ViewPager,它是google SDk中自帶的一個附加包的一個類, 可使視圖滑動。php
步驟:html
一、引入android-support-v4.jar包,在主佈局里加入android
<android.support.v4.view.ViewPager android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="wrap_content" > </android.support.v4.view.ViewPager>
二、加載切換內容數組
三、ViewPager加載適配器PagerAdapteride
public class MainActivity extends Activity { private ViewPager viewPager; private ArrayList<View> pageview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //設置無標題欄 requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.main); viewPager = (ViewPager) findViewById(R.id.viewPager); //查找佈局文件用LayoutInflater.inflate LayoutInflater inflater =getLayoutInflater(); View view1 = inflater.inflate(R.layout.item01, null); View view2 = inflater.inflate(R.layout.item02, null); View view3 = inflater.inflate(R.layout.item03, null); //將view裝入數組 pageview =new ArrayList<View>(); pageview.add(view1); pageview.add(view2); pageview.add(view3); //數據適配器 PagerAdapter mPagerAdapter = new PagerAdapter(){ @Override //獲取當前窗體界面數 public int getCount() { // TODO Auto-generated method stub return pageview.size(); } @Override //斷是否由對象生成界面 public boolean isViewFromObject(View arg0, Object arg1) { // TODO Auto-generated method stub return arg0==arg1; } //是從ViewGroup中移出當前View public void destroyItem(View arg0, int arg1, Object arg2) { ((ViewPager) arg0).removeView(pageview.get(arg1)); } //返回一個對象,這個對象代表了PagerAdapter適配器選擇哪一個對象放在當前的ViewPager中 public Object instantiateItem(View arg0, int arg1){ ((ViewPager)arg0).addView(pageview.get(arg1)); return pageview.get(arg1); } }; //綁定適配器 viewPager.setAdapter(mPagerAdapter); } }
