How to achieve right to left animation to start the activity
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);
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);
}
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:
- Open Settings and go to Developer Options
- Make sure it is enabled (By sliding the toggle button on the top right)
- Scroll down and under Drawing, tap these options one by one: Windows animation scale, Transition animation scale, and Animator duration scale
- Select "Animation scale 1x"
Does this help?
