ActivityResultLauncher

基于官方api，开发的代替startActivityForResult和requestPermission，这两个方法是常用的，官方还提供了其他的api，可根据需要自行继承BaseActivityResultLauncher

在根目录的build.gradle添加如下代码：

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

在工程目录的build.gradle添加如下代码：

dependencies {
   implementation 'com.github.op123355569:ActivityResultLauncher:lastVersion'
}

Java用法：

// StartActivityForResult
ProxyStartActivityForResult startActivityForResult1 = new ProxyStartActivityForResult(this);
startActivityForResult1.launch(new Intent(JavaActivity.this, ResultActivity.class), result -> {
    if (result != null) {
        int resultCode = result.getResultCode();
        String name = "";
        int age = 0;

        if (result.getData() != null) {
            name = result.getData().getStringExtra("name");
            age = result.getData().getIntExtra("age", age);
        }

        Log.e("Java", "ResultCode:" + resultCode + ",name:" + name + ",age:" + age);
    }
});
           
// RequestPermission
ProxyRequestPermission requestPermission1 = new ProxyRequestPermission(this);
requestPermission1.launch(
    (result, isAgreeAll) -> Log.e("Java", "权限是否全部同意：" + isAgreeAll),
    Manifest.permission.CAMERA
));

Kotlin用法：

// StartActivityForResult
val startActivityForResult1 = ProxyStartActivityForResult(this)
startActivityForResult1.launch(Intent(this, ResultActivity::class.java), object : OnActivityResultListener {
    override fun onActivityResult(result: ActivityResult?) {
        val resultCode = result?.resultCode
        val name = result?.data?.getStringExtra("name")
        val age = result?.data?.getIntExtra("age", 0)
        Log.e("Kotlin", "ResultCode:$resultCode,name:$name,age:$age")
    }
})

// RequestPermission
requestPermission1 = ProxyRequestPermission(this)
requestPermission1.launch(
    object : OnRequestPermissionsResultListener {
        override fun onRequestPermissionsResult(result: Map<String, Boolean>, isAgreeAll: Boolean) {
            Log.e("Kotlin", "权限是否全部同意：$isAgreeAll")
        }
    },
    Manifest.permission.CAMERA
)

具体用法Demo中有写。
