Android中封装网络请求时的提示框

Android中封装网络请求时的提示框

关键代码

/**
 * 显示加载对话框
 */
public void showLoading() {
    showLoading(getString(R.string.loading));
}

/**
 * 显示加载对话框
 */
public void showLoading(int data) {
    showLoading(getString(data));
}

/**
 * 显示加载对话框
 */
public void showLoading(String message) {
    if (loadingWeakReference == null || loadingWeakReference.get() == null) {
        loadingWeakReference = new WeakReference<>(
                SuperRoundLoadingDialogFragment.newInstance(message)
        );
    }

    SuperRoundLoadingDialogFragment dialog = loadingWeakReference.get();
    if (dialog.getDialog() == null || !dialog.getDialog().isShowing()) {
        dialog.show(getSupportFragmentManager(), "SuperRoundLoadingDialogFragment");
    }
}

/**
 * 隐藏加载对话框
 */
public void hideLoading() {
    SuperRoundLoadingDialogFragment dialog = loadingWeakReference.get();
    if (dialog != null) {
        dialog.dismiss();
        loadingWeakReference.clear();
    }
    loadingWeakReference = null;
}

public HttpObserver(BaseLogicActivity activity, boolean isShowLoading) {
    super();
    this.activity = activity;
    this.isShowLoading = isShowLoading;
}
/**
 * 请求结束，成功失败都会调用（调用前调用），使用在这里隐藏加载提示
 */
public void onEnd() {
    if (isShowLoading) {
        activity.hideLoading();
    }

}

/**
 * 开始网络请求前
 *
 * @param d
 */
@Override
public void onSubscribe(Disposable d) {
    super.onSubscribe(d);

    if (isShowLoading) {
        //显示加载对话框
        activity.showLoading();
    }
    if(getPlaceholderView()!=null){
        SuperViewUtil.gone(getPlaceholderView());
    }

}

使用

 DefaultRepository.getInstance()
                .sheetDetail(id)
                .to(autoDisposable(AndroidLifecycleScopeProvider.from(this)))
                .subscribe(new HttpObserver<DetailResponse<Sheet>>(getHostActivity(), true) {
                    @Override
                    public void onSucceeded(DetailResponse<Sheet> data) {
                        showData(data.getData());
                    }
                });

​ 通过new HttpObserver<DetailResponse>(getHostActivity(), true) 这个boolean值判断是否显示加载提示框
