如何为地图图像添加缩放控件和垂直和水平滚动。我已将图像作为背景放在屏幕上..请注意如何编码

Answer 1

您可能需要将图像放在ImageView中才能进行缩放。然后在代码中执行此操作：

/* Set up the Zoom controls */
ImageView iview = (ImageView)findViewById(android.R.id.imageViewId);
FrameLayout mContentView = (FrameLayout) getWindow().getDecorView().findViewById(android.R.id.content);

final View zoom = iview.getZoomControls();
mContentView.addView(zoom, ZOOM_PARAMS);
zoom.setVisibility(View.VISIBLE);
