blocks|key|125103|text|创建一个名称类似于txt_bg.xml的xml|type|unstyled|depth|inlineStyleRanges|entityRanges|data|125104|<?xml+version="1.0"+encoding="utf-8"?>

create a xml with name something like txt_bg.xml

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;

 &lt;item android:drawable="@drawable/numpad_button_bg_selected" android:state_selected="true"&gt;&lt;/item&gt;
 &lt;item android:drawable="@drawable/numpad_button_bg_pressed" android:state_pressed="true"&gt;&lt;/item&gt;
 &lt;item android:drawable="@drawable/numpad_button_bg_normal"&gt;&lt;/item&gt;

&lt;/selector&gt;
</code></pre>

then add in texview xml 

<pre><code>android:background="@drawable/txt_bg"
android:clickable="true"
</code></pre>

hope it will help.

嗨，我是android开发的新手。我想创建onclick效果到文本视图。当我点击文本视图时，它会闪烁或产生一些特效。我试过换颜色，但它不起作用。如何在textview onclick上做闪烁效果?？请帮助我与示例代码。提前感谢:)
