Android: Use icon as back button without reloading previous activity

Question

I have the following code to enable to home button to act as a back button. The problem I'm facing is from this activity if I use the real back button it simply goes back to the previous activity just as I left it. If I use the home button it's reloading the page so I lose what was previously done to it. I'm sure it's something simple I'm missing.

@Override
public boolean onCreateOptionsMenu(Menu menu) 
{
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.census_management_search, menu);
    ActionBar actionBar = getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) 
{
    // Handle item selection
    switch (item.getItemId()) 
    {
        case android.R.id.home:
            Intent intent = new Intent(this, CensusManagementActivity.class);
            NavUtils.navigateUpTo(this, intent);
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

Answer 1

Instead of Intent and NavUtils try using onBackPressed() method.

@Override
public boolean onOptionsItemSelected(MenuItem item) 
{
    // Handle item selection
    switch (item.getItemId()) 
    {
        case android.R.id.home:
            onBackPressed();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}
