(一)首先定义布局
android:id="@+id/id_layout_movie"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
(二)加载图片显示时获取到布局文件
RelativeLayout rl_Movie = (RelativeLayout) findViewById(R.id.id_layout_movie)
(三)依次循环服务器获取的图片数据,一张一张设置图片显示的位置
//newWidth为图片显示的宽度,newHeight为图片显示的高度
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams( newWidth, newHeight)
设置lp1.leftMargin和lp1.topMargin的值
(四)最后设置rl_Movie.addView(iv, lp1)将图片加入布局文件中
给你提供个ACCESS版的VB代码,使用时调用这些过程即可:'使用ADODB.Stream来保存/读取图像文件到数据库
'引用Microsoft ActiveX Data Objects 2.5 Library及以上版本
'保存文件到数据库中
Sub SaveFile()
Dim Stm As New ADODB.Stream
Dim Cnn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim strCnn As String
strCnn = "Provider=Microsoft.Jet.OLEDB.4.0Persist Security Info=FalseData Source=" &_
App.Path &"\DB1.mdb"
Cnn.Open strCnn
'读取文件到内存(二进制模式)
With Stm
.Type = adTypeBinary
.Open
.LoadFromFile App.Path + "\Image1.bmp"
End With
With rs
.Open "SELECT * FROM TABLE1", Cnn, 1, 3
.AddNew
.Fields("IMAGE") = Stm.Read
.Update
End With
rs.Close
Stm.Close
Set rs = Nothing
Set Cnn = Nothing
Set Stm = Nothing
End Sub
'从数据库中读取图像文件
Sub ReadFile()
Dim Stm As New ADODB.Stream
Dim Cnn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim strCnn As String
strCnn = "Provider=Microsoft.Jet.OLEDB.4.0Persist Security Info=FalseData Source=" &_
App.Path &"\DB1.mdb"
Cnn.Open strCnn
rs.Open "SELECT IMAGE FROM TABLE1 WHERE ID = 18", Cnn, adOpenKeyset, adLockReadOnly
'保存到文件
With Stm
.Mode = adModeReadWrite
.Type = adTypeBinary
.Open
.Write rs("IMAGE")
.SaveToFile App.Path + "\Image2.bmp"
End With
'显示图片
Picture1.Picture = LoadPicture(App.Path + "\Image2.bmp")
rs.Close
Stm.Close
Set rs = Nothing
Set Cnn = Nothing
Set Stm = Nothing
End Sub
