我有一个需要点击的新列表,但这个列表不起作用。onListItemClick 永远不会被调用。我的应用程序中有另一个按预期工作,但我不知道有什么区别。我见过人们说要改变焦点,但我已经尝试了很多不同的方法,但没有任何效果。所以这里有一些代码。
在职的:
@Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
// get the item that was clicked
v_ProjectInvestigatorSiteContact project = (v_ProjectInvestigatorSiteContact) this.getListAdapter().getItem(
position);
Intent myIntent = new Intent(this, Details.class);
myIntent.putExtra(res.getString(R.string.project), project);
startActivity(myIntent);
}// onListItemClick
不工作:
@Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
// get the item that was clicked
final v_SitePeople vSitePeople = (v_SitePeople) this.getListAdapter().getItem(
position);
AlertDialog.Builder builder = new AlertDialog.Builder(Share.this);
builder.setTitle(res.getString(R.string.forgot_password_check_dialog_title))
.setMessage(res.getString(R.string.share_check_dialog_text))
.setPositiveButton(res.getString(R.string.send), new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
sendShareEmail(vSitePeople);
}
}).setNegativeButton(res.getString(R.string.cancel), new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
// cancelled, so do nothing
}
});
AlertDialog msgBox = builder.create();
msgBox.show();
}// onListItemClick
