Add Loading Indicator/progress Bar To Phonegap Android Splashscreen

August 02, 2023 Post a Comment

I have a PhoneGap 1.4.1 / jQueryMobile 1.0.1 / Android project which is showing the res/drawable/splash.png just fine, and the splashscreen goes away once the WebView is loaded. I

Solution 1:

I think I've found a solution (not a full solution, but a spinner solution). Inside DroidGap subclass you should add this line:

super.setStringProperty("loadingDialog", "Wait, Loading...");

Here is my full example

publicclassMainActivityextendsDroidGap {
    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        super.setIntegerProperty("splashscreen", R.drawable.splash);
        // Display a native loading dialog.  Format for value = "Title,Message".  // (String - default=null)super.setStringProperty("loadingDialog", "Wait,Loading Demo...");

       super.loadUrl("file:///android_asset/www/index.html");
      }
}

There are several properties you could set up in this section, please see this code: https://svn.apache.org/repos/asf/incubator/callback/phonegap-android/branches/WebSockets/framework/src/com/phonegap/DroidGap.java

I finally managed to add a progress bar to a PhoneGap webView which will show the progress (percentage) of the page load. Hope this helps you

As this other answer explains, appView is located inside a LinearLayout. The protected (and therefore inherited) variable root references this LinearLayout. You can add your (whatever) native Views to this variable.

Here is how I did:

Create a layout in your res/layouts/

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical" ><ProgressBarandroid:id="@+id/progressBar1"style="@android:style/Widget.ProgressBar.Horizontal"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_alignParentBottom="true"android:layout_alignParentLeft="true"android:layout_alignParentRight="true"android:maxHeight="10dip"android:minHeight="10dip" /></LinearLayout>

Follow all the steps you would normally follow for adding a WebView progress bar:
```
finalActivityactivity=this;
private ProgressBar progessBar1;
```
Add the layout you created:
```
Viewfooter= View.inflate(getContext(), R.layout.mainshop, null);
root.addView(footer);
```
If you add it after calling super.loadURL(...); it will be displayed at the bottom. If you add it before, the layout will be displayed before the appView.

After that you simply add this:

progessBar1 = (ProgressBar) findViewById(R.id.progressBar1);

this.appView.setWebChromeClient(new WebChromeClient() {

        publicvoidonProgressChanged(WebView view, int progress) { 
            activity.setProgress(progress * 1000);
            if(progress < 100 && progessBar1.getVisibility() == ProgressBar.GONE) {
                progessBar1.setVisibility(ProgressBar.VISIBLE);
            }
            progessBar1.setProgress(progress);
            if(progress == 100) {
                progessBar1.setVisibility(ProgressBar.GONE);
            }

            Log.d("Progress", progress+"");

         }
    });

Cheers!

I know you can easily add a loading indicator to your splash screen by setting the ShowSplashScreenSpinner option to YES in your PhoneGap configuration file (PhoneGap.plist on iOS)

It shows a spinner in the middle of the splash screen while the app is loading

Edit: This only works with iOS.

Solution 4:

Stop using a Activity that extends DroidGap, create a regular Android activity and put org.apache.cordova.CordovaWebView in a layout file. It will give you much more flexibility.

Solution 5:

If you use jquery-mobile you can do:

$.mobile.showPageLoadingMsg();
$('.ui-loader h1').html('<h1>Saving ... <span id="ui-loading-extra"></span>');

Then in onProgressChanged do:

$('#ui-loading-extra').text(progress  + '%');
