这是我的代码...
public class StockActivity extends Activity {
public ListAdapter listadapter;
private StockPageAdapter myAdapter;
private ViewPager myPager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.main);
this.myAdapter = new StockPageAdapter(this);
this.myPager = (ViewPager)super.findViewById(R.id.pager);
this.myPager.setAdapter(myAdapter);
}
这是一个ListAdapter具有ViewPager通过滚动列表。我正在BaseAdapter使用此代码扩展和扩大视图...
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.row, null);
有人可以帮助我了解问题所在。
您的XML在布局文件中是什么样？如果你只是把
<ViewPager
android:layout_width="..."
android:layout_height="..." />
您的应用程序将崩溃，因为ViewPager它不与其他小部件一起位于核心SDK软件包中，而是位于支持库中。您需要输入全限定名称
<android.support.v4.view.ViewPager
android:layout_width="..."
android:layout_height="..." />
另外，正如其他人提到的那样，请确保支持库JAR已正确包含在您的项目中。
