Create a custom notification Layout By default, the notification displayed in the notification window includes the title and message text. The two items are defined using the contenttitle and contenttext parameters of the setlatesteventinfo () method. However, you can also use the remoteviews class to define a custom Layout for notifications. 3 is an example of custom notification layout. It looks similar to the default notification, but it is actuall

this qualifier? If no, the system returns Step 1 and continues to compare the next qualifier (in this example, the system returns to "no" until the language qualifier is compared "). If "yes" is returned, proceed to step 4. 4. Remove the directories whose names do not contain this qualifier. In this example, the system will exclude all directories that do not contain the language qualifier: Drawable/ Drawa

navigation As another internal navigation (or filtering) mode of the activity, the Operation Bar provides a built-in drop-down list. The drop-down list provides different sorting modes for the content in the activity. The basic process for enabling drop-down navigation is as follows: 1. Create a list of optional projects for the drop-down list and the layout used to describe the projects; 2. Implement the actionbar. onnavigationlistener callback, which defines the behavior that occurs when the

I have been in touch with Linux for several years. I feel that Linux has been separated by minutes and is full of regrets. One of the biggest regrets is that I have never been proficient in Vim, it cannot fully adapt to Code development under vim. I think it is necessary to summarize the use of VIM in my recent work. however, I cannot describe how to use all Vim commands. Instead, I think it is more effective to describe the operation commands commonly used for editing
