动画菜单项目QUOT;跳跃＆QUOT;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();
