该应用无法运行

标签: android-studio android-studio-3.0

我正在使用CourtCounter应用程序,但我有3个错误 1)当你试图为Peat添加一个点时,它不起作用。所有积分都是针对Marta的账户 2)当我按下Reset按钮时,整个应用程序正在重启(只是它正在停止)。我认为应该重新启动结果 3)背景图像 - 正如你所看到的,它被扩展了。它看起来并不好看。我想我只需要使用尺寸合适的专用于手机的图片? enter image description here

任何人都可以帮助我吗? 我没有把错误看成代码。我不知道它为什么不起作用。

1 个答案:

答案 0 :(得分:0)

1)在Peat团队的按钮中,onClick属性正在使用A队的方法。

2)您的重置按钮的onClick属性引用了一个名为ResetScore的方法,但您在代码中定义的方法名为resetScore(请注意小写的“r”)。这会导致您的应用崩溃。

3)您可能希望使用其他图像,或者,如果切换到使用android:src属性,则可以使用android:scaleType属性控制图像的缩放。
