我将最后登录时间存储在MySQL中的datetime-type字段中.当用户登录时,我想获得上次登录时间和当前时间(我使用的NOW())之间的差异.
我怎么计算呢？
我使用以下:
replace (str1.begin(), str1.end(), 'a' , '')
但这会导致编译错误.
当前代码:
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constant.BASEURL)
.addConverterFactory(GsonConverterFactory.create())
.build();
APIService service = retrofit.create(APIService.class);
Call<ResponseWrap> call = service.getNewsData();
call.enqueue(new Callback<ResponseWrap>() {
@Override
public void onResponse(Call<ResponseWrap> call1, Response<ResponseWrap> response) {
if (response.isSuccess()) {
ResponseWrap finalRes = response.body();
for(int i=0; i<finalRes.getResponse().getResults().size(); ++i){
String title = finalRes.getResponse().getResults().get(i).getWebTitle();
News n = new News(titleCategory, title, null);
newsList.add(n);
}
AdapterRecommendation adapter = new AdapterRecommendation(getApplicationContext(), newsList);
listView.setAdapter(adapter);
}
else{
Toast.makeText(getApplicationContext(), "onResponse - something wrong" + response.message(), Toast.LENGTH_LONG).show();
}
}
@Override
public void onFailure(Call<ResponseWrap> call1, Throwable t) {
Toast.makeText(getApplicationContext(), …我正在尝试使用AngularJS上传文件.这是我的代码:
HTML
<input type="file" file-model="myFile"/>
<button ng-click="uploadFile()">upload me</button>
JavaScript的
$scope.uploadFile = function(){
var file = $scope.myFile;
var uploadUrl = "http://admin.localhost/images/patanjali/";
VariantService.uploadFileToUrl(file, uploadUrl);
};
VariantService.uploadFileToUrl = function(file, uploadUrl){
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
alert ('success');
})
.error(function(){
});
}
虽然我可以在我的服务中看到("成功")警报,但该文件未保存在控制器中提供的位置.
有人能帮我吗？缺什么？
我有一个文本框.
<input type="text" ng-model="SearchText" >
和链接
<a href="#signout" ng-click="SearchText=''">Sign out</a>
我想在上面的超链接中进行论述.ng-click清空文本框,#signout并将ng-route注销HTML和控制器.
但我可以ng-click在Angular.js中看到href覆盖
如何执行？
我正在按照本教程将Dagger 2添加到我的Android项目中.
在设置并创建模块和组件之后,我可以在Activity中添加依赖项,如下所示:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account);
ButterKnife.bind(this);
((AppController) getApplication()).getNetComponent().inject(this);
}
我正在努力如何在Fragment和IntentService中注入依赖项？
public class FragmentBrandList extends ListFragment {
}
在这个类中,@Override我应该请求注入哪个方法以及这个代码是什么？
这是我的活动中onCreate函数的实现.我需要动态创建标签.为简单起见,我制作了两个标签.
public class ActivityProductList extends AppCompatActivity {
private android.support.v7.widget.SearchView searchView = null;
private RecyclerView recyclerView;
MyAdapter adapter;
List<ParentListItem> parentListItems = new ArrayList<>();
List<ParentListItem> originalProductList = new ArrayList<>();
String query = null;
int categoryId = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_products_final);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("PRODUCTS");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
//setupViewPager(viewPager);
//tabLayout.setupWithViewPager(viewPager);
//viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
searchView = (android.support.v7.widget.SearchView) findViewById(R.id.searchView);
searchView.setIconified(false);
searchView.onActionViewExpanded();
searchView.clearFocus();
searchView.setOnQueryTextListener(new android.support.v7.widget.SearchView.OnQueryTextListener() {
@Override …这是我的页面布局.
<div layout="column" layout-fill ng-controller="MainCtrl as mc">
<header>
<md-toolbar md-scroll-shrink>
<div layout="row" layout-align="center center" flex>
HEADER INFO
</div>
</md-toolbar>
</header>
<main>
<div ui-view>
</div>
</main>
<footer>
<md-toolbar class="md-scroll-shrink">
<div layout="row" layout-align="center center" flex>
FOOTER INFO
</div>
</md-toolbar>
</footer>
</div>
目前页脚正在主要内容之后显示.取决于显示屏幕中间某处或页面高度以下的主要页脚大小.
我希望页脚始终固定在屏幕的底部.并且根据main的大小,主要内容中应该有一个滚动.
谁可以帮我这个事？
这是一些示例JSON数据.
$scope.Products = [
{
"Variants": [],
"SubCategoryID": "66",
"ProductImagePath": "/images/britannia/887.png",
"SubCategoryName": "Butter",
"BrandName": "Britannia",
"ProductID": "887",
"BrandID": "76",
"ProductName": "Butter"
},
{
"Variants": [],
"SubCategoryID": "71",
"ProductImagePath": "/images/amul/886.png",
"SubCategoryName": "Cheese",
"BrandName": "Amul",
"ProductID": "886",
"BrandID": "47",
"ProductName": "cheese"
},
{
"Variants": [],
"SubCategoryID": "106",
"ProductImagePath": "/images/amul/885.png",
"SubCategoryName": "Curd",
"BrandName": "Amul",
"ProductID": "885",
"BrandID": "47",
"ProductName": "curd"
}
]
这就是我如何渲染到网页.
<div ng-if="SearchText" class='box' ng-repeat="product in Products | filter:FilterExpr | orderBy:'ProductName'">
<ng-include src="'commonTemplate.html'"></ng-include>
</div>
页面中有一个搜索文本框.当用户开始在serach文本框中输入时,我会像这样为FilterExpr分配值.
$scope.$on('SearchTextChanged', function(event, SearchText) {
if (SearchText.length …我有4张桌子.
