在Android的自定义开关部件4 [英] Custom switch widget in Android 4

问题描述

我越来越疯狂与开关按钮的Andr​​oid 4.0。

I am getting crazy with switch buttons in Android 4.

首先，我设置了一个选择作为背景与绘制文件夹中选择两个不同的PNG文件：

First of all, I have set a selector as background with two different PNG files selected from drawable folder:

<?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>

但我不知道为什么他们的x缩放。我要管理这种规模，但我试图改变layout_width /身高/体重...没有更迭。

but I don't know why they are x-scaled. I want to manage this size, but I have tried to change layout_width/height/weight... without succes.

我还用作开关的拇指定制PNG文件。我还需要管理这个拇指大小，因为如果我设置纹元和textOff propieties为，拇指得到一个非常小的尺寸。此外，我想改变的拇指垫有关的背景，因为它不居中显示。

I have also a custom PNG file to be used as the thumb of the switch. 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. Moreover, I would like to change thumb padding in respect of the background, because It does not appears centered.

下面是我的交换机XML定义：

Here is my Switch XML definition:

<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" />

我曾试图改变图像大小，使他们九补丁的，但我不能达到我的目标。

I have tried to change image sizes and making them nine-patch ones, but I can't reach my target.

任何帮助将AP preciated。谢谢！

Any help will be appreciated. Thank you!

推荐答案

在solucion为非常小的滑块没有文字被解决了的组合：

The solucion for the extremely small slider with no text was solved with a combination of:

android:thumbTextPadding="25dp"
android:textOn=""
android:textOff=""

然后，将小填充在同一拉头的问题是一个9补丁图像的问题。我不得不延长底部和右侧的黑色线条多了一个像素simetrically。

Then, the problem of the small padding in the same slider was a 9-patch image problem. I had to extend bottom and right black lines one more pixel simetrically.

希望这可以帮助别人同样的问题。
