Android app option menu

Posted 2021-01-01 Reboost

Main Activity java

@Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.more, menu); return super.onCreateOptionsMenu(menu); } //此重载旨在使能MENU中的ICON显示（4.0之后显示不了option menu icon） @Override public boolean onMenuOpened(int featureId, Menu menu) { if (menu != null) { if (menu.getClass().getSimpleName().equalsIgnoreCase("MenuBuilder")) { try { Method method = menu.getClass().getDeclaredMethod("setOptionalIconsVisible", Boolean.TYPE); if (method != null) { method.setAccessible(true); method.invoke(menu, true); } } catch (Exception e) { e.printStackTrace(); } } } return super.onMenuOpened(featureId, menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.more_menu1: { 　　　　　　　... } break; case R.id.more_menu2: break; } return super.onOptionsItemSelected(item); }
