If you uses AndroidStudio, you should not include android-support-design.jar. Instead, write like below in your build.gradle:
如果您使用 AndroidStudio，则不应包含 android-support-design.jar。相反，在你的 build.gradle 中像下面这样写：
dependencies {
...
compile 'com.android.support:design:24.0.0'
...
}
Edit: If this doesn't work you are probably using a different version. In Windows, go to:
编辑：如果这不起作用，您可能正在使用不同的版本。在 Windows 中，转到：
[android-sdk]\extras\android\m2repository\com\android\support\design
On Mac:
在 Mac 上：
sdk/extras/android/m2repository/com/android/support/design
This directory holds a number of version folders. Use the latest version on your build.gradle.
该目录包含许多版本文件夹。在 build.gradle 上使用最新版本。

add in the build.gradle following this line:
在此行后面的 build.gradle 中添加：
implementation 'com.android.support:design:28.0.0'
and use in the xml file:
并在 xml 文件中使用：
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/inputLayoutMobile"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dimen_20dp"
android:layout_marginRight="@dimen/dimen_20dp"
android:hint="@string/phone_number"
android:visibility="gone"
android.support.design:layout_constraintTop_toBottomOf="@+id/inputLayoutAppServerUrl">
<com.google.android.material.textfield.TextInputEditText

style="@style/Style_TextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableLeft="@drawable/ic_smartphone"

The dependency your using is part of the Android support library which is now deprecated and no longer supported by Google. Instead, use this:implementation 'com.google.android.material:material:<version>'
and replace <version>with the latest version from either Google's Maven Repositoryor MVN Repository
您使用的依赖项是 Android 支持库的一部分，该库现已弃用且不再受 Google 支持。相反，使用这个：implementation 'com.google.android.material:material:<version>'
并替换<version>为来自Google 的 Maven 存储库或MVN 存储库的最新版本
