【中文标题】android - 自定义圆形 imageView 得到错误膨胀【英文标题】：android - custom round imageView get error inflating 【发布时间】：2015-05-26 01:38:33 【问题描述】：我有一个列表视图，我使用自定义布局来制作行。在每一行中，我都有自定义 imageView 用于舍入图像。这是课程：
public class RoundedImageView extends ImageView
public RoundedImageView(Context context)
super(context);
// TODO Auto-generated constructor stub
public RoundedImageView(Context context, AttributeSet attrs)
super(context, attrs);
public RoundedImageView(Context context, AttributeSet attrs, int defStyle)
super(context, attrs, defStyle);
@Override
protected void onDraw(Canvas canvas)
Drawable drawable = getDrawable();
if (drawable == null)
return;
if (getWidth() == 0 || getHeight() == 0)
return;
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius)
Bitmap sbmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(),
Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xffa19774;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2 + 0.7f,
sbmp.getHeight() / 2 + 0.7f, sbmp.getWidth() / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
如果没有在适配器中使用，上面的代码可以正常工作。
这是我的适配器代码：
public class ListAdapter extends BaseAdapter
Activity activity;
public ArrayList<HashMap<String,String>> list;
public ListAdapter(Activity activity, ArrayList<HashMap<String, String>>list )
super();
this.activity=(Activity)activity;
this.list=list;
public int getCount()
return contactList.size();
public Object getItem(int position)
return contactList.get(position);
public long getItemId(int arg0)
return 0;
private class ViewHolder
ImageView imguser;
public View getView(int position, View convertView, ViewGroup parent)
ViewHolder holder;
LayoutInflater inflater = activity.getLayoutInflater();
if (convertView == null)
convertView = inflater.inflate(R.layout.ads, null);
holder = new ViewHolder();
holder.imguser=(ImageView)convertView.findViewById(R.id.imguser);
convertView.setTag(holder);
else
holder = (ViewHolder) convertView.getTag();
HashMap<String, String> item = contactList.get(position);
imageLoader.displayImage("http://192.168.1.35/test/usersPic/"+item.get("profileImg"), holder.imguser,
options, imageListener);
return convertView;
这是我得到的错误：

你能帮我解决这个问题吗？
【问题讨论】：
同时发布您的 xml 代码 你在你的 xml 代码中使用 com.tejarat.example.RoundedImageView 作为 ImageView 标签吗？如果是这样，用你的包名替换 'com.tejarat.example'（如果这不是你的包名）。 @KarthikaPB 是的，这是我的包名 【参考方案1】：刷新您的项目，然后检查您的 xml 中的自定义 roundimageview 是否在您单击它时将您重定向到您的类文件。
【讨论】：
【参考方案2】：在你的getView()方法改行：
holder.imguser=(ImageView)convertView.findViewById(R.id.imguser);
用这个：
holder.imguser=(RoundedImageView)convertView.findViewById(R.id.imguser);
可能还有其他问题，但这个问题目前是可见的。
【讨论】：
没用，我以前用过它作为imageView，它确实有效。 在你的xml中，你必须用com.tejarat.example.RoundedImageView替换ImageView标签，你还必须在java中使用RoundedImageView。但是很难假设那里出了什么问题。实际上，您需要替换适配器中的所有 ImageView。否则将无法执行
我已经这样做了，我已经在我的 xml 代码中定义了 com.tejarat.example.RoundedImageView。
你是不是把CustomAdapter中的所有imageView都换成了RoundedImageView？【参考方案3】：
请在您的适配器中检查传递参数：
imageLoader.displayImage("http://192.168.1.35/test/usersPic/"+item.get("profileImg"), holder.imguser,
options, imageListener);
选项??
你有没有初始化选项值。 请检查。
【讨论】：
【参考方案4】：如果你只使用包含
mOptions = new DisplayImageOptions.Builder()
.cacheOnDisc(true)
.cacheInMemory(true)
.showImageForEmptyUri(R.drawable.noimage_round)
.showImageOnFail(R.drawable.noimage_round)
.bitmapConfig(Bitmap.Config.RGB_565)
.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
.considerExifParams(true)
.displayer(new RoundedBitmapDisplayer(context.getResources().getDimensionPixelSize(R.dimen.adapter_main_width)))
.build();
和
mImageLoader.displayImage(searchImage, holder.sThumb, mOptions);
将创建圆形图像
