我想在我的应用中实现一个应用内浏览器。为了实现这一点,我在 AlertDialog.Builder 对象中使用了 WebView 并显示了它。
final AlertDialog.Builder alert = new AlertDialog.Builder(context);
现在我遇到了一个问题,我想让 AlertDialog.Builder 的标题显示加载页面的进度,所以我重写了 onProgressChanged 函数并尝试重置标题如下:
wv.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
alert.setTitle("Loading..." + progress + "%");
tv.setText("Loading..." + progress + "%");
view.setVisibility(View.GONE);
if (progress == 100) {
alert.setTitle(title);// THIS DOES NOT HAVE ANY EFFECT
tv.setVisibility(View.GONE);//THIS IS "LOADING..." string, That I have written as make shift for the time being
view.setVisibility(View.VISIBLE);//This displays the WebView when it if loaded.
}
}
});
我希望 AlertDialog.Builder 标题动态更改。
