監聽WFC_IMS_ENABLED的開關

1.註冊

private MagnificationObserver magnificationObserver;


magnificationObserver = new MagnificationObserver(mHandler);        getActivity().getContentResolver().registerContentObserver(Settings.Global.getUriFor(Settings.Global.WFC_IMS_ENABLED), false,magnificationObserver,
                UserHandle.USER_ALL);

2.監聽

private class MagnificationObserver extends ContentObserver {
        MagnificationObserver(Handler mHandler){
            super(mHandler);
        }
        @Override
        public 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 是打開 0 是關閉
                    android.util.Log.e("myy","callState==== "+callState);
                    Settings.System.putInt(getActivity().getContentResolver(),"vowifiIsChecked",callState);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
    private Handler mHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
        //實現自己想要實現的功能
        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();
            }
        }
    };
