我试过了:
rounded_textfield.xml:
public static class VisualTreeExtensions
{
public static T GetVisualParentOfType<T>(this DependencyObject child)
where T : DependencyObject
{
if (child is T)
return child as T;
var parentObject = VisualTreeHelper.GetParent(child);
if (parentObject == null) return null;
var parent = parentObject as T;
return parent ?? GetVisualParentOfType<T>(parentObject);
}
public static T GetChildOfType<T>(this DependencyObject depObj)
where T : DependencyObject
{
if (depObj == null) return null;
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
{
var child = VisualTreeHelper.GetChild(depObj, i);
var result = (child as T) ?? GetChildOfType<T>(child);
if (result != null) return result;
}
return null;
}
}
activity.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#EEEEEE"/>
<corners
android:bottomRightRadius="8dp"
android:bottomLeftRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp"/>
</shape>
在编辑器中它是灰色的,但在手机上它是白色的。

您的代码是正确的,只需清理项目即可。有一件事你应该记住,根据不同的设备显示设置和显示屏幕,不同颜色的颜色会有所不同。

创建一个名为custom_edit_text.xml的文件,并将其放在项目res文件夹的xml文件夹中。
将以下代码粘贴在那里:
dispatch_semaphore_wait(dataSemaphore, DISPATCH_TIME_FOREVER)
现在只需在您的activty_main.xml文件中引用此xml,如下所示:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="#ffffff" />
<stroke android:width="1dip" android:color="#ffffff"/>
</shape>
干杯!
