안드로이드 WebView에 Progress바 달기 두번째 예제 따라하기

-WebView를 이용할때 얼마나 페이지가 넘어가는지를 확인 할 수 있게 Progress바를 달아보자.
-이 예제를 통해 하이브리드 App을 구현해 보자.

-Java 소스

public class WebViewActivity extends Activity {

WebView mWeb;

ProgressBar progressBar;

String site;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

getWindow().requestFeature(Window.FEATURE_PROGRESS); // 프로그레스

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

site = "http://www.google.com";

mWeb = (WebView) findViewById(R.id.web1);

progressBar = (ProgressBar) this.findViewById(R.id.pro);

// mWeb.setWebViewClient(new WebViewClient());

WebSettings set = mWeb.getSettings();

set.setJavaScriptEnabled(true);

set.setBuiltInZoomControls(true);

mWeb.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

mWeb.setWebViewClient(new WebViewClient() {

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true;

};

public void onPageStarted(WebView view, String url,

android.graphics.Bitmap favicon) {

super.onPageStarted(view, url, favicon);

progressBar.setVisibility(View.VISIBLE);

};

public void onPageFinished(WebView view, String url) {

super.onPageFinished(view, url);

progressBar.setVisibility(View.INVISIBLE);

};

public void onReceivedError(WebView view, int errorCode,

String description, String failingUrl) {

super.onReceivedError(view, errorCode, description, failingUrl);

Toast.makeText(WebViewActivity.this, "로딩오류" + description,

Toast.LENGTH_SHORT).show();

};

});

mWeb.setWebChromeClient(new WebChromeClient() {

@Override

public void onProgressChanged(WebView view, int newProgress) {

progressBar.setProgress(newProgress);

}

});

mWeb.loadUrl(site);

}

}
