我想做的是“简单”,我点击列表视图中的某个项目,会发生一些事情。我再次点击一个项目,并根据它是否是我点击的相同项目或另一个项目,它会做其他事情。你能帮助我吗?
public OnItemClickListener listener = new OnItemClickListener() {
int i = 1;
int p;
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id){
loaddetails(pf, position);
i++;
p=position;
if(i%2 == 0 ){
details.startAnimation(AnimationUtils.loadAnimation(getApplicationContext(), R.anim.enter));
details.setVisibility(View.VISIBLE);
}else{
details.startAnimation(AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fade2));
details.setVisibility(View.GONE);
}
}
};
我的例子是这样的,我点击一个项目,细节出现,只有当我点击相同的项目时,细节必须消失。

保持点击最后一项的ID占位符:
全班同学:
int lastID = -1;
然后:
public OnItemClickListener listener = new OnItemClickListener() {
int i = 1;
int p;
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id){
loaddetails(pf, position);
i++;
p=position;
if(lastID == id || lastID == -1){
details.startAnimation(AnimationUtils.loadAnimation(getApplicationContext(), R.anim.enter));
details.setVisibility(View.VISIBLE);
}else{
details.startAnimation(AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fade2));
details.setVisibility(View.GONE);
}
lastID = id;
}
};
