// Question: decompose a positive integer into a prime factor. For example, enter 90 and print 90 = 2*3*3*5.// Program analysis: to decompose the prime factor of N, you should first find a minimum prime number k, and then follow the steps below to complete:// (1) if the prime number is equal to N, it indicates that the process of decomposing the prime factor is over. Print it out.// (

If the navigation bar is applied and most of the activity's bottom navigation bar is the same, the navigation bar can be written as a generic module.4) ListView. Most applications use the ListView to show multiple data. The ListView style may often be adjusted later in the project, so it is better to use the ListView as a common module.

Next, we will continue to learn about other IOs controls. The controls used this time include slider, and of course there are some labels that have been used before. We will not create a new project this time. Of course, if you want to create a new project, you can use the previous project control fun. As shown in the last articleWe added an imageview, two labels, and two textfields. Now we continue to add other controls. 1) Add slider and labelSlider is similar to a slider. It slides between th
