Question

我正在尝试在ViewPager中实现我的Fragment，以便每个页面可以打开不同的活动，但到目前为止，onClickListener没有响应，也从未调用过。

以下是我在PagerAdapter：

下实施的方法

@Override
public Object instantiateItem(View collection, final int pos) {
    LayoutInflater inflater = (LayoutInflater) collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View page = inflater.inflate(R.layout.activity_jeans, null);

    page.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
            startActivity(new Intent(getActivity(),JeansActivity.class));
        }
    });

    ((ViewPager) collection).addView(page, 0);
    return page;
}

我正在阅读关于ViewPager的{{3}}，但未能找到有关如何正确实施该问题的任何帮助。

以下是我的Fragment菜单中的完整代码：

        mViewPager.setAdapter(mSectionsPagerAdapter);

        return rootView;


    }

            }
        }

        public PlaceholderFragment() {

            ImageView jeans = (ImageView) rootView.findViewById(R.id.imageView1);
            jeans.setImageResource(imagen);

            jeans.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {

                    startActivity(new Intent(getActivity(),JeansActivity.class));

                }

            });

            return rootView;
        }
    }

}

对任何其他文档的任何帮助或参考将不胜感激

在PlaceHolderFragment onCreateView()回调中，您只需检查Fragments参数上的图片ID。使用该资源ID，您可以根据该值启动Activity：

jeans.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {

        Intent activityIntent = new Intent();

        Intent intent = new Intent();

        switch(imagen){
        case R.drawable.jeans:
            intent = new Intent(getActivity(), JeansActivity.class);
            break;
        case R.drawable.blusas:
            intent = new Intent(getActivity(), BlusasActivity.class);
            break;
            R.drawable.leggings:
                intent = new Intent(getActivity(), LegginsActivity.class);
            break;
        }

        startActivity(intent);
    }
});

使用ViewPager打开不同的活动
