一.滑动界面：
第一次启动时除了启动动画外，可能还有着滑动功能介绍界面，现在记录一下这种界面的实现方式，接着上篇启动动画之后的效果附加上。
效果图：
界面：
public class SlideActivity extends Activity{
private ViewPager mViewPager;
private ImageView mPage0;
private ImageView mPage1;
private ImageView mPage2;
private ImageView mPage3;
private ImageView mPage4;
private ImageView mPage5;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.whatsnew_viewpager);
mViewPager = (ViewPager)findViewById(R.id.whatsnew_viewpager);
mViewPager.setOnPageChangeListener(new MyOnPageChangeListener());
mPage0 = (ImageView)findViewById(R.id.page0);
mPage1 = (ImageView)findViewById(R.id.page1);
mPage2 = (ImageView)findViewById(R.id.page2);
mPage3 = (ImageView)findViewById(R.id.page3);
mPage4 = (ImageView)findViewById(R.id.page4);
mPage5 = (ImageView)findViewById(R.id.page5);
//将要分页显示的View装入数组中
LayoutInflater mLi = LayoutInflater.from(this);
View view1 = mLi.inflate(R.layout.whats1, null);
View view2 = mLi.inflate(R.layout.whats2, null);
View view3 = mLi.inflate(R.layout.whats3, null);
View view4 = mLi.inflate(R.layout.whats4, null);
View view5 = mLi.inflate(R.layout.whats5, null);
View view6 = mLi.inflate(R.layout.whats6, null);
//每个页面的view数据
final ArrayList<View> views = new ArrayList<View>();
views.add(view1);
views.add(view2);
views.add(view3);
views.add(view4);
views.add(view5);
views.add(view6);
//填充ViewPager的数据适配器
PagerAdapter mPagerAdapter = new PagerAdapter() {
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}
@Override
public int getCount() {
return views.size();
}
@Override
public void destroyItem(View container, int position, Object object) {
((ViewPager)container).removeView(views.get(position));
}
@Override
public Object instantiateItem(View container, int position) {
((ViewPager)container).addView(views.get(position));
return views.get(position);
}
};
mViewPager.setAdapter(mPagerAdapter);
}
public class MyOnPageChangeListener implements OnPageChangeListener {
@Override
public void onPageSelected(int arg0) {
switch (arg0) {
case 0:
mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page));
break;
case 1:
mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page));
mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page));
break;
case 2:
mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page));

mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page));
break;
case 4:
mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page));
mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page));
break;
case 5:
mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page));
break;
}
//animation.setFillAfter(true);// True:图片停在动画结束位置
//animation.setDuration(300);
//mPageImg.startAnimation(animation);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
}
public void startbutton(View v) {
Intent intent = new Intent();
intent.setClass(SlideActivity.this,TestActivity.class);
startActivity(intent);
this.finish();
}
}布局：

每个view的布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@drawable/w1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="n旅游日记n是您外出旅游的必备应用"
android:layout_alignParentTop="true"
android:layout_marginTop="35dp"
android:textSize="22sp"
android:textColor="#fff"
/>
</RelativeLayout>如果想要实现第一次启动显示，用SharedPreferences存储下信息就行，每次启动判断下，就ok了。
