Android软件开发

 

最近在用ViewPager做引导界面，并解决了ViewPager向右滑动到最后，再向右滑动无法实现界面跳转的问题。先上效果图：

 

    

 

 

样例代码：

public class Guide extends Activity implements OnClickListener,

OnPageChangeListener ,OnTouchListener{

 

private ViewPager viewPager;

 

private ViewPagerAdapter viewPagerAdapter;

 

private List views;

 

private ImageView[] dots;

 

private int currentIndex;

 

private int lastX = 0;

 

private static final int[] pics = {R.drawable.g2, R.drawable.g3, R.drawable.g4 };

 

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.layout_guide);

views = new ArrayList();

 

LinearLayout.LayoutParams mParams = new LinearLayout.LayoutParams(

LinearLayout.LayoutParams.WRAP_CONTENT,

LinearLayout.LayoutParams.FILL_PARENT);

 

for (int i = 0; i < pics.length; i++) {

ImageView iv = new ImageView(this);

iv.setLayoutParams(mParams);

iv.setImageResource(pics[i]);

views.add(iv);

}

viewPager = (ViewPager) findViewById(R.id.viewpager);

viewPagerAdapter = new ViewPagerAdapter(views);

viewPager.setOnTouchListener(this);

viewPager.setAdapter(viewPagerAdapter);

viewPager.setOnPageChangeListener(this);

}
