i have a animation not working which should be triggered on a button click, the click checks if the image is shown and runs a animation if so, then in the else runs a different animation. problem is only the animation in the else statement is working. the if statement is still carried out if conditions are metm tested with logcat, the animation just does not happen. any help appreciated.
following being called on a click event
if (smsArea.isShown()) {
Animation backDoww = AnimationUtils.loadAnimation(getContext(),
R.anim.slide_out_right);
smsArea.startAnimation(slide_out_right);
smsArea.setVisibility(View.GONE);
}else{
Animation slide_in_right= AnimationUtils.loadAnimation(getContext(),
R.anim.slide_in_right);
smsArea.startAnimation(slide_in_right);
smsArea.setVisibility(View.VISIBLE);
}
The animation in my else statement is the only one that works, the first animation that should be triggered with the if(smsArea.isShown()) never occurs.
i'm setting the smsArea to Gone initially, i'm doing this in the onCreate not in the xml, its left as its default viable in xml. i know the error is not in my animation file as even if i use the xml file in the else which i know works the animation does not happen.
XML
<LinearLayout
android:id="#+id/smsArea"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingTop="12dp"> ..... </LinearLayout>
Animation
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<translate android:duration="300" android:fromXDelta="0%" android:toXDelta="100%"/>
<alpha android:duration="300" android:fromAlpha="1.0" android:toAlpha="0.0" />
Add animation listener:
backDoww.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
smsArea.setVisibility(View.GONE);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
in onAnimationEnd hide your view.

android:interpolator="#android:anim/accelerate_interpolator"
android:duration="2000"/>
</set>
The question is: How to fadein and fadeout image automaticaly:
android:src="#drawable/vert_loading"
Add something to MainActiviti.java?
In you java code you need to startAnimation & to repeat one after another you can listen using setAnimationListener. When onAnimationEnd is called for one you can call another startAnimation.
Following is the example for your use case:
//find imageview
ImageView image = findViewById(R.id.drawer_icon);
// get Animation objcets
Animation fadeIn = AnimationUtils.loadAnimation(this, R.anim.fadein);
Animation fadeOut = AnimationUtils.loadAnimation(this, R.anim.fadeout);
//set the initial animation
image.startAnimation(fadeIn);
//set fadeIn listener
fadeIn.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
//when fadeIn ends start the fadeout
image.startAnimation(fadeOut);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
//set fadeout listener
fadeOut.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
//when fadeOut ends start the fadeIn
image.startAnimation(fadeIn);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});

How can I make such an animation with an Android ImageView?
As simple as:
findViewById(R.id.image_view).animate()
.setStartDelay(500)
.setDuration(1000)
.scaleX(20)
.scaleY(20)
.alpha(0);
Make sure the image view is centered in your layout:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#mipmap/ic_launcher"/>
</FrameLayout>
To modify the animation further you can:
Delay the animation
Use an decelerating (or other) interpolator
Modify the scale factors
It's called Splash Screen and here is a tutorial how to achieve it - link
The difference is that you need to add after line
setContentView(R.layout.activity_splash);
Following code:
ImageView image = (ImageView) findViewById(R.id.imgLogo);
Animation animation = AnimationUtils.loadAnimation(this, R.anim.my_animation);
image.startAnimation(animation);
And add in your res/anim new file my_animation.xml contains
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<scale android:fromXScale="1.0" android:fromYScale="1.0"
android:toXScale="5.0" android:toYScale="5.0"
android:duration="3000" android:fillBefore="false"
android:pivotX="50%" android:pivotY="50%" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
android:duration="3000"/>
</set>
Agree with above answer but there is another solution: -
THis link may be useful for you just download the code and as per the link suggests
You can create in code:
// create and customize the view
SplashView splashView = new SplashView(context);
// the animation will last 0.5 seconds
splashView.setDuration(500);
// transparent hole will look white before the animation
splashView.setHoleFillColor(Color.WHITE);
// this is the Twitter blue color
splashView.setIconColor(Color.rgb(23, 169, 229));
// a Twitter icon with transparent hole in it
splashView.setIconResource(R.drawable.ic_twitter);
// remove the SplashView from MainView once animation is completed
splashView.setRemoveFromParentOnEnd(true);
or in XML:
<com.yildizkabaran.twittersplash.view.SplashView
xmlns:app="http://schemas.android.com/apk/res/com.yildizkabaran.twittersplash"
android:id="#+id/splash_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:icon="#drawable/ic_twitter"
app:iconColor="#color/twitter_blue"
app:duration="500"
app:holeFillColor="#color/white"
app:removeFromParentOnEnd="true" />
then to run the animation, simply call:
--> run the animation and listen to the animation events (listener can be left as null)
splashView.splashAndDisappear(new ISplashListener(){
#Override
public void onStart(){
}
#Override
public void onUpdate(float completionFraction){
}
#Override
public void onEnd(){
}
});`
Output will be

I am trying to to do a translate animation on an image view from the bottom to the middle of the screen. Upon finish of the animation, I want the image view to stay there. I dont want the setFillAfter(true) because I want the actual position of the imageview to be updated.
