我使用以下代码使用滑动将带圆角的图像加载到imageview中:

Glide.with(this)
                .load(url)
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                        return false;
                    }
                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                        return false;
                    }
                })
                .transition(withCrossFade())
                .apply(new RequestOptions().transform(new RoundedCorners(50)).error(R.drawable.default_person).skipMemoryCache(true).diskCacheStrategy(DiskCacheStrategy.NONE))
                .into(mBinding.profileImgv);

由于某种原因,图像被像素化.有人能告诉我问题出在哪里吗？

我有一个片段的活动.我正在尝试注入片段,但我得到'没有找到com.tsiro.dogvip.login.signin.SignInFrgmt'的例子.

ActivityModule:

@Module(includes = BaseActivityModule.class)
public abstract class LoginActivityModule {

   @PerFragment
   @ContributesAndroidInjector(modules = SignInFragmentModule.class)
   abstract SignInFrgmt signInFrgmtInjector();

   @Binds
   @PerActivity
   abstract Activity activity(LoginActivity loginActivity);
}

FragmentModule:

@Module(includes = BaseFragmentModule.class)
public abstract class SignInFragmentModule {

@Binds
@Named(BaseFragmentModule.FRAGMENT)
@PerFragment
abstract Fragment fragment(SignInFrgmt signInFrgmt);

}

Fragment类扩展了BaseFragment,其中实现了HasSupportFragmentInjector.

BaseFragment:

public abstract class BaseFragment extends Fragment implements HasSupportFragmentInjector, Lifecycle.View {

@Inject
DispatchingAndroidInjector<Fragment> fragmentInjector;
public abstract Lifecycle.ViewModel getViewModel();

@SuppressWarnings("deprecation")
@Override
public void onAttach(Activity activity) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
        // Perform injection here before M, L (API …

这是 forkJoin 运算符 jasmine 大理石测试：

it('test1', () => {

 const a = cold('---a|', { a: 1 });
 const b = cold('---b|', { b: 2 });

 const observable = forkJoin(
   a,
   b
 );

 const expected = cold('---21');
 expect(observable).toBeObservable(expected);
});

测试产生以下错误：

Expected $[0].frame = 40 to equal 30.
Expected $[0].notification.value = [ 1, 2 ] to equal '2'.
Expected $[1].frame = 40 to equal 50.
Expected $[1].notification.kind = 'C' to equal 'N'.
Expected $[1].notification.value = undefined to equal '1'.
Expected $[1].notification.hasValue = …

我正在使用webpack 4捆绑应用程序资源。

tsconfig.json：

    ]
  },
    "compileOnSave": true,
    "exclude": [
       "node_modules"    
    ]
}

module.exports = require("./config/webpack.dev.js");

我正在使用angularjs(1.5.8)框架与最新的打字稿(2.8.0)文件.更新到最新的打字稿版本后,不会编译以下代码.

角度接口实现:

interface IPromise<T> {
    /**
     * Regardless of when the promise was or will be resolved or rejected, then calls one of the success or error callbacks asynchronously as soon as the result is available. The callbacks are called with a single argument: the result or rejection reason. Additionally, the notify callback may be called zero or more times to provide a progress indication, before the promise is resolved or rejected.
     * The successCallBack may return IPromise<void> for when …

我想要实现的是移动div项目,当点击每个项目时,它被点击在div容器的顶部...其余的项目(那些没有被点击的)将填充div的其余部分容器分别

HTML

    <div class="row">
        <div class="col-md-12">
            <div class="containing_div">
                <div class="container_div"></div>
                <div class="menu_div">
                    <div class="item_div">Photos</div>
                    <div class="item_div">Video</div>
                    <div class="item_div">Music</div>

任何人都可以向我解释Perl中以下结构之间的区别是什么:

$VAR = {"user" => "text", "id" => "textid"};

$VAR = {"user" : 4, "code" : "codetext"};

我如何访问每个结构的值？

我在我的应用程序中使用 Angular 反应形式。我想为多选表单控件设置多个值。

mycomponent.html

<select id="placeType" 
        class="form-control" 
        [multiple]="true" 
        style="height:200px" 
        formControlName="kalase">
  <option value="" selected="selected" disabled>Select Place Type</option>
  <option *ngFor="let kalase of types" [value]="kalase" [innerHtml]="kalase"></option>      
</select>

mycomponent.ts

types: string[] = ["BAR", "CAFE", "RESTAU", "hotels", "club"];

this.placeForm = this.formBuilder.group({
  kalase: [[this.types[1], this.types[3]]]
});

问题是选择控件中唯一选定的值是类型数组的第四项（“hotels”）。谁能告诉我我做错了什么？

我有以下结构,它在变量my @json_device = getDeviceId($ Session - > {id})中返回;

正在显示的结构如下

$VAR1 = [{"device_name":"device1","device_id":"device_id1"},{"device_name":"device2","device_id":"device_id2"}]

我使用以下代码迭代数组引用并获取"device_name"和"device_id"值

 for my $aref (@json_device){
        for my $href (@$aref){
            warn $href->{device_name};
            warn $href->{device_uuid};
        }
    }

但我得到以下的错误不能使用字符串("[{"device_name":"iPhone Simulato"...)作为ARRAY参考,而使用"严格参考"任何人都可以向我解释出现了什么问题？
