Android 文本中的 dp 或 sp
dp or sp in Android Text
我有一个关于 Android 的问题，我需要你的帮助。我有以下单选按钮：
<RadioButton
android:id="@+id/r_Button_Standard"
android:layout_width="95dp"
android:layout_height="35dp"
android:layout_weight="1"
android:background="@drawable/background_selector"
android:text="@string/radioButton_standard"
android:checked="true"
android:textColor="@drawable/text_selector"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.642"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginLeft="10dp"
app:layout_constraintVertical_bias="0.671" />
看起来像这样：
现在 Android Studio 生成警告告诉我使用 "Should use "sp" instead of "dp" for text sizes" 并进一步告诉 "There are cases where you might need to use dp; typically this happens when the text is in a container with a specific dp-size. This will prevent the text from spilling outside the container. Note however that this means that the user's font size settings are not respected, so consider adjusting the layout itself to be more flexible."
所以现在我的问题是该怎么做？基本上，文本在一个容器中，显然不应该溢出到容器之外。所以我认为我应该使用 dp。 “更灵活的布局”是什么意思？
评论：虽然 'IntelliJ Amiya' 关闭了这个问题并给了一个 link 根据他的观点回答我的问题的问题 (Should use "sp" instead of "dp" for text sizes) 我不得不说事实上它没有。我说的是容器内的文本，而不是一般文本。

对于屏幕上的文本，我们更喜欢 sp，因为如果用户想通过设置更改文本大小（例如：小、中、大），这些文本会根据屏幕自动缩放。但是在 dp 的情况下，每个 phone 具有不同的像素密度（例如：在 4 x 4 正方形 space 中，某些 phone 可能有 4 个像素，而某些 phone 可能有 16 个像素一些其他phone), 所以不推荐使用dp.
阅读本文以全面了解 SP、DP 和 Piexel：
TL;DR
SP == DP，但用户在设备设置应用中对字体大小的偏好也将应用于
考虑到用户在设置中增加了字体大小，他可能希望在您的应用程序中看到更大的字体大小，sp 会解决这个问题。

我有一个关于 Android 的问题，我需要你的帮助。我有以下单选按钮：
<RadioButton

android:layout_width="95dp"
android:layout_height="35dp"
android:layout_weight="1"
android:background="@drawable/background_selector"
android:text="@string/radioButton_standard"
android:checked="true"
android:textColor="@drawable/text_selector"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.642"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginLeft="10dp"
app:layout_constraintVertical_bias="0.671" />
看起来像这样："Should use "sp" instead of "dp" for text sizes" 并进一步告诉 "There are cases where you might need to use dp; typically this happens when the text is in a container with a specific dp-size. This will prevent the text from spilling outside the container. Note however that this means that the user's font size settings are not respected, so consider adjusting the layout itself to be more flexible."
所以现在我的问题是该怎么做？基本上，文本在一个容器中，显然不应该溢出到容器之外。所以我认为我应该使用 dp。 “更灵活的布局”是什么意思？
评论：虽然 'IntelliJ Amiya' 关闭了这个问题并给了一个 link 根据他的观点回答我的问题的问题 (Should use "sp" instead of "dp" for text sizes) 我不得不说事实上它没有。我说的是容器内的文本，而不是一般文本。

对于屏幕上的文本，我们更喜欢 sp，因为如果用户想通过设置更改文本大小（例如：小、中、大），这些文本会根据屏幕自动缩放。但是在 dp 的情况下，每个 phone 具有不同的像素密度（例如：在 4 x 4 正方形 space 中，某些 phone 可能有 4 个像素，而某些 phone 可能有 16 个像素一些其他phone), 所以不推荐使用dp.
阅读本文以全面了解 SP、DP 和 Piexel：
TL;DR
SP == DP，但用户在设备设置应用中对字体大小的偏好也将应用于
考虑到用户在设置中增加了字体大小，他可能希望在您的应用程序中看到更大的字体大小，sp 会解决这个问题。

- 你对 LinearLayout 权重的使用是完全错误的
- 您大量使用固定 dp 大小 https://developer.android.com/training/multiscreen/screendensities
