Three small issues encountered in Android development

Several issues noted in Android development

1, about Actionbar

Initializing the configuration Actionbar,getactionbar is often null because the full-screen display is set in the source or layout file, so there is no problem with setting the full screen.

2, about TextView

TextView default is no focus, so there is no click event, and can not directly implement the background of the selector. By setting android:clickable = true; Yes, that's a lot different from button.

3, about the PHP code in Sourcinsight.

Sourcinsight does not support PHP code by default, so the import is useless. The key is to set the file filter in the C project by the following setting of *. * To browse PHP type files normally.
