我有一个Android应用。我使用Android Studio。在添加与崩溃位置无关的代码之前，此应用程序正在运行。我在前几行放置了断点。当我启动调试器时，前两行正确停止，但在进入下一个语句之前崩溃。由于这部分代码没有改变，我不知道它为什么会崩溃。有人可以建议寻找一些东西吗？
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
// Set up the login form.
mEmailView = (AutoCompleteTextView) findViewById(R.id.email);
populateAutoComplete();
这是XML：

答案 0 :(得分：0)
我会尝试使用以下代码更改代码，将EditText的任何实例封装到单个TextInputLayout中，因为您获得了以下stacktrace行：
