こんにちは、Android アプリケーションを開発しています。すべての itel が webview に URL を表示するリスト項目があります。しかし、webview で YouTube ビデオを開くと、表示できません。

これは私のアクティビティコードです

このplsの解決策を持っている人は、それについて教えてください

を追加webview.setWebChromeClient(new WebChromeClient());して、ビデオのプラグインを有効にするには、次のように追加します。

if (Build.VERSION.SDK_INT < 8) {
        webview.getSettings().setPluginsEnabled(true);
    } else {
        webview.getSettings().setPluginState(PluginState.ON);
    }

これは私のために働いた.これが役立つことを願っています.
