android - ViewPager OnItemClickListener

Question

我是 Viewpager 的新手，在阅读了 http://developer.android.com/reference/android/support/v4/view/ViewPager.html 之后从谷歌，我似乎无法在 viewPager.setOnItemClickListener(new OnItemClickListener() { 我们有其他选项来充当 Item Clicked 吗？

测试

viewPager.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                Intent i = new Intent(MainActivity.this, SingleItemView.class);
                i.putExtra("flag", flag);
                i.putExtra("position", position);
                startActivity(i);
            }

        });

错误:未为 ViewPager 类型定义方法 setOnItemClickListener(new AdapterView.OnItemClickListener(){})

ViewPager 没有 OnItemClick 回调方法。如果您想在每个页面上发生单击事件，则必须将监听器构建到适配器内的页面内容中。

类似这样的:

@Override
public Object instantiateItem(View collection, final int pos) { //have to make final so we can see it inside of onClick()
    LayoutInflater inflater = (LayoutInflater) collection.getContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);


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

    page.setOnClickListener(new OnClickListener(){
        public void onClick(View v){
            //this will log the page number that was click
            Log.i("TAG", "This page was clicked: " + pos);
        }
    });


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

您究竟需要什么将取决于您在 instantiateItem() 中所做的其他事情，您尚未发布，因此我无法给您更具体的答案。
