Question

我正在使用Android Studio 1.2.2并尝试为我的某项活动实施标签。我添加了所有代码，但似乎没有在手机上获得任何输出。我不需要ActionBar，只需要SlidingTabLayout，但是当我跑步时它不会显示除空白屏幕以外的任何内容。

Iphone6Activity.java

package com.hashmi.omar.vodafonestore;


import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;


public class Iphone6Activity extends Activity {



private ViewPager mPager;

private SlidingTabLayout mTabs;




@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_iphone6);

    //Sets font for text
    //Typeface vodaLt = Typeface.createFromAsset(getAssets(), "VODAFONELT.TTF");
    //TextView vodaHeading = (TextView) findViewById(R.id.textView10);
   // vodaHeading.setTypeface(vodaLt);

    mPager = (ViewPager) findViewById(R.id.ip6pager);

    //mPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));

    mTabs = (SlidingTabLayout) findViewById(R.id.ip6tabs);

    mTabs.setViewPager(mPager);


}




class MyPagerAdapter extends FragmentPagerAdapter{

    String[] tabs;

    public MyPagerAdapter(FragmentManager fm) {
        super(fm);
        tabs=getResources().getStringArray(R.array.tabs);
    }


    @Override
    public Fragment getItem(int position) {
        MyFragment myFragment=MyFragment.getInstance(position);
        return myFragment;
    }


    @Override
    public CharSequence getPageTitle(int position){
        return tabs[position];
    }


    @Override
    public int getCount() {
        return 3;
    }
}

public static class MyFragment extends Fragment{
    private TextView textView;
    public static MyFragment getInstance(int position){
        MyFragment myFragment = new MyFragment();
        Bundle args = new Bundle();
        args.putInt("position", position);
        myFragment.setArguments(args);
        return myFragment;
    }


    @Override

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup     container, @Nullable Bundle savedInstanceState) {
        View layout=inflater.inflate(R.layout.fragment_my, container,     false);
        textView= (TextView) layout.findViewById(R.id.position);
        Bundle bundle=getArguments();
        if(bundle!=null)
        {
            textView.setText("The page selected is "+bundle.getInt("position"));
        }

        return layout;
    }
}

}

Answer 1

您没有使用MyPagerAdapter类。取消注释此行以设置ViewPager的适配器：

//mPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));

SlidingTabLayout不显示在输出上
