我很容易使用textview但textview与imageview像联系人名称，数字和图像显示排序列表我痛苦与我搜索了许多博客但没有成功请帮助....
public class Listmain extends ListActivity
{
@Override public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
try
{
Data_baseActivity db=new Data_baseActivity(this);
db.open();
InputStream is;
Cursor cursor =db.getAllContacts1();
int len=cursor.getCount();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.rowlayout, cursor, new String[] { "image", "name"}, new int[] { R.id.icon, R.id.label});
adapter.setViewBinder(new ProductViewBinder());
setListAdapter(adapter);
db.close();
}
catch(Exception e)
{
Toast.makeText(this, e.toString()+" error", Toast.LENGTH_LONG).show();
}
}
}
public class ProductViewBinder implements ViewBinder
{
public boolean setViewValue(View view, Cursor cursor, int columnIndex)
{
try
{
if (view instanceof ImageView)
{
byte[] result = cursor.getBlob(3);//my image is stored as blob in db at 3
Bitmap bmp = BitmapFactory.decodeByteArray(result, 0, result.length);
ImageView im=(ImageView)findViewById(R.id.icon);
im.setImageBitmap(bmp);
return true;
}
}
catch(Exception e)
{
Toast.makeText(Listmain.this, e.toString()+" err", Toast.LENGTH_LONG).show();
}
return false;
}
}
答案 0 :(得分：0)
试试这样：
cr.getBlob(cr.getColumnIndex("Image")) //where "Image" is column name.
我用过它并且有效。
如果不起作用。请发布您toast message
exception
答案 1 :(得分：0)
simpleCusorAdapter。context, layout, cursor, from, to this.imageContainer=container。答案 2 :(得分：0)
