将联系人添加到列表视图？
我有一个 ListView 和一个联系人选择器。我想要做的是，当我选择一个联系人时，我希望该联系人显示在列表视图中并保存在该列表视图中。到目前为止，我已经有了
ListView emailEntry = (ListView) findViewById(R.id.list);
emailEntry.setFilterText(Number);
if (Number.length() == 0) {
Toast.makeText(this, "No number found for contact.",
Toast.LENGTH_LONG).show();
}
This is Java 文本，其中数字被调用到列表视图中，
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/list"
/>
这显然是我的.XML 文件。
我没有强制关闭。问题是联系人没有被调入列表视图
I have a ListView and I have a contact picker. What I want to do is when I pick a contact I want the contact to show up in a list view and be saved in that list view. so far I have
ListView emailEntry = (ListView) findViewById(R.id.list);
emailEntry.setFilterText(Number);
if (Number.length() == 0) {
Toast.makeText(this, "No number found for contact.",
Toast.LENGTH_LONG).show();
}
This is the Java text were the number gets called into the list view
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/list"
/>
this is obviously my .XML file.
I get no force closing. the problem is the contact doesn't get called into the list view

您能否提供有关您正在尝试做什么的更多信息？您的数据源是什么？
我从来没有使用过ListView。结果，我可能没有抓住要点，但这是我的两分钱。
基于我的粗浅假设，为什么不使用 ListActivity 和自定义 (List)Adapter 来显示数据？然后你可以实现 onListItemClick() 并使用 startActivity() （具有正确的意图）或触发祝酒或任何有用的东西。我的观点是，您的问题是一个以数据为中心的问题，而不是以视图为中心的问题。

Could you provide more information about what you are trying to do? What is your data source?
I have never used ListView. As a consequence, I probably missed the point but here is my two cents.
Based on my humble assumptions, why don't you use a ListActivity and a custom (List)Adapter to display your data? Then you could implement onListItemClick() and use startActivity() (with the proper intent) or fire a toast or whatever is usefull. My opinion is that your problem is a data-centric problem, not a view-centric one.
