Checkbox selection

Question

Good night,

In my app, I need to select a total of 2 Checkbox boxes. After selecting 2 boxes, all others should be set with setEnabled(false).

So far so good, but how will I know which box was selected, WITHOUT KNOWING which box the user choose, and how will I simply give a setEnabled(false) in all others?

The logic would be like:

if(duasCheckBoxQualquer.isClick(){ todasAsOutrasCheckBox.setEnabled(false)

If anyone can help me, I’d appreciate it.

Gustavo, I don’t know if it would be the best, but one option would be to start an int variable and increment it or decrement it as it was marked or unchecked Checkboxes with a setOnCheckedChangeListener, and when incrementing the variable, run a method to uncheck the others...

checkBoxClicada.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
      if(isChecked) //ao marcar a checkbox
          {
              valorInteiro = valorInteiro + 1;
              if(valorInteiro == 2)
              {
                métodoParaDesabilitarOutrasCheckBoxesNãoMarcadas();
              }  
           }
       else //ao desmarcar checkbox
          {
              valorInteiro = valorInteiro - 1; 
              métodoParaHabilitarTodasAsCHeckBoxes();   
           }


    }

I do not know if I was clear... anything, comment on the answer... I hope to have helped :)
