Android - 使用全局异常时无法单击按钮

Question

我在我的 mainactivity 中使用全局异常处理程序，并且我有一些按钮。如果未捕获的异常被调用，则 onclicklistener 按钮不起作用。

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
          @Override
          public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
              Log.e("Alert","Lets See if it Works !!!");

          }
      });
     setContentView(R.layout.activity_graphical_report);

    Button samBtn = findViewById(R.id.imggraphview);

    samBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Intent myIntent = new Intent(MainActivity.this, SecondActivity.class)
            startActivity(myIntent);
        }
    });

}

错误：

谁能帮我解决这个问题。

Answer 1

投射一个可能有问题的按钮

Button samBtn = (Button)findViewById(R.id.imggraphview);

Answer 2

首先设置您的视图。

setContentView(R.layout.activity_graphical_report);
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
          @Override
          public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
              Log.e("Alert","Lets See if it Works !!!");

          }
      });

并且您的按钮不是类型转换的。