I do it currently by having 2 image view (one at the start of animation and one at the end) and I play with the setVisibility to achieve this. Is this the correct way to do things? Here is the code I used:
<ImageView
android:id="#+id/ivStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:background="#drawable/typer_step_1"
android:gravity="center"
/>
<ImageView
android:id="#+id/ivMiddle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:background="#drawable/typer_step_1"
android:gravity="center"
android:visibility="invisible"
/>
TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);
translate.setDuration(2000);
translate.setAnimationListener(new AnimationListener(){
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
ivMiddle.setVisibility(View.VISIBLE)
ivStart.setVisibility(View.INVISIBLE)
}
#Override
public void onAnimationRepeat(Animation animation) {}
});
ivStart.startAnimation(translate);
Then you must set new LayoutParams for your View which is animating. When animation finishes, in your onAnimationEnd part, set new position of your View.
TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);
translate.setDuration(2000);
translate.setAnimationListener(new AnimationListener(){
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
RelativeLayout.LayoutParams par = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
par.topMargin = mDestLoc1[1]-mSrcLoc1[1];
par.leftMargin = mDestLoc1[0]-mSrcLoc1[0];
view.setLayoutParams(par);
}
#Override
public void onAnimationRepeat(Animation animation) {}
});
view.startAnimation(translate);
Snake use my code this ll help you,
//Call this in your onCreate
private void StartAnimationsDtoU()
{
Animation anim = AnimationUtils.loadAnimation(this, R.anim.alphadtou);
anim.reset();
RelativeLayout l=(RelativeLayout) findViewById(R.id.lin_lay);
l.clearAnimation();
l.startAnimation(anim);
anim = AnimationUtils.loadAnimation(this, R.anim.translate);
anim.reset();
ImageView iv = (ImageView) findViewById(R.id.logo);
iv.setImageResource(R.drawable.earth);
iv.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
iv.clearAnimation();
iv.startAnimation(anim);
}
This is your linear layout with an image which ll move from down to middle of the screen.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/lin_lay">
<ImageView
android:id="#+id/logo"
android:layout_width="130dp"
android:layout_height="130dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#drawable/earth" />
and this ll be your xml file for translation i.e translate.xml ...
<set xmlns:android="http://schemas.android.com/apk/res/android"><translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0%"
android:toXDelta="0%"
android:fromYDelta="200%"
android:toYDelta="0%"
android:duration="4000"
android:zAdjustment="top" /></set>
and this ll be your down to up alphadtou.xml...
<?xml version="1.0" encoding="utf-8"?><alpha
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="1000" />
and also override onAttachedToWindow method like this...
#Override
public void onAttachedToWindow()
{
// TODO Auto-generated method stub
super.onAttachedToWindow();
Window window = getWindow();
window.setFormat(PixelFormat.RGBA_8888);
}
Hope this ll help you alot.
If you want the actual starting position of the image view you can get it at the time of animationStart And you can use setFillAfter(true). The setFillAfter(true) will update the position after the animation end.
If you need the new position you can use the setFilter(true). If you are not ready to use setFillAfter(true) (if you need the older position), then you have done the right thing by having two Image Views. But its better to get the position in animationStart and use setFillAfter(true).
Add this line before starting the animation
translate.setFillAfter(true);
I want to create a translate animation which will pop up a View from the top of the screen. Now I need to put my view above the screen , so that it will be invisible . The root of all Views is a vertical LinearLayout . This is how I inflate the RelativeLayout (which is going to be animated) into my LinearLayout.
final LinearLayout root = (LinearLayout) findViewById (R.id.mainLayout);
final RelativeLayout container = (RelativeLayout)
LayoutInflater.from(getBaseContext()).
inflate(R.layout.animated_layout ,
root , false );
root.addView(container);
and this is the Relativelayout xml .
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#drawable/list_item_back1" >
<TextView
android:textSize="25sp"
android:layout_width = "match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
Ass you said, become your view invisible. Then, create an XML translate animation:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<translate
android:fromYDelta="100%"
android:toYDelta="0%"
android:duration="1000" />
</set>
In your java code do something like this:
Animation translateAnimation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.translate_animation);
translateAnimation.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
yourAnimatedView.setvisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
yourAnimatedView.startAnimation(translateAnimation);
});
As by object, I would reproduce fade effect between two layout.
