tiCourse

Course
CourseManager.getInstance().getCurrCourseId();
tiCourse
CetTypeLogic.getCetType()
courseSetPrefix  对应 yy46j  通过 Const.CET 来索取
tiCourse  对应 yy4j 或者 yy6j

连接四六级数据库命令

mysql -h10.51.101.246 -p3306 -uenglish -p'English!@#'  ape_english
show databases;
use ape_english;

怎么屏蔽掉一个 router

com.fenbi.android.yingyu.router.MemberRightsPage
@Route(value = {"/member/rights", "/{coursePrefix}/member/center", "/{coursePrefix2}/member", "/member/center"}, priority = 1)
public class MemberRightsPage implements IRouting {
    //  com.fenbi.android.module.vip.rights.MemberRightsActivity
    @Override
    public boolean routing(Context context, Page page, Callback callback) {
        //  Cet has no vip logic
        return true;
    }
}

取 Exception

Throwable

debugParams.put("exception", ExceptionUtils.dump(e));

多文件上传

com.fenbi.android.cet.camera.CameraApi#doUpload

intent 取数据

打印所有参数
URLDecoder.decode(getIntent().toUri(0))
LogUtils.e(URLDecoder.decode(getIntent().toUri(0)));
获取 router 
getIntent().getStringExtra(Const.KEY_ROUTER_PATH);
@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    if (intent != null) {
        tiCourse = intent.getStringExtra("tiCourse");
//  必须先转成字符串
        tagId = Integer.parseInt(intent.getStringExtra("tagId"));
        tagName = intent.getStringExtra("tagName");
    }
    renderEntranceParams();
    recyclerView.scrollTo(0, 0);
    cetRefreshView.autoRefresh();
}

页面参数

页面参数
com.fenbi.android.business.cet.common.utils.CetPageUtil

复制到剪切板

com.fenbi.android.module.yingyu.mkds.home.MkdsHomepageActivity#putTextIntoClip

用户昵称

//  com.fenbi.android.module.yingyu.training_camp.home.CampUtils#getUserAccountName
public static String getUserAccountName() {
    String nickName = UserLogic.getInstance().getNickName();
    if (StringUtils.isEmpty(nickName)) {
        return UserLogic.getInstance().getUserAccount();
    }
    return nickName;
}

用户头像.短地址

public static String getNormalImageUrl(String image) {
    if (!TextUtils.isEmpty(image) && image.startsWith("http")) {
        return image;
    }
    return String.format(Locale.getDefault(), "%s/api/images/%s?width=%d&height=%d", KeApiUrl.getCdnRootUrl(), image, NORMAL_SIZE, NORMAL_SIZE);
}

时间格式化

com.fenbi.android.yingyu.home.home.adapter.CetHomeHeaderHolder#renderAppClockIn
com.fenbi.android.yingyu.appsign.AppSignUtil#chartYPopText
com.fenbi.android.yingyu.appsign.learndata.LearnDataActivity#getWatchLectureDurationFormat
每天零时零秒
com.fenbi.android.ke.util.TimeUtils#getDayStart

数据转换

@NonNull
public static long[] toArray(@Nullable List<Long> list) {
    if (ObjectUtils.isEmpty(list)) {
        return new long[0];
    }
    long[] result = new long[list.size()];
    for (int i = 0; i < result.length; i++) {
        result[i] = list.get(i);
    }
    return result;
}
@NonNull
public static List<Long> toList(@Nullable long[] array) {
    if (ObjectUtils.isEmpty(array)) {
        return new ArrayList<>();
    }
    List<Long> list = new ArrayList<>();
    for (long num : array) {
        list.add(num);
    }
    return list;
}

线上日志调试

implementation project(':lib:log-catcher')
Map<String, String> params = new HashMap<>();
params.put("isDestroyed", String.valueOf(isDestroyed()));
params.put("viewName", "lectureBg");
DebugLogger.getInstance().log("destroyed_activity", params, "");
//  重新登录问题
//  * and __topic__ : Login_Fatal and uid: 83383113
DebugLogger.getInstance().log("Login_Fatal", params, "");

数据精确度

四舍五入, 保留小数点后几位
String.format(Locale.getDefault(), "%.0f%%", 100 * data.getRightRatio());
String.format(Locale.getDefault(), "%.0f%%", 100 * data.getWinRate());
全舍
String.format(Locale.getDefault(), "%d%%", (int)(100 * data.getRightRatio()));
格式化数字 万 W  
com.fenbi.android.business.cet.common.utils.RecommendUtil#formatCount

报时器

报时器, 每隔几秒回调一次, 除非主动取消

com.fenbi.android.business.cet.common.logic.TimerLogic

倒计时

com.fenbi.android.business.cet.common.logic.CountDownLogic

失败重试

Observable<RunningStatus> statusObservable = RetrofitUtils.getInstance().getApi(Api.getPath(coursePrefix), Api.class)
        .mkdsStatusInfo(String.valueOf(jamId)).retryWhen(new RetryWhenFunction<>(5, new RunningStatus()));

播放本地视频

com.fenbi.android.module.yingyu.training_camp.summary.adapter.LockableStepViewHolder#playSoundEffect
player.setDateResource("rawresource:///" + R.raw.camp_step_open);

关掉 Native debugger

截图拼接二维码

com.fenbi.android.cet.exercise.history.screenshot.ScreenShotViewModel#concatBitmap

不需要挂在 view 树上

child.measure(View.MeasureSpec.makeMeasureSpec(ScreenUtils.getScreenWidth(), View.MeasureSpec.EXACTLY), View.MeasureSpec.UNSPECIFIED);
child.layout(0, 0, child.getMeasuredWidth(), child.getMeasuredHeight());
Bitmap shotBitmap = PrayDrawShotUtil.shot(shareBinding.bodyView);
doShare(consumer, shotBitmap, path, share, null);

Gson

"userAnswers": {
    "0": {
        "questionId": 4989280,
        "answer": {
            "answer": "",
            "type": 204
        }
    }
}

怎么取最里面的 answer

private JsonElement userAnswers;
final JsonElement jsonElement = exercise.getUserAnswers();
if (jsonElement == null) {
    continue;
}
final JsonElement element = jsonElement.getAsJsonObject().get("0");
if (element == null || ObjectUtils.isEmpty(element.toString())) {
    continue;
}
final WriteAnswerWrapper userAnswer = GsonUtils.fromJson(element.toString(), WriteAnswerWrapper.class);

渲染耗时

long timeMillis = System.currentTimeMillis();
Log.e("LogTrack", "[LogTrack] render.100=" + (System.currentTimeMillis() - timeMillis));

Observable<Object> viewObservable = Observable.create(emitter -> {
    final ViewZip zip = new ViewZip();
    emitter.onNext(zip);
    emitter.onComplete();
}).compose(ViewCreatorDebug.debugLogTransformer()).onErrorReturn(throwable -> new ViewZip());
viewObservable.subscribe(new BaseApiObserver<Object>(lifecycleOwner) {
    @Override
    protected void onSuccessResult(@NonNull Object data) {
        if (BoolUtil.isFalse(data instanceof ViewZip)) {
            return;
        }
        ViewZip zip = (ViewZip) data;
        //  container.removeAllViews();
        //  container.addView();
    }
});
