我应该怎么做才能让Android电话 onShared preferenceChanged

What should I do to make android call onSharedPreferenceChanged?

推荐答案

最有可能的，它是由GC垃圾回收。我以前也遇到了这个问题。做一个全局变量，这使硬参考监听器。

Most likely, it is being garbage collected by gc. I have faced this problem before. Make a global variable which keeps a hard reference to the listener.

  OnSharedPreferenceChangeListener listener = new SharedPreferences.OnSharedPreferenceChangeListener() {
      public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
        // Implementation
      }
    };
