Usage

---

1. Gradle dependency

   // app module gradle
   implementation 'com.github.parcool:AnInterceptor:latestRelease'

   // root gradle 
   allprojects {
   	repositories {
   		maven { url 'https://jitpack.io' }
   	}
   }

2. How to use? Show me the code!

• Override the startActivityForResult method in your BaseActivity.

  @Override
  public void startActivityForResult(Intent intent, int requestCode, @Nullable Bundle options) {
      if (intent != null) {
          if (options != null && options.getBoolean(AnConstant.REQUIRE_BREAK, false)) {
              super.startActivityForResult(intent, requestCode, options);
          }
          AnInterceptor.startActivityForResult(this, intent, requestCode, options);
      }
  }
  

• New LoginInterceptor to intercept the route request.

  public class LoginInterceptor implements HandlerInterceptor {
  
      WeakReference<Activity> activityRef;
  
      public LoginInterceptor(Activity activity) {
          activityRef = new WeakReference<>(activity);
      }
  
      @Override
      public boolean preHandle() {
          //return false means handle this, or pass this intercept
          return SPUtils.getInstance().getBoolean("login", false);
      }
  
      @Override
      public void handle() {
          //if logout we need startActivity to target activity
          activityRef.get().startActivity(new Intent(activityRef.get(), LoginActivity.class));
      }
  }
  

• Add AnInterceptor.trigger() after login success in your LoginActivity class.

  ……
  btnLogin.setOnClickListener {
      //login code such as:  
      SPUtils.getInstance().put("login", true)
      finish()
      //Add this method to completed this interceptor
      AnInterceptor.trigger()    
  }
  ……
  

• Add Interceptor annotation on NeedLogonActivity class which require logon.

  @Interceptor(interceptors = {LoginInterceptor.class})
  public class NeedLogonActivity extends BaseActivity {
  
      @Override
      protected void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          ……
      }
  }    
  

• OK, Now we can handle all request(startActivity) which to NeedLogonActivity. Such as:

  btn_to_need_logon_activity.setOnClickListener {
      //Tips: this code must in SubClass which extends BaseActivity    
      startActivity(new Intent(this, NeedLogonActivity.class));
  }
  

What it takes for me? ---Time!

• We don't need this code any more.

  boolean isLogon = SPUtils.getInstance().getBoolean("login", false);
  if (isLogon) {
      startActivity(new Intent(this, NeedLogonActivity.class));
  } else {
      startActivity(new Intent(this, LoginActivity.class));
  }
  

• More than one interceptor on the same Activity?

  See example

• If user login success it will be auto intent to NeedLogonActivity

  

Proguard

-keep class * implements com.parcool.internal.HandlerInterceptor{<init>(*);}

Important!

This lib is not stable, Don't use it to production environment.I'm very glad for you make PR to improve it!
