android - 如何调整图像视图？

Question

我已经从模拟器的 sdcard 中检索图像并添加到我的网格视图中。但它们没有以正确的方式显示。！[在此处输入图像描述][1]

你能帮我吗..我还发布了我的 ImageAdapter.java 请提出任何更改..谢谢

public class ImageAdapter extends BaseAdapter 
{
    ArrayList<Images> array=new ArrayList<Images>();

    Context mContext; 
    private LayoutInflater mInflater; 



    public ImageAdapter(Context c,ArrayList<Images> arr) 
    {
        mContext = c;  
        array=arr;
        mInflater = LayoutInflater.from(mContext);
        Log.e("","adapter con");
    }


    public int getCount()
    {
            Log.e("Count",""+array.size());
        return array.size();
    }

    public Object getItem(int index)
    {
         //return 0;
        return array.get(index);
    }

    public long getItemId(int index) 
    {

        return index;
    }
    public View getView(int position, View convertView, ViewGroup parent) {
        //    RelativeLayout.LayoutParams layoutParams =new //RelativeLayout.LayoutParams(30, 30);

        ImageView imageView = new ImageView(mContext);

        Images i=array.get(position);
        imageView.setImageBitmap(i.getBitmap());

        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        imageView.animate();
       //       imageView.setLayoutParams(layoutParams);



        return imageView;
    }
}

Answer 1

你已经定义了布局参数 LayoutParam layoutparam = new LayoutParams(LayoutParams.FILL_Parent,LayoutParams.FILL_Parent); imageView.setLayoutParams(layoutParams);

Answer 2

试试这个。这应该工作，

        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
