The former is press the device's menu hard button to eject, the latter is long press widget pop-up.Option MenuWhen we press the menu's Hardware button, option menu will be triggered to display up to 6 options of the icon menu, if the option is more than 6, the 6th option appears as "More", click to enter the Extended menu.

Dip is the same as DP and is used in the Android/ophone example.This is the most common but also the most difficult to understand the size of units. It is closely related to pixel density, so let's first explain wh

I. Overall frameworkFirst, Google provides an official Android frame chart:Android system architecture consists of 5 parts, namely: Linux Kernel, Android Runtime, Libraries, Application Framework, Applications (e-paper is not good to translate, In fact, this is also a simple computer e-text, the following are the main role of each part:1. Linux KernelAndroid provides core system services

PIX when setting the values of the view's properties Android:layout_width and Android:layout_height. Correspondingly, the screen should use the SP to define the size of the text in order for the text to fit better . B. Do not show specific pixel values in the code of the program.To make the code simple, Android internally uses the PIX to represent the size of the control, but this is based on the current s

The second way is that the layout files are duplicated (although the same parts can be included, but logically there are duplicates), including essentially repetitive code that is handled logically. This approach is generally recommended for larger, different item layouts.Sometimes the combination of demand, can be based on the first way,
