android - 如何在 ViewPager 中添加多个 TextView 或其他 View

Question

我想在我的 ViewPager 中添加 2 个或多个 TextView。但我不知道那个问题。太复杂了。

我的第二个 TextView 资源来自 tipler 数组。

这是我的Fragment.java

public class YaklasanlarFragment extends Fragment {

CircularProgressBar c3;

ViewPager viewPager = null;
String bilgiler[] = {"34 YNS 54","54 E 2554"};
String tipler[] = {"Muayene Tarihi","Sigorta Tarihi"};

public  YaklasanlarFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view= inflater.inflate(R.layout.activity_yaklasanlar_fragment, container, false);
    viewPager = (ViewPager) view.findViewById(R.id.viewPager);
    viewPager.setAdapter(new MyAdapter());
    return view;
}

class MyAdapter extends PagerAdapter{

    @Override
    public int getCount()
    {
        return bilgiler.length;
    }

    @Override
    public Object instantiateItem(View container, int position)
    {
       TextView plaka = new TextView(getActivity());
        plaka.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        plaka.setText(bilgiler[position]);
        ((ViewPager) container).addView(plaka, 0);
        return plaka;


    }
}

请参阅下面的代码，说明我们如何将 TextView 动态添加到 ViewPager 中。下面是 Adapter 类，你需要将 Adapter 设置到 ViewPager 中。

import android.content.Context;
import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class CustomPagerAdapter extends PagerAdapter {

    String bilgiler[] = {"34 YNS 54","54 E 2554"};
    String tipler[] = {"Muayene Tarihi","Sigorta Tarihi"};
    private Context mContext;

    public CustomPagerAdapter(Context context) {
        mContext = context;
    }

    @Override
    public Object instantiateItem(ViewGroup collection, int position) {
        //if Length of both array's  (bilgiler and tipler) Always remains same then we can do code like below.
    String modelObject = bilgiler[position] + tipler[position];
    LayoutInflater inflater = LayoutInflater.from(mContext);
    LinearLayout linearLayout = new LinearLayout(mContext);
    linearLayout.setOrientation(LinearLayout.HORIZONTAL);
    TextView textView = new TextView(linearLayout.getContext());
    textView.setText(modelObject);
    linearLayout.addView(textView);
    Button button = new Button(linearLayout.getContext());
    linearLayout.addView(button);
    collection.addView(linearLayout);
    return linearLayout;
    }

    @Override
    public void destroyItem(ViewGroup collection, int position, Object view) {
        collection.removeView((View) view);
    }

    @Override
    public int getCount() {
        return bilgiler.length;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }
}
