我正在为一个Web视图应用程序工作，并希望通过JavaScript更改活动。
首先，我为我的WebView添加了一个JavascriptInterface：
wv.addJavascriptInterface(new JsInterface(this), "android");
这是班级：
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);
}
}
当JavaScript调用android.changeVisibility（）时，我的应用程序崩溃了。
在活动类
中设置了wvWebView wv;
我可以通过JavaScript更改活动中的任何其他视图（例如Buttons和EditTexts）吗？
抱歉我的英语不好。

你应该这样做：
public void changeVisibility(){
Thread _trd1 = new Thread() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {
wv.setVisibility(View.GONE);
}
});
}
};
_trd1.start();
}
