当我尝试在 webView 上发布 URL 前 3-4 秒时,我得到白屏,然后浏览器打开。如果我按下回只有白屏来。如果我再次按下,那么只有它来活动。所以我将如何删除这个白色屏幕。这是我的代码。
import org.apache.http.util.EncodingUtils;
import com.google.analytics.tracking.android.EasyTracker;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

import android.webkit.WebView;
public class HtmlViewerActivity extends Activity {
WebView wv;
String payUrl;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.web_viewer);
wv = (WebView) findViewById(R.id.webid);
// use cookies to remember a logged in status
CookieSyncManager.createInstance(this);
CookieSyncManager.getInstance().startSync();
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
// getting data from other Activity using bundle
Bundle bundle = new Bundle();
bundle = getIntent().getExtras();
payUrl = bundle.getString("payUrl");
wv.setKeepScreenOn(true);
wv.getSettings().setDomStorageEnabled(true);
wv.getSettings().setBuiltInZoomControls(true);
byte[] post = EncodingUtils.getBytes(payUrl, "BASE64");
wv.postUrl("http://syntheverest.collasapp/app/get_details.php", post);
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
if (wv.canGoBack())
wv.goBack();
else
super.onBackPressed();
}
}
