手机分辨率:
我想设计不同的屏幕 dpi，比如以下分辨率。
320x480、
480×800、
540x960、
720x1280(三星S3)、
1080x1920(S4、Nexus5、Nexus 5x、Moto G4)、
2560 x 1440(Nexus 6、Nexus 6p、三星边缘)

平板电脑分辨率:
480x800 (micromax) ,
600x1024 (samsung tab2),
800x1280 (nexus 7),
1200x1920 (new nexus 7),
2048x1536 (nexus 9)

我想根据设备的显示分辨率使用不同的字体大小。

Q1) 解决这个问题的最佳方法是什么？

Q2) 抛出编码或 XML 的最佳选择是什么？

Q3) 哪个可绘制文件夹代表哪个设备分辨率？

Q4) 不同分辨率的应用程序启动器图标大小？

最佳答案

不同分辨率的应用启动器图标大小(以像素为单位)

手机分辨率

• mipmap-mdpi (48X48)
• mipmap-hdpi (72X72)
• mipmap-xhdpi (96X96)
• mipmap-xxhdpi (144X144)
• mipmap-xxxhdpi (192X192)

平板电脑布局:

如果您希望拥有特定于平板电脑的布局，请使用以下文件夹:

layout-large-mdpi   (1024x600)
layout-large-tvdpi  (800x1280)
layout-large-xhdpi  (1200x1920)
layout-xlarge-mdpi  (1280x800)
layout-xlarge-xhdpi (2560x1600)

绘图文件夹:

1. 手机

   res/drawable        (default)
   res/drawable-ldpi/  (240x320 and nearer resolution)
   res/drawable-mdpi/  (320x480 and nearer resolution)
   res/drawable-hdpi/  (480x800, 540x960 and nearer resolution)
   res/drawable-xhdpi/  (720x1280 - Samsung S3, Micromax Canvas HD etc)
   res/drawable-xxhdpi/ (1080x1920 - Samsung S4, HTC one, Nexus 5, etc)
   res/drawable-xxxhdpi/ (1440X2560 - Nexus 6,Samsung S6edge).
   

2. 平板电脑分辨率:

   字体大小:

NOTE: Always try to use SP whenever you deal with textSize, like textsize=12sp

1. 使用预定义的textAppearance:

   它将根据设备密度自动设置文本大小。

   <TextView android:textAppearance="?android:attr/textAppearanceSmall"/>
   <TextView android:textAppearance="?android:attr/textAppearanceMedium"/>
   <TextView android:textAppearance="?android:attr/textAppearanceLarge" />
   

   示例用法:

   <TextView
       style="@android:style/TextAppearance.Small"
       android:text="Sample Text - Small" />
   <TextView
       style="@android:style/TextAppearance.Medium"
       android:text="Sample Text  - Medium" />
   <TextView
       style="@android:style/TextAppearance.Large"
       android:text="Sample Text  - Large" />
   

2. 对每个设备使用 dimension.xml:

   从 Google IO Pdf，我们看到以下结构:

   1. 手机:

      res/values/dimens.xml(default)
      res/values-ldpi/dimens.xml   (240x320 and nearer resolution)
      res/values-mdpi/dimens.xml   (320x480 and nearer resolution)
      res/values-hdpi/dimens.xml   (480x800, 540x960 and nearer resolution)
      res/values-xhdpi/dimens.xml  (720x1280 - Samsung S3, Micromax Canvas HD, etc)
      res/values-xxhdpi/dimens.xml (1080x1920 - Samsung S4, HTC one, etc)
      

      res/values-xxxhdpi/dimens.xml (1440X2560 - Nexus 6,Samsung S6edge).

   2. 平板电脑:

      对于平板电脑，您可以使用更具体的文件夹，例如 values-xlarge、values-large。

      res/values-large/dimens.xml      (480x800)
      res/values-large-mdpi/dimens.xml (600x1024)
      

      或

      res/values-sw600dp/dimens.xml      (600x1024)
      res/values-sw720dp/dimens.xml      (800x1280)
      res/values-xlarge-xhdpi/dimens.xml (2560x1600 - Nexus 10")
      res/values-large-xhdpi/dimens.xml  (1200x1920 - Nexus 7"(latest))
      

For further information:

1. Refer to Supporting Multiple Screens.

2. See Page# 77 of Google IO Pdf for Design device density. In that, you will find the way to handle dimens.xml for different different devices.

3. Getting Your Apps Ready for Nexus 6 and Nexus 9.

摘自 Supporting Multiple Screens :

The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. The conversion of dp units to screen pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels. You should always use dp units when defining your application's UI, to ensure proper display of your UI on screens with different densities.
