[FIXED] Can not check radiobutton

Issue

why I can not check the same radiobutton after I uncheck it programmatically, when I click next button, unless I check another radiobutton.

This is the code that unchecks radiobuttons:

        if(q.trim() != null || q.trim() != ""){
            questionView.setText(q);
            r1.setChecked(false);
            r2.setChecked(false);
            r3.setChecked(false);

            r1.clearFocus();
            r2.clearFocus();
            r3.clearFocus();

            r1.setText(varNames.get("ra0"));
            r2.setText(varNames.get("ra1"));
            r3.setText(varNames.get("ra2"));
        }

And this is where I try to check it:

public void questionClicked(View view) {

    boolean checked = ((RadioButton) view).isChecked();

    switch(view.getId()) {
        case R.id.firstQuestion:
            if(!checked) {
                r1.setChecked(true);
            }
            getAnswer(R.id.firstQuestion);

            break;
        case R.id.secondQuestion:
            if(!checked) {
                r2.setChecked(true);
            }
            getAnswer(R.id.secondQuestion);

            break;
        case R.id.thirdQuestion:
            if(!checked) {
                r3.setChecked(true);
            }
            getAnswer(R.id.thirdQuestion);

            break;
    }
}

Solution

I think you should make a method of clearing checked radio button. And call it everytime you click "next" button. Here is an example:

private void clearcheck(){        
        if(q.trim() != null || q.trim() != ""){
            questionView.setText(q);
            r1.setChecked(false);
            r2.setChecked(false);
            r3.setChecked(false);

            r1.clearFocus();
            r2.clearFocus();
            r3.clearFocus();

            r1.setText(varNames.get("ra0"));
            r2.setText(varNames.get("ra1"));
            r3.setText(varNames.get("ra2"));
        }
}

Call it like clearcheck(); in onclick of your next button.
