6.例示调用（这里继承了AppCompatButton作为例示）

7.Google登录接口之控制台配置

1.基础配置

  1. //Google登录引用包
  2. api 'com.google.android.gms:play-services-auth:19.0.0'
  3.  
  4. //Client ID（values/strings.xml）
  5. <string name="server_client_id">客户端ID</string>

3.GoogleLogIn（实现类接口）

  1. import android.app.Activity;
  2. import android.content.Context;
  3. import android.content.Intent;
  4. import android.view.View;
  5.  
  6. import androidx.annotation.NonNull;
  7. import androidx.annotation.Nullable;
  8.  
  9. import com.google.android.gms.common.api.Scope;
  10.  
  11. public interface GoogleLogIn {
  12.     static GoogleLogIn create(Context context) { return new GoogleLogInImpl( context ); }
  13.  
  14.     void registerCallback(@NonNull Activity activity, GoogleCallback call);
  15.  
  16.     GoogleBuild requestIdToken();
  17.  
  18.     GoogleBuild requestEmail();
  19.  
  20.     GoogleBuild requestGender();
  21.  
  22.     GoogleBuild requestId();
  23.  
  24.     GoogleBuild requestProfile();
  25.  
  26.     GoogleBuild requestScopes(Scope scope, Scope... scopes);
  27.  
  28.     GoogleBuild requestServerAuthCode(String s);
  29.  
  30.     GoogleBuild requestServerAuthCode(String s, boolean b);
  31.  
  32.     void onClick(View v);
  33.  
  34.     void onActivityResult(int requestCode, int resultCode, @Nullable Intent data);
  35. }

4.GoogleCallback（登录授权回调接口）

  1. import com.google.android.gms.auth.api.signin.GoogleSignInAccount;
  2.  
  3. /**
  4.  * 登录授权回调
  5.  */
  6. public interface GoogleCallback {
  7.     /**
  8.      * 授权成功
  9.      * @param account   授权信息
  10.      * @param isFirst   之前是否授权过
  11.      */
  12.     void onSuccess(GoogleSignInAccount account, boolean isFirst);
  13.     /**
  14.      * 取消授权
  15.      */
  16.     void onCancel();
  17.     /**
  18.      * 授权失败
  19.      */

  5. import com.google.android.gms.auth.api.signin.GoogleSignInOptions;
  6. import com.google.android.gms.common.api.Scope;
  7. import com.og.login.R;
  8.  
  9. import java.lang.annotation.Retention;
  10. import java.lang.annotation.RetentionPolicy;
  11. import java.lang.ref.WeakReference;
  12.  
  13. public class GoogleBuild {
  14.     @Retention(RetentionPolicy.SOURCE)
  15.     public @interface SignIn {
  16.         GoogleSignInOptions DEFAULT_SIGN_IN = GoogleSignInOptions.DEFAULT_SIGN_IN;
  17.         GoogleSignInOptions DEFAULT_GAMES_SIGN_IN = GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN;
  18.     }
  19.  
  20.     private final GoogleSignInOptions.Builder mBuild;
  21.     private final WeakReference<Context> mWRContext;
  22.  
  23.     private GoogleBuild(Context context, @SignIn GoogleSignInOptions signIn) {
  24.         mWRContext = new WeakReference<>( context );
  25.         mBuild = new GoogleSignInOptions.Builder( signIn );
  26.     }
  27.  
  28.     /**
  29.      * 以默认的方式登录
  30.      * @return      Build
  31.      */
  32.     public static GoogleBuild create(Context context) {
  33.         return new GoogleBuild( context, SignIn.DEFAULT_SIGN_IN );
  34.     }
  35.  
  36.     /**
  37.      * 以游戏的方式登录
  38.      * @return      Build
  39.      */
  40.     public static GoogleBuild createGame(Context context) {
  41.         return new GoogleBuild( context, SignIn.DEFAULT_GAMES_SIGN_IN );
  42.     }
  43.  
  44.     public GoogleBuild requestIdToken() {
  45.         mBuild.requestIdToken( mWRContext.get()
  46.                 .getResources()
  47.                 .getString( R.string.server_client_id )
  48.         );
  49.         return this;
  50.     }
  51.  
  52.     public GoogleBuild requestEmail() {
  53.         mBuild.requestEmail();
  54.         return this;
  55.     }
  56.  
  57.     public GoogleBuild requestGender() {
  58.         mBuild.requestScopes( new Scope( "https://www.googleapis.com/auth/user.gender.read" ) );
  59.         return this;
  60.     }
  61.  
  62.     public GoogleBuild requestId() {
  63.         mBuild.requestId();
  64.         return this;
  65.     }
  66.  
  67.     public GoogleBuild requestProfile() {
  68.         mBuild.requestProfile();
  69.         return this;
  70.     }
  71.  
  72.     public GoogleBuild requestScopes(Scope scope, Scope... scopes) {

