5min Android Hack #3: Catch URLs in WebView

How to intercept loading URLs inside your WebView.

• Let's assume you have a WebView available in your activity, like this:

  mWebView = (WebView) findViewById( R.id.mywebview);

  
  
• Now you can override the shouldOverrideUrlLoading method like this:
  

  mWebView.setWebViewClient(new WebViewClient(){
      @Override public boolean shouldOverrideUrlLoading(WebView view,
                                            String url) 
      {
  

  ...
  
• That's it. Each time a link is clicked on your WebView, it will call your shouldOverrideUrlLoading method. The method should return true if the URL was acted upon, or false otherwise.

5min Android Hack #1: Set Background Image

How to set a background image on a view on Android.

• Add an image, preferably a PNG, to the "res/drawable" folder.
• Open the XML file for the respective UI component, and add this to the element you want to set the background image for:

  android:background="@drawable/<your image>

  You can omit the file extension. The @drawable part in the reference to the image tells Android to take the image from your res/drawable folder.
