现在可见性改变动画应该通过过渡API来完成，该API在支持(androidx)包中可用。只需调用TransitionManager。beginDelayedTransition方法使用Slide过渡，然后改变视图的可见性。

import androidx.transition.Slide;
import androidx.transition.Transition;
import androidx.transition.TransitionManager;

private void toggle(boolean show) {
    View redLayout = findViewById(R.id.redLayout);
    ViewGroup parent = findViewById(R.id.parent);

    Transition transition = new Slide(Gravity.BOTTOM);
    transition.setDuration(600);
    transition.addTarget(R.id.redLayout);

    TransitionManager.beginDelayedTransition(parent, transition);
    redLayout.setVisibility(show ? View.VISIBLE : View.GONE);
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/parent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="play" />

    <LinearLayout
        android:id="@+id/redLayout"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:background="#5f00"
        android:layout_alignParentBottom="true" />
</RelativeLayout>

用另一个默认和自定义转换示例检查这个答案。

这是我的解决方案。只需要获取视图的引用并调用这个方法:

public static void animateViewFromBottomToTop(final View view){

    view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

        @Override
        public void onGlobalLayout() {

            view.getViewTreeObserver().removeOnGlobalLayoutListener(this);

            final int TRANSLATION_Y = view.getHeight();
            view.setTranslationY(TRANSLATION_Y);
            view.setVisibility(View.GONE);
            view.animate()
                .translationYBy(-TRANSLATION_Y)
                .setDuration(500)
                .setStartDelay(200)
                .setListener(new AnimatorListenerAdapter() {

                    @Override
                    public void onAnimationStart(final Animator animation) {

                        view.setVisibility(View.VISIBLE);
                    }
                })
                .start();
        }
    });
}

不需要做任何其他事情=)

我有一个角落的情况，我的视图高度仍然是0所以。

import android.animation.Animator;
import android.animation.AnimatorListenerAdapter;
import android.view.View;

public final class AnimationUtils {

  public static void slideDown(final View view) {
        view.animate()
                .translationY(view.getHeight())
                .alpha(0.f)
                .setListener(new AnimatorListenerAdapter() {
                    @Override
                    public void onAnimationEnd(Animator animation) {
                        // superfluous restoration
                        view.setVisibility(View.GONE);
                        view.setAlpha(1.f);
                        view.setTranslationY(0.f);
                    }
                });
    }

    public static void slideUp(final View view) {
        view.setVisibility(View.VISIBLE);
        view.setAlpha(0.f);

        if (view.getHeight() > 0) {
            slideUpNow(view);
        } else {
            // wait till height is measured
            view.post(new Runnable() {
                @Override
                public void run() {
                    slideUpNow(view);
                }
            });
        }
    }

    private static void slideUpNow(final View view) {
        view.setTranslationY(view.getHeight());
        view.animate()
                .translationY(0)
                .alpha(1.f)
                .setListener(new AnimatorListenerAdapter() {
                    @Override
                    public void onAnimationEnd(Animator animation) {
                        view.setVisibility(View.VISIBLE);
                        view.setAlpha(1.f);
                    }
                });
    }

}

使用ObjectAnimator

private fun slideDown(view: View) {
    val height = view.height
    ObjectAnimator.ofFloat(view, View.TRANSLATION_Y, 0f, height.toFloat()).apply {
        duration = 1000
        start()
    }
}

private fun slideUp(view: View) {
    val height = view.height
    ObjectAnimator.ofFloat(view, View.TRANSLATION_Y, height.toFloat(), 0f)).apply {
        duration = 1000
        start()
    }
}

科特林

根据Suragch的回答，下面是一种使用View扩展的优雅方式:

fun View.slideUp(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, this.height.toFloat(), 0f)
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

fun View.slideDown(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, 0f, this.height.toFloat())
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

然后无论你想在哪里使用它，你只需要myview。slideup()或myview。slidedown ()

现在可见性改变动画应该通过过渡API来完成，该API在支持(androidx)包中可用。只需调用TransitionManager。beginDelayedTransition方法使用Slide过渡，然后改变视图的可见性。

import androidx.transition.Slide;
import androidx.transition.Transition;
import androidx.transition.TransitionManager;

private void toggle(boolean show) {
    View redLayout = findViewById(R.id.redLayout);
    ViewGroup parent = findViewById(R.id.parent);

    Transition transition = new Slide(Gravity.BOTTOM);
    transition.setDuration(600);
    transition.addTarget(R.id.redLayout);

    TransitionManager.beginDelayedTransition(parent, transition);
    redLayout.setVisibility(show ? View.VISIBLE : View.GONE);
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/parent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="play" />

    <LinearLayout
        android:id="@+id/redLayout"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:background="#5f00"
        android:layout_alignParentBottom="true" />
</RelativeLayout>
