我有以下完美的代码。但是我无法解决的一个问题是，当Titles上的import SwiftUI
struct CustomSegmentedPickerView: View {
@State private var selectedIndex = 0
private var titles = ["Round Trip", "One Way", "Multi-City", "Other"]
private var colors = [Color.red, Color.green, Color.blue, Color.yellow]
@State private var frames = Array<CGRect>(repeating: .zero, count: 4)
var body: some View {
VStack {
ScrollView(.horizontal, showsIndicators: false) {
ZStack {
HStack(spacing: 10) {
ForEach(self.titles.indices, id: \.self) { index in
Button(action: { self.selectedIndex = index }) {
Text(self.titles[index])
}.padding(EdgeInsets(top: 16, leading: 20, bottom: 16, trailing: 20)).background(
GeometryReader { geo in
Color.clear.onAppear { self.setFrame(index: index, frame: geo.frame(in: .global)) }
})
}
}
.background(
Capsule().fill(self.colors[self.selectedIndex].opacity(0.4))
.frame(width: self.frames[self.selectedIndex].width,
height: self.frames[self.selectedIndex].height, alignment: .topLeading)
.offset(x: self.frames[self.selectedIndex].minX - self.frames[0].minX)
, alignment: .leading
)
}
.animation(.default)
.background(Capsule().stroke(Color.gray, lineWidth: 3))
Picker(selection: self.$selectedIndex, label: Text("What is your favorite color?")) {
ForEach(0..<self.titles.count) { index in
Text(self.titles[index]).tag(index)
}
}.pickerStyle(SegmentedPickerStyle())
Text("Value: \(self.titles[self.selectedIndex])")
Spacer()
}
}
}
func setFrame(index: Int, frame: CGRect) {
self.frames[index] = frame
}
}
struct CustomSegmentedPickerView_Previews: PreviewProvider {
static var previews: some View {
CustomSegmentedPickerView()
}
}
在滚动视图中特别可见并且用户单击可见的文本部分时，我不仅要选择标题我希望scollview能够“自动滚动”，以便完整标题显示在滚动视图中，而只显示部分文本。
from tendo import singleton
try:
me = singleton.SingleInstance()
except:
print("Already running")
sys.exit(-1)
