当我实现setSupportActionBar方法时，我的应用程序崩溃了
当我实现setSupportActionBar方法时，我的应用程序崩溃了
提问于 2016-04-28 13:59:10
问题是，如果我将setSupportActionBar (工具栏)从add_event活动中删除，它就会正常工作，add_event活动会打开并显示屏幕上的所有按钮和textEdits，但不会在工具栏上显示任何按钮，只显示工具栏上的任何按钮，而如果我将该setSupportActionBar方法放入其中，当我调用活动(add_event)时，它会崩溃。
有人能解释一下发生了什么吗？(预先谢谢:)
我在这里放了一些代码，但是你们可以在我的GitHub里下载整个项目
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 --它工作得很好，我在我的手机上试了一下，它看起来很棒。
现在我要展示我的第二次活动
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);
}
}

在您的menu_add_event.xml在线编号:13中，您添加了“android:onClick=”“ClearAll”。这就是问题的根源。要么删除该行，要么在活动中添加以下函数。
public boolean ClearAll(MenuItem item) {
// actions
