我不知道您是否只能通过代码看到这一点......但是如果班上没有onClick我的服装适配器，什么都不会发生......安卓不使用"项目点击监听器"
但它确实适用于"点击"方法....
问题是：我没有我真正需要的职位......
希望有人能帮助我！谢谢大家！
您可以使用此事件接收有关正在选中/取消选中复选框的通知
cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
}
}
使用复选框 setOnCheckedChangeListener 事件。
试试这样...
CheckBox ChkBx = ( CheckBox ) findViewById( R.id.checkbox);
ChkBx.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
if ( isChecked )
{
// perform logic
}
}
});
您可以使用以下内容：
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(),
"Click ListItem Number " + position, Toast.LENGTH_LONG)
.show();
}
});
或者您可以将位置保存为标签以checkbox并检查checkbox clicklistener
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
// ur code...
**cb.setTag(position);**
row.setOnClickListener(this);
return row;
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
**int position = v.getTag();** //cast & check for Tag not null too.
Toast toast = Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
toast.show();
}