  88.         return GoogleSignIn.getClient( mWRContext.get(), mBuild.build() );
  89.     }
  90. }

6.例示调用（这里继承了AppCompatButton作为例示）

  1. import android.app.Activity;
  2. import android.content.Context;
  3. import android.content.Intent;
  4. import android.util.AttributeSet;
  5. import android.view.View;
  6.  
  7. import androidx.annotation.NonNull;
  8. import androidx.annotation.Nullable;
  9. import androidx.appcompat.widget.AppCompatButton;
  10.  
  11. import com.google.android.gms.common.api.Scope;
  12. import com.og.login.google.GoogleBuild;
  13. import com.og.login.google.GoogleCallback;
  14. import com.og.login.google.GoogleLogIn;
  15.  
  16. public class GoogleLoginButton extends AppCompatButton implements GoogleLogIn {
  17.     private final GoogleLogIn mLogin;
  18.  
  19.     public GoogleLoginButton(Context context) {
  20.         this(context, null);
  21.     }
  22.  
  23.     public GoogleLoginButton(Context context, AttributeSet attrs) {
  24.         this(context, attrs, 0);
  25.     }
  26.  
  27.     public GoogleLoginButton(Context context, AttributeSet attrs, int defStyleAttr) {
  28.         super(context, attrs, defStyleAttr);
  29.         mLogin = GoogleLogIn.create( context );
  30.         mLogin.requestEmail();
  31. //        mLogin.requestGender();
  32.     }
  33.  
  34.     @Override
  35.     public void registerCallback(@NonNull Activity activity, GoogleCallback call) {
  36.         mLogin.registerCallback( activity, call );
  37.     }
  38.  
  39.     @Override
  40.     public GoogleBuild requestIdToken() { return mLogin.requestIdToken(); }
  41.  
  42.     @Override
  43.     public GoogleBuild requestEmail() { return mLogin.requestEmail(); }
  44.  
  45.     @Override
  46.     public GoogleBuild requestGender() { return mLogin.requestGender(); }
  47.  
  48.     @Override
  49.     public GoogleBuild requestId() { return mLogin.requestId(); }
  50.  
  51.     @Override
  52.     public GoogleBuild requestProfile() { return mLogin.requestProfile(); }
  53.  
  54.     @Override
  55.     public GoogleBuild requestServerAuthCode(String s) { return mLogin.requestServerAuthCode( s ); }
  56.  
  57.     @Override
  58.     public GoogleBuild requestServerAuthCode(String s, boolean b) {
  59.         return mLogin.requestServerAuthCode( s, b );
  60.     }
  61.  
  62.     @Override
  63.     public GoogleBuild requestScopes(Scope scope, Scope... scopes) {
  64.         return mLogin.requestScopes( scope, scopes );
  65.     }
  66.     
  67.     @Override
  68.     public void onClick(View v) {
  69.         mLogin.onClick( v );
  70.     }
  71.  
  72.  
  73.     @Override
  74.     public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
  75.         mLogin.onActivityResult( requestCode, resultCode, data );
  76.     }
