我使用ViewPagerIndicator像大多数流行的应用程序一样获取WalkThrough。但我无法理解如何在 ViewPager 中添加图片,其中显示了如何使用该应用程序。
我想要的就是这些走过。
到目前为止我得到了什么。
我不知道
欢迎任何指导。

由于这个问题很老,我只想写一个简短的一般准则:
要使用内容填充viewpager,可以将片段添加到适配器,然后将适配器设置为viewpager。你可以在片段中做任何布局,放置图像/文本等。

正如Inteist建议的那样,可以将任何布局放在片段中并将该片段提供给适配器。
片段:
public final class SelectModelFragment extends Fragment {
private static final String KEY_CONTENT = "SelectModelFragment:Content";
private static String TAG = SelectModelFragment.class.getSimpleName();
private SelectModel mSelectModelObj;
private CircularImageView mImageView;
public static SelectModelFragment newInstance(SelectModel obj) {
SelectModelFragment fragment = new SelectModelFragment();
fragment.mSelectModelObj =obj;
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if ((savedInstanceState != null) && savedInstanceState.containsKey(KEY_CONTENT)) {
mSelectModelObj = savedInstanceState.getParcelable(KEY_CONTENT);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_select_model, container, false);
mImageView = (CircularImageView)view.findViewById(R.id.fragment_select_model_iv);
return view;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putParcelable(KEY_CONTENT, mSelectModelObj);
}
}
片段适配器:
public class SelectModelAdapter extends FragmentPagerAdapter {
ArrayList<SelectModel> mList;
private int mCount;
private static final String TAG = SelectModelAdapter.class.getSimpleName();
public SelectModelAdapter(FragmentManager fm, ArrayList<SelectModel> mList) {
super(fm);
this.mList = mList;
mCount = mList.size();
}
@Override
public Fragment getItem(int position) {
return SelectModelFragment.newInstance(mList.get(position));
}
@Override
public int getCount() {
return mCount;
}
@Override
public CharSequence getPageTitle(int position) {
return TAG;
}
public void setCount(int count) {
if (count > 0 && count <= 10) {
mCount = count;
notifyDataSetChanged();
}
}
}
活动:ViewPager具有片段适配器,用于提供片段。
public class SelectModelActivity extends BaseSliderActivity {
private ViewPager mPager;
private SelectModelAdapter mAdapter;
private ArrayList<SelectModel> mList;
private void setAdapter() {
mAdapter = new SelectModelAdapter(getSupportFragmentManager(), mList);
mPager.setAdapter(mAdapter);
mIndicator.setViewPager(mPager);
}
}
