I want to continuously show different text on text view which animates from left to right, waits on the center of the screen for 3 sec and animates outside of the screen and replaced by a new text which animates from left to right
I have included a textview inside a viewflipper.

MainActivity Code
public class Main6Activity extends AppCompatActivity {
private ViewFlipper mViewFlipper;
private int count = 0;
private TextView textView;
private ConstraintLayout rootContainer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main6);
mViewFlipper = findViewById(R.id.view_flipper);
textView = findViewById(R.id.tv);
rootContainer = findViewById(R.id.rl__inc_pre_sing__tm_container);
mViewFlipper.setAutoStart(true);
mViewFlipper.startFlipping();
mViewFlipper.setInAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_in_left));
mViewFlipper.setOutAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_out_right));
Resources resources = getApplicationContext().getResources();
final String[] textString = resources.getStringArray(R.array.teacher_messages);
new Thread() {
@Override
public void run() {
super.run();
try {
while (!isInterrupted()) {
Thread.sleep(3000);
runOnUiThread(() -> updateText(textString));
}
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
public void updateText(String[] strings) {
if (count >= strings.length) {
count = 0;
}
textView.setText(strings[count]);
count++;
}
}
I guess the outanimation does not work as the textview length changes and I want to animate the constraint layout according to the textview height. Not sure if this is the right reason.
The outAnimation of the view flipper does not work.
That's not how ViewFlipper works . the View flipper will only animate the view added to it .
Here's an example :
<ViewFlipper
android:id="@+id/viewFlipper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/loading"
android:autoStart="true"
android:flipInterval="5000"
android:inAnimation="@android:anim/slide_in_left"
android:outAnimation="@android:anim/slide_out_right">
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/text1"
android:textColor="@color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/text3"
android:textColor="@color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/tex2"
android:textColor="@color/white"
android:textSize="18sp" />
</ViewFlipper>
If that does not suit your needs . you can take a look at this solution. (Animating text changes in a TextView)
