XML splash screen & # 8594; Show web view

Thanks for trying to solve my problem!

My app is currently loading a webpage using an Android webview. The disadvantage is that sometimes (with a bad connection) a web page takes more than 10 seconds to load. Is there a way to create some kind of XML splatter loading screen when loading a web page?

Take a look at my code ...

package com.ect;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.CookieSyncManager;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class SomeActivity extends Activity {

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

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //THIS IS WHAT I WANT: setContentView(R.layout.main);

        CookieSyncManager.createInstance(getBaseContext());

        // Let display the progress in the activity title bar, like the
        // browser app does.


        getWindow().requestFeature(Window.FEATURE_PROGRESS);

        WebView webview = new WebView(this);
        setContentView(webview);


        webview.getSettings().setJavaScriptEnabled(true);

        final Activity activity = this;
        webview.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);
        }
      });

webview.setWebViewClient(new WebViewClient() {

public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        //Users will be notified in case there an error (i.e. no internet connection)
        Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}

public void onPageFinished(WebView view, String url) {
    CookieSyncManager.getInstance().sync();
}
});

CookieSyncManager.getInstance().startSync();
CookieSyncManager.getInstance().sync();

     //This will load the webpage that we want to see
      webview.loadUrl("http://www.web.com/");

   }
}

This is my code. If you look closely, I made a comment that says: "THIS IS WHAT I WANT: ..."

This comment will cause the main.xml file to be displayed, but if I use this comment, the main.xml file will be displayed, but the webview will never appear ...

How can I display the main.xml file and then (after loading the web view) display the web page?

You should use the onPageFinished () event.

Here is the official Clickme link

Your main action is to setContentView (R.layout.main); and the onPageFinished () function should setContentView (webview);

You can do something like this: in your layout, the root layout (or relative layout) do something like this.

<Framelayout android:layout_height="fill_parent" android:layout_width="fill_parent"
....>

    <Webview android:layout_height="fill_parent" android:layout_width="fill_parent"/>

    <include android:layout_height="fill_parent" android:layout_width="fill_parent"  
    layout="@loadingLayout"/>

</Framelayout>

When the webview completes the download, just change the visibility of the incoming components to Gone.

Hope this helps.
