Android: Use instance of control GridView _android

If it is a list (single row multiline form) the use of ListView, if it is a multiline multiple-column mesh form of precedence for the GridView.

<?xml version= "1.0" encoding= "Utf-8"?> <gridview xmlns:android=
"http://schemas.android.com/apk/res/" Android "
  android:layout_width=" match_parent "
  android:layout_height=" match_parent ">
  

</ Gridview>

Some properties of Girdview:

• android:numcolumns= "Auto_fit"--------the number of columns is set to Automatic
• Android:columnwidth= "90DP",----------the width of each column, i.e. the width of the item
• Android:stretchmode= "columnWidth"------Zoom and column size sync
• android:verticalspacing= "10DP"----------vertical margins
• android:horizontalspacing= "10DP"-------horizontal margin

1, prepare the data source

2. New Adapter

3. Load Adapter
