これが正しい方法かどうかはまったくわかりませんが、Webビューが読み込まれている限り、スプラッシュスクリーンを表示しています。Webビューの読み込みが完了すると、Webビューが表示されます。

しかし、WebビューのHTMLコンテンツが正しくレンダリングされていません。それは私のAndroid携帯電話の内蔵ブラウザと私が持っている他のすべてのデバイスでコンテンツを正しく表示します。したがって、問題はこのアプリに限定されます。

public final boolean networkCheck() {
    ConnectivityManager connec =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);

    if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||
    connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTING ||

Web サイトに JavaScript が含まれている場合、次の行がありません。

webView.getSettings().setJavaScriptEnabled(true);

ターゲットが 2.3.3 よりも高い場合は、これをマニフェスト ファイルに追加してみてください。

android:hardwareAccelerated="true"
