我不确定我是否正确理解了你的意思。但是如果你想请求屏幕录制的许可，这将是正确的方法（从API 30开始）：

ActivityResultLauncher<Intent> launcher = registerForActivityResult(
  new ActivityResultContracts.StartActivityForResult(),
  new ActivityResultCallback<ActivityResult>() {
    @Override public void onActivityResult(ActivityResult result) {
      if (result.getResultCode() == RESULT_OK) {
        // your code, e.g. start a new activity
      } else {
        // no permission given, finish your app
      }
    }
  }
);
MediaProjectionManager mediaProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
Intent myIntent = new Intent(mediaProjectionManager.createScreenCaptureIntent());
launcher.launch(myIntent);
