问题 I need some help with design for multiple screen sizes in Android. I created layout, layout-sw600dp, values, and values-sw600dp with dimens.xml file with dimension for layout-sw600dp. But when I run application in emulator with 7" tablet, the design is not set up properly. How I can fix this? 回答1: The fundamental size of a screen, as indicated by the shortest dimension of the available screen area. Specifically, the device's smallestWidth is the shortest of the screen's available height and

问题 Refer to the question How to Convert two 8 bit represented byte to single 16 bit represented integer value in Android. I got an answer like this short yourinteger16 = (short)(((bytes[0] & 0xFF) << 8) | (bytes[1] & 0xFF)); This answer is correct for the positive number. But in the case of the negative number, it's failing. For example, I am sending the value from the BLE to the application as -10. The value will convert from the BLE as -10000 because of mAh/mV conversion of current and voltage
