[英]Custom switch widget in Android 4
I am getting crazy with switch buttons in Android 4. 我对Android 4中的切换按钮感到疯狂。
First of all, I have set a selector as background with two different PNG files selected from drawable folder: 首先,我设置了一个选择器作为背景,从drawable文件夹中选择了两个不同的PNG文件:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/form_switch_no" android:state_checked="false"/>
<item android:drawable="@drawable/form_switch_ok" android:state_checked="true"/>
<item android:drawable="@drawable/form_switch_no"/>
</selector>
but I don't know why they are x-scaled. 但我不知道为什么他们是x-scaled。 I want to manage this size, but I have tried to change layout_width/height/weight... without succes. 我想管理这个大小,但我试图改变layout_width / height / weight ...没有成功。
I have also a custom PNG file to be used as the thumb of the switch. 我还有一个自定义PNG文件用作交换机的拇指。 I also need to manage the size of this thumb, because if I set textOn and textOff propieties as "", thumb gets a very small size. 我还需要管理这个拇指的大小,因为如果我将textOn和textOff propments设置为“”,拇指的大小就会非常小。 Moreover, I would like to change thumb padding in respect of the background, because It does not appears centered. 此外,我想改变背景的拇指填充,因为它不会出现居中。
Here is my Switch XML definition: 这是我的Switch XML定义:
<Switch
android:id="@+id/switchUsers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/user"
android:textOn=""
android:textOff=""
android:thumb="@drawable/form_switch_slider"
android:track="@drawable/switch_user_selector" />
I have tried to change image sizes and making them nine-patch ones, but I can't reach my target. 我试图改变图像大小并使它们成为九个补丁,但我无法达到目标。
Any help will be appreciated. 任何帮助将不胜感激。 Thank you! 谢谢!
The solucion for the extremely small slider with no text was solved with a combination of: 没有文字的极小滑块的解决方案通过以下组合解决:
android:thumbTextPadding="25dp"
android:textOn=""
android:textOff=""
Then, the problem of the small padding in the same slider was a 9-patch image problem. 然后,同一滑块中的小填充问题是9补丁图像问题。 I had to extend bottom and right black lines one more pixel simetrically. 我不得不在底部和右边的黑色线上再增加一个像素。
Hope this helps someone with the same problem. 希望这可以帮助有同样问题的人。
