Answer 1

您需要在gradle文件中添加此依赖项

compile 'com.android.support:design:23.1.1'

Answer 2

您需要将以下内容添加到模块build.gradle文件中：

implementation 'com.google.android.material:material:1.0.0'

并在XML中使用 com.google.android.material.textfield.TextInputLayout ：

   <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/text_input_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/my_hint">

Answer 3

Definitelly，您需要在位于build.gradle

内的/app文件中添加依赖项

dependencies {
    ...
    implementation 'com.android.support:design:27.0.1' //change compile to implementation
    ...
    }
}

但如果您仍在使用Eclipse，可能会在使用支持库时遇到一些问题，我建议您开始使用Android Studio。

<强> The Eclipse ADT plugin is no longer supported per our announcement. Android Studio现在是Android的官方IDE，所以你应该这样做尽快将项目迁移到Android Studio。更多有关转换到Android Studio的信息，请参阅迁移到Android 来自Eclipse的Studio。
