Java imageswitcher填充屏幕（但我不希望它这样做）[android]

我在我的寄存器片段中添加了一个imageswitcher，当用户选择他/她的性别时，图像会发生变化，但显示的图像太大，我无法缩放它。我使用的是scrollview，但Imageswitcher比屏幕大并不好。我尝试使用更小的图像，但结果是一样的。以下是我的XML：

将

ImageSwitchers

宽度更改为

wrap\u content

无效。我添加了代码以在.java文件中扩展它。它缩放了图像，但Imageswitcher仍然很大。在imageswitcher前后都有一个很大的空间。这是因为您将每个视图包装在一个线性布局中，这是错误的。嗯，我应该怎么做呢？删除所有具有一个子视图的视图组（线性布局），并将重力和填充/边距移动到视图本身。

....

cinsiyetSwitcher = (ImageSwitcher) rootView.findViewById(R.id.cinsiyetSwitcher);
            cinsiyetSwitcher.setFactory(new ViewFactory() {

                   @Override
                   public View makeView() {
                       ImageView imageView = new ImageView(getActivity());
                       imageView.setScaleType(ImageView.ScaleType.CENTER);
                       imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
                       return imageView;
                       }

                   });

            kizRadio = (RadioButton) rootView.findViewById(R.id.radio0);
            erkekRadio = (RadioButton) rootView.findViewById(R.id.radio1);

            kizRadio.setOnClickListener( new View.OnClickListener() {
                    public void onClick(View v)
                    {
                        degistir1(v);
                    }
            });

            erkekRadio.setOnClickListener( new View.OnClickListener() {
                public void onClick(View v)
                {
                    degistir2(v);
                }
            });

....

public void degistir1(View view)
{
      Animation in = AnimationUtils.loadAnimation(getActivity(),
      android.R.anim.slide_in_left);
      Animation out = AnimationUtils.loadAnimation(getActivity(),
      android.R.anim.slide_out_right);
      cinsiyetSwitcher.setInAnimation(in);
      cinsiyetSwitcher.setOutAnimation(out);
      cinsiyetSwitcher.setImageResource(R.drawable.kari);
}

public void degistir2(View view)
{
      Animation in = AnimationUtils.loadAnimation(getActivity(),
      android.R.anim.slide_out_right);
      Animation out = AnimationUtils.loadAnimation(getActivity(),
      android.R.anim.slide_in_left);
      cinsiyetSwitcher.setInAnimation(out);
      cinsiyetSwitcher.setOutAnimation(in);
      cinsiyetSwitcher.setImageResource(R.drawable.adam);
}
