单击设备菜单按钮后,如何更改底部显示的菜单项的背景
我正在使用ActionBarSherlock,顶部的 ActionBar 有蓝色背景。以为底部菜单的背景也是如此。但它是白色的。看起来像默认值。所以,这个图标在那个白色背景上看起来不太好。我怎样才能将其更改为蓝色。
我试过这个:
<item name="android:panelBackground">@drawable/blue</item>
但是没有用。
谢谢你。

我有类似的要求,我找到了这个可行的解决方案。使用以下
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
addOptionsMenuHackerInflaterFactory();
return true;
}
@SuppressWarnings("rawtypes")
static Class IconMenuItemView_class = null;
@SuppressWarnings("rawtypes")
static Constructor IconMenuItemView_constructor = null;
// standard signature of constructor expected by inflater of all View classes
@SuppressWarnings("rawtypes")
private static final Class[] standard_inflater_constructor_signature =
new Class[] { Context.class, AttributeSet.class };
protected void addOptionsMenuHackerInflaterFactory()
{
final LayoutInflater infl = getLayoutInflater();
infl.setFactory(new Factory()
{
public View onCreateView(final String name,
final Context context,
final AttributeSet attrs)
{
if (!name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView"))
return null; // use normal inflater
View view = null;
if (IconMenuItemView_class == null)
{
try
{
IconMenuItemView_class = getClassLoader().loadClass(name);
}
catch (ClassNotFoundException e)
{
// this OS does not have IconMenuItemView - fail gracefully
return null; // hack failed: use normal inflater
}
}
if (IconMenuItemView_class == null)
return null; // hack failed: use normal inflater
if (IconMenuItemView_constructor == null)
{
try
{
IconMenuItemView_constructor =
IconMenuItemView_class.getConstructor(standard_inflater_constructor_signature);
}
catch (SecurityException e)
{
return null; // hack failed: use normal inflater
}
catch (NoSuchMethodException e)
{
return null; // hack failed: use normal inflater
}
}
if (IconMenuItemView_constructor == null)
return null; // hack failed: use normal inflater
try
{
Object[] args = new Object[] { context, attrs };
view = (View)(IconMenuItemView_constructor.newInstance(args));
}
catch (IllegalArgumentException e)
{
return null; // hack failed: use normal inflater
}
catch (InstantiationException e)
{
return null; // hack failed: use normal inflater
}
catch (IllegalAccessException e)
{
return null; // hack failed: use normal inflater
}
catch (InvocationTargetException e)
{
return null; // hack failed: use normal inflater
}
if (null == view) // in theory handled above, but be safe...
return null; // hack failed: use normal inflater
// apply our own View settings after we get back to runloop
// - android will overwrite almost any setting we make now
final View v = view;
new Handler().post(new Runnable()
{
public void run()
{
v.setBackgroundDrawable(getResources().getDrawable(R.drawable.menubuttonselector));
// here use your own selector drawable
try
{
// in Android <= 3.2, IconMenuItemView implemented with TextView
// guard against possible future change in implementation
TextView tv = (TextView)v;
tv.setTextColor(Color.WHITE);
}
catch (ClassCastException e)
{
// hack failed: do not set TextView attributes
}
}
});
return view;
}
});
}
警告:
这是一个黑客解决方案。因为我需要它,一旦我无法给出足够的时间来确定是否有任何副作用。但它完美地为我服务。希望对你有帮助
