Question

有类似的问题，但我是一个新手并且因为每个人都有不同的编码风格而感到困惑...我想要一个进度条显示在'Splash Screen'后面而不是白屏10秒钟每次点击一个链接......

我怎么会这样实现，因为我不知道？我没有使用webchromeclient或任何其他东西。还在学习。这是我的代码;

XML中的ProgressBar;

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="23dp"
    android:layout_marginTop="20dp"
    android:indeterminate="false"
    android:max="100"
    android:minHeight="50dp"
    android:minWidth="200dp"
    android:progress="1" />

我的Java代码;

public class SecondActivity extends Activity {

 private WebView myWebView;
 private ProgressBar progressBar;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.secondlayout);
    String url = "http://ythaber.com/";

    myWebView = (WebView) this.findViewById(R.id.webView1);
    progressBar = (ProgressBar) findViewById(R.id.progressBar1);

    myWebView.setWebViewClient(new WebViewClient());
    myWebView.getSettings().setJavaScriptEnabled(true);
    myWebView.loadUrl(url);
    myWebView.getSettings().setLoadsImagesAutomatically(true);

}

@Override
// Detect when the back button is pressed
public void onBackPressed() {
    if (myWebView.canGoBack())
        myWebView.goBack();
    else if (myWebView.canGoForward())
        myWebView.goForward();
    }
}

谢谢，DG

实施如下：的的onCreate（）

@Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.web_view); web_view = (WebView) findViewById(R.id.web_view); pd = new ProgressDialog(Activity.this); pd.setMessage("Please wait Loading..."); pd.show(); web_view.setWebViewClient(new MyWebViewClient()); web_view.setWebViewClient(new WebViewClient()); web_view.getSettings().setJavaScriptEnabled(true); web_view.getSettings().setLoadsImagesAutomatically(true); web_view.loadUrl("ur site name"); }

<强> WebViewClient

private class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); if (!pd.isShowing()) { pd.show(); } return true; } @Override public void onPageFinished(WebView view, String url) { System.out.println("on finish"); if (pd.isShowing()) { pd.dismiss(); } }

将ProgressBar添加到Webview中 - Android
