我正在获取图像数组作为响应，并在全屏显示并滑动它，但如果我的图像数组为null我需要禁用点击事件并阻止它进入下一个活动，我尝试了很多但不知道是什么在我的代码中出错。请按照我的代码进行操作.. https://stackoverflow.com/questions/27458980/how-to-send-response-to-next-activity/27498613?noredirect=1#comment43428525_27498613

检查您的数组长度，如果它不为零则启用onclicklistener ..
if(picarray.length != 0)
{
ucover.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
}

您可以检查您的arraylist的长度，然后根据该设置向用户发送消息
if(picarray.length()!=0)
{
ucover.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
}
else
{//show your message here
}
答案 2 :(得分：0)
您可以将侦听器设置为null以禁用onclick事件
ucover.setOnClickListener(null)
如果您想恢复点击活动，只需致电
ucover.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getApplicationContext(), Fullimage.class);
i.putExtra("images", USER_IMG);
startActivity(i);
}
});
