如何在Android中使用平滑的动画翻译视图

Question

I have written a peace of code that perform animation. for that i have written a animation file in anim folder

my animone.xml file
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/linear_interpolator"
     android:fillAfter="true">
     <translate
         android:fromYDelta="0%p"
         android:toYDelta="-5%p"
         android:duration="1500"/></set>

and here i apply the animation on the view that is a LinearLayout

Animation animate= AnimationUtils.loadAnimation(context,R.anim.animone);
            subProfile.setVisibility(View.VISIBLE);//subProfile is a linear layout
            subProfile.startAnimation(animate);

so when i run this code . it will suddenly change the position of view without smooth sliding after specified duration. i want to make it smooth. please help.

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"

-----------java file in which i apply the animation on click event---------

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.my_pofile:
            animate= AnimationUtils.loadAnimation(ctx,R.anim.animone);
            subProfile.setVisibility(View.VISIBLE);
            subProfile.startAnimation(animate);
    break;
    //other cases
}}

Answer 1

Try this:

  <?xml version="1.0" encoding="utf-8"?>

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromYDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toYDelta="-100%" />

Answer 2

Try to

reduce the resolution or size of all images inside that layout

It will fix the smooth problem.

I also experience this problem and searched on internet but nothing found, then I felt that everything was slow on my layout, then I reduced the resolution and size of all images including backgrounds and you what everything starts working so smooth.

This will fix 100%, It doesn't matter what you use for animation such as AnimationUtils or ObjectAnimator. If it doesn't work smoothly just reduce the resolution of images you are using.

Thanks
