我在标签主机中为片段/标签添加了动画,就像这里一样:https://stackoverflow.com/a/12109268/1865583
但动画才刚开始......我尝试使用startAnimation,但也没有效果......?
这是在我父片段的onCreateView方法中添加的,它有mTabHost字段...
//On tab changed
mTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
logInfo("Tab changed id " + tabId);
currentView = mTabHost.getCurrentView();
if (mTabHost.getCurrentTab() > currentTab)
{
previousView.setAnimation(outToLeftAnimation());
currentView.setAnimation(inFromRightAnimation());
}
else
{
previousView.setAnimation(outToRightAnimation());
currentView.setAnimation(inFromLeftAnimation());
}
previousView = currentView;
currentTab = mTabHost.getCurrentTab();
}
});
/**
* Custom animation that animates in from right
*
* @return Animation the Animation object
*/
private Animation inFromRightAnimation()
{
Animation inFromRight = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 1.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f);
return setProperties(inFromRight);
}
/**
* Custom animation that animates out to the right
*
* @return Animation the Animation object
*/
private Animation outToRightAnimation()
{
Animation outToRight = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f);
return setProperties(outToRight);
}
/**
* Custom animation that animates in from left
*
* @return Animation the Animation object
*/
private Animation inFromLeftAnimation()
{
Animation inFromLeft = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f);
return setProperties(inFromLeft);
}
/**
* Custom animation that animates out to the left
*
* @return Animation the Animation object
*/
private Animation outToLeftAnimation()
{
Animation outtoLeft = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f);
return setProperties(outtoLeft);
}
/**
* Helper method that sets some common properties
* @param animation the animation to give common properties
* @return the animation with common properties
*/
private Animation setProperties(Animation animation)
{
animation.setDuration(ANIMATION_TIME);
animation.setInterpolator(new AccelerateInterpolator());
return animation;
}
}
答案 0 :(得分:0)
您不能在普通TabHost中的视图上使用动画,因为片段已分离并附加在FragmentTabHost中。
