我用材料。我将为 TextInputLayout 使用一种颜色作为背景，但类似于下面的颜色！提示背景未更改。我使用了样式并想进行更改，但没有奏效。在布局本身中，我尝试再次应用更改！如何解决这个问题？

笔记

图片中标签用户名的背景不透明，它覆盖了一些TextInputEditText

在build.gradle 中

implementation 'com.google.android.material:material:1.1.0'

在风格

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>

我要建立一个项目。当我创建项目时，遇到以下错误

ERROR: Failed to resolve: espresso-core

和我的 build.gradle(module) 文件

我想使用 Retrofit2 和 rxjava3 但我看到以下错误

Caused by: java.lang.IllegalArgumentException: Could not locate call adapter for io.reactivex.rxjava3.core.Observable<java.lang.Object>.
      Tried:
       * retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory
       * retrofit2.CompletableFutureCallAdapterFactory
       * retrofit2.DefaultCallAdapterFactory

此错误表明Rxjava 没有适配器，但我将其添加到下面的行中

.addCallAdapterFactory(RxJava2CallAdapterFactory.create())

public class ServiceGenerator {
  private static final String BASE_URL = "http://example.com/";
  private static final OkHttpClient okHttpClient = new OkHttpClient.Builder()

    .connectTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .build();

  public static <S> S createServiceSample(Class<S> serviceClass) {
    Retrofit.Builder builder =
      new Retrofit.Builder()
        .client(okHttpClient)
        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
        .addConverterFactory(GsonConverterFactory.create());
    builder.baseUrl(BASE_URL);
    Retrofit retrofit = builder.build();
    return retrofit.create(serviceClass);
  }

}

和我的 Api 接口 …

我使用的是Android Studio 4.0.1。当我尝试生成程序的调试版本时，出现以下错误。（生成发布版本没问题！）
