I've been trying to implement ViewFlipper and its translate animation. There are many pages I can refer to, but no matter how much I tried, I can't see outAnimation ever happen. Below is my project, and currently no translate animation is seen but IF I COMMENT OUT the vf.setOutAnimation... part, inAnimation animation suddenly starts to work. ...why?
package com.example.testview;
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.animation.AnimationUtils;
import android.widget.TextView;
import android.widget.ViewFlipper;
public class TestViewActivity extends Activity implements OnTouchListener {
private ViewFlipper vf;
private float firstTouchX;
private float leaveTouchX;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
vf = (ViewFlipper) findViewById(R.id.viewFlipper1);
vf.setOnTouchListener(this);
}
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
firstTouchX = event.getX();
break;
case MotionEvent.ACTION_UP:
leaveTouchX = event.getX();
if (this.firstTouchX - 50f > leaveTouchX) {
vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.right_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.left_out));
vf.showNext();
}
if (this.firstTouchX + 50f < leaveTouchX) {
vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.left_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.right_out));
vf.showPrevious();
}
break;
}
return true;
}
}

BIG EDIT: I just build a smaller project based on my post and it seems to work... perhaps through the process of omitting some codes that I thought unnecessary to start a discussion caused my problem.... I'm really sorry if anybody made an attempt to answer. I'll do a more survey and hope I can post breakdowns that can be of use for later references, unless mods delete this question.
BIG EDIT2: Today I tried once again, and it DIDN'T WORK, presumably because I used Android ARM 2.2 Emulator. Once I switch into ARM/Inter 2.3.3, it works.
