ActivityResultHelper

一行代码实现权限请求、startActivityForResult、调用相机拍照及调用相机录像等，消除onActivityResult()、onRequestPermissionsResult()回调导致的代码分散的问题；支持协程

request permissions 请求权限

1. 请求单个权限

// AppCompatActivity or Fragment
requestPermission(Manifest.permission.CAMERA) {
    // ...
}

2. 请求多个权限

// AppCompatActivity or Fragment
requestPermissions(
    arrayOf(
        Manifest.permission.CAMERA,
        Manifest.permission.RECORD_AUDIO
    )) {
    // ...    
}

3. 常见的权限，可以自定义

// AppCompatActivity or Fragment
requestCameraPermission {
    // ...
}

4. 对协程的支持

lifecycleScope.launch {
    if (!requestPermissionSuspend(Manifest.permission.CAMERA)) {
        return@launch
    }
    // ...
}

startActivityForResult

val intent = Intent(this, ActivityResultsDestinationActivity::class.java)
intent.putExtra("from", "MainActivity")
intent.putExtra("input", 12306)
startActivityForResultExt(intent) { data->
    // ...
}

takePicture 调用系统相机拍照

val imageFile = File(getExternalFilesDir("image"), "temp.jpg")
val uri = FileProviderUtils.getUriForFile(this, imageFile)
takePicture(uri) {
    Log.d(TAG, "takePicture it=$it, imageUri=$imageUri, uri=$uri")
}

takeVideo 调用系统相机拍照

val videoFile = File(getExternalFilesDir("image"), "temp.mp4")
val uri = FileProviderUtils.getUriForFile(applicationContext, videoFile)
takeVideo(uri) {
    // ... 
}

其他

还有TakePicturePreview、OpenDocument、PickContact等如有需要可以添加，具体见ActivityResultContracts
