支持片段推送弹出动画

Question

我在我的应用程序中通过 AppCompatActivity 使用 v4 支持片段。

    loginUserFragment = new FragmentLoginUser();
    mFragmentTransaction = CommonUtils.getFragmentLRTransaction(this);
    mFragmentTransaction.add(R.id.fragmentContainer, loginUserFragment, loginUserFragment.getClass().getName());
    mFragmentTransaction.commit();

片段从左到右事务：

public static FragmentTransaction getFragmentLRTransaction(FragmentActivity fa) {
    FragmentTransaction ft = fa.getSupportFragmentManager().beginTransaction();
    ft.setCustomAnimations(anim.animated_activity_slide_left_in, anim.animated_activity_slide_right_out, anim.animated_activity_slide_right_in, anim.animated_activity_slide_left_out);
    return ft;
}

animated_activity_slide_left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXDelta="-100%p"
android:toXDelta="0%p" 
android:duration="250"/>

animated_activity_slide_right_out.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXDelta="0%p"
android:toXDelta="100%p" 
android:duration="250"/>

animated_activity_slide_right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXDelta="100%p"
android:toXDelta="0%p" 
android:duration="250"/>

animated_activity_slide_left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXDelta="0%p"
android:toXDelta="-100%p" 
android:duration="250"/>

Push 和 Pop Animation 都不起作用 :(

Answer 1

将mFragmentTransaction.add(...); 替换为mFragmentTransaction.replace(...);

Answer 2

试试这个，

您的推送和弹出片段如下所示，

public void pushFragments(String tag, Fragment fragment,
            boolean shouldAnimate, boolean shouldAdd) {
        try {
            if (shouldAdd)
                mStacks.get(tag).push(fragment);
            FragmentManager manager = getSupportFragmentManager();
            FragmentTransaction ft = manager.beginTransaction();
            if (shouldAnimate)
                ft.setCustomAnimations(R.anim.from_fade_in,
                        R.anim.from_fade_out);
            ft.replace(R.id.realTabContent, fragment);
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void pushFragments(String tag, Fragment fragment, Bundle args,
            boolean shouldAnimate, boolean shouldAdd) {
        try {
            if (shouldAdd)
                mStacks.get(tag).push(fragment).setArguments(args);
            FragmentManager manager = getSupportFragmentManager();
            FragmentTransaction ft = manager.beginTransaction();
            if (shouldAnimate)
                ft.setCustomAnimations(R.anim.from_fade_in,
                        R.anim.from_fade_out);
            ft.replace(R.id.realTabContent, fragment);
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void popFragments() {
        try {
            Fragment fragment = mStacks
                    .get(GlobalFields.mCurrentTab)
                    .elementAt(mStacks.get(GlobalFields.mCurrentTab).size() - 2);

            /* pop current fragment from stack.. */
            mStacks.get(GlobalFields.mCurrentTab).pop();

            /*
             * We have the target fragment in hand.. Just show it.. Show a
             * standard navigation animation
             */
            FragmentManager manager = getSupportFragmentManager();
            FragmentTransaction ft = manager.beginTransaction();
            ft.setCustomAnimations(R.anim.to_fade_in, R.anim.to_fade_out);
            ft.replace(R.id.realTabContent, fragment);
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Answer 3

您可以使用 translate 为活动设置动画，但不能使用 translate 为片段设置动画。对于片段，您应该使用对象动画师。

更新：

但正如@user3400729 所指出的，支持片段管理器不能使用对象动画器进行过渡，但可以使用翻译来应用此动画。

在这种情况下，我尝试了您的问题，发现动画效果很好，我所做的只是增加动画的持续时间，以便用户可以查看此动画。
