a. 活动过程中的蒸 fragment碎片
原标题:swap fragment in an activity via animation

我想通过估计在一项活动中分两部分。 附录 A是rag缩的A,留在屏幕上,而B页是碎块,即屏幕右侧。 现在想要的是,当我点击一顿在一页上。 之后,页面A会向屏幕右侧移动,进行一些过渡性估算。

我尝试用以下文字取代立场:

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container, new FragB());
fragmentTransaction.commit();

看一下某些cl子。

最佳回答

旧的追求和你可能已经表明了这一点,但今后可以参考:

在你通过代号替换碎块时,你用来确定一种习俗估计:

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();

ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
ft.replace(R.id.fragment_container, newFragment, "fragment");
// Start the animated transition.
ft.commit();

这里是幻灯片的事例:

<?xml version="1.0" encoding="utf-8"?>
<set>
  <translate xmlns:android="http://schemas.android.com/apk/res/android"
   android:fromXDelta="-100%"
   android:toXDelta="0"
   android:interpolator="@android:anim/decelerate_interpolator"
   android:duration="500"/>
</set>

请注意,如果你使用相容图书馆,这是估算值。 相反,如果你使用SDK,并且得到当地支持,支持FigmentManager,那么你就会想像:

<?xml version="1.0" encoding="utf-8"?>
<set>
  <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:propertyName="x" 
    android:valueType="floatType"
    android:valueFrom="-1280"
    android:valueTo="0" 
    android:duration="500"/>
</set>

这是因为相容的图书馆不支持新物体的类型,而只是执行旧的估算框架。
