我试图禁用用户拖动BottomSheet.我想禁用的原因是两件事.1.它阻止ListView向下滚动,2.我不希望用户使用拖动但是使用按钮来解除BottomSheetView.这就是我所做的

 bottomSheetBehavior = BottomSheetBehavior.from(bottomAnc);
    bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            if (newState == BottomSheetBehavior.STATE_EXPANDED) {
                //Log.e("BottomSheet", "Expanded");
            } else if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
                //Log.e("BottomSheet", "Collapsed");
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            // React to dragging events
            bottomSheet.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    int action = MotionEventCompat.getActionMasked(event);
                    switch (action) {
                        case MotionEvent.ACTION_DOWN:
                            return false;
                        default:
                            return true;
                    } …

我写了一个自定义ViewPager禁用Swipe Scroll,但我想以编程方式滑动.Tab我的视图寻呼机中有三个,但是当我viewPager.setCurrentItem(viewPager.getCurrentItem()+1)第一个呼叫时Fragment,它会移动到第三个Fragment而不是第二个Fragment.如果我在第二个中调用相同的函数Fragment,则会转到第三个函数.如果我在第三个片段中调用(viewPager.getCurrentItem() - 1)`,它可以通过向后移动来正常工作.任何帮助,将不胜感激.我的代码如下:

NonSwipeAbleViewPager

public class NonSwipeableViewPager extends ViewPager {

private boolean swipeable;

public NonSwipeableViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.MyViewPager);
    try {
        swipeable = a.getBoolean(R.styleable.MyViewPager_swipeable, true);
    } finally {
        a.recycle();
    }
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    return swipeable ? super.onInterceptTouchEvent(event) : false;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    return swipeable ? super.onTouchEvent(event) : false; …

我想inject dependencies进入我的应用程序.一切都很好,直到我试着注入Realm我的Service班级.我开始得到IllegalStateException这显然是由我Realm从Thread它创建的访问引起的.所以,这是我的结构Dependency Injection

AppModule

@Module
public class AppModule {

    MainApplication mainApplication;

    public AppModule(MainApplication mainApplication) {
        this.mainApplication = mainApplication;
    }

    @Provides
    @Singleton
    MainApplication getFmnApplication() {
        return mainApplication;
    }
}

RequestModule

public class RequestModule {

    Retrofit.Builder getRetrofitBuilder() {
        return new Retrofit.Builder()
                .baseUrl(BuildConfig.HOST)
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create(CustomGsonParser.returnCustomParser()));
    }

    @Provides
    @Singleton
    OkHttpClient getOkHttpClient() {
        return new OkHttpClient.Builder()
                .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BASIC))
                .connectTimeout(30000, TimeUnit.SECONDS)
                .readTimeout(30000, TimeUnit.SECONDS).build();
    }

我试图在其中Long使用价值，Android Databinding但无法使其发挥作用。这就是我尝试过的一切

1：效果很好。直到我开始对棒棒糖之前的产品进行测试并且开始遇到崩溃。我不得不android:addTextChangedListener="@{outlet.onCapacityChange}"从XML中删除它

    Java
    @SerializedName("capacity")
    @Expose
    Long capacity
    /**
     * 
     * @return
     *     The capacity
     */
    @Bindable
    public Long getCapacity() {
        return capacity;
    }

    /**
     * 
     * @param capacity
     *     The capacity
     */
    public void setCapacity(Long capacity) {
        setAtomicCapacity(capacity);
        Log.e(TAG+"Capacity", "" + capacity);
        notifyPropertyChanged(BR.capacity);
    }

    public void setAtomicCapacity(Long basic) {
        this.capacity = basic;
    }

    public TextWatcher onCapacityChange = new SimpleTextWatcher() {
        @Override
        public void onTextChanged(String newValue) {
            Log.e(TAG+"Capacity", newValue);
            setAtomicCapacity(Long.valueOf(newValue));
        }

我试图让Viper读取我的环境变量,但它无法正常工作.这是我的配置:

# app.yaml
dsn: RESTFUL_APP_DSN
jwt_verification_key: RESTFUL_APP_JWT_VERIFICATION_KEY
jwt_signing_key: RESTFUL_APP_JWT_SIGNING_KEY
jwt_signing_method: "HS256"

我的config.go档案:

package config

import (
    "fmt"
    "strings"

    "github.com/go-ozzo/ozzo-validation"
    "github.com/spf13/viper"

// Config stores the application-wide configurations
var Config appConfig

type appConfig struct {
    // the path to the error message file. Defaults to "config/errors.yaml"
    ErrorFile string `mapstructure:"error_file"`
    // the server port. Defaults to 8080
    ServerPort int `mapstructure:"server_port"`

我试图实现一个我在草图上嘲笑的观点.我在Android上复制了它,因为我在这个平台上非常好.我在iOS上很擅长,但UI是我的弱点.

我扩展了一个UIViewController和我的StoryBoard有顶部是一个视图,底部是一个tableview.我遇到的问题是UITableViewCell在应用程序本身中看起来像这样.以下是我尝试过的解决方案.但是,它只是把它全部挤到了顶端.NB.我用UIView它画出那些小小的线条UITableViewCell

func configureTableView() {
    //First One I tried then later commented it out
    loanStateTable.rowHeight = UITableViewAutomaticDimension
    loanStateTable.scrollToNearestSelectedRowAtScrollPosition(UITableViewScrollPosition.Middle, animated: true)

    //Second One I tried
    var edgeInset = UIEdgeInsets(top: 16, left: 16, bottom: 0, right: 16)
    loanStateTable.contentInset = edgeInset
}

和故事板视图

任何帮助,将不胜感激.谢谢

输出:

从我的表中的一列中，我想获得这些列中值类型的总和计数。例如，一列是：

|paymentGateway |
---------------
|   Paystack    |
|   Flutterwave |
|   NIBSS       |
|   PAGA        |
|   Interswitch |

|   Paystack    |
|   Flutterwave |
|   NIBSS       |
|   PAGA        |

我运行了查询Progress DB Viewer，它工作正常。这是查询：

  SUM(1) FILTER (WHERE "paymentGateway" = 'Paystack') AS paystack,
  SUM(1) FILTER (WHERE "paymentGateway" = 'NIBSS') AS nibss,
  SUM(1) FILTER (WHERE "paymentGateway" = 'Flutterwave') AS flutterwave, …

我试图将更新发送到我Activity从我的GCMServiceListener话,我使用RxJava/RxAndroid并创建一个BusClass用于处理和发送Observers

public class ClientBus {

//private final PublishSubject<Object> _bus = PublishSubject.create();

// If multiple threads are going to emit events to this
// then it must be made thread-safe like this instead
private final Subject<Object, Object> _bus = new SerializedSubject<>(PublishSubject.create());

public void send(Object o) {
    _bus.onNext(o);
}

public Observable<Object> toObserverable() {
    return _bus;
}

public boolean hasObservers() {
    return _bus.hasObservers();
}
}

而在我,Application Class我这样做初始化BusClass

private ClientBus clientBus;
