对于使用ImageView或TextView或EditText比例尺的人来说，效果很好.使用

For those who Use ImageView or TextView or EditText Scale works perfectly. Use

android:scaleX="-1" //To flip horizontally or
android:scaleY="-1" //To flip vertically

或尝试

android:rotationX="180" // for horizontal
android:rotationY="180" // for vertical

或仅rotation="180"表示垂直

android:rotation="180" // for vertical
