本文详细解析了Viewcom.example.listviewtest.FruitAdapter.getView方法的工作原理。此方法用于获取ListView中指定位置的数据视图，可以通过手动创建视图或从XML布局文件中加载。当视图加载时，ListView会应用默认的布局参数，除非使用特定的方法指定了根视图并阻止了其附加到根。文章还介绍了该方法的参数和返回值。

com.example.listviewtest. .getView(int position, convertView, parent)

@ Override

Get a View that displays the data at the specified position in the data set. You can either create a View manually or inflate it from an XML layout file. When the View is inflated, the parent View (GridView, ListView...) will apply default layout parameters unless you use android.view.LayoutInflater.inflate(int, android.view.ViewGroup, boolean) to specify a root view and to prevent attachment to the root.

Overrides: getView(...) in ArrayAdapter

Parameters:

position The position of the item within the adapter's data set of the item whose view we want.

convertView The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)).

parent The parent that this view will eventually be attached to

Returns:

A View corresponding to the data at the specified position.
