ビットマップをImageViewに設定した後、幅と高さの両方にwrap_contentを設定したいと思います。

imgSubsegment = (ImageView) findViewById(R.id.subsegment);

ViewGroup.LayoutParams imageViewParams = new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);

......................................

imgSubsegmentSensor.setImageBitmap(bmpSubsegmentSensor);
imgSubsegmentSensor.setLayoutParams(imageViewParams);

与えているjava.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.view.ViewGroup$MarginLayoutParams

私のコードの問題は何ですか？の解き方？

    imgSubsegment = (ImageView) findViewById(R.id.subsegment);

    ViewGroup.MarginLayoutParams imageViewParams = new ViewGroup.MarginLayoutParams(
        ViewGroup.MarginLayoutParams.WRAP_CONTENT,
        ViewGroup.MarginLayoutParams.WRAP_CONTENT);

    ......................................

    imgSubsegmentSensor.setImageBitmap(bmpSubsegmentSensor);
    imgSubsegmentSensor.setLayoutParams(imageViewParams);
