Blackberry 如何更改黑莓应用程序中的荧光灯（蓝色）？

blackberry中的默认突出显示颜色为蓝色。我目前正在做一个主色调是红色的应用程序。有没有办法把荧光灯的颜色改成红色？我在谷歌上搜索了它，找到了列表字段的解决方案，其他字段如按钮、文本字段、位图字段等如何？

您可以覆盖自定义字段：

protected void drawFocus(Graphics g, boolean on) {
    // Custom focus painting
}

您可以覆盖自定义字段：

protected void drawFocus(Graphics g, boolean on) {
    // Custom focus painting
}

在blackberry论坛上找到了这个实现，并进行了尝试，效果非常好。但是，您需要为每个字段重写此方法，以便使用不同的高亮显示

protected void drawFocus( Graphics g, boolean on ) {    
    XYRect focusRect = new XYRect();                
    getFocusRect( focusRect );                
    int yOffset = 0;                

    if ( isSelecting() )     
    {        
        yOffset = focusRect.height >> 1;        
        focusRect.height = yOffset;        
        focusRect.y += yOffset;    
    }                
    g.pushRegion( focusRect.x, focusRect.y, 
                  focusRect.width, focusRect.height, 
                  -focusRect.x, -focusRect.y );   
    g.setBackgroundColor(/*your color here*/);    
    g.setColor( 0xFFFFFF );    
    g.clear();                
    this.paint( g );                
    g.popContext();
}