Now I've this situation:
LinearLayout l;
LinearLayout l2;
To switch between them I've used
l.setVisibility(View.GONE);
l2.setVisibility(View.VISIBLE);
I want add fade effect between this transiction, how I can do it?
Here is a working solution to cross fade between 2 layouts:
public class CrossFadeActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.crossfade);
final View l1 = findViewById(R.id.l1);
final View l2 = findViewById(R.id.l2);
final Animation fadeOut = AnimationUtils.loadAnimation(CrossFadeActivity.this, R.anim.fade_out);
final Animation fadeIn = AnimationUtils.loadAnimation(CrossFadeActivity.this, R.anim.fade_in);
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
fadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
l1.setVisibility(View.GONE);
}
});
l1.startAnimation(fadeOut);
l2.setVisibility(View.VISIBLE);
l2.startAnimation(fadeIn);
}
});
findViewById(R.id.button2).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
fadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
l2.setVisibility(View.GONE);
}
});
l2.startAnimation(fadeOut);
l1.setVisibility(View.VISIBLE);
l1.startAnimation(fadeIn);
}
});
}
}
crossfade.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/l1"
android:layout_width="fill_parent"
android:layout_height="300dip"
android:orientation="vertical"
android:background="#drawable/someimage"
>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
<RelativeLayout
android:id="#+id/l2"
android:layout_width="fill_parent"
android:layout_height="300dip"
android:orientation="vertical"
android:background="#drawable/someimage2"
android:visibility="gone"
>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_centerInParent="true"
/>
</RelativeLayout>
</RelativeLayout>
Where l1 and l2 are 2 random example layouts. The trick is to put them in XML such that they overlap each other (e.g. in a RelativeLayout) with visible / gone, add listeners to the animations to toggle the visibility on finish, and set the view which has to fade in to visible before the animation starts, otherwise the animation will not be visible.
I put the buttons with the listeners to toggle the animation in the layouts itself, because I need to implement it that way but the click listener can be of course somewhere else (if it's only one it should be used in combination with some flag or check to know how to toggle).
These are the animation files. They have to be stored in folder res/anim:
fade_in.xml
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fillAfter="true"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
fade_out.xml
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fillAfter="true"
android:fromAlpha="1.0"
android:toAlpha="0" />
UPDATE:
Instead of using R.anim.fade_in, you can use the default fade_in from Android API (android.R.fade_in):
final Animation fadeIn = AnimationUtils.loadAnimation(CrossFadeActivity.this, android.R.anim.fade_in);
Using android.R.anim.fade_in, you will not need to create the file res/anim/fade_in.xml.
Android has a package with some useful animations on android.R.anim: http://developer.android.com/reference/android/R.anim.html
Using R.anim.fade_out & .R.anim.fade_in you can create an animation which does this. I don't know much about this myself but heres a tutorial regarding animations in android: Animation Tutorial
P.S. This tutorial is not mine thus credit does not go out to me.
Edit:
AnimationSet set = new AnimationSet(true);
Animation animation = new AlphaAnimation(0.0f, 1.0f);
animation.setDuration(50);
set.addAnimation(animation);
animation = new TranslateAnimation(
Animation.RELATIVE_TO_SELF, 0.0f,Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, -1.0f,Animation.RELATIVE_TO_SELF, 0.0f
);
animation.setDuration(100);
set.addAnimation(animation);
LayoutAnimationController controller = new LayoutAnimationController(set, 0.5f);
l.setLayoutAnimation(controller);
Fade out Animation
public static Animation runFadeOutAnimationOn(Activity ctx, View target) {
Animation animation = AnimationUtils.loadAnimation(ctx,android.R.anim.fade_out);
target.startAnimation(animation);
return animation;
}
I'm guessing you can try something like this, I copy pasted the animation from the tutorial I don't know what it does exactly as I have no experience with Android development. Another example could be Example 2
Since android 3.0 you can use
android:animateLayoutChanges="true"
in a layout in xml and any changes to this specific layouts content at run time will be animated. For example, in your case, you will need to set this attribute for the parent for the parent layout of l and l2 e.g
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="me.kalem.android.RegistrationActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:animateLayoutChanges="true"
android:padding="20dp">
<LinearLayout
android:id="#+id/l1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="visible">
........
</LinearLayout>
<LinearLayout
android:id="#+id/l2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone">
........
</LinearLayout>
</LinearLayout>
Now hiding l1 and showing l2 at runtime will be animated.
