动画菜单项目QUOT;跳跃"当动画开始 [英] Animated menu item "jumps" when animation starts
问题描述
我现在用的是code,从这样一个问题:动画图标ActionItem 来动画我刷新 ActionBarButton
。它工作正常,只是风格似乎并不正确。当我点击该项目时,开始旋转,但只有在它跳了几个像素。这似乎是的ImageView
的风格是从菜单项的风格不同。
I am using the code from this question: Animated Icon for ActionItem to animate my refresh ActionBarButton
. It works fine, except that the style doesn't seem to be right. When I click the item, it starts rotating, but only after it "jumps" a few pixels. It seems like the style of the ImageView
is different from the style of the menu item.
该项目的定义是这样的:
The item is defined like this:
<item
android:id="@+id/action_refresh"
android:orderInCategory="100"
android:icon="@drawable/ic_menu_refresh"
android:showAsAction="ifRoom"
<!-- added this myself, didn't have any effect -->
style="@android:style/Widget.ActionButton"
android:title="@string/action_refresh"/>
和的ImageView
是这样的:
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/action_refresh"
android:src="@drawable/ic_menu_refresh"
style="@android:style/Widget.ActionButton" />
我
如何样式我的菜单项,以匹配的ImageView
在旋转,或者倒过来?
How can I style my menuitem to match the ImageView
in the rotation, or the other way round?
推荐答案
我找到了解决方案,通过设置查看
也非动画的项目是一样的。在 menu.xml文件
:
I found the solution by setting the View
also for the non-animated item to be the same. In the menu.xml
:
<item
android:id="@+id/action_refresh"
android:orderInCategory="100"
android:icon="@drawable/ic_menu_refresh"
android:actionLayout="@layout/refresh_action_view"
android:showAsAction="ifRoom"
style="@android:style/Widget.ActionButton"
android:title="@string/action_refresh"/>
然后,在 onCreateOptionsMenu
,我取的一个成员变量的观点,并附加一个onclick处理程序:
Then, in onCreateOptionsMenu
, I fetch the view in a member variable, and attach an onclick handler:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.orders, menu);
final Menu m = menu;
refreshItem = menu.findItem(R.id.action_refresh);
refreshItem.getActionView().setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
m.performIdentifierAction(refreshItem.getItemId(), 0);
}
});
return true;
}
在的onCreate
,我们载入动画:
rotation = AnimationUtils.loadAnimation(this, R.anim.clockwise_refresh);
rotation.setRepeatCount(Animation.INFINITE);
最后,调用此启动动画:
Finally, call this to start the animation:
refreshItem.getActionView().startAnimation(rotation);
这阻止它:
refreshItem.getActionView().clearAnimation();
