Question

这里我想在加载另一个webview时加载Web视图我的代码是
其实我的主题我有两个选项，一个是谷歌和facebbok，同时打开应用程序谷歌将被加载，如果我们按fb按钮facebook将被加载，但这将是时间过程

为了避免那段时间我只想加载谷歌进行fb（只加载谷歌时我们必须在第二个网页视图中加载fb，它处于隐藏状态） 4.当用户选择fb时，我们必须在没有时间的情况下表明这一点。

public class MainActivity extends Activity {

Button google,fb;

RelativeLayout paremt;


@Override

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);


// adding webview before loading the ui design

getWindow().requestFeature(Window.FEATURE_PROGRESS);


setContentView(R.layout.activity_main);

final WebView wv=new WebView(MainActivity.this);
final WebView wv1=new WebView(MainActivity.this);

wv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
wv1.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
wv.getSettings().setJavaScriptEnabled(true);
wv1.setVisibility(View.INVISIBLE);
wv1.getSettings().setJavaScriptEnabled(true);



paremt=(RelativeLayout)findViewById(R.id.rel2);
 paremt.addView(wv);
//paremt.addView(wv1);

final Activity activity = this;
 wv.setWebChromeClient(new WebChromeClient() {
   public void onProgressChanged(WebView view, int progress) {
     // Activities and WebViews measure progress with different scales.
     // The progress meter will automatically disappear when we reach 100%
       System.out.println(" progress is  "+progress);

       //loading hidden webview with second link, while completion of second link

       if(progress==100)
       {
           wv1.loadUrl("https://www.facebook.com");
       }

     activity.setProgress(progress * 1000);
   }
 });
 wv.setWebViewClient(new WebViewClient() {
   public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
     Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
   }
 });

wv.loadUrl("https://www.google.com");

google=(Button)findViewById(R.id.button1);
fb=(Button)findViewById(R.id.button2);
int j=paremt.getChildCount();
System.out.println("aaaaaaaaaaaaaaaaaaaaa   "+j);
google.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        paremt.removeAllViews();
        paremt.addView(wv);
        wv.setVisibility(View.VISIBLE);

    }
});
fb.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        paremt.removeAllViews();
        wv1.setVisibility(View.VISIBLE);
        paremt.addView(wv1);
        wv1.setWebChromeClient(new WebChromeClient() {
               public void onProgressChanged(WebView view, int progress) {
                 // Activities and WebViews measure progress with different scales.
                 // The progress meter will automatically disappear when we reach 100%
                 activity.setProgress(progress * 1000);
               }
             });
             wv1.setWebViewClient(new WebViewClient() {
               public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                 Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
               }
             });

            //wv1.loadUrl("https://www.facebook.com");
    }
});

} }

Answer 1

wv.loadUrl("https://www.google.com");
wv1.loadUrl("https://www.facebook.com");

同时调用这些行并从onProgressChanged方法中删除facebook url的调用
