Question

Answer 1

I wanna share my code on how to use the android-zoom-view.jar. This is how I use it.

1. Create a new layout (R.layout.zoomable_view) for Views that i want to apply the zooming functionality.
2. Place it inside ZoomView.

3. Then place the ZoomView to the main container where you want to show the zoomable view.

   private ZoomView zoomView;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_zoomable);
   
      View v = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.zoomable_view, null, false);
      v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
   
      zoomView = new ZoomView(this);
      zoomView.addView(v);
   
      main_container = (LinearLayout) findViewById(R.id.main_container);
      main_container.addView(zoomView);            
   }
   

I hope this will help others.

When looking at the project, you can assume that it is not used (very) much. Therefore, looking for official documentation (no Javadoc is used in the source...) or tutorials seems pointless.

So you have to do it yourself, so check out the only java source file the project has, it does not look to difficult to use:

• Notice that the class extends the FrameLayout class, so you can assume it will behave as a regular FrameLayout. So check out FrameLayout related tutorials.
• Focus on the public methods, as it defines the 'API' of the Zoomlayout
