Java 单击按钮时应用程序关闭

我在android project中编写了这段代码，用于打开一个新视图，但每当单击按钮时，应用程序就会停止工作，但在调试器控制台上不会返回任何错误。除了说应用程序关闭的日志

这是我的密码

public class LoginActivity extends Activity{
    private Button btnLinkToRegister;
    btnLinkToRegister = (Button) findViewById(R.id.btnLinkToRegisterScreen);  

     // Link to Register Screen
    btnLinkToRegister.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            Intent i = new Intent(getApplicationContext(),
                    RegisterActivity.class);
            startActivity(i);
            finish();
        }
    });
}

我已经删除了其他代码，以便于识别问题

尝试在onClick方法中使用此选项：

Intent i = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(i);
finish();

还可以在Maniffest文件中添加RegisterActivity。

您可以共享您的logcat吗？现在您会得到一大堆猜测作为答案，因为logcat不包括在问题中（logcat会告诉您问题的根本原因），我已经添加了JU，请不要使用即时运行并重试。您发布的代码删掉了太多内容，无法像这样编译注册活动就在那里
