an annotation lib to create intent with extras and get extras

AptIntent

AptIntent是一个Android平台基于annotation的库，其目的是简化创建带数据的Intent和获取Intent内的数据。

使用方法

1.添加依赖

Gradle

在你的工程目录下的build.gradle添加android-apt插件,添加jitpack的maven库：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
    	...
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

allprojects {
	repositories {
		...
		maven { url "https://www.jitpack.io" }
	}
}

然后在你的模块下的build.gradle应用android-apt插件，添加AptIntent依赖：

apply plugin: 'android-apt'

android {
  ...
}

dependencies {
	compile 'com.github.zhl3391.AptIntent:aptintent:1.0.1'
	apt 'com.github.zhl3391.AptIntent:aptintent-compiler:1.0.1'
}

2.定义接口

public interface IntentCreator {

    String KEY_STRING       = "string";
    String KEY_INT          = "int";
    String KEY_BOOLEAN      = "boolean";
    String KEY_OBJECT       = "object";
    String KEY_ARRAY_LIST   = "array_list";
    String KEY_BUNDLE       = "bundle";

    @CreateIntent(MainActivity.class)
    Intent mainActivityIntent(Context context,
                              Bundle bundle,
                              @Extra(KEY_STRING)String stringTest,
                              @Extra(KEY_INT) int intTest,
                              @Extra(KEY_BOOLEAN) boolean booleanTest,
                              @Extra(KEY_OBJECT) ObjectTest objectTest,
                              @Extra(KEY_ARRAY_LIST) ArrayList<String> arrayListTest);
}

定义一个IntentCreator接口，定义一个mainActivityIntent的方法,通过@CreateIntent注解声明, 通过@Extra注解声明参数。
注：必须传入Context。

3.获取参数和跳转

public class MainActivity extends AppCompatActivity {

    @ExtraField(KEY_STRING)
    String mStringTest;
    @ExtraField(KEY_INT)
    int mIntTest;
    @ExtraField(KEY_BOOLEAN)
    boolean mBooleanTest;
    @ExtraField(KEY_OBJECT)
    ObjectTest mObjectTest;
    @ExtraField(KEY_ARRAY_LIST)
    ArrayList<String> mArrayListTest;
    @ExtraField(KEY_BUNDLE)
    String mBundleTest;

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

        AptIntent.bind(this);
    }

    public void jump(View view) {
        ArrayList<String> arrayList = new ArrayList<>();
        arrayList.add("arrayList");
        Bundle bundle = new Bundle();
        bundle.putString(KEY_BUNDLE, "bundle");
        Intent intent = AptIntent.create(IntentCreator.class).mainActivityIntent(this,
                bundle, "haha", 888, true, new ObjectTest(), arrayList);
        startActivity(intent);
    }
}

通过@ExtraField注解声明成员变量，调用AptIntent.bind(this)获取intent内数据。
调用AptIntent.create(IntentCreator.class)创建IntentCreator接口的实现，再调用mianActivityIntent创建intent。
注：@ExtraField注解的成员变量不能用private，static修饰。
