blocks|key|1212511|text|显然，在onCreate中这样做会破坏应用程序，因为Activity还没有附加到窗口上。如果你这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1212512|@Override
public+void+onAttachedToWindow()+{
++++openOptionsMenu();+
};|code-block|syntax|javascript|1212513|...it起作用了。|1212514|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Apparently, doing it in onCreate breaks app, since Activity's not yet attached to a window. If you do it like so:

<pre><code>@Override
public void onAttachedToWindow() {
 openOptionsMenu(); 
};
</code></pre>

...it works.

blocks|key|998392|text|对于使用Support+Library的新Toolbar类的开发人员，它是这样做的：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|998393|Toolbar+toolbar+=+(Toolbar)+findViewById(R.id.toolbar);
toolbar.showOverflowMenu();|code-block|syntax|javascript|998394|entityMap^0|4|F|L|7|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

For developers using the new <code>Toolbar</code> class of the <code>Support Library</code>, this is how it's done:

<pre><code>Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.showOverflowMenu();
</code></pre>

blocks|key|998205|text|把这行代码放到你的onResume()中，这应该会有帮助！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|998206|new+Handler().postDelayed(new+Runnable()+{+

},+1000);+|code-block|syntax|javascript|998207|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Put this line of code in your onResume(), this should help!

<pre><code>new Handler().postDelayed(new Runnable() { 
 public void run() { 
 openOptionsMenu(); 
 } 
}, 1000); 
</code></pre>

blocks|key|998299|text|从名为MainActivity的活动中的OnClickListener：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|998300|MainActivity.this.openOptionsMenu();|code-block|syntax|javascript|998301|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

from an OnClickListener inside an activity called MainActivity:

blocks|key|998399|text|如果使用AppCompatActivity|type|unstyled|depth|inlineStyleRanges|entityRanges|data|998400|getSupportActionBar().openOptionsMenu();|code-block|syntax|javascript|998401|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

if using AppCompatActivity

<pre><code>getSupportActionBar().openOptionsMenu();

blocks|key|1212362|text|有两种方法可以做到：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1212363|Activity.getWindow().openPanel(Window.FEATURE_OPTIONS_PANEL,+event);|code-block|syntax|javascript|1212364|event参数是一个描述用于打开菜单的键的KeyEvent，它可以根据菜单所来自的键盘类型修改菜单的显示方式。|offset|length|style|CODE|1212365|或者..。通过模拟用户已经按下按钮：|1212366|IWindowManager+wManager+=+IWindowManager.Stub.asInterface(ServiceManager.getService("window"));

Two ways to do it: 

<pre><code>Activity.getWindow().openPanel(Window.FEATURE_OPTIONS_PANEL, event);
</code></pre>

The <code>event</code> argument is a <code>KeyEvent</code> describing the key used to open the menu, which can modify how the menu is displayed based on the type of keyboard it came from. 

Or... by simulating that the user has pressed the button:

<pre><code>IWindowManager wManager = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_SOFT_LEFT);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_SOFT_LEFT);
wManager.injectKeyEvent(kd.isDown(), kd.getKeyCode(), kd.getRepeatCount(), kd.getDownTime(), kd.getEventTime(), true);
</code></pre>

blocks|key|1212630|text|如果您在视图中，则可以编写|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1212631|++++((Activity)getContext()).openOptionsMenu();|code-block|syntax|javascript|1212632|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you are inside an your view, you can write

<pre><code> ((Activity)getContext()).openOptionsMenu();
</code></pre>

blocks|key|998432|text|经过长时间的研究和多次尝试，唯一的方法似乎是模拟KeyEvent。这将使options菜单出现：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|998433|BaseInputConnection+mInputConnection+=+new+BaseInputConnection(+findViewById(R.id.main_content),+true);
KeyEvent+kd+=+new+KeyEvent(KeyEvent.ACTION_DOWN,+KeyEvent.KEYCODE_MENU);
KeyEvent+ku+=+new+KeyEvent(KeyEvent.ACTION_UP,+KeyEvent.KEYCODE_MENU);
mInputConnection.sendKeyEvent(kd);
mInputConnection.sendKeyEvent(ku);|code-block|syntax|javascript|998434|entityMap^0|O|8|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

After a long research and many tries, the only way seems to be simulating a <code>KeyEvent</code>. This makes the options menu appear:

<pre><code>BaseInputConnection mInputConnection = new BaseInputConnection( findViewById(R.id.main_content), true);
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU);
mInputConnection.sendKeyEvent(kd);
mInputConnection.sendKeyEvent(ku);
</code></pre>

blocks|key|998460|text|对我来说，在onClick中声明toolbar.showOverflowMenu()是不可行的。openOptionsMenu()也不适合我。相反，下面的方法对我是有效的，|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|998461|new+Handler().postDelayed(new+Runnable()+{
++++++++++++@Override
++++++++++++public+void+run()+{
++++++++++++++++toolbar.showOverflowMenu();

++++++++},+500);|code-block|syntax|javascript|998462|entityMap^0|G|Q|1C|H|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

For me, declaring <code>toolbar.showOverflowMenu()</code> in onClick is not worked. <code>openOptionsMenu()</code> also not worked for me. Instead of that the following way is worked for me,

<pre><code>new Handler().postDelayed(new Runnable() {
 @Override
 public void run() {
 toolbar.showOverflowMenu();
 }
 }, 500);
</code></pre>

blocks|key|1212743|text|toolbar+=+(Toolbar)+findViewById(R.id.toolbar);

I would like to open the optionsMenu programmatically without a click on the menu key from the user. How would I do that?
