Question

我的应用程序中有一些imageView，其中一个imageview是父图像，父图像的功能是来自另一个imageview孩子的显示图像，如果点击的话。

enter image description here

如果图像B1单击，那么ImageView B1的源图像显示在imageView A中，另一个imageView B可以像B1一样点击，我是如何实现的？

i使用此代码在imageview B中显示图像。

private class CustomInfoWindowAdapter implements InfoWindowAdapter{

        private View view;

        public CustomInfoWindowAdapter() {
            view = getLayoutInflater().inflate(R.layout.custom_info_window,
                    null);
        }

        @Override
        public View getInfoContents(Marker marker) {

            if (MapV2InfoWindow.this.marker != null
                    && MapV2InfoWindow.this.marker.isInfoWindowShown()) {
                MapV2InfoWindow.this.marker.hideInfoWindow();
                MapV2InfoWindow.this.marker.showInfoWindow();
            }
            return null;
        }

        @Override
        public View getInfoWindow(final Marker marker) { 
            MapV2InfoWindow.this.marker = marker;

            String url = null;

            if (marker.getId() != null && markers != null && markers.size() > 0) {
                if ( markers.get(marker.getId()) != null &&
                        markers.get(marker.getId()) != null) {
                    url = markers.get(marker.getId());
                }
            }
            final ImageView image = ((ImageView) view.findViewById(R.id.badge));

            if (url != null && !url.equalsIgnoreCase("null")
                    && !url.equalsIgnoreCase("")) {
                imageLoader.displayImage(url, image, options,
                        new SimpleImageLoadingListener() {
                            @Override
                            public void onLoadingComplete(String imageUri,
                                    View view, Bitmap loadedImage) {
                                super.onLoadingComplete(imageUri, view,
                                        loadedImage);
                                getInfoContents(marker);
                            }
                        });
            } else {
                image.setImageResource(R.drawable.ic_launcher);
            }


            return view;
        }
}

感谢。

Answer 1

就这样做。

imageViewA.setImageDrawable( imageViewB.getDrawable() );

Answer 2

为您的活动实施onClick并在 onClick 监听器上执行以下操作：

switch (key) {
        case R.id.b1:
            Bitmap bitmap = ((BitmapDrawable)imageViewB1.getDrawable()).getBitmap();
imageViewA.setImageBitmap(bitmap);
            break;

        case R.id.b2:
            Bitmap bitmap = ((BitmapDrawable)imageViewB2.getDrawable()).getBitmap();
imageViewA.setImageBitmap(bitmap);
            break;

        case R.id.b3:
            Bitmap bitmap = ((BitmapDrawable)imageViewB3.getDrawable()).getBitmap();
imageViewA.setImageBitmap(bitmap);
            break;

        default:
            break;
        }

Answer 3

点击ImageViewb1时输入此代码。

Bitmap bitmap = ((BitmapDrawable) mImageView.getDrawable()).getBitmap();
imageViewA.setImageBitmap(bitmap);

重复以上代码，点击B2和B3。

android：从另一个imageview源在imageview中显示图像？
