java - Android studio 应用程序不断关闭

Question

好吧，我是 Android 工作室的新手，我正在摆弄一个愚蠢的放屁噪音应用程序。我的第一次尝试是一个发出噪音的按钮，现在我有三个按钮，但应用程序无法在模拟器中打开。它只说应用程序不断关闭。我尝试用谷歌搜索日志猫中的每个错误，但到目前为止没有任何效果。我尝试了几个不同的模拟器，但最初它可以工作，所以不知道要改变什么。声音文件是 .mp3 不确定这是否重要。

这是我的日志猫

Answer 1

您初始化按钮的方式是错误的。这是初始化 View 的正确方法:

button1 = (Button)findViewById(R.id.button1);
button2 = (Button)findViewById(R.id.button2);
button3 = (Button)findViewById(R.id.button3);
