Show and hide a View with a slide up/down animatio

2020-01-22 13:38发布

I have a LinearLayout that I want to show or hide with an Animation that pushes the layout upwards or downwards whenever I change its visibility.

I've seen a few samples out there but none of them suit my needs.

I have created two xml files for the animations but I do not know how to start them when I change the visibility of a LinearLayout.

I was having troubles understanding an applying the accepted answer. I needed a little more context. Now that I have figured it out, here is a full example:

enter image description here

MainActivity.java

public class MainActivity extends AppCompatActivity {

    Button myButton;
    View myView;
    boolean isUp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        myView = findViewById(R.id.my_view);
        myButton = findViewById(R.id.my_button);

        // initialize as invisible (could also do in xml)
        myView.setVisibility(View.INVISIBLE);
        myButton.setText("Slide up");
        isUp = false;
    }

    // slide the view from below itself to the current position
    public void slideUp(View view){
        view.setVisibility(View.VISIBLE);
        TranslateAnimation animate = new TranslateAnimation(
                0,                 // fromXDelta
                0,                 // toXDelta
                view.getHeight(),  // fromYDelta
                0);                // toYDelta
        animate.setDuration(500);
        animate.setFillAfter(true);
        view.startAnimation(animate);
    }

    // slide the view from its current position to below itself
    public void slideDown(View view){
        TranslateAnimation animate = new TranslateAnimation(
                0,                 // fromXDelta
                0,                 // toXDelta
                0,                 // fromYDelta
                view.getHeight()); // toYDelta
        animate.setDuration(500);
        animate.setFillAfter(true);
        view.startAnimation(animate);
    }

    public void onSlideViewButtonClick(View view) {
        if (isUp) {
            slideDown(myView);
            myButton.setText("Slide up");
        } else {
            slideUp(myView);
            myButton.setText("Slide down");
        }
        isUp = !isUp;
    }
}

activity_mail.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:layout_marginTop="100dp"
        android:onClick="onSlideViewButtonClick"
        android:layout_width="150dp"
        android:layout_height="wrap_content"/>

    <LinearLayout
        android:id="@+id/my_view"

        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="200dp">

    </LinearLayout>

</RelativeLayout>

Notes

  • Thanks to this article for pointing me in the right direction. It was more helpful than the other answers on this page.
  • If you want to start with the view on screen, then don't initialize it as INVISIBLE.
  • Since we are animating it completely off screen, there is no need to set it back to INVISIBLE. If you are not animating completely off screen, though, then you can add an alpha animation and set the visibility with an AnimatorListenerAdapter.

if (filter_section.getVisibility() == View.GONE) {
    filter_section.animate()
            .translationY(filter_section.getHeight()).alpha(1.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationStart(Animator animation) {
                    super.onAnimationStart(animation);
                    filter_section.setVisibility(View.VISIBLE);

you can slide up and down any view or layout by using bellow code in android app

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));
                }

Now visibility change animations should be done via Transition API which available in support (androidx) package. Just call TransitionManager.beginDelayedTransition method with Slide transition then change visibility of the view.

enter image description here

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

private void toggle() {
    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>

Here is my solution. Just get a reference to your view and call this method:

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();
        }
    });
}

No need to do anything else =)

You can used the simple three lines of code to show the animation...

//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)

            }
