改变SearchView控件文本输入光标及文字颜色

由于SearchView未提供修改文本输入光标及文字颜色属性的接口，在实际开发常有修改光标及文字颜色的需求，这时可通过反射机制来实现。具体如下：
......
import java.lang.reflect.Field;
......
        mSearchView = (SearchView) findViewById(R.id.navigation_search_bar);
        int searchPlateId = mSearchView.getContext().getResources()
                .getIdentifier("android:id/search_plate", null, null);
        View searchPlate = mSearchView.findViewById(searchPlateId);
        if (searchPlate != null) {
            int searchTextId = searchPlate.getContext().getResources()
                    .getIdentifier("android:id/search_src_text", null, null);
            //文字颜色
            TextView searchText = (TextView) searchPlate.findViewById(searchTextId);
            if (searchText != null) {
                searchText.setTextColor(Color.WHITE);
                searchText.setHintTextColor(Color.WHITE);
            }

            //光标颜色
            try {
                 Field mCursorDrawableRes=TextView.class.getDeclaredField("mCursorDrawableRes");
                 mCursorDrawableRes.setAccessible(true);
                 mCursorDrawableRes.set(searchText, R.drawable.cursor_color);
            } catch (Exception e){
                
            }
        }
......
//drawable/cursor_color.xml
