Why after action associated with one checkbox both checkboxes are are disabled?

everyone! I want to implement app that:

1. Click on the checkbox
2. Move to new action
3. Complete new action
4. Return to checkbox action
5. Set clicked checkbox checked and disabled

In my code when I try to implement it the second checkbox is also checked and disabled despite the fact that I haven't clicked it.

Please help! See my code below:

     public void CheckboxCare(@NonNull View v){
    switch (v.getId()){
        case R.id.checkbox_p2106:
            if(pref.contains("checked") && pref.getBoolean("checked", false) == true){
                setChecked(P2106);
                disableCheckbox(P2106);
            }else{
                setNotChecked(P2106);
            }
            checkboxListener(P2106);
            break;
        case R.id.checkbox_mp2106:
            if(pref.contains("checked") && pref.getBoolean("checked", false) == true){
                setChecked(MP2106);
                disableCheckbox(MP2106);
            }else{
                setNotChecked(MP2106);
            }
            checkboxListener(MP2106);
            break;
    }
}

Create object for each check box send on that function call based on your requirement

public void CheckboxCare(@NonNull View v){
switch (v.getId()){
    case R.id.checkbox_p2106:
                     {
                     // write code here
                     }
    case R.id.checkbox_mp2106:
        if(pref.contains("checked") && pref.getBoolean("checked", false) == true){
            setChecked(checkbox_p2106);// enable one
            disableCheckbox(checkbox_p2106);// disable second
        }else{
            setNotChecked((CheckBox) v);
        }
        checkboxListener((CheckBox) v);
        break;
}
}
