我有一个JSON数组,我想对它进行排序,具体取决于名称和字母顺序.我的Json如下.

我有一个应用程序,我正在使用Landscape和potrait模式.我在我的每个活动中都使用了android:configChanges ="orientation | keyboardHidden".因此,当我在设备2.3上运行它时,它完全正常工作并且活动没有重新启动.但是当我在android 4.0及更高版本中打开相同的应用程序时,只要方向发生变化,活动就会重新启动.这是我的xml文件.

我有一个ImageView,我正在为其分配一个使用zxing库生成的qr代码.

 <ImageView
        android:id="@+id/qrcode"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="15dp"
        android:layout_marginTop="86dp" />

这是我的imageview,我想首先以字节为单位转换此ImageView,然后转换为bytearray.我能实现吗？

我有一个png可绘制文件夹中的图像,我想在中使用该png图像pdf.我itextpdf.jar用来创造pdf.我搜索了解决方案,但我无法弄明白.
