Retrofit 2.0-beta でログを吐かせる

Last updated : 2022-03-18 17:23

Retrofit

Okhttp 2.6.0+ では HTTPリクエスト/レスポンスのログ出力が可能なのだが,

New Logging Interceptor. The logging-interceptor subproject offers simple request and response logging. It may be configured to log headers and bodies for debugging. It requires this Maven dependency:

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
client.networkInterceptors().add(logging);

okhttp/CHANGELOG.md at master · square/okhttp

残念なことに retrofit 2.0.0-beta2 での同梱は 2.5.0 .

<!-- Dependencies -->
<android.version>4.1.1.4</android.version>
<android.platform>16</android.platform>
<okhttp.version>2.5.0</okhttp.version>
<animal.sniffer.version>1.14</animal.sniffer.version>

retrofit/pom.xml at master · square/retrofit

なので logging-interceptor 2.6.0 で.

    <dependency>
      <groupId>com.squareup.okhttp</groupId>
      <artifactId>okhttp</artifactId>
      <version>${project.version}</version>
    </dependency>

okhttp/okhttp-logging-interceptor at master · square/okhttp

compile 'com.squareup.okhttp:logging-interceptor:2.6.0'

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();  
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient();  
httpClient.interceptors().add(logging);
Retrofit retrofit = new Retrofit.Builder()  
   .baseUrl(API_BASE_URL)
   .addConverterFactory(GsonConverterFactory.create())
   .client(httpClient)
   .build();

出力.

stable で対応するのかな.

android-apt でアノテーションを便利に

Last updated : 2015-11-19 09:30

このプラグインを追加すると、gradle のソースフォルダとして認識される場所に Butter Knife で生成されるコードが格納されます。
そのため、Butter Knife で生成されたクラスも Lint から見えるようになり、Lint が怒らなくなります。やったー。

Y.A.M の雑記帳: Butter Knife のフィールドやメソッドが Lint に Unused declaration と言われないようにする方法

JakeWharton commented on Sep 26
If you use the android-apt plugin then Android Studio can see the generated code and the method will not show up as unused.

Lint: Unused resource · Issue #356 · JakeWharton/butterknife

Bitbucket で公開されています.

The android-apt plugin assists in working with annotation processors in combination with Android Studio. It has two purposes:
Allow to configure a compile time only annotation processor as a dependency, not including the artifact in the final APK or library
Set up the source paths so that code that is generated from the annotation processor is correctly picked up by Android Studio.

Butter Knife 以外にも使えるのか.

わーい.

RecyclerView アイテム内ある要素のクリックイベント

Last updated : 2022-06-21 13:59

いろんな実装が可能なのですが.


public class ItemsAdapter extends RecyclerView.Adapter<ItemsAdapter.ViewHolder> {

  // ...

  private static ItemsAdapter.OnItemClickListener listener;

  public void setOnItemClickListener(ItemsAdapter.OnItemClickListener listener) {
    ItemsAdapter.listener = listener;
  }

  public interface OnItemClickListener {
    void onItemClick(View view, int position);
  }

  // ...

  public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    public ViewHolder(final View itemView) {
      super(itemView);

      name = (TextView) itemView.findViewById(R.id.name);
      age = (TextView) itemView.findViewById(R.id.age);
      button = (Button) itemView.findViewById(R.id.button);

      name.setOnClickListener(this);
      age.setOnClickListener(this);
      button.setOnClickListener(this)
    }

    @Override
    public void onClick(View v) {
      if (listener != null) {
        listener.onItemClick(v, getLayoutPosition());
      }
    }

  }
}

UI.


public class MainFragment extends Fragment
    implements ItemsAdapter.OnItemClickListener {

  // ...

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   
    // ...
    mAdapter.setOnItemClickListener(this);
  }

  @Override
  public void onItemClick(View view, int position) {
    switch (view.getId()) {
      case R.id.name:
        // ...
        break;  
        // ...
  }

    // ...
}

ここらなんだろうな.
