黑莓可点击BitmapField [英] Blackberry Clickable BitmapField

问题描述

我要创建自定义BitmapField为把图标在我的菜单屏幕。我希望他们被点击。我也想给X和图标作为参数传递给自定义BitmapField的Y坐标。我该怎么做？

解决方案

 公共类CustomMenuButtonField扩展字段{
位图正常，重点突出;
公共CustomMenuButtonField（字符串bitmap1，字符串bitmap2）{    正常= Bitmap.getBitma $ P $的PSource（bitmap1）;
    专注= Bitmap.getBitma $ P $的PSource（bitmap2）;}保护无效布局（INT宽度，高度INT）{
    setExtent（宽度，高度）; //根据你的设计他们设置
}保护布尔navigationClick（INT的地位，诠释时间）
{
    fieldChangeNotify（0）;
    返回true;
}公共布尔isFocusable（）{
    返回true;
}保护无效漆（图形图像）{    如果（isFocus（））
    {
        graphics.drawBitmap（0，0，宽度，高度，突出重点，0，0）;
    }
    其他
    {
        graphics.drawBitmap（0，0，宽度，高度，正常，0，0）;
    }}
 

}

如果你想给坐标参数，添加它们。高度和宽度是由你..

I want to create a Custom BitmapField for putting Icons on my Menu Screen. I want them to be Clicked. I also want to give the X and Y coordinates of the icon as parameter to the Custom BitmapField. How can I do that?

解决方案

public class CustomMenuButtonField extends Field{
Bitmap normal,focused;
public CustomMenuButtonField(String bitmap1, String bitmap2) {

    normal = Bitmap.getBitmapResource(bitmap1);
    focused = Bitmap.getBitmapResource(bitmap2);

}

protected void layout(int width, int height) {
    setExtent(width, height); // Set them according to your design  
}

protected boolean navigationClick(int status, int time)
{
    fieldChangeNotify(0);
    return true;
}

public boolean isFocusable() {
    return true;
}

protected void paint(Graphics graphics) {

    if(isFocus())
    {
        graphics.drawBitmap(0, 0, width, height, focused, 0, 0);
    }
    else
    {
        graphics.drawBitmap(0, 0, width, height, normal, 0, 0);
    }

}

}

If you want to give coordinates as parameters , add them. Height and width is up to you..
