kivy gridlayout中的按钮位置

Question

我正在尝试将此按钮移到右上角，但无论我做什么我都无法移动它。它总是在左下角并且永远不会离开这个位置。

这是我的.py:

    #!/usr/bin/python
    # coding=UTF-8

    import kivy
    from kivy.uix.gridlayout import GridLayout
    from kivy.app import App
    from kivy.uix.button import Button
    from kivy.lang import Builder

    Builder.load_file('listadex.kv')

    class TestS(GridLayout):
        def bt1(self):
            print 'Olar galera'        #layout.add_widget(bt1.Button(text='TestS'))

    class SegundaTela(App):
        def build(self):
    #layout = GridLayout(cols=2, row_force_default=False, row_default_height=10)
    #layout.add_widget(bt1.Button(text='TestS'))
    #layout.add_widget(bt2.Button(text='TestA'))
    #layout.add_widget(bt3.Button(text='TestD'))
    #layout.add_widget(bt4.Button(text='TestMC'))
    #return layout
    CF = TestS()
    return CF

    SegundaTela().run()

这是我的 .kv

    <TestS>:
        GridLayout:
            rows: 1
            cols: 1
            padding: 3
            spacing: 3

            Button:
                text: 'botao1'
                on_press: root.bt1()
                pos_hint: {'center_x':.15}

Answer 1

我建议使用相对布局。例如

RelativeLayout:

    Button:
        text: 'botao1'
        on_press: root.bt1()
        pos_hint: {'center_x': 0.5, 'center_y': 0.5}

更改center_x和center_y直到它们满足您的需求。
