我有一個需要點擊的新東西列表，但是這個不起作用。 onListItemClick永遠不會被調用。我的應用程序中有另一個按預期工作，我無法弄清楚有什麼不同。它發生在我身上，也許有衝突，因爲它們都使用提供的@ id/android：list，但它們處於不同的活動中，而且我還沒有發現其他人抱怨同一個問題，所以我不確定。使用@ id/android的Android多重列表：列表
這是一堆代碼。我將不勝感激任何建議。
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
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

這裏更多的是如何破碎的工作，以防萬一你想要更多的代碼。

非常感謝你的幫助。
根據要求提供更多代碼。

最重要的是您的活動都是從ListActivity擴展的，因爲一旦您在xml中提供了默認的android：id/list屬性，系統就會期望這些屬性。是這樣嗎？另外，在設置每個列表的地方共享代碼並設置適配器。 –
是的。它們都擴展了ListActivity。我將使用您要求的代碼編輯OP。 – erosebe
我會嘗試從行xml中的relativeLayout中移除重量。你不能在relativeLayout中使用體重。 – koso
