How to achieve right to left animation to start the activity

Question

I am working on one demo application where I want to apply animation whenever app start any activity. I wrote below code but this is for to animate the activity

Answer 1

overridePendingTransition should be called in the "target" activity. For example: Going from Activity A -> B, you would put the overridePendingTransition call in the onCreate of Activity B.

Keep in mind, if the user has disabled animation on a system level, you can't force animations to show.

EDIT:

An example would look like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    overridePendingTransition(R.anim.enter, R.anim.exit);
}

Answer 2

To apply activity transition animation on the entire application, we need to follow a few steps.

Step 1. Create four animation resources. (slide_in_left, slide_in_right, slide_out_left and slide_out_right)

Resource file: slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromXDelta="-100%p"
    android:toXDelta="0" />
</set>

Resource file: slide_in_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromXDelta="100%p"
    android:toXDelta="0" />
</set>

Resource file: slide_out_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromXDelta="0"
    android:toXDelta="-100%p" />
 </set>

Resource file: slide_out_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromXDelta="0"
    android:toXDelta="100%p" />
 </set>

Step 2. Create a custom style and use animation resources.

<style name="MyCustomActivityAnimation" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">
        @anim/slide_in_right
    </item>
    <item name="android:activityOpenExitAnimation">
        @anim/slide_out_left
    </item>
    <item name="android:activityCloseEnterAnimation">
        @anim/slide_in_left
    </item>
    <item name="android:activityCloseExitAnimation">
        @anim/slide_out_right
    </item>
</style>

Step 3. Apply the style to the theme of the application.

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    
    <item name="android:windowAnimationStyle">@style/MyCustomActivityAnimation</item>
</style>

Step 4. Apply the theme to your application in Manifest.

<application
   ....
    android:theme="@style/AppTheme"
    >
    ....
 </application>

Try this code, it's working for me

To slide from right to left

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:fillAfter="true" >
    <translate
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:fromXDelta="0%"
        android:toXDelta="-50%" >
    </translate>
</set>

To slide from left to right

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500"
    android:fromXDelta="-50%"
    android:toXDelta="0%" >
</translate>

Answer 4

Do these modifications to your animation files:

enter.xml:

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

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="500"
        android:fromXDelta="100%"
        android:fromYDelta="0%"
        android:toXDelta="0%"
        android:toYDelta="0%" />
</set>

exit.xml:

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

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="500"
        android:fromXDelta="0%"
        android:fromYDelta="0%"
        android:toXDelta="-100%"
        android:toYDelta="0%" />
</set>

You'll have your second activity sliding in from right to the left.

For a better understanding on how to play around with the fromXDelta and toXDelta values for the animations, here is a very basic illustration on the values:

This way you can easily understand why you add android:fromXDelta="0%" and android:toXDelta="-100%" for your current activity. And this is because you want it to go from 0% to the -100% position.

[EDIT]

So if you want to open ActivityB from ActivityA you do the following(let's say you have a button):

button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            startActivity(new Intent(ActivityA.this, ActivityB.class));
            overridePendingTransition(R.anim.enter, R.anim.exit);
        }
    });

Now, if you want to have the "backwards" animation of the first one, when you leave Activity B, you'll need 2 new animation files and some code in the ActivityB's onBackPressed method, like this:

First the animation files: left_to_right.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="500"
        android:fromXDelta="-100%"
        android:fromYDelta="0%"
        android:toXDelta="0%"
        android:toYDelta="0%" />
</set>

right_to_left.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="500"
        android:fromXDelta="0%"
        android:fromYDelta="0%"
        android:toXDelta="100%"
        android:toYDelta="0%" />
</set>

And in ActivityB do the following:

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.left_to_right, R.anim.right_to_left);
}

Also if you have up navigation enabled, you'll have to add the animation in this case as well:

You enable UP navigation like this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActionBar().setDisplayHomeAsUpEnabled(true);
}

And this is how you handle the animation in this case too:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    // Respond to the action bar's Up/Home button
    case android.R.id.home:
       //NavUtils.navigateUpFromSameTask(this);
       finish();
       overridePendingTransition(R.anim.left_to_right, R.anim.right_to_left);
       return true;
    }
    return super.onOptionsItemSelected(item);
}

Also be aware that even if your code is okay, your phone might have animation turned off. To turn then on do the following:

1. Open Settings and go to Developer Options
2. Make sure it is enabled (By sliding the toggle button on the top right)
3. Scroll down and under Drawing, tap these options one by one: Windows animation scale, Transition animation scale, and Animator duration scale
4. Select "Animation scale 1x"

Does this help?

Answer 5

This is the perfect code for me Slideinleft

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="100%p"
    android:toXDelta="0"
    android:duration="800"/>

Slideinright

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0"
    android:toXDelta="-100%p"
    android:duration="800"/>

In Activity

Intent intent = new Intent(getApplicationContext(),termcondionactivity.class);
Bundle bndlAnimation = ActivityOptions.makeCustomAnimation(getApplicationContext(), R.anim.slideinleft, R.anim.slideinright).toBundle();

startActivity(intent, bndlAnimation);
