SDK5.0 的Hierarchy view使用方法

由 此生再无相见时 提交于 2020-12-06 11:51:16
Android做维护开发的时候，Hierarchy view是非常好用的界面分析工具，对于 不是自己开发的界面，可以很方便的查看到view的id，以定位view的相关 代码 。 但是似乎是Android4.0之后，原先在tool目录的启动方式不能用了，硬要让人使用Android device monitor(ADM)。 打开了ADM之后，像原先一样的点击device工具栏的Hierarchy 图标，发现获取出来的view不能查看id。。 不能查看id我还要它干毛。。。。 放弃了好一段时间后，还是觉得没有它维护太麻烦。 再次打开ADM，研究了一番，终于： 在菜单栏的Window，选择 open perspective，弹出的界面选择 Hierarchy view . 整个世界都美好了。。。 ====================================== 不过在ADM里启动好像执行慢了很多，会卡顿。 一个工具就该做一件事，把一堆工具放到一起炖大杂烩，这感觉~Google大概是脑子坏了。。。 来源： oschina 链接： https://my.oschina.net/u/947746/blog/413659

Resizing a bitmap to a fixed value but without changing the aspect ratio

由 本秂侑毒 提交于 2020-11-30 05:10:41
问题 I'm looking for a solution for the following problem: how to change the size of a Bitmap to a fixed size (for example 512x128). The aspect ratio of the bitmap content must be preserved. I think it should be something like this: create an empty 512x128 bitmap scale the original bitmap down to fit the 512x128 pixels with keeping the aspect ratio copy the scaled into the empty bitmap (centered) What is the simplest way to achieve this? The reason for all this is, that the GridView messes the
