我正在尝试将标准的浅灰色更改为浅绿色。似乎没有简单的方法可以做到这一点(例如，通过Android Themes)，但是我发现了一种解决方法，如本页所述:http://tinyurl.com/342dgn3。

作者似乎不见了，有人可以帮我集成这段代码吗？我不明白在哪里需要实现LayoutInflater工厂类。

最佳答案

当您充气菜单时，请调用此setMenuBackground()方法

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater inflater=getMenuInflater();
    inflater.inflate(R.menu.menu,menu);
    setMenuBackground();
    return true;
}

并将其写在setMenuBackground()方法中

    protected void setMenuBackground(){
        // Log.d(TAG, "Enterting setMenuBackGround");
        getLayoutInflater().setFactory( new Factory() {
            public View onCreateView(String name, Context context, AttributeSet attrs) {
                if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {
                    try { // Ask our inflater to create the view
                        LayoutInflater f = getLayoutInflater();
                        final View view = f.createView( name, null, attrs );
                        /* The background gets refreshed each time a new item is added the options menu.
                        * So each time Android applies the default background we need to set our own
                        * background. This is done using a thread giving the background change as runnable
                        * object */
                        new Handler().post( new Runnable() {
                            public void run () {
                                // sets the background color
                                view.setBackgroundResource( R.color.androidcolor);
                                // sets the text color
                                ((TextView) view).setTextColor(Color.BLACK);
                                // sets the text size
                                ((TextView) view).setTextSize(18);
                }
                        } );
                    return view;
                }
            catch ( InflateException e ) {}
            catch ( ClassNotFoundException e ) {}
        }
        return null;
    }});
}
