解决方案
这是最好的，我可以做本机API，似乎时机是不完全正确，因为网页和动画的加载是异步的..编辑：更新了，这个人是略好。 EDIT2：这是我最好的尝试，到目前为止，它允许用户认识到页面加载..获得半流畅的动画效果的唯一方法是让该页面以preLOAD，而用户不看看吧。

If anyone can help me with this I will be very happy. I have an application that uses webview. The webview loads a url and I have used the Google tutorial to overide all the other links that I want to open with webview also. I have create an animimation file in res/ and a slide_right xml and so far so good. I call the effect in my main java activity but it only applies to the first page. The thing that I want is the effect to apply in every page that links loads in webview.
Can you help my with my code?

}
}
@Override

mWebView.setWebViewClient(new HelloWebViewClient());
解决方案
This is the best I could do with the native apis, it seems the timing isn't quite right because the loading of the page and animation are asynchronous.. EDIT: updated, this one is marginally better. EDIT2: This is my best attempt so far, and it allows the user to realize that the page is loading.. The only way to get a semi-smooth animation is to allow the page to preload, while the user does not see it.
package com.adeptdev.animwebview;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class HelloWebViewActivity extends Activity {
ProgressDialog mProgressDialog;
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.setVisibility(View.GONE);
mProgressDialog.setTitle("Loading");
mProgressDialog.show();
mProgressDialog.setMessage("Loading " + url);
return false;
}
@Override
public void onPageFinished(WebView view, String url) {
mProgressDialog.dismiss();
animate(view);
view.setVisibility(View.VISIBLE);
super.onPageFinished(view, url);
}
}
private void animate(final WebView view) {
Animation anim = AnimationUtils.loadAnimation(getBaseContext(),
android.R.anim.slide_in_left);
view.startAnimation(anim);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
WebView view = (WebView) findViewById(R.id.webview);
if ((keyCode == KeyEvent.KEYCODE_BACK) && view.canGoBack()) {
view.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mProgressDialog = new ProgressDialog(this);
WebView webView = (WebView) findViewById(R.id.webview);
webView.setVerticalScrollBarEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com/");
webView.setWebViewClient(new HelloWebViewClient());
}
