buttonbar

I want to obtain a similar tab effect with the button bar of twitter app. I wish to click on a button and change the view down. I can switch activity but I think It's wrong, or not? The top bar have to be fix like a frame. Like this: Ok now I post a part of my idea (i found something similar here: http://www.talkandroid.com/android-forums/android-development-answers-tutorials-code-snippets/1515-how-i-open-image-imagebutton.html ) code: newsButton = (ImageButton) findViewById(R.id.news); newsButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // on

I have a listview which is part of an Activity. I want user to have a choice for batch deleting the items in the listview, so when he chooses the corresponding option from the menu, every list item gets a checkbox next to it. When user clicks any checkbox, a button bar is to slide up from bottom (as in gmail app) and clicking delete button deletes the selected items, however clicking cancel button on the bar would uncheck all the checked items. This is my page layout.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android
