this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_left_in));

this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_left_out));

if (count < 3) {

this.flipper.showNext();

count++;

}

this.flipper.setInAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_right_in));

this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this,

R.anim.push_right_out));

if (count > 1) {

this.flipper.showPrevious();

count--;

}

anim动画布局文件：

1、push_left_in.xml布局文件：

[html] view
plaincopyprint?

<span style="font-size:13px;"><?xml version="1.0" encoding="utf-8"?>

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

<translate android:fromXDelta="100%p" android:toXDelta="0"

android:duration="500" />

<alpha android:fromAlpha="0.1" android:toAlpha="1.0"

android:duration="500" />

</set></span>

[html] view
plaincopyprint?

<strong>

</strong>

2、push_left_out.xml布局文件

[html] view
plaincopyprint?

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

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

<translate android:fromXDelta="0" android:toXDelta="-100%p"

android:duration="500" />

<alpha android:fromAlpha="1.0" android:toAlpha="0.1"

android:duration="500" />

</set>

ios:UITabBarControllert添加图标

UIViewController *ctrl2 = [[UIViewController
alloc] init];
ctrl2.view.backgroundColor = [UIColor
yellowColor];
ctrl2.title =
@"#2";
UIViewController本身有个
tabBarItem变量，如果不设置，没有图标，需要图标可以这样设置：

HomeViewController *ctrl1 = [[HomeViewController
alloc] init];
UITabBarItem *item = [[UITab
写一个自定义的ViewController方便控制，分开来写是一个不错的开发思路，ios果然人性化。
