android中的对话框位置
我正在创建一个商店地图，其中图像来自服务器。我有产品项目具体位置的坐标。我在画布上绘制的不同标记上显示对话框。 当我在makers上单击时，对话框显示得非常完美，但当我滚动图像并再次单击标记时，对话框位置也会每次更改。是否有任何解决方案可以完美定位图像滚动条上的对话框？ 多谢各位 main.xmlandroid中的对话框位置,android,Android,我正在创建一个商店地图，其中图像来自服务器。我有产品项目具体位置的坐标。我在画布上绘制的不同标记上显示对话框。 当我在makers上单击时，对话框显示得非常完美，但当我滚动图像并再次单击标记时，对话框位置也会每次更改。是否有任何解决方案可以完美定位图像滚动条上的对话框？ 多谢各位 main.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http

对于（int i=0；i请尝试在屏幕底部显示此对话框：
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;

设置属性（wlp）；
如果您需要，此代码还可以防止android将对话框的背景调暗。您应该能够更改重力参数以将对话框移动约尝试将对话框的定位点设置为您的标记。Google maps还使用定位点显示标记的标记窗口
这里有一个锚定的方法
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);
希望对你有帮助你需要详细说明这个问题。上面的解释毫无意义。
