javascriptからいくつかの値を受け取るためのjavascriptインターフェースクラスがあります。インターフェイス クラスからその値をトーストしましたが、その値を TextVie に設定することはできません。何が問題になりますか??
class JavaScriptInterfaceForCount {
Context mContext;
JavaScriptInterfaceForCount(Context c) {
mContext = c;
}
public void receiveValueFromJs(String scrollwidth, String columwidth) {
mPagenumberTextView.setText(scrollwidth+"");
}
}
