Saving and Reloading ListView using Shared Preferences [Saving onDestroy()]


Tag : android , By : Sandeep Arneja

I hope this helps you . Android SharedPreferences is used to store a single key-value paired data. In other words, it is not made to store repetitive and complex data. In your case, a list view may contain than 100 rows or more depends on your app. If you were to create a SharedPreferences object for each row it would be 100+ of it, which is not efficient at all. The solution for this is as suggested above, is to use the Android's SQLite database.
A good tutorial: http://www.androidhive.info/2011/11/android-sqlite-database-tutorial/

How to set d3.layout.force.charge once d3.layout.force has already been initialized?

Hope this helps all you have to do is call force.start which runs through the declared nodes again and changes the charges and other properties on them.
svg.on("click", function() {
  force = force.charge(function(d, i) { return i ? 0 : -50000; })
  force.start()
  window.setTimeout(function() {
  force = force.charge(function(d, i) { return i ? 0 : -2000; })
  force.start()
  },3000);
});

Force layout inside force layout: How to drag inner nodes

To fix this issue When you drag the inner circle, you are also dispatching drag events to the outer nodes (because they are overlapped). To prevent this, you need to use d3.event.stopPropagation() for your drag behviour.
var innerAnodes = aNode.selectAll("g.inner")
  .data(innerAdata, function (d) {return d.id;})
  .enter()
  .append("g")
  .attr("class", "inner")
  .attr("id", function (d) {return d.id;})
  .call(innerAlayout.drag()
        .on("dragstart", function(){            
            d3.event.sourceEvent.stopPropagation();
        })
       );

I wish this helpful for you I am using Sticky Force Layout. My code with initial tickling can be seen here. I have followed the Fisheye distortion code that having static layout. But I am not getting the expected output. My code is here. , Set the cooling parameter alpha to 0 or less:
var force = d3.layout.force()
                .linkDistance(75)
                .alpha(0)
                .size([width, height])
                .on("tick", tick);
function tick() {
 var k = 0;
 while ((force.alpha() > 1e-2) && (k < 150)) {
    force.tick();
    k = k + 1;
 }
 node.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; });
 }
