private class MagnificationObserver extends ContentObserver {MagnificationObserver(Handler mHandler){super(mHandler);}@Overridepublic void onChange(boolean selfChange, Uri uri) {try {int callState = Settings.Global.getInt(getActivity().getContentResolver(),Settings.Global.WFC_IMS_ENABLED, 0);mHandler.obtainMessage(callState).sendToTarget();//1 是打开 0 是关闭android.util.Log.e("myy","callState==== "+callState);Settings.System.putInt(getActivity().getContentResolver(),"vowifiIsChecked",callState);} catch (Exception e) {e.printStackTrace();}}}private Handler mHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {//实现自己想要实现的功能int isShow = Settings.System.getInt(getActivity().getContentResolver(),"isShow",1);boolean isVdfGr = getActivity().getResources().getBoolean(com.mediatek.internal.R.bool.sagereal_vowifi_dialog_gr);android.util.Log.e("myy","msg ===== "+msg + "isShow === "+isShow + "isVdfG === "+isVdfGr);if ((msg.what == 1) && (isShow ==1) && isVdfGr){showDialog();}}};
