我的网页浏览不适用于重定向到其他网页的网址.它从应用程序打开浏览器,但不加载webview.任何的想法？
webview的代码是：
webView = (WebView) findViewById(R.id.simpleWebView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
if(getIntent().getStringExtra("url")!=null){
loadLink(getIntent().getStringExtra("url"));
}else{
Toast.makeText(WebViewActivity.this,"Please try again later!",Toast.LENGTH_SHORT).show();
finish();
}
解决方法
主类
public class Main extends Activity {
private WebView webview;
private static final String TAG = "Main";
private ProgressDialog progressBar;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
this.webview = (WebView)findViewById(R.id.webview);
WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
progressBar = ProgressDialog.show(Main.this,"WebView Example","Loading...");
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view,String url) {
Log.i(TAG,"Processing webview url click...");
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view,"Finished loading URL: " +url);
if (progressBar.isShowing()) {
progressBar.dismiss();
}
}
public void onReceivedError(WebView view,int errorCode,String description,String failingUrl) {
Log.e(TAG,"Error: " + description);
Toast.makeText(activity,"Oh no! " + description,Toast.LENGTH_SHORT).show();
alertDialog.setTitle("Error");
alertDialog.setMessage(description);
alertDialog.setButton("OK",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
return;
}
});
alertDialog.show();
}
});
webview.loadUrl("http://www.google.com");
}
}
你的main.xml布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView android:id="@string/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" />
</LinearLayout>
