Question

我有一个视图寻呼机应用程序正常工作。视图分页器在滑动后一次显示一个数组中包含不同的数据字符串。我有一个按钮，点击后应获取当前内容并将其传递给另一个活动，这是我的代码：

/*MainActivity*/
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get the view from viewpager_main.xml
        setContentView(R.layout.activity_main);

        btn = (Button) findViewById (R.id.button1);


        item = new String[] { "Apple", "Movie", "Melon", "pawpaw",
                "Jungle", "Forest" };



        // Locate the ViewPager in viewpager_main.xml
        viewPager = (ViewPager) findViewById(R.id.pager);
        // Pass results to ViewPagerAdapter Class
        adapter = new ViewPagerAdapter(this, item);
        // Binds the Adapter to the ViewPager
        viewPager.setAdapter(adapter);

        btn.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View arg0) {
                        // TODO Auto-generated method stub
                        Intent i = new Intent(getApplicationContext(), ContentActivity.class);
                        i.putExtra("Currentitem", item[0].toString());
                        startActivity(i);
                    }
                });


    }

以下是ViewPagerAdapter类

public class ViewPagerAdapter extends PagerAdapter {
    // Declare Variables
    Context context;
    String[] item;
    LayoutInflater inflater;

    public ViewPagerAdapter(Context context, String[] item) {
        this.context = context;
        this.quote = item;
    }


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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {

        TextView item;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View itemView = inflater.inflate(R.layout.activity_view_pager_adapter, container,
                false);


        txtitem = (TextView) itemView.findViewById(R.id.quote);


        txtitem.setText(quote[position]);




        ((ViewPager) container).addView(itemView);

        return itemView;

这应该可以正常工作：

 btn.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View arg0) {

            int currentItem =viewPager.getCurrentItem();

            Intent i = new Intent(getApplicationContext(), ContentActivity.class);
            i.putExtra("Currentitem", item[currentItem].toString());

            startActivity(i);
     }
  });

祝福。
