为此仅使用下面给出的示例：
对于Instance，您将添加一些字符串添加到列表中

所以创建一个这样的ListArray

  ArrayList< String> listItems = new ArrayList< String>（）; 
 

现在每当你想添加一些字符串到列表只是做这个事情

  EditText editText =（EditText）findViewById（R.id.edit）; 
 listItems.add（我的字符串）; OR 
 listItems.add（editText.getText.toString（））; //如果您从editText获取字符串值并将其添加到列表中，则会变为
 

使用此Xml内在main.xml中的线性布局

 < EditText android：id =@ + id / edit
 android ：layout_width =fill_parent
 android：layout_height =wrap_content/> 
 

现在，当您动态添加一个项目时，请调用此

  adapter.notifyDataSetChanged（）; 
 

上面将更新您的列表并显示已更新的列表。

在这些教程中，您可以将String []替换为ArrayList在答案顶部给出，当你想添加任何项目时，只需使用第二个代码片段。

I want to make a dynamic list view which gets the user credentials when I login for the first time and displays it in a list the next time I start the app. I know how to send the username from one intent to another. i haven't focused on the SQLite part yet, will do that later. I'm facing problems in creating the dynamic list view. Found one very useful thread - Dynamically add elements to a listView Android

he used a button on the screen and called the method onClick to populate the list. Can i do it without the button? I want it to automatically happen once i am able to login. how can i use the statements in my code?

listItems.add(value);
adapter.notifyDataSetChanged();

here value is the username i am getting from some other intent.
please help. thanks!

For this Just use the example given below: For Instance you are Adding Some Strings into your List

So Create a ListArray like this

ArrayList<String> listItems = new ArrayList<String>();

now whenever you want to add certain string into list just do this thing

  EditText editText = (EditText) findViewById(R.id.edit);
  listItems.add("my string");  OR
  listItems.add(editText.getText.toString()); //incase if you are getting string value from editText and adding it into the list

Use this Xml inside your linear layout in main.xml

  <EditText android:id="@+id/edit"
     android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>

Now when you have added one item dynamically then call this

  adapter.notifyDataSetChanged();

The above will update your list and display the upadted list.

For more info about this see the following links:

In these tutorials you can replace String[] with ArrayList as given at the top of the answer ook and when you want to add any item just simply use the second code snippet.
