10 recommended articles about repetitive execution

I didn’t notice that listview’s getView would be executed multiple times before. This time, because the layout was more complicated, I went to breakpoint tracking during testing and found that the same piece of data was being executed repeatedly. I thought it was strange, so I searched online. The explanations on the Internet are basically the same, that is, when the ListView is laid out, neither height nor width is fill_parent, resulting in continuous calculation of height and continuous refreshing. Or its parent container is not set to fill_parent. If the layout is too complex, it is unrealistic to adjust everything according to fill_parent. So I thought of another solution, which is to dynamically fix the height. After the program runs, fix the height of the ListView and then initialize the Item information. private void fixedListView(){ listView = (ListView) findViewById(R.id.listview);

php--while/do-while

##Introduction: The meaning of the while statement is very simple. It tells PHP to repeatedly execute the nested loop statement as long as the value of the while expression is TRUE. The value of the expression is checked each time the loop starts, so even if the value changes during the loop statement, the statement will not stop execution until this loop.

8. Time complexity PHP uses arrays to reduce the time complexity of the program

Introduction: Time complexity: Time complexity PHP uses arrays Reduce the time complexity of the program: With the continuous improvement of device hardware configuration, for small and medium-sized applications, the requirements for the space complexity of the algorithm have also been relaxed a lot. However, in today's Web2.0 era, there are higher requirements for the time complexity of applications. What is the time complexity of an algorithm? In summary, it refers to selecting an original operation from the algorithm that can represent the algorithm, and using the number of times the original operation is repeated as the time measurement of the algorithm. There are two factors that affect the time complexity: one is the execution time of the original operation, and the other is the number of executions of the original operation caused by the control structure. It is necessary to reduce the time complexity of the algorithm and reduce
