替换片段时如何应用淡入/淡出动画 [英] How to apply a fade-in/fade-out animation when replacing a fragment

问题描述

我正在用另一个片段替换一个片段.我希望第一个片段以淡出效果消失，第二个片段以淡入效果出现.怎么做?

I am replacing a fragment with another fragment. I want the first fragment to disappear with a fade-out effect and second fragment to appear with fade-in effect. How is this done?

推荐答案

除了@MD代码

FragmentManager manager = getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();

ft.setCustomAnimations(R.anim.fade_in,
                R.anim.fade_out);
ft.replace(R.id.realtabcontent, fragment);
ft.commit();

然后当您弹出片段时，请应用以下动画:

and When you Pop Fragment then apply animation like:

FragmentManager manager = getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
ft.setCustomAnimations(R.anim.fade_out, R.anim.fade_in);

ft.replace(R.id.realtabcontent, fragment);      
ft.commit();

和XML用于fadingIn

and XML for fadeIn

<set xmlns:android="http://schemas.android.com/apk/res/android">
       <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

和XML用于淡出

<set xmlns:android="http://schemas.android.com/apk/res/android">
       <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>
