我使用了来自https://code.google.com/p/android-amazing-listview/
的android-amazing-listview我添加了一个setOnItemClickListener，但它不起作用。有人可以帮我一把：

lsComposer.setLoadingView(getLayoutInflater().inflate(R.layout.loading_view, null));
lsComposer.setAdapter(adapter = new PaginationComposerAdapter());
adapter.notifyMayHaveMorePages();

答案 0 :(得分：0)
这种做法是错误的。
您在onCreate中为setOnItemClickListener撰写ListView，
lsComposer.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// action
}
});
或者您将其更改为onClickListenner内的其他视图Adapter
示例：
res.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent in = new Intent(getApplicationContext(), SingleItemView.class);
in.putExtra("id", composer.id);
in.putExtra("title", composer.name);
in.putExtra("s_desc", composer.year);
in.putExtra("img", composer.img);
Log.e("onItemClick PRINT THE URL 777777777777", "onItemClick: ");
startActivity(in);
}
});
