java-即使网页完成加载后,webview中的进度条仍保持加载

概述这是我的代码importandroid.annotation.SuppressLint;importandroid.content.Intent;importandroid.graphics.Bitmap;importandroid.net.Uri;importandroid.support.v7.app.ActionBarActivity;importandroid.os.Bundle;importandroid.view.Menu;importandroid.vie

这是我的代码

import androID.annotation.Suppresslint;import androID.content.Intent;import androID.graphics.Bitmap;import androID.net.Uri;import androID.support.v7.app.ActionBaractivity;import androID.os.Bundle;import androID.vIEw.Menu;import androID.vIEw.MenuItem;import androID.vIEw.VIEw;import androID.webkit.WebVIEw;import androID.webkit.WebVIEwClIEnt;import androID.Widget.Progressbar;@Suppresslint("SetJavaScriptEnabled")public class MainActivity extends ActionBaractivity {private WebVIEw vIEw;private Progressbar progressbar;@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    progressbar = (Progressbar) this.findVIEwByID(R.ID.progressbar);    String url = "http://www.carsaleindiaofficial.com/?m=1";    vIEw = (WebVIEw) this.findVIEwByID(R.ID.webVIEw);    vIEw.setWebVIEwClIEnt(new WebVIEwClIEnt());    vIEw.getSettings().setJavaScriptEnabled(true);    vIEw.getSettings().setDomStorageEnabled(true);    vIEw.loadUrl(url);}public class MyAppWebVIEwClIEnt extends WebVIEwClIEnt {    @OverrIDe    public voID onPageFinished(WebVIEw vIEw, String url) {        super.onPageFinished(vIEw, url);        vIEw.findVIEwByID(R.ID.progressbar).setVisibility(VIEw.GONE);        //if (progressbar.getVisibility() == VIEw.VISIBLE)        //progressbar.setVisibility(VIEw.INVISIBLE);        //progressbar.setVisibility(VIEw.INVISIBLE);        //progressbar.setVisibility(VIEw.GONE);    }    @OverrIDe    public voID onPageStarted(WebVIEw vIEw, String url, Bitmap favicon) {        super.onPageStarted(vIEw, url, favicon);    }    @OverrIDe    public boolean shouldOverrIDeUrlLoading(WebVIEw vIEw, String url) {        if (Uri.parse(url).getHost().endsWith("carsaleindiaofficial.com/?m=1")) {            return false;        }        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));        vIEw.getContext().startActivity(intent);        return true;    }}@OverrIDepublic voID onBackpressed() {    if (vIEw.canGoBack()) {        vIEw.goBack();    } else {        super.onBackpressed();    }}@OverrIDepublic boolean onCreateOptionsMenu(Menu menu) {    getMenuInflater().inflate(R.menu.menu_main, menu);    return true;}@OverrIDepublic boolean onoptionsItemSelected(MenuItem item) {    int ID = item.getItemID();    if (ID == R.ID.action_settings)        vIEw.loadUrl(vIEw.getUrl());    return super.onoptionsItemSelected(item);    }}

进度条和WebvIEw可以正常工作,但是在页面加载完成后,进度条仍然存在吗？加载页面后,进度条的可见性不会消失/变为GONE吗？错误在哪里？
我已经尝试了progressbar.setVisibility(VIEw.INVISIBLE)和progressbar.setVisibility(VIEw.GONE);但没什么似乎起作用.

解决方法:

而不是使用自定义webclIEnt.您使用默认的webclIEnt.您的问题是替换它.

vIEw.setWebVIEwClIEnt(new WebVIEwClIEnt()); 

加上这个

vIEw.setWebVIEwClIEnt(new MyAppWebVIEwClIEnt());

并且

 progressbar.setVisibility(VIEw.INVISIBLE);

不

vIEw.findVIEwByID(R.ID.progressbar1).setVisibility(VIEw.GONE);
