这里用了一个回调方法, 对外提供, 不用过多解释, 主要说一下要实现圆角, 最主要的是MyDialogStyle这个文件, 在加一个圆角的背景, 看看里面的实现:

res/values/styles.xml

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><style <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"MyDialogStyle"</span> parent=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"@android:style/Theme.Dialog"</span>>     <!<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">--背景透明--></span>     <<span class="hljs-property" style="box-sizing: border-box;">item</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"android:windowBackground"</span>>@android:color/transparent</<span class="hljs-property" style="box-sizing: border-box;">item</span>>     <!<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">--没有标题头--></span>     <<span class="hljs-property" style="box-sizing: border-box;">item</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"android:windowNoTitle"</span>><span class="hljs-constant" style="box-sizing: border-box;">true</span></<span class="hljs-property" style="box-sizing: border-box;">item</span>>     <!<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">-- 是否允许背景灰暗 --></span>     <<span class="hljs-property" style="box-sizing: border-box;">item</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"android:backgroundDimEnabled"</span>><span class="hljs-constant" style="box-sizing: border-box;">true</span></<span class="hljs-property" style="box-sizing: border-box;">item</span>></style></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul>

我试的时候只需要上面两个属性就行了, android:backgroundDimEnabled 默认是true, 如果设置成false弹出dialog的时候就背景就会不变暗!

具体用法可以在点击方法中如下调用:

实现的效果如下:

ps: 希望自己能坚持下去!

自己也第一次使用Git上传项目源码到github, 中间也遇到一些问题, 准备在下一篇文章中总结出来 !
