How To Manage Home Screen In Nexus 7 And JellyBean

October 6, 2013 by blogmeister·0 Comments

The short answer is, you cannot. I find it weird why Google did not include this option. The Nexus 7 home screen by default is set to 5 and I really have no need for so many screens.

Considering there are folders to help manage your apps, this option should never have been excluded unless Google did this on purpose to force users to spread out all app icons on the home screen then that would make folders have no use at all.

So anyway, if you really want to remove the other home screens, the only solution is to download some other launcher like Apex or Nova.

There are free versions of them and you can already manage the home screens with it. There is no need to purchase the pro or paid version in order to be able to manage home screens.

How To Remove Tab In JColorChooser

May 8, 2012 by blogmeister·0 Comments

There will come a time when you want only a selected tab to appear in the JColorChooser. As far as I know, there is no way to do this with Java‘s API. If there is, please leave a comment and share.

Here is an initial code that I found in Example Depot that removes the tabs:

JColorChooser chooser = new JColorChooser();
// Retrieve the current set of panels
AbstractColorChooserPanel[] oldPanels = chooser.getChooserPanels();
// Remove panels
for (int i=0; i<oldPanels.length; i++) {
    String clsName = oldPanels[i].getClass().getName();
    if (clsName.equals("javax.swing.colorchooser.DefaultSwatchChooserPanel")) {
        // Remove swatch chooser if desired
        chooser.removeChooserPanel(oldPanels[i]);
    } else if (clsName.equals("javax.swing.colorchooser.DefaultRGBChooserPanel")) {
        // Remove rgb chooser if desired
        chooser.removeChooserPanel(oldPanels[i]);
    } else if (clsName.equals("javax.swing.colorchooser.DefaultHSBChooserPanel")) {
        // Remove hsb chooser if desired
        chooser.removeChooserPanel(oldPanels[i]);
    }
}
JColorChooser.createDialog(null, "Dialog Title", false, chooser, null, null).setVisible(true);

JColorChooser chooser = new JColorChooser();

// Retrieve the current set of panels

AbstractColorChooserPanel[] oldPanels = chooser.getChooserPanels();

// Remove panels

for (int i=0; i<oldPanels.length; i++) {

String clsName = oldPanels[i].getClass().getName();

if (clsName.equals("javax.swing.colorchooser.DefaultSwatchChooserPanel")) {

// Remove swatch chooser if desired

chooser.removeChooserPanel(oldPanels[i]);

} else if (clsName.equals("javax.swing.colorchooser.DefaultRGBChooserPanel")) {

// Remove rgb chooser if desired

chooser.removeChooserPanel(oldPanels[i]);

} else if (clsName.equals("javax.swing.colorchooser.DefaultHSBChooserPanel")) {

// Remove hsb chooser if desired

chooser.removeChooserPanel(oldPanels[i]);

}

JColorChooser.createDialog(null, "Dialog Title", false, chooser, null, null).setVisible(true);

Just comment out the lines that call removeChooserPanel() method if you do not want those tabs to be removed.

Remove Android Notification After Tap Or Click

February 1, 2012 by blogmeister·0 Comments

I recently added a notification feature for my widget and what I wanted was whenever the user clicks or taps the notification message in the notification center, it will remove itself rather than having to click the clear all button.

The secret lies in the flags of the Notification class by using Notification.FLAG_AUTO_CANCEL. However, to ensure that this works, the code has to be bitwise-or the flags like this

Notification notification = new Notification(R.drawable.icon, "Title", "This is a message", System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;

1 2	Notification notification = new Notification(R.drawable.icon, "Title", "This is a message", System.currentTimeMillis()); notification.flags \|= Notification.FLAG_AUTO_CANCEL;

Pretty easy, right?
