ImageView.setPivot屬性不響應數據

我在屏幕上旋轉圖像時總是出現問題，我總是在相同的軸心點上旋轉，我知道這是（0,0），這就是我想要的實現它：ImageView.setPivot屬性不響應數據

private Evidence setVehiclePosition (String sCombination, PointF startPoint, 
PointF endPoint, int position, final Evidence myEvidence) { 
    myEvidence.geteImage().setOnTouchListener(this); 

    imgViewSelected.setPivotX(imgViewSelected.getWidth()); 
    imgViewSelected.setPivotY(imgViewSelected.getHeight()); 
    double angle = MyTrigonometry.angleTwoVectors(startPoint, endPoint); 
    PointF imageLocation = null; 

    switch (sCombination){ 

     case "C1": 
      //angle += 180; 
      break; 
     case "C2": 
      angle += 90; 
      break; 
     case "C3": 
      break; 
     case "C4": 
      //angle += 270; 
      break; 
    } 

    imgViewSelected.setRotation((int) angle); 
    imageLocation = 
MyConvert.MtsToPixs(MyTrigonometry.getCornerrPoint(startPoint, endPoint, 
MyConvert.PixsToMts(myEvidence.geteImage().getHeight()))); 

    imgViewSelected.setTranslationX((imageLocation.x + 
MyConvert.getOffset().x));                  
    imgViewSelected.setTranslationY(MyConvert.getScreenResolution().y - ((imageLocation.y) + MyConvert.getOffset().y)); 
}

不管什麼我把setPivot（東西），它只是保持在這個問題上旋轉過同樣的觀點，任何提示裏面？
