one yet... will let you know if I do.

Just an idea, that I find has worked, use OnClickListener. It is only called when a user touches the control. It is not called if app changes check state.

    findViewById(R.id.switchFound).setOnClickListener(new View.OnClickListener () {
        @Override
        public void onClick(View v) {

            boolean isChecked = ((Switch) v).isChecked();

        }
    });

Answer 5

boolean isChecked in onCheckedChanged() represents exactly that. If its true then CheckBox is checked and if false then unchecked.

private android.widget.CheckBox.OnCheckedChangeListener checkboxListener = new android.widget.CheckBox.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked)
            // user has check the checkbox
        else
           // user has uncheck it
}

From official document

 public abstract void onCheckedChanged (CompoundButton buttonView, boolean isChecked)

Called when the checked state of a compound button has changed.

Parameters

buttonView - The compound button view whose state has changed.

isChecked - The new checked state of buttonView.

Note: I would highly encourage you to read the documentation to understand anything you have doubts about before asking for help.

Try like this ,

 checkBox.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (checkBox.isChecked()) {
                    //your code here  
                    //this will be true here by default you need not write checkBox.setChecked(true);
                } else {
                    //not checked by user
                    //this will be false here by default you need not write checkBox.setChecked(false);
                }
            }
        });
