当我点击btnMeat时，只显示黑页。我想显示片段页面。我真的很困惑。
我的主页：
public class Main extends Activity {
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.main);
Button btnMeat=(Button)findViewById(R.id.meat);
btnMeat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
Intent intent=new Intent(Main.this,MeatList.class);
startActivity(intent);
}
catch (Exception ex){
Toast.makeText(getApplicationContext(),ex.getMessage(),Toast.LENGTH_LONG).show();
}
}
});
meatList：
public class MeatList extends FragmentActivity {
public void OnCreate(Bundle bundle){
super.onCreate(bundle);
setContentView(R.layout.Meatlist);
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpagerMeat);
viewPager.setAdapter(new MyAdapter(getSupportFragmentManager()));
}
public class MyAdapter extends FragmentPagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new MeatList1();
case 1:
return new MeatList2();
default:
return null;
}
}
@Override
public int getCount() {
return 2;
}
}
}
meatList1：
public class MeatList1 extends Fragment {
public void OnCreate(Bundle bundle){
super.onCreate(bundle); }
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
try {
RelativeLayout relativeLayout = (RelativeLayout) inflater.inflate(R.layout.meatlist1,container,false);
return relativeLayout;
}
catch (Exception e){
Toast.makeText(getActivity().getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
return null;
}

答案 0 :(得分：0)
我写过OnCreate（）而不是onCreate（）; public void OnCreate（Bundle bundle）{ super.onCreate（束）;
