问题与进度条在web中的Web视图

Question

我已经开发了一个具有一个Web视图和一个进度条的应用程序,所以我想在加载网页的进度条中添加显示进度等功能,以便它如何实现我有我放在这里的代码.

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        web = (WebView) findViewById(R.id.web);
        progressBar = (ProgressBar) findViewById(R.id.progrss);

        web.setWebViewClient(new myWebClient());
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("http://www.technotalkative.com");
    }

    public class myWebClient extends WebViewClient {



        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }
        @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    // TODO Auto-generated method stub

                    view.loadUrl(url);
                    return true;

                }
        @Override
                public void onPageFinished(WebView view, String url) {
                    // TODO Auto-generated method stub
                    super.onPageFinished(view, url);

                    progressBar.setVisibility(View.GONE);
                }
    }


}


layout file..

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:orientation="vertical" >

     <ProgressBar 
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_gravity="center"
        android:id="@+id/progrss"
        style="?android:attr/progressBarStyleHorizontal"
        android:progressDrawable="@drawable/blue_progressbar"

        />      

    <WebView
        android:id="@+id/web"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_weight="1">
    </WebView>



 </LinearLayout>

Answer 1

准备好你 progress bar喜欢

 progressBar.setProgress(0);
 probressbar.setMax(100);

你应该intermediate progress使用

progressBar.setProgress(int);

并实现你WebViewClient喜欢这样:

web.setWebViewClient(new myWebClient());
//add this below line
web.setWebChromeClient(new WebChromeClient() {
 public void onProgressChanged(WebView view, int progress) {
    progressBar.setProgress(progress);

 if (progresss == 100) {
 progressBar.setVisibility(View.GONE);

 } else{
 progressBar.setVisibility(View.VISIBLE);

 }
 }
});
