Question

我在google搜索了很多，并在stackoverflow中找到了一个如何使用样式和主题更改文本颜色的链接，但我不知道如何在代码中使用。

<style name="TextAppearance.Widget.IconMenu.Item" parent="@android:style/TextAppearance.Small"> 
        <item name="android:textColor">#ff0000</item> 
    </style>

请给我一些片段以便更好地理解。我知道如何通过使用Factory.In更改menuItem的背景，我们可以找到View对象。是否有任何设施可以获得菜单项。那我们可以改变menuItem的颜色吗？

Answer 1

尝试使用此代码更改背景和文字颜色....

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.my_menu, menu);
    getLayoutInflater().setFactory(new Factory() {
    @Override
    public View onCreateView(String name, Context context,
                    AttributeSet attrs) {
                if (name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {
                try {
                    LayoutInflater f = getLayoutInflater();
                    final View view = f.createView(name, null, attrs);
                    new Handler().post(new Runnable() {
                            public void run() {
                            // set the background drawable
                                view.setBackgroundResource(R.drawable.my_ac_menu_background);

                            // set the text color
                                ((TextView) view).setTextColor(Color.WHITE);
                            }
                        });
                        return view;
                    } catch (InflateException e) {
                    } catch (ClassNotFoundException e) {
                    }
                }
                return null;
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

我使用以下内容。将此方法放在您的活动中，并在onCreateOptionsMenu（菜单菜单）方法中调用它。您可以设置backgroundResource而不是设置颜色...只需键入view.setbackground并通过自动完成查看可能性;）

/*
 * IconMenuItemView is the class that creates and controls the options menu
 * which is derived from basic View class. So We can use a LayoutInflater
 * object to create a view and apply the background.
 */
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() {

                            view
                                    .setBackgroundResource(R.drawable.row_blue_menu);
                        }
                    });
                    return view;
                } catch (InflateException e) {
                } catch (ClassNotFoundException e) {
                }
            }
            return null;
        }
    });
}

。

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