android - スライド メニュー - 右から左へ

Question

以下の例のスライドメニューを試していました。

https://github.com/eddieringle/android-undergarment

しかし、これには左から右へのスライド実装があります。これを右から左に変更するにはどうすればよいですか。誰でもこれを理解するのを手伝ってもらえますか?

Answer 1

私はあなたがあなたの答えを得ることを知っていますが、外部ライブラリを使用したくない場合は、これを使用できます:

このコードはgitHubに存在します

しかし、このプロジェクトは左右のメニューに使用され、少し変更して右から左に開くことができます。コードを変更してコピーします。次のコードを使用すると、両方のサイド メニューを表示できます。
