Open-sided Android stroke?

由 三世轮回 提交于 2019-11-26 08:49:36
问题 Is it possible to create an Android shape object with stroke on only certain sides? Eg I have: <stroke android:width=\"3dip\" android:color=\"#000000\" android:dashWidth=\"10dip\" android:dashGap=\"6dip\" /> Which is similar to this CSS: border: 3px dashed black; How can I set the stroke on just one side? This is how I would do it in CSS: border-left: 3px dashed black; How do you do this in Android XML? 回答1: I achieved a good solution with this one: <?xml version="1.0" encoding="utf-8"?>

问题 I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center. Does anyone know how to get it right? the stroke needs to be the bottom line/border. I am using the shape as a background to a TextView. Please, never mind why I need it. <?xml version=\"1.0\" encoding=\"utf-8\"?> <layer-list xmlns:android=\"http://schemas.android.com/apk/res/android\" > <item> <shape android:shape=\"rectangle\"

I have one ImageView and set a drawable on it. Now I need to get the ID of the drawable on click event of ImageView dynamically. How can I get it? imgtopcolor = (ImageView) findViewById(R.id.topcolor); imgtopcolor.setImageResource(R.drawable.dr); // How do I get this back?

android:drawableLeft margin and/or padding

由 时光总嘲笑我的痴心妄想 提交于 2019-11-26 07:54:07
问题 Is it possible to set the margin or padding for the image which we added with the android:drawableLeft ? 回答1: As cephus mentioned android:drawablePadding will only force padding between the text and the drawable if the button is small enough. When laying out larger buttons you can use android:drawablePadding in conjunction with android:paddingLeft and android:paddingRight to force the text and drawable inward towards the center of the button. By adjusting the left and right padding separately

Vertical line using XML drawable

由 為{幸葍}努か 提交于 2019-11-26 06:56:07
问题 I\'m trying to figure out how to define a vertical line (1dp thick) to be used as a drawable. To make a horizontal one, it\'s pretty straightforward: <shape xmlns:android=\"http://schemas.android.com/apk/res/android\" android:shape=\"line\"> <stroke android:width=\"1dp\" android:color=\"#0000FF\"/> <size android:height=\"50dp\" /> </shape> The question is, how to make this line vertical? Yes, there are workarounds, such as drawing a rectangle shape 1px thick, but that complicates the drawable

由 ☆樱花仙子☆ 提交于 2019-11-26 04:29:02
问题 I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files. Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc. 回答1: This is a simple
