Question

很抱歉这个简单的问题，但过去一周一直在与这个问题作斗争。如果有人可以通过在按钮监听器的onclick内部编码来解决这个问题我将不胜感激，当点击它时，它共享片段中的内容或扩展fragmentStatePageAdapter的适配器。

我的活动

public class MainActivity extends AppCompatActivity {
    private Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        final Adapter devicePageAdaptor = new Adapter(getSupportFragmentManager(), getApplicationContext());
        ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
        viewPager.setAdapter(devicePageAdaptor);
        button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
}

片段

public class fragment extends Fragment {

    public static final String ProverbKey = "proverbKey" ;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_device, container, false);


        Bundle bundle = getArguments();

        if (bundle != null) {
            String proverb = bundle.getString(ProverbKey);


            setValues(view,proverb);

        }
        return view;
    }

    private void setValues(View view, String proverb) {
        TextView textView = (TextView) view.findViewById(R.id.textView_proverb);
        textView.setText(proverb);



    }

}

扩展fragmentStateAdapter的适配器

public class Adapter extends FragmentStatePagerAdapter {

    String[] proverb;


    public Adapter(android.support.v4.app.FragmentManager fm,Context context) {
        super(fm);
        Resources resources = context.getResources();
        proverb = resources.getStringArray(R.array.proverb);

    }

    @Override
    public android.support.v4.app.Fragment getItem(int position) {
        Bundle bundle = new Bundle();
        bundle.putString(fragment.ProverbKey, proverb[position]);

        fragment deviceFragment = new fragment();
        deviceFragment.setArguments(bundle);
        return deviceFragment;

    }

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

我的每个片段中的String Array都被命名为谚语

<string-array name="proverb">
    <item>A young idler, an old beggar.</item>
    <item>Action speaks louder than words.</item>
    <item>A hungry man is an angry man.</item>
    <item>A living dog is better than a dead lion.</item>
    <item>A hedge between keeps friendship green.</item>
    <item>A heavy purse gives to a light heart.</item>
    <item>A handful of patience is worth more than a bushel of brains</item>
    <item>A guilty conscience needs no accuser.</item>
    <item>A growing youth has a wolf in his belly.</item>
    <item>A good name is better than a good face.</item>
    <item>A good beginning makes a good end.</item>
    <item>A drop of ink may make a million think.</item>
    <item>A dry March, a wet April and a cool May may fill barn and cellar and bring much hay.</item>
</string-array>

Answer 1

 //Global Variable
  String[] proverb;
 //Init on onCreate()
proverb = resources.getStringArray(R.array.proverb);
button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            int pos = viewPager.getCurrentItem();
            String itemToShare = proverb[pos];
            share(itemToShare);

        }
    });

    private void share(String item) {
    Intent share = new Intent(android.content.Intent.ACTION_SEND);
    share.setType("text/plain");
    share.putExtra(Intent.EXTRA_SUBJECT, "Title Of The Post");
    share.putExtra(Intent.EXTRA_TEXT, item);
    startActivity(Intent.createChooser(share, "Sharing Item!"));

}
