}
3个按钮正常工作，但点击时不会触发3个ImageView
答案 0 :(得分：0)
尝试使用此语法，看看它是否有效：
iv_fb.setOnClickListener(new view.OnClickListener{ public void onClick()
{
Toast.makeText(context, "google", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context, MyService.class);
intent.putExtra("type", "google");
context.startService(intent);
} });
