control.Android also offers some of the more powerful data types, such as Sparsearray, Sparsebooleanarray, Sparseintarray, and Pair.The data structure of the sparse series is a special process for the case of the key int, using binary lookup and simple array storage, plus the overhead of not requiring a generic conversion, and better performance than the map. But I don't quite understand why the default capacity size is 10, is it statistical, or now memory optimization does not need to consider
In fact, this Android computer, all the backstage ideas and "C # calculator Code" is exactly the same. The Win form program is ported to Android, from C # to Java in fact, because the basic syntax is very similar, the only difficulty is the Android XML layout part, unlike C # forms can be directly dragged.Or a calculat

The barcode originated with the the 1940s, later in 1970 the UPC code was invented and began to be widely used with food packaging.
The specific introduction can look at Baidu encyclopedia one dimensional code.
The two-dimensional code is essentially similar to a one-

The Ontouchevent event method is also used in the above code. The dismiss method is called in the method to close the dialog box. The reader can run an example of this article to see if you can close the dialog box and suspend activity by clicking
The Android source code directory hardware/ril/libril contains a total of five C/CPP files: ril_commands.h, ril_unsol_commands.h, ril_event.h, ril_event.cpp, and ril. cpp. This article mainly analyzes the ril. cpp file.We can divide the file into the definition part and the implementation part. Let's look at the definition part first:[Cpp]# Define LOG_TAG "RILC"# Include # Include # Include # Include # Incl

Since learning box2d for a period of time, I have a preliminary understanding. I wanted to do a simple game exercise, but I was too busy (and too lazy) to continue. Share the code now. Don't spray it, don't hit it! For more information, see.

This is the layout that initializes a drop-down refresh and calls Setcontentview to set to the activity.
After the Drop-down refresh is complete, we can call the Onpulldownrefreshcomplete () and Onpulluprefreshcomplete () methods to stop the refr
