Question

我正在使用我从Github获得的GestureImageView项目，我的drawable文件夹中有几张图片：page1.jpg，page2.jpg，page3.jpg，....... ..page30.jpg。我有一个名为pagenumber的变量，当我点击一个按钮时，这个变量会递增，alson我想在GestureImageView中加载图像。这是我在Main Class中的代码：

pagenumber++;

GestureImageView view1 = (GestureImageView) findViewById(R.id.image);

String uriPath = "android.resource://"+getPackageName()+"/drawable/page"+String.valueOf(pagenumber);

Uri uri = Uri.parse(uriPath);

view1 .setImageURI(uri);

在GestureImageView.java中，代码为：

@Override
public void setImageURI(Uri mUri) {
    if ("content".equals(mUri.getScheme())) {
        try {
            String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};

            Cursor cur = getContext().getContentResolver().query(mUri, orientationColumn, null, null, null);

            if (cur != null && cur.moveToFirst()) {
                imageOrientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
            }  

            InputStream in = null;

            try {
                in = getContext().getContentResolver().openInputStream(mUri);
                Bitmap bmp = BitmapFactory.decodeStream(in);

                if(imageOrientation != 0) {
                    Matrix m = new Matrix();
                    m.postRotate(imageOrientation);
                    Bitmap rotated = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), m, true);
                    bmp.recycle();
                    setImageDrawable(new BitmapDrawable(getResources(), rotated));
                }
                else {
                    setImageDrawable(new BitmapDrawable(getResources(), bmp));
                }
            }
            finally {
                if(in != null) {
                    in.close();
                }

                if(cur != null) {
                    cur.close();
                }
            }
        }
        catch (Exception e) {
            Log.w("GestureImageView", "Unable to open content: " + mUri, e);
        }
    }
    else {
        setImageDrawable(Drawable.createFromPath(mUri.toString()));
    }

    if (drawable == null) {
        Log.e("GestureImageView", "resolveUri failed on bad bitmap uri: " + mUri);
        // Don't try again.
        mUri = null;
    }
}

我在GestureImageView中有一个空图像，它没有加载。 logcat说无法解码流：java.io.FileNotFoundException：/android.resource：/com.example.tests/drawable/page3：open failed：ENOENT（没有这样的文件或目录）

请帮忙吗？

stackoverflow中的其他人似乎有同样的问题，然后在这里修复：D （我为自己标记了这个问题感到遗憾，然后找到答案......）
