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()
    }
}

Suragch用科特林语回答。这对我很管用。

class MainActivity : AppCompatActivity() {

var isUp: Boolean = false

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    var myView: View = findViewById(R.id.my_view)
    var myButton: Button = findViewById(R.id.my_button)

    //Initialize as invisible
    myView.visibility = View.INVISIBLE
    myButton.setText("Slide up")

    isUp = false

}


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)
}

fun onSlideViewButtonClick(view: View){
    if(isUp){
        my_view.slideDown()
        my_button.setText("Slide Up")

    }
    else{
        my_view.slideUp()
        my_button.setText("Slide Down")
    }
    isUp = !isUp
}

}

从ashakirov的回答为Kotlin用户

 val transition: Transition = Slide(Gravity.BOTTOM)
                transition.duration = 600
                transition.addTarget(you_parent_layout_id)
TransitionManager.beginDelayedTransition(rootLayoutId, transition)
                yourViewIdToHide.visibility = if (yourViewIdToHide.isShown) View.GONE else View.VISIBLE

随着Android 3.0 (Honeycomb)引入的新动画API，创建这样的动画非常简单。

将视图向下滑动一段距离:

view.animate().translationY(distance);

你可以稍后将视图滑回原来的位置，如下所示:

view.animate().translationY(0);

您还可以轻松地组合多个动画。下面的动画会将一个视图按高度向下滑动，同时淡入:

// Prepare the View for the animation
view.setVisibility(View.VISIBLE);
view.setAlpha(0.0f);

// Start the animation
view.animate()
    .translationY(view.getHeight())
    .alpha(1.0f)
    .setListener(null);

然后，您可以将视图淡出，并将其滑回原始位置。我们还设置了一个AnimatorListener，这样我们可以在动画完成后将视图的可见性设置为GONE:

view.animate()
    .translationY(0)
    .alpha(0.0f)
    .setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            view.setVisibility(View.GONE);
        }
    });

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 ()

当LinearLayout的可见性改变时，你可以通过创建LinearLayout的一个新的子类并覆盖setVisibility()来启动动画来启动正确的动画。考虑一下这样的事情:

public class SimpleViewAnimator extends LinearLayout
{
    private Animation inAnimation;
    private Animation outAnimation;

    public SimpleViewAnimator(Context context)
    {
        super(context);
    }

    public void setInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void setOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }

    @Override
    public void setVisibility(int visibility)
    {
        if (getVisibility() != visibility)
        {
            if (visibility == VISIBLE)
            {
                if (inAnimation != null) startAnimation(inAnimation);
            }
            else if ((visibility == INVISIBLE) || (visibility == GONE))
            {
                if (outAnimation != null) startAnimation(outAnimation);
            }
        }

        super.setVisibility(visibility);
    }
}
