Android Small Notes

A ListView is a data control that can display data read from a database and use TextView to implement output.

ImageView is a control for displaying pictures that you can get to a picture in the database to display the output.

arrayadapter Text adapter: Gets the data values in the collection, array, and, in particular, loads the adapter to get the contents of the adapter to output. Ways to implement the Arrayadapter adapter:

//Create an array first

private string[] CType = new string[]{"Content 1", "Content 2", "Content 3"};

//Gets the value in the array through the text adapter

arrayadapter<string> adater =

New Arrayadapter<string> (this,android. R.id.simple_spinner_item,ctype);

//Set the option style for the adapter when the list box is pulled down

Adapter.setdropdownviewresource (Android. R.layout.simple_spinner_dropdown_item);

//Load adapter Get results

Spinner.setadapter (adapter);

Simpleadapter Graphics Adapter : Used for matching correspondence between pictures and text.

//Create an array to hold the text and an array to hold the picture first

Private string[] CType = new string[]{"Content 1", "Content 2", "Content 3"};

private int img = new Int[]{r.drawable.logo,r.drawable.logo,r.drawable.logo,};

//Graphics adapter

list<map<string,object>> datas = new arraylist<map<string,object>> ();

for (int i = 0;i<object<length;i++) {

map<string,object> map = new map<string,object> ();

Map.put ("image", img[i]);

Map.put ("name", Ctype[i]);

Datas.add (map);

}

Simpleadapter adapter = new Simpleadapter (This,datas,r.layout.list_item,

New string[]{"image", "Name"},new int[]{r.id.iv_logo,r.id.tv_name});

//Load Adapter

Lv.setadapter (adapter);

There's also a custom adapter that hasn't been worked on, and will continue tomorrow! 650) this.width=650; "src=" Http://img.baidu.com/hi/bobo/B_0054.gif "alt=" B_0054.gif "/>
