android应用引导页面的设计

引导页面主要用了就是viewpager滑动，本设计中真对每一个页面都放了一个button（都得听设计的），点击按钮进入主页面，主页面就象征了一个界面就不放代码了。本文主要完成导航页面。小圆点直接嵌入图片了。主要进行对viewpager适配的解释，注意button是每个view中的button，需要view.一下。button的设计用了shape 可以参考http://www.cnblogs.com/tinyphp/p/3829895.html每张图片占一个布局。跳转的页面别忘了在manifest里面添加。

public class MainActivity extends ActionBarActivity implements OnClickListener{private ViewPager viewPager;private View view1,view2,view3,view4;private List<View> viewlist;private Button bt_1,bt_2,bt_3,bt_4;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);viewPager = (ViewPager) findViewById(R.id.viewpager);LayoutInflater inflater = getLayoutInflater();view1 = inflater.inflate(R.layout.layout1, null);view2 = inflater.inflate(R.layout.layout2, null);view3 = inflater.inflate(R.layout.layout3, null);view4 = inflater.inflate(R.layout.layout4, null);viewlist = new ArrayList<View>();viewlist.add(view1);viewlist.add(view2);viewlist.add(view3);viewlist.add(view4);bt_1 = (Button) view1.findViewById(R.id.bt_1);bt_2 = (Button) view2.findViewById(R.id.bt_2);bt_3 = (Button) view3.findViewById(R.id.bt_3);bt_4 = (Button) view4.findViewById(R.id.bt_4);bt_1.setOnClickListener(this);bt_2.setOnClickListener(this);bt_3.setOnClickListener(this);bt_4.setOnClickListener(this);//适配PagerAdapter adapter = new PagerAdapter() {@Overridepublic boolean isViewFromObject(View arg0, Object arg1) {// TODO Auto-generated method stub//根据传来的key，找到view,判断与传来的参数View arg0是不是同一个视图return arg0 == viewlist.get((int)Integer.parseInt(arg1.toString()));}//getCount():返回要滑动的VIew的个数@Overridepublic int getCount() {// TODO Auto-generated method stubreturn viewlist.size();}//destroyItem（）：从当前container中删除指定位置（position）的View;@Overridepublic void destroyItem(ViewGroup container, int position,Object object) {// TODO Auto-generated method stubcontainer.removeView(viewlist.get(position));}//instantiateItem()：做了两件事，第一：将当前视图添加到container中，第二：返回当前View@Overridepublic Object instantiateItem(ViewGroup container, int position) {// TODO Auto-generated method stubcontainer.addView(viewlist.get(position));//把当前新增视图的位置（position）作为Key传过去return position;}};viewPager.setAdapter(adapter);}@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()) {case R.id.bt_1:Intent intent = new Intent(MainActivity.this,Entry.class);MainActivity.this.startActivity(intent);finish();break;case R.id.bt_2:Intent intent2 = new Intent(MainActivity.this,Entry.class);MainActivity.this.startActivity(intent2);finish();break;case R.id.bt_3:Intent intent3 = new Intent(MainActivity.this,Entry.class);MainActivity.this.startActivity(intent3);finish();break;case R.id.bt_4:Intent intent4 = new Intent(MainActivity.this,Entry.class);MainActivity.this.startActivity(intent4);finish();break;default:break;}}
