我有一个使用以下适配器的viewpager,在加载后,第一个视图显示为空,但事实并非如此.如果我滚动到下一个视图,然后向后滚动,我可以看到内容.

import android.content.Context;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.widget.TextView;
import java.util.ArrayList;

public class MyPagerAdapter extends PagerAdapter {

    Context context;

    public ArrayList<TextView> mViews;

    int layoutResourceId;

    public MyPagerAdapter(Context context) {
        mViews = new ArrayList<TextView>();

    }

    @Override
    public void destroyItem(View view, int arg1, Object object) {
        ((ViewPager)view).removeView((View)object);
    }

    @Override
    public void finishUpdate(View arg0) {

    }

    @Override
    public int getCount() {
        return mViews.size();
    }

    @Override
    public Object instantiateItem(View view, int position) {
        View myView = mViews.get(position);
        ((ViewPager)view).addView(myView);
        return myView;
    } …
