将像素转换为 dp [英] Converting pixels to dp

问题描述

我已经为分辨率为 480x800 的 Pantech 设备创建了高度和宽度(以像素为单位)的应用程序.

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

我需要为 G1 设备转换高度和宽度.
我认为将其转换为 dp 将解决问题并为两种设备提供相同的解决方案.

I need to convert height and width for a G1 device.
I thought converting it into dp will solve the problem and provide the same solution for both devices.

有没有什么简单的方法可以将像素转换为dp?
有什么建议吗?

Is there any easy way to convert pixels to dp?
Any suggestions?

推荐答案

Java 代码:

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

Kotlin 代码:

 val dip = 14f
 val r: Resources = resources
 val px = TypedValue.applyDimension(
     TypedValue.COMPLEX_UNIT_DIP,
     dip,
     r.displayMetrics
 )

Kotlin 扩展:

val Number.toPx get() = TypedValue.applyDimension(
  TypedValue.COMPLEX_UNIT_DIP,
  this.toFloat(),
  Resources.getSystem().displayMetrics)
