public class CommonIntentContract extends ActivityResultContract<Intent, Intent> {
    @NonNull
    @Override
    public Intent createIntent(@NonNull Context context, Intent input) {
        return input;
    }

    @Override
    public Intent parseResult(int resultCode, @Nullable Intent intent) {
        return intent;
    }
}

// 开启下一页 传入Intent
launcher.launch(new Intent(this, MActivity.class)
        .putExtra(StaticGather.DATA, "abc"));
