android - 将像素转换为dp(Converting pixels to dp)

Question

I have created my application with the height and width given in pixels for a Pantech device whose resolution is 480x800.

(我创建了我的应用程序，其高度和宽度以像素为单位，用于分辨率为480x800的Pantech设备。)

I need to convert height and width for a G1 device.

(我需要转换G1设备的高度和宽度。)

I thought converting it into dp will solve the problem and provide same solution for both devices.

(我认为将其转换为dp将解决问题，并为两个设备提供相同的解决方案。)

Is there any easy way to convert pixels to dp?

// Converts 14 dip into its equivalent px
float dip = 14f;
Resources r = getResources();
float px = TypedValue.applyDimension(
    TypedValue.COMPLEX_UNIT_DIP,
    dip,
    r.getDisplayMetrics()
);
