android - 自定义圆形 imageView 得到错误膨胀答案

【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

标签： android android-listview android-imageview

【解决方案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】：

【解决方案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？

【解决方案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】：

【解决方案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
