Android fade in , fade out animation issue - android

I'm trying to customize the animation between two activities by fading out the splashscreen and fading in the main activity.
I trying two solutions, one with fade_in.xml and fade_out.xml where controlling alphas (0-1 , 1-0) and calling everything with overridePendingTransaction(fade_in, fade_out) and one with fade and hold like ni api demo (api/app/animation/fade);
The main problem is that the splashscreen (first animation ) is losing its alpha while sliding to the right as well and the second activity is appearing as wanted.
How is possible to lock the splashscreen to its original position and just making it fading out?
fade
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="#android:integer/config_longAnimTime" />
hold
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromXDelta="0" android:toXDelta="0"
android:duration="#android:integer/config_longAnimTime" />
overridePendingTransition(R.anim.fade, R.anim.hold);

You can use the callback for .fadeOut().

Stop image-view by using animation on particular screen position

This is what I have done now I want to stop this animation on a particular screen position and I know during the animation it could not stop so please provide another way where I could implement this functionality in my app.
<?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:toYDelta="100%p"
android:duration="6000"
android:fillEnabled="false"
android:startOffset="5000"
android:fillAfter="false"/>
</set>
You have to give android:fromXDelta=""
android:toXDelta=""
android:fromYDelta=""
android:toYDelta=""

Opening a new activity: animation starts but activity is showed before the animation

I do:
startActivityForResult(i, NEW_ACTIVITY);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
The new Activity starts, but it is showed immediately... And only in a second time, it disappear and then fades in as requested. In other words, when I execute the above code, the new animation
flashes one time
disappears
fades in
I don't want the step 1.
PS:
fade in:
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="750" />
fade out:
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="750" />
*Edit*
I realize that it happens ONLY when in the activity's onCreate() there is a ProgressDialog.show() command! If I show a ProgressDialog in te onCreate, this make animation to be wrong! Any Idea?
Maybe You could use an AnimationListener and in onAnimationEnd(), start Your activity.

Animate the activity entry

I need to start an activity in an animated way..can anyone help me?
Creating an intent and starting an activity in normal way will show new activity.I need to start it from one side,say left side..how to animate it near creating intent..
Use the following:
this.overridePendingTransition(R.anim.slidein_left, R.anim.slideout_right);
Where R.anim.* are Animation XML files in your /res/anim/ folder.
The following is an example of my slidein_left:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="-100%"
android:toXDelta="0%" />
</set>
And slideout_right:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="0%"
android:toXDelta="100%" />
</set>
What this will do is slide both activities to the left, making the new activity slide in from the left, pushing the old activity out to the right.
Also, as stated by #njzk2, please attempt to make an effort yourself before asking questions, and provide us with things that you may have already tried.

Android - Animation offset - How to prevent the view from being drawn while the offset has not yet passed?

I am trying to start an animation AFTER 1 second. I have used the attribute "android:startOffset" in my XML file, but it does not work completely the way I expected. I was expecting the view to NOT EVEN BE DRAW in its initial position (that is, the position set in the attributes "fromXDelta" and "fromYDelta") before the offset I set has passed. Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="sequentially"
android:shareInterpolator="false" >
<translate
android:duration="2000"
android:startOffset="1000"
android:fromXDelta="-70%p"
android:fromYDelta="0%p"
android:interpolator="#android:anim/linear_interpolator"
android:toXDelta="+0%p"
android:toYDelta="0%p" />
</set>
If I try to move my view using the above animation, the view is drawn IMMEDIATELY at the position -70% of the screen. Then the one second passes and then, as expected, the animation kicks in and starts to move the view. However, I DO NOT want the view to be drawn at all before that 1 second!. How can I achieve this?
Thank you in advance.
UPDATE
I am calling the above XML just after a startActivity call (the *R.anim.animation_coming_in* below), like this:
startActivity(new Intent(this, ThankYouActivity.class));
overridePendingTransition(R.anim.animation_coming_in, R.anim.animation_coming_out);
You could try using a pair of alpha animations with very short duration so that the view is hidden until it's needed. Something like this:
<set ...>
<alpha
android:fromAlpha="0.0"
android:toAlpha="0.0"
android:duration="1"
android:startOffset="0" />
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="1"
android:startOffset="1000" />
<translate
...
/>
</set>
Alternatively, you could implement this set of animations in code. Doing so would enable you to use a Handler to start the animation after a delay so that the view is hidden until the animation starts.

Android transition not working on phone

I created some transitions between activities that are working fine in the emulator, but nothing of them can be seen on the phone (neither fade in-out nor slide). The new activity simply appears like I have not implemented any transitions. Why is that?
fadein.xml
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" />
fadeout.xml
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="1000" />
And i set in the appropriate activity
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
Make sure that animations are enabled on device. For this go to Settings->Display->Animations and select "All Animations".
Enable the transition animation
Settings -> Developer Options -> Transition Animation Scale -> 1x
Go to Settigs then developer options and check for the options that are related to animation and assure that each one of animation option is switched on
