Question

我需要在新活动中点击放大图像我从服务器下载这些图像，然后以编程方式将它们添加到主视图中，从而明确地设置它们的ID。但我的问题是它只是选择最后一个图像的id，因此给出了异常。我在它获取图像的活动中使用以下代码。：

        private OnClickListener clickImageListener = new OnClickListener() {
             public void onClick(View v) {
        Intent fullScreenIntent = new Intent(v.getContext(),FullImageActivity.class);

            fullScreenIntent.putExtra(ProfilePageNormalUser.class.getName(),imageId) ;
            ProfilePageNormalUser.this.startActivity(fullScreenIntent); 
            System.out.println("going to fullimageactivity");

    }
};

以及要放大图像的以下代码。

       Intent intent = getIntent();
        int imageId = (Integer) intent.getExtras().get(ProfilePageNormalUser.class.getName());
        imageView.setLayoutParams( new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));
        InputStream is = this.getResources().openRawResource(imageId);
        Bitmap originalBitmap = BitmapFactory.decodeStream(is);
        ImageView myimage = (ImageView) findViewById(R.id.imageviewEnlarged);
        myimage.setImageBitmap(originalBitmap);
        myimage.setScaleType(ScaleType.FIT_XY);

但它给了我以下例外：

编辑：它也在堆栈跟踪中给出了以下异常：

Answer 1

我只能猜测而不会看到堆栈跟踪

findViewById(R.id.imageviewEnlarged);// maybe here?...

我是Android的新手，但例外情况是告诉你ViewGroup$LayoutParams不会去你所在的位置，或者你试图把那些不会去那里的东西

Answer 2

我认为你的问题在于ResourceNotFoundException。这是堆栈跟踪中的行：

11-01 10:25:51.323: ERROR/AndroidRuntime(5001): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x4

确保您在此行中获取正确的图片ID：

int imageId = (Integer) intent.getExtras().get(ProfilePageNormalUser.class.getName());

Android：在新活动中放大图像大小会引发异常：android.content.res.Resources $ NotFoundException：Resource ID＃0x4
