Java 扩展应用紧性会产生未捕获的异常

在MainActivity中，当我按下按钮时，我必须打开另一个扩展AppCompacActivity的活动。问题是，由于一个未处理的异常，我使我的应用程序崩溃。这是密码

main程序代码：

Button NextButton = (Button)findViewById(R.id.next_button);
    NextButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getApplicationContext(), GeofenceMainActivity.class);
            startActivity(intent);
        }
    });

尝试在清单中添加此主题：

android:theme="@style/Theme.AppCompat" >

在

活动中

标记

 <activity
        android:name=".GeofenceMainActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat" />

post完整的logcat stacktrace..调用super onCreate（）并在第二个活动的onCreate（）方法中将savedInstanceState传递给它。@DushyantSuthar，代码已经完成了。无论如何，我已经在这里添加了那个片段。@rafsanahmad007我的问题是我不能有任何例外。我试图在所有onCreate方法中放置一个try/catch块，但是什么也没有发生，因为异常结果仍然未捕获。我没有把stacktrace放在这里，因为我没有它。你确定吗？因为我在你添加的代码中看不到它。
