【汇总】Android 常用方法整理

1.解决ActionBar OverFlow按钮不显示。(在oncreate中调用即可)

private void setOverflowShowingAlways() { try { ViewConfiguration config = ViewConfiguration.get(this); Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey"); menuKeyField.setAccessible(true); menuKeyField.setBoolean(config, false); } catch (Exception e) { e.printStackTrace(); } }

2.解决ActionBar Overflow中的按钮只有title没有图片的方法。(重写onMenuOpend方法)

@Override public boolean onMenuOpened(int featureId, Menu menu) { if (featureId == Window.FEATURE_ACTION_BAR && menu != null) { if (menu.getClass().getSimpleName().equals("MenuBuilder")) { try { Method m = menu.getClass().getDeclaredMethod("setOptionalIconsVisible", Boolean.TYPE); m.setAccessible(true); m.invoke(menu, true); } catch (Exception e) { } } } return super.onMenuOpened(featureId, menu); }
