ImageSwitcher，TextSwitcher实现图片，文字切换

public class MyImageSwitch extends Activity implements ViewFactory,OnTouchListener{

is.setOnTouchListener(this);
is.setFactory(this);

}

@Override
public View makeView() {
ImageView iv=new ImageView(this);
iv.setImageResource(images[0]);
return iv;
}

float start=0.0f;
float end=0.0f;
//实现触屏
@Override

int action = event.getAction();//获取当前的动作
if(action==MotionEvent.ACTION_DOWN){ //当点下去的时候
start = event.getX();
return true;
}
if(action==MotionEvent.ACTION_UP){//获取当你点击完后的x轴
end = event.getX();
return true;
}
if(start-end>100){ //像左
index=index+1<images.length ? ++index : 0;

is.setInAnimation(this,android.R.anim.fade_in);//设置进的动画
is.setOutAnimation(this,android.R.anim.fade_out);//设置出的动画
}else if(end-start>20){
index=index-1>=0 ? --index:images.length-1;
