在Android Google Drive API中，可以使用Google账户进行账户登录，但是用户必须手动输入账户和密码。如果您想让应用程序自动使用预定义的Google账户进行身份验证，可以使用Android的Google API Client Library提供的GoogleAccountCredential类来实现.

首先，您需要在应用级别的build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'com.google.android.gms:play-services-auth:19.0.0'
}

接下来，在您的Activity中初始化Drive API客户端并设置Google帐户凭据。您可以直接从SharedPreferences中获取您的Google帐户的用户名和访问令牌。对于演示目的，下面是一个简单的示例代码：

import com.google.android.gms.auth.GoogleAuthException;
import com.google.android.gms.auth.GoogleAuthUtil;
import com.google.android.gms.auth.GooglePlayServicesAvailabilityException;
import com.google.android.gms.auth.GooglePlayServicesUtil;
import com.google.android.gms.auth.UserRecoverableAuthException;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.Scope;
import com.google.android.gms.drive.Drive;

public class MainActivity extends Activity {

    private static final int REQUEST_CODE_RESOLUTION = 1;
    private GoogleApiClient mGoogleApiClient;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Define the credential using the predefined Google account
        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
        String accountName = settings.getString(PREF_ACCOUNT_NAME, null);
        if (accountName != null) {
            GoogleAccountCredential credential = GoogleAccountCredential.usingOAuth2(
                    this, Arrays.asList(DriveScopes.DRIVE_FILE));
            credential.setSelectedAccountName(accountName);

            // Build the Drive API client
            mGoogleApiClient = new Builder(this)
                    .addApi(Drive.API)
                    .addScope(Drive.SCOPE_FILE)
                    .setAccountName(accountName)
                    .build();
        }
    }

    @Override
    protected void onStart() {
        super.onStart();
