平安あれ。

私は Web ビュー アプリで作業しており、JavaScript を介してアクティビティを変更したいと考えています。

まず、WebView に JavascriptInterface を追加しました。

wv.addJavascriptInterface(new JsInterface(this), "android");

そして、これはクラスです:

public class JsInterface{
    private Activity mContext;

    JsInterface(Activity c) {
        mContext = c;
    }

     public void changeVisibility(){
         wv = (WebView) mContext.findViewById(R.id.wv);
         wv.setVisibility(View.GONE);
     }

}

JavaScript が android.changeVisibility() を呼び出すと、アプリがクラッシュします。

アクティビティクラスにwvをセットしました

WebView wv;

また、JavaScript を介してアクティビティ内の別のビュー ( Buttons や EditTexts など) を変更できますか?

私の悪い英語でごめんなさい。

以下のようにする必要があります。

public void changeVisibility(){

             Thread _trd1 = new Thread() {
                    public void run() {
                        runOnUiThread(new Runnable() {
                        public void run() {
                            wv.setVisibility(View.GONE);
                        }
                });
                    }
              };

             _trd1.start();

         }
