I want to know how to add a new text view to appearing ListView in android, ( for example. when I click on some button a new list item is added to the list view )?

推荐答案

您只需将对象添加到包含的列表视图显示的对象的容器。那你告诉ListView控件适配器的变化已经发生：

You simply add the object to the container that contains the objects displayed by the listview. Then you tell the listView adapter that a change has occured:

public void onClick(View v) {
list.add(someObject);
((ArrayAdapter<Object>) listView.getAdapter()).notifyDataSetChanged();
setContentView(R.layout.list_view);
