你可以使用简单的三行代码来显示动画…

//getting the hiding view by animation

 mbinding.butn.setOnClickListener {

                val SlideOutLeft = AnimationUtils.loadAnimation(this, R.anim.slide_out_left)
                simplelayout.visibility = View.INVISIBLE
                simplelayout.startAnimation(SlideOutLeft)


                val SlideInRight = AnimationUtils.loadAnimation(applicationContext, R.anim.slide_in_right)
                animation1.visibility = View.VISIBLE
                animation1.startAnimation(SlideInRight)

            }
            //again unhide the view animation
            mbinding.buttn.setOnClickListener {


               val SlideInLeft=AnimationUtils.loadAnimation(this,R.anim.slide_in_left)
                //set the layout
               simplelayout.visibility=View.VISIBLE
               simplelayout.startAnimation(SlideInLeft)

               val SlideOutRight=AnimationUtils.loadAnimation(this,R.anim.slide_out_right)
               animation1.visibility=View.INVISIBLE
               animation1.startAnimation(SlideOutRight)

            }

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);
    }
}

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
}

}

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);
                    }
                });
    }

}

你可以上下滑动任何视图或布局使用咆哮的代码在安卓应用程序

boolean isClicked = false;
LinearLayout mLayoutTab = (LinearLayout) findViewById(R.id.linearlayout);

if(isClicked) {
    isClicked = false;
    mLayoutTab.animate()
        .translationYBy(120)
        .translationY(0)     
        .setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
} else {
    isClicked = true;
    mLayoutTab.animate()
         .translationYBy(0)
         .translationY(120)
         .setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}

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()
    }
}
