问题描述
所以,我一直在寻找在谷歌的API演示,动作条,他们有这种
So I was looking at google's api demos for action bars and they have this
// The Action Bar is a window feature. The feature must be requested
// before setting a content view. Normally this is set automatically
// by your Activity's theme in your manifest. The provided system
// theme Theme.WithActionBar enables this for you. Use it as you would
// use Theme.NoTitleBar. You can add an Action Bar to your own themes
// by adding the element <item name="android:windowActionBar">true</item>
// to your style definition.
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
但是,当我试图加code中的最后一行 getWindow()requestFeature(Window.FEATURE_ACTION_BAR);
我的应用程序只是死在启动。那么什么是真的?
but when I tried to add the last line of code getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
My app just dies on start up. So what does it really do?
推荐答案
秘诀是callings.The requestfeature必须之前调用补什么的顺序。我这样做是在这个秩序和正常工作:
The secret is the order of the callings.The requestfeature must be called before fill nothing. I do it in this order and works fine:
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.your_activity_layout);
