在preferenceChangeListener每一个设置 [英] OnPreferenceChangeListener for every setting

问题描述

我知道我可以做这样的事情：

I know that I can do something like this:

Preference pref = findPreference(getString(R.string.pref_vibrate_on_key));
pref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

        @Override
        public boolean onPreferenceChange(Preference preference,
                Object newValue) {
            LogUtil.d("Working!");
            return true;
        }

});

不过，我想一个监听器添加到每个preference。 我试着这样做的：

But I would like to add a Listener to every preference. I tried doing:

SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
sp.registerOnSharedPreferenceChangeListener(new OnSharedPreferenceChangeListener() {

        @Override
        public void onSharedPreferenceChanged(
                SharedPreferences sharedPreferences, String key) {
            LogUtil.d("working!");

        }

});

，但它不工作。 这可能吗？如果是的话，我究竟哪里做错了？

but it doesn't work. Is this possible? If so, what am I doing wrong?

推荐答案

我发现使用雷托•梅耶尔回答一个替代方法<一href="http://stackoverflow.com/questions/531427/how-do-i-display-the-current-value-of-an-android-$p$pference-in-the-$p$pference-sum">http://stackoverflow.com/questions/531427/how-do-i-display-the-current-value-of-an-android-$p$pference-in-the-$p$pference-sum

I found a workaround using Reto Meier answer at http://stackoverflow.com/questions/531427/how-do-i-display-the-current-value-of-an-android-preference-in-the-preference-sum

使用他的方法它的工作。

Using his approach it does work.
