Questions about moving focus to the ListView in Android

A solution

This is not a fundamental solution: write a new class, Inherit the ListView, and overwrite the onfocuschanged.

@Override protected void Onfocuschanged (Boolean gainfocus, int direction, Rect previouslyfocusedrect) { Super.onfocuschanged (Gainfocus, direction, previouslyfocusedrect); if (gainfocus && previouslyfocusedrect! = null) {Final ListAdapter adapter = Getadapter (); final int count = ADAP Ter.getcount (); switch (direction) {case focus_down:for (int i = 0; i < count; i++) {if (!adapter.isenabled (i)) {continue;} SetSel Ection (i); Break } break; Case focus_up:for (int i = count-1; i>=0; i--) {if (!adapter.isenabled (i)) {continue;} setselection (i); break;} BR Eak Default:break; } } }

Here, I only deal with Focus_down and focus_up. Due to the inability to access the mfirstposition, the processing has also been simplified: when the focus is removed from above, select the first one to select, and the last one to select when moving from below.
