Android obtains all pictures, video thumbnails, and album covers on the SD card.Query Images First, query the inherent Android database.

First, IntroductionIn Xamarin development, sometimes we want to do a function, but this feature has already been written in Java, and packaged into a jar file. Then we can just take each other's jar file instead of re-writing the code in C #.More detailed information about the bind jar can be seen in https://developer.xamarin.com/guides/android/advanced_topics/binding-a-java-library/ , this is just the simplest binding.Two, Bind JARNow I want to do a

Imagescaletype (imagescaletype.in_sample_int) or try.imagescaletype ( imagescaletype.exactly) ④ Avoid using Roundedbitmapdisplayer. He will create a new bitmap object in the argb_8888 format; ⑤ use. MemoryCache (New Weakmemorycache ()), do not use. Cacheinmemory (); Someone asked how to load the local picture or something, and then add the pro's answer

To handle a wide range of resolutions and sizes. For images, Android uses DPI as the unit. If you select an image, right-click the image under win and you will see the DPI attribute. The higher the DPI, the finer the image. For a mobile phone or display device, a pixel is a point, so DPI = PPI. In turn, it is often said that the height and height of the phone screen PPI are equivalent to the DPI value taken into account when writing a program. The Ret

get the picture in the asynchronous thread and then update the UI thread through the handler message.Use the Asynctask provided in Android to do this. The specific approach is not introduced here, check the API can be, or Google, Baidu under. This is mostly local caching. 2. Local cache:For picture resources, it's impossible to get apps to download remotely (ListView) every time you get them. This will waste resources, but you can not let all the p

This is often the case in development: there are a number of similar images in the Drawable folder (the similarity here is not only similar to the image name, but also similar), and now you have to select one of them according to the user's operation. For example, in a speech-like development, press and hold the "talk" button can be entered into the user said, then, need to have a picture in real time to record the user speaking volume level (1 to 7), we can
