我的 webview 有问题,因为它有时会加载内容,有时不会。
我注意到 2.2 和 2.3.3 的 Android 版本没有问题,只有 4.0.4 的 Android 版本。
我的代码是:
public class MywebviewActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
    setContentView(R.layout.mywebview);
    final Activity MywebviewActivity = this;        
      // Makes Progress bar Visible
      getWindow().setFeatureInt(Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
      android.webkit.WebView wv = 
      (android.webkit.WebView)this.findViewById(R.id.myWebView); 
      wv.setWebChromeClient(new WebChromeClient() {     
      public void onProgressChanged(WebView view, int progress)   
      {
       //Make the bar disappear after URL is loaded, and changes string to Loading...
          MywebviewActivity.setTitle("Loading...");
          MywebviewActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded
      // Return the app name after finish loading
      if(progress == 100)
          MywebviewActivity.setTitle(R.string.web_app_name);
        }
  });
      wv.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
      wv.getSettings().setJavaScriptEnabled(true);
      wv.setHorizontalScrollBarEnabled(false);
      wv.loadUrl("http://mypagename.com/android/server/app/ver10/page1.html");
    }
public void onBackPressed() {
    android.os.Process.killProcess(android.os.Process.myPid());
    return;
}
