Checking toggle button state in android?

Question

How to maintain the state of toggle buttons, like if we press button1 then it remembers the on state of button1 and won't allow us to press button2, and vice versa. Please help me out in solving this problem.

Answer 1

Try this.

Declare variables

ToggleButton mToggleOne;
ToggleButton mToggleTwo;

In onCreate

mToggleOne = (ToggleButton) findViewById(R.id.toggle_button1);
mToggleTwo = (ToggleButton) findViewById(R.id.toggle_button2);

SharedPreferences spref = getSharedPreferences();
if(spref.getBoolean("one", false)) {
    mToggleOne.setChecked(true);
    mToggleTwo.setEnabled(false);    
} else if(spref.getBoolean("two", false)) {
    mToggleTwo.setChecked(true);
    mToggleOne.setEnabled(false);    
}
mToggleOne.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
       mToggleTwo.setEnabled(!isChecked);
       getSharedPreferences().edit()
           .putBoolean("one", isChecked)
           .apply();
       //other code
    }
});

mToggleTwo.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
       mToggleOne.setEnabled(!isChecked);
       getSharedPreferences().edit()
           .putBoolean("two", isChecked)
           .apply();
       //other code
    }
});
