I have 3 checkbox in my Layout:
- (case #1) mCheckBoxAll: when is checked or unchecked, all other boxes are set in the same state.
-
(case #2) mCheckBoxChoice1 and mCheckBoxChoice2: if one of these is unchecked by the user then the mCheckBoxAll must be unchecked.
mCheckBoxAll.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { mCheckBoxChoice1.setChecked(isChecked); mCheckBoxChoice2.setChecked(isChecked); } }); mCheckBoxChoice1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (!isChecked) mCheckBoxAll.setChecked(!isChecked); } }); mCheckBoxChoice2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (!isChecked) mCheckBoxAll.setChecked(!isChecked); } });
But this code doesn't work in case #2. All cases are unchecked in the same time...
