Animation between Activities, of which one is singleTask

Question

I'm developing a chat app and am having trouble with figuring out how to get the transition between two activities to animate correctly. I have googled this for a while now and have also searched SO for it, but sorry in advance if this question has already been answered.

I have a

ChatMainActivity

, which holds a Fragment containing a list of chats and a

ChatContentFragmentActivity

, which holds a Fragment containing the chat messages. As seen below I have declared the ChatMainActivity as

launchMode="singleTask"

in my AndroidManifest.xml.

  <activity

        android:name=".ui.activities.ChatMainActivity"

        android:launchMode="singleTask"

        android:theme="@style/AppTheme"

        android:windowSoftInputMode="adjustResize" />

  <activity

        android:name=".ui.activities.ChatContentFragmentActivity"

        android:parentActivityName=".ui.activities.ChatMainActivity"

        android:theme="@style/AppTheme"

        android:windowSoftInputMode="adjustResize" />

These are my animation .xmls:

chat_content_activity_enter_animation.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate

        android:duration="@integer/activity_animation_duration"

        android:fromXDelta="100%"

        android:interpolator="@android:anim/decelerate_interpolator"

        android:toXDelta="0" />

</set>

chat_content_activity_exit_animation.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate

        android:duration="@integer/activity_animation_duration"

        android:fromXDelta="0"

        android:interpolator="@android:anim/decelerate_interpolator"

        android:toXDelta="100%" />

</set>

chat_list_activity_enter_animation.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate

        android:duration="@integer/activity_animation_duration"

        android:fromXDelta="-100%"

        android:interpolator="@android:anim/decelerate_interpolator"

        android:toXDelta="0" />

</set>

chat_list_activity_exit_animation.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate

        android:duration="@integer/activity_animation_duration"

        android:fromXDelta="0"

        android:interpolator="@android:anim/decelerate_interpolator"

        android:toXDelta="-100%" />

</set>

And here is how I use them:

In the

Adapter

of the

RecyclerView

containing the chats in

ChatMainActivity

Intent intent = new Intent(context, ChatContentFragmentActivity.class);

context.startActivity(intent);

activity.overridePendingTransition(R.anim.chat_content_activity_enter_animation, R.anim.chat_list_activity_exit_animation);

ChatContentFragmentActivity

@Override

public void finish() {

    super.finish();

    overridePendingTransition(R.anim.chat_content_activity_exit_animation, R.anim.chat_list_activity_enter_animation);

}

My Problem now is that the enter and exit animations of the

ChatContentFragmentActivity

are shown, but the

ChatMainActivity

does nothing.

There was a SO question that I can't seem to find now, that suggested, that singleTask was a problem here, but I remember the solution suggest in that question not helping me.

Does anyone know how I can get the exit and enter animation of my

ChatMainActivity

to play?

Edit: This is how it looks at the moment:

use this .

pull_right.xml

 <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="100%"
    android:toXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
    />

push_left.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toXDelta="-100%" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha
        android:duration="300"
        android:fromAlpha="1.0"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toAlpha="0.0" />
</set>

use in the Adapter this........

Intent intent = new Intent(context, ChatContentFragmentActivity.class);
context.startActivity(intent);
activity.overridePendingTransition(R.anim.pull_right, R.anim.push_left);

use this in the ChatContentFragmentActivity Class onBackPressed() method.......

@Override
    public void onBackPressed() {
        super.onBackPressed();
        overridePendingTransition( R.anim.fade_out,0);
    }

and for keyboard just add these line in your xml file in EditText Tag of ChatContentFragmentActivity ....

android:focusable="true"
android:focusableInTouchMode="true"

enjoy coding ..........
