Question

我在tablayout的活动中定义了view pager和tablayout，我正在显示点指示器。尽管它工作正常，但我想缩小tablayout和view pager之间的差距。

布局文件

  <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="130dp"
        android:layout_marginTop="5dp"
        android:id="@+id/homeOffers"/>

    <android.support.design.widget.TabLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/indicator"
        app:tabGravity="center"
        app:tabIndicatorHeight="0dp"
        app:tabBackground="@drawable/tab_selector"/>

    </LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">

<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="130dp"
    app:contentPadding="3dp"
    app:cardCornerRadius="3dp"
    app:cardBackgroundColor="#fff"
    app:cardUseCompatPadding="true">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/offerImage"
    android:scaleType="fitXY"/>

</android.support.v7.widget.CardView>

</LinearLayout>

请让我知道如何实现所需的布局。任何帮助将不胜感激。

谢谢

像这样使用RelativeLayout-

begin
   using FFTW
   using DifferentialEquations
   using PyPlot
end

begin
   n = 512
   L = 200
   n2 = Int(n/2)
   alpha = 2im
   beta = 1im
   x = range(-L/2,stop=L/2,length=n)
   u0 = 0.01*(rand(ComplexF64, n) .- 0.5)

   k = [0:n/2-1; 0; -n/2+1:-1] .*(2*pi/L);
   k2 = k.*k
   k2[n2 + 1] = (n2*(2*pi/L))^2 

   T = plan_fft(u0)
   Ti = plan_ifft(T*u0)

   LinOp = (1.0 .- k2.*(1.0 .+alpha))
   Fu0 = T*u0
end

function cgle!(du, u, p, t)
    LinOp, b, T, Ti = p

    invu = Ti*u
    du .= LinOp.*u .- T*( (1.0 .+b) .* (abs.(invu)).^2 .* invu)
end

pars = LinOp, beta, T, Ti
prob = ODEProblem(cgle!, Fu0, (0.,100.), pars)
@time u = solve(prob)

t = collect(range(0, stop=50, length=1000))
sol = zeros(eltype(u),(n, length(t)))
for it in eachindex(t)
   sol[:,it] = Ti*u(t[it])
end

IM = PyPlot.imshow(abs.(sol))
cb = PyPlot.colorbar(IM, orientation="horizontal") 
gcf()

然后从您的卡片视图中删除此行-

 <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

  <android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="130dp"
    android:layout_marginTop="5dp"
    android:id="@+id/homeOffers"/>

  <android.support.design.widget.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/indicator"
    app:tabGravity="center"
    app:tabIndicatorHeight="0dp"
    app:tabBackground="@drawable/tab_selector"
    android:layout_below="@id/homeOffers/>

 </RelativeLayout>
