This article illustrates how Android takes pictures from the system gallery. Share to everyone for your reference. Specifically as follows: In your own application, take pictures from the system gallery and intercept them, and then return to your application. This is a lot of information about the application needs of the image function. Write an example, come up with a big button, even the layout is not. Finally, select a part of the

This article describes the Android implementation of custom with text and Picture button methods. Share to everyone for your reference. The specific analysis is as follows: In Android development, it's often necessary to use a button with text and pictures to explain the common implementations.

The size of the image in android = The total number of images * Each image occupies the size.Android saves picture pixel information using ARGB, meaning that each pixel occupies 4 bytes.For images with a resolution of 2400*3200, loading to Android requires 2400*3200*4=30720000 bytes, requires 30000Kb, requires 29.30MbThe image of this resolution is loaded directl
