我不知道为什么会这样。

Answer 1

从here

尝试此操作

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ( keyCode == KeyEvent.KEYCODE_MENU ) {
        // do nothing
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

Answer 2

也许你需要getSupportActionbar（）而不是getActionbar（）

Answer 3

我已经研究过这个问题，发现这个问题是android OS的问题，并且在values/styles删除下面的代码中解决了这个问题：

<item name="android:fontFamily">every things here</item>

Answer 4

IF您的EditText用TextInputLayout包裹起来，这可能对您有帮助

为TextInputLayout分配了theme，请确保其父级为

parent="Widget.Design.TextInputLayout"

这是我的问题，更换父母后，它开始正常工作。

Answer 5

下面是对我有用的...

1）如果您的EditText用 TextInputLayout 包装，则将以下属性添加到您的Edittext

android：longClickable = false

2）如果您为EditText使用自定义样式，则将以下属性添加到自定义样式代码中。

<item name="android:longClickable">false</item>

希望这会有所帮助。
