Telusuri konten

Meminta generator tampilan UI konten penelusuran

Kami telah menambahkan dukungan untuk menampilkan tampilan UI konten penelusuran di SDK. Search Content adalah istilah umum yang mewakili beberapa jenis fitur konten. Lihat bagian berikut untuk mengetahui cara meminta setiap jenis fitur konten.

Pengulangan penelusuran

Untuk mendapatkan tampilan UI untuk pengulangan penelusuran, Anda harus mendapatkan generator konten penelusurannya terlebih dahulu dengan langkah-langkah berikut:

1. Ganti metode onSuccess dan onError class GetSearchContentViewGeneratorCallback.
2. Buat instance untuk class GetSearchContentViewGeneratorCallback.
3. Buat instance class GetSearchContentViewOptions dan tetapkan konteks pengulangan penelusuran dengan memanggil metode setSearchRepeatContext. (Opsional) Objek ini juga menggunakan objek SearchContentViewOptions yang menyediakan beberapa opsi untuk menyesuaikan tampilan UI.
4. Panggil fungsi getSearchContentView(GetSearchContentViewOptions, GetSearchContentViewGeneratorCallback) SearchInAppsService.
5. Setelah mendapatkan generator UI, Anda dapat mempertimbangkan untuk menyimpannya di ViewModel sehingga tidak perlu meminta generator lagi saat aktivitas perlu dibuat ulang (seperti saat konfigurasi telah berubah saat aplikasi berjalan).

Kode contoh

Java

package ...;

...
import androidx.appcompat.app.AppCompatActivity;
import com.google.android.libraries.searchinapps.GetSearchContentViewGeneratorCallback;
import com.google.android.libraries.searchinapps.GetSearchContentViewOptions;
import com.google.android.libraries.searchinapps.SearchInAppsService;
import com.google.android.libraries.searchinapps.SearchContentViewGenerator;
...

public class MainActivity extends AppCompatActivity {
  private SearchInAppsService service;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    ...
    service = SearchInAppsService.create(this);
    GetSearchContentViewGeneratorCallback searchContentCallback =
      new GetSearchContentViewGeneratorCallback() {
        @Override
        public void onSuccess(SearchContentViewGenerator generator) {
          ...
        }

        @Override
        public void onError(String errorMessage) {
          ...
        }
      };

    // Uses the default SearchContentViewOptions.
    service.getSearchContentView(
      new GetSearchContentViewOptions().setSearchRepeatContext(
          "sample search repeat"), searchContentCallback);
    ...
  }

  @Override
  public void onDestroy() {
    service.shutDown();
    super.onDestroy();
  }
}

Jetpack Compose

package ...

...
import android.os.Bundle
import androidx.activity.compose.setContent
import androidx.appcompat.app.AppCompatActivity
import androidx.compose.runtime.Composable
import androidx.compose.runtime.DisposableEffect
import androidx.compose.runtime.mutableStateOf
import androidx.compose.ui.platform.LocalContext
import com.google.android.libraries.searchinapps.GetSearchContentViewGeneratorCallback
import com.google.android.libraries.searchinapps.GetSearchContentViewOptions
import com.google.android.libraries.searchinapps.SearchInAppsService
import com.google.android.libraries.searchinapps.SearchContentViewGenerator
...

class MainActivity : AppCompatActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
      SearchRepeatUI()
    }
  }

  @Composable
  fun SearchRepeatUI() {
    ...
    var service by remember {
      mutableStateOf<SearchInAppsService?>(
        SearchInAppsService.create(LocalContext.current))
    }
    DisposableEffect(Unit) { onDispose { service?.shutDown() } }
    val callback =
            object : GetSearchContentViewGeneratorCallback() {
              override fun onSuccess(generator: SearchContentViewGenerator) {
                ...
              }

              override fun onError(errorMessage: String) {
                ...
              }
            }
    // Uses the default SearchContentViewOptions.
    var options: GetSearchContentViewOptions =
            GetSearchContentViewOptions()
              .setSearchRepeatContext("sample search repeat")
    service?.let { service ->
      service.getSearchContentView(options, callback)
    }
    ...
  }
}

Menambahkan Tampilan UI konten penelusuran

Untuk getSearchContentView, output akhir adalah objek SearchContentViewGenerator. Anda dapat menggunakan fungsi populateView(Context, int) objek ini untuk membuat tampilan UI dan updateView(View, Context) untuk mengupdate tampilan yang ada (terutama untuk aplikasi Jetpack Compose).

Untuk aplikasi Jetpack Compose, Anda harus menggunakan AndroidView untuk menggunakan tampilan klasik yang dihasilkan.

public class MainActivity extends AppCompatActivity {

  @Override

    ...
    service = SearchInAppsService.create(this);
    GetSearchContentViewGeneratorCallback searchContentCallback =
      new GetSearchContentViewGeneratorCallback() {
        @Override
        public void onSuccess(SearchContentViewGenerator generator) {
          ViewGroup container = findViewById(R.id.[container_id]);
          container.removeAllViews();
          searchContentBlock = 0;
          // If you don't specify "numberOfBlocksToRequest" in
          // GetSearchContentViewOptions, by default
          // SearchContentViewGenerator.getSearchContentBlockCount() always
          // returns 1.
          while (searchContentBlock <
            generator.getSearchContentBlockCount()) {
              container.addView(
                  generator.populateView(MainActivity.this,
                    searchContentBlock));
              searchContentBlock++;
          }
        }

        @Override
