当我实现方法setSupportActionBar时，我的应用程序崩溃了

嗯，问题是，如果我从add_event活动中删除了setSupportActionBar（工具栏），它就可以了，add_event活动会打开并显示屏幕上的所有按钮和textEdits，但是不要在工具栏上显示任何按钮，只是工具栏，干净，如果我把那个setSupportActionBar方法，它在我调用活动时崩溃（add_event）。

有人可以解释发生了什么事吗？在此先感谢：）

我在这里放了一些代码，但是你们可以在我的GitHub中下载整个项目

https://github.com/dennysfarias/RemindIt 

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //setting toolbar
    Toolbar toolbar = (Toolbar)findViewById(R.id.my_toolbar);
    setSupportActionBar(toolbar);
}


public void callactAddEvt(){
    Intent callAddEvt = new Intent(MainActivity.this, add_event.class);
    MainActivity.this.startActivity(callAddEvt);
}

@Override
public boolean onCreateOptionsMenu(Menu menu){
    getMenuInflater().inflate(R.menu.menu, menu);
    return true;
}


//put the options inside the 3dot menu
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_settings:
            // User chose the "Settings" item, show the app settings UI...
            Toast.makeText(getApplicationContext(), "Settings Option Pressed", Toast.LENGTH_SHORT).show();
            return true;

        case R.id.action_addevent:
            //User chose the AddEvent action, whom calls the com.ddtec.remindit.add_event activity
            callactAddEvt();
            Toast.makeText(getApplicationContext(), "Add Event Option Pressed", Toast.LENGTH_SHORT).show();

            return true;
        default:
            // If we got here, the user's action was not recognized.
            // Invoke the superclass to handle it.
            Toast.makeText(getApplicationContext(), "No Option Pressed", Toast.LENGTH_SHORT).show();

            return super.onOptionsItemSelected(item);

    }
}
}

这是我的MainActivity它工作正常，我在手机上尝试这个，它看起来很棒。

现在我要展示我的第二项活动

public class add_event extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.add_event);

    Toolbar toolbar = (Toolbar)findViewById(R.id.my_toolbar2);
    setSupportActionBar(toolbar);
}


@Override
public boolean onCreateOptionsMenu(Menu menu){
    getMenuInflater().inflate(R.menu.menu_add_event, menu);
    return true;
}




@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_addfinish:
            // User chose the Done action, saving the event...
            Toast.makeText(getApplicationContext(), "Finish/Save Option Pressed", Toast.LENGTH_SHORT).show();

            return true;

        case R.id.action_cancel:
            // User chose the Cancel action, leaving without saving the current event...
            Toast.makeText(getApplicationContext(), "Cancel Option Pressed", Toast.LENGTH_SHORT).show();

            return true;

        case R.id.action_settings:
            Toast.makeText(getApplicationContext(), "Settings Option Pressed", Toast.LENGTH_SHORT).show();

            return true;


        default:
            // If we got here, the user's action was not recognized.
            // Invoke the superclass to handle it.
            Toast.makeText(getApplicationContext(), "No Option Pressed", Toast.LENGTH_SHORT).show();

            return super.onOptionsItemSelected(item);

    }
}
}
