今天做获取用户接口信息,结构如下所示(UserIcon的值只是部分,不可用),有返回用户图片的信息(二进制),需要在页面显示,这里做下笔记
{ "UserCode":"admin", "UserName":"管理员", "UserIcon":"iVBORw0KGgoAAAANSUhEUgAAAIAAAACACAYAAADDPmHLAAAUCklEQVR4nO2da5RdZX3Gf88+l8kkk2SSyd0" }
1)直接在控件设置图片来源
<ImageButton android:id="@+id/img_in_pack_user_icon" android:layout_width="80dp" android:layout_height="120dp" android:background="@color/colorWhite" android:src="@drawable/icon_un_login128" android:scaleType="fitCenter" />
2)通过后台动态设置图片来源(安卓图片资源)
ImageButton imgUserIcon = findViewById(R.id.img_in_pack_user_icon); imgUserIcon.setImageResource(R.drawable.icon_male_doctor128);
3)通过后台动态设置图片来源(二进制字符流转成图片)
3.1)将二进制字符流转成Bitmap方法
public static Bitmap convertStringToIcon(String outPut){ Bitmap bitmap = null; try{ byte[] bitmapArray; bitmapArray = android.util.Base64.decode(outPut, android.util.Base64.DEFAULT); bitmap = BitmapFactory.decodeByteArray(bitmapArray,0,bitmapArray.length); }catch (Exception ex){ ex.printStackTrace(); } return bitmap; }
3.2)调用转换方法并设置图片
String imgStream =
