android-如何具有可点击和可检查的textview [英] android - how to have a clickable AND checkable textview
问题描述
我想要以下内容:一个文本视图.)单击时更改其背景.)保持背景,直到再次单击为止.
I want to have the following: a textview that .)changes its background when clicked .)maintains that background until it is clicked again
所有这些都归结为可检查"状态,但是我无法弄清楚它是如何工作的.这是我用于背景的xml:
it all comes down to the "checkable" state, but i couldnt figure out how this exactly works. here is the xml i am using for background:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- pressed -->
<item android:drawable="@drawable/menuselected"
android:state_pressed="true" />
<!-- checked -->
<item android:drawable="@drawable/menuselected"
android:state_checked="true" />
<!-- default -->
<item android:drawable="@drawable/transpixel"/>
</selector>
更新:现在部分起作用.我采用了 http://kmansoft.com/2011/01的大部分代码/11/checkable-image-button/用于我的自定义Textview.我实际上是这样做的,我也需要单选按钮的功能.现在,我可以检查Textview,但不能取消选中它.有人知道为什么会这样吗?
Update: it partly works now. I adopted most of the code from http://kmansoft.com/2011/01/11/checkable-image-button/ for my custom Textview. I did this as actually, I need the functionality of a radio button as well. Now I can check a Textview, but I cant uncheck it. Does anybody see why that could be the case?
推荐答案
您可以将CheckedTextView与checkMark null和为您的可选背景
You can use CheckedTextView with checkMark null and background your selectable
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checkMark="@null"
android:background="@drawable/selectable"/>
您可以选择
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@drawable/selector" />
</selector>
