添加依赖

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

latest_version

Kotlin

   implementation 'com.github.iDeMonnnnnn.DeMon-ARA:core-ktx:$latest_version'
   //你自己项目的activity-ktx库
   implementation 'androidx.activity:activity-ktx:1.4.0'
    //你自己项目的fragment-ktx库
   implementation 'androidx.fragment:fragment-ktx:1.4.1'

Java

   implementation 'com.github.iDeMonnnnnn.DeMon-ARA:core:$latest_version'
   //你自己项目的activity库
   implementation 'androidx.activity:activity:1.4.0'
   //你自己项目的fragment库
   implementation 'androidx.fragment:fragment:1.4.1'

使用

1.初始化

class App : Application() {

    override fun onCreate() {
        super.onCreate()
        DeMonAraHelper.init(this)
    }
}

2.Kotlin代码中使用

kotlin的进一步封装使用可见ActivityResultApi.kt

val intent = Intent(this@MainActivity, JavaActivity::class.java)
forActivityResult(intent) {
     val str = it?.getStringExtra("tag") ?: ""
     text.text = "跳转页面返回值：$str"
}

3.Java代码中使用

    DeMonActivityResult<Intent, ActivityResult> result = DeMonAraHelper.getActivityResult(JavaActivity.this);
            if (result != null) {
        result.launch(new Intent(this, TestJumpActivity.class), true,
                data -> {
                    if (data.getData() != null) {
                        String str = data.getData().getStringExtra("tag");
                        binding.text.setText("跳转页面返回值：" + str);
                    } else {
                        binding.text.setText("我是返回键返回的，没有返回值~");
                    }
                });
    }

Benchmark

我们简单测试一下以下四种方式直接执行100次时的性能。

测试代码可见：BenchmarkActivity.kt

测试机型：小米5

方式	1(ms)	2(ms)	3(ms)	4(ms)	5(ms)
startActivityForResult()/onActivityResult()	6638	6638	6605	6597	6687
GhostFragment	6589	6752	6555	6553	6572
Activity Results API	6586	6786	6708	6666	6604
DeMon-ARA	6974	6851	6901	6912	6839

内存方面：测试过程中使用AndroidStudio Profiler监测的内存波动基本一致。
