Question

我正在创建一个商店地图，其中图像来自服务器。我有产品项目的具体位置的协调。我正在通过画布绘制的不同标记上显示对话框。当我点击制作者时，对话框显示完美，但是当我滚动图像和放大时再次单击标记，对话框位置也会每次更改。有没有解决方案在图像滚动上完美定位对话框？谢谢。

Answer 1

尝试此操作以在屏幕底部显示对话框：

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

此代码还可以防止android在需要时调暗对话框的背景。您应该能够更改重力参数以移动关于

的对话框

Answer 2

尝试将对话框的锚点设置为您的标记.Google地图也使用锚点显示标记的标记窗口。

这是设置锚点的方法。

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.LEFT_OF, R.id.id_to_be_left_of);

button.setLayoutParams(params);
