Learn Android intermediate

I haven't been writing a blog for a while. Recently, the reading volume has increased and the workload has also increased. In addition, the network is poor. Alas, I can only write it at this time.

Now I am learning to enter the Android intermediate level. The mind map I have drawn has opened a small flower, but I will forget some knowledge points. Summarized some intermediate knowledge points:

The first is ListView. This is a very important control that will be frequently used in the future. The control is only a combination control and an adapter must be set. Now it is only a BaseAdapter and only getView () is known () and getCount () are useful. Three methods to optimize data are learned in getView.

Then there is the knowledge of processes and threads, the communication between processes and the priority of processes, and the ANR dialog box for Activity time-consuming operations in multithreading. Three methods are used to solve the problem. I learned asynchronous loading last week, that is, inheriting the AsyncTask class to solve the time-consuming operations of the Activity.

Finally, I learned the res resource file today, with three tags, themes and styles, internationalization methods, fragmentation, and other knowledge points. I have never touched any Android knowledge I learned during my college years, although unfamiliar, it is easy to learn. This knowledge is not difficult, but not flexible enough. It is a bit confusing to use in today's homework and can be used in future projects, it is very important for future studies.
