how to set a button to mimic another button's backgroundresource

I want to know how I could change a buttons backgroundresource that mimics another button's background resource so that whenever I change that button's backgroundresource it another button mimics the looks of the first button...
for example:
int icon = R.drawable.ic_icon; //more specifically I stored R.drawable.ic_icon in SQL and retrieve and save in int icon when retrieve from that table, so when the table is change the first button dynamically change on create;
btn_01.setBackgroundResource(icon); //when this button is pressed it inflates a layout containing btn_02
btn_02.setBackgrounResource(??????); //this button is on a different layout and is used by different activity and should take the backgroundresource of the button that have been pressed to call that layout.
I could use if else statement but I have different button to be copied by the second button and each button has different backgroundresource possibility.

I couldn't understand your question fully but anyways here is what I got
You can put the resource id in the Intent before starting the activity when Btn_01 is clicked.
Btn_01.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(this,Activity2.class);
intent.putExtra("resource_key", R.drawable.ic_heart);
startActivity(intent);
}
});
then in your Activity2 you can just get your resource data and set to whatever button you want
int DEFAULT_RESOURCE = R.drawable.ic_close;
int resourceId = getIntent().getIntExtra("resource_key",DEFAULT_RESOURCE);
Btn_02.setBackgroundResource(resourceId);

ImageView and swapping images

I want to create simply application where user can review some pictures. In list I have some pictures and I want to show next pictures after click button. So this is the way: user start application and after click on the button, previous picture is replaced by next picture from the list. I want to use ImageView to show pictures. Can anyone help me?
I tried:
ImageView img = (ImageView)findViewById(R.id.image);
img.setImageResource(picturelist.get(pictureLeft));
where picturelist is list with pictures, and pictureLeft is int variable represents my index. To my list I add elements by:
picturelist.add(R.drawable.car);

do something like this:
yourButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v)
{
if(pictureLeft < picturelist.size())
{
img.setImageResource(picturelist.get(pictureLeft));
pictureLeft++;
}
}
});

In Android: How do you show layout twice using intent?

Let's pretend this was my Java Class...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button ScreentwoGameButton = (Button) findViewById(R.id.screentwo);
ScreentwoGameButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent ScreentwoGameIntent = new Intent(Main.this, Screentwo.class);
startActivity(StartGameIntent);
}
});
How do i use this code below but the right way like.
So let's put an example if I click screentwo button the screentwo.xml will show and it will allow me to click inside if any buttons are available. Instead just stare what's in the layout.
I don't want to use the Activity to activity cause the whole point is i'm trying to avoid the flashing looking feel going to another java class.
If you look at the moron test game on Android it says example: press the blue button then red and then green, so if u press the blue button the screen will remain and not flash at all but the image of the blue button will disappear and I'm allowed to click the red and then green.
Hope that helped.
Thanks

Button ScreentwoButton = (Button) findViewById(R.id.screentwo);
ScreentwoButton.setOnClickListener(new OnClickListener() {
private Uri Uri;
#Override
public void onClick(View v) {
setContentView(R.layout.Screentwo);
Uri uri=Uri;
Intent i=new Intent(Intent.ACTION_VIEW, uri);
mSoundManager.playSound(1);
}
});

try to use:
setContentView(R.layout.next layout); in your button click.

You could use the viewflipper class and add the different layouts as childs to the viewflipper
and set the active child. Using setcontentView will be trouble some when you use findViewById for a old layout. As findViewById will look in the layout that is specified by setContentView

Layout in android

I have three buttons in one activity.when each of the button is clicked ,different layout should be shown with in the same activity.for example if first button is clicked,edit boxes and button should be shown.if second buttojn is clicked listview should be shown etc..

Define different layout files for each layout.
Then after each click event have the intent call this particular activity recalled.
Have setContentView() called conditionally ie determining the particular clickevent and vice versa.
This you can do if you want complete activity to be layuot in diffrent manner. Otherwise if you want some widgets to be displayed on button click then it is pretty easy to show them on click event.

You might wanna consider a "TabWidget" for this. It actually does what you need.
A sample tutorial here.

Why don't you just include the all the layout elements in your single layout, then use the setVisibility attribute to turn them on and off, depending on which button is pressed.
Something like this pseudo code:
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
view1.setVisibility(View.GONE);
view2.setVisibility(View.GONE);
view2.setVisibility(View.VISIBLE);
}
});
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
view1.setVisibility(View.VISIBLE);
view2.setVisibility(View.GONE);
view2.setVisibility(View.GONE);
}
});

Displaying ImageButtons in an Activity

I want to display ImageButtons like in an activity in my android application.
Now when i click on any one of the ImageButton, it should start a new Activity.
I don't know whether this type of view is possible or not. ?

You should check the Gallery widget.

yah that's possible.like an button clck listener there is also a listener for the image button .by that calling the another activity a

You can try the below code:-
ImageButton imageButton = new ImageButton(getApplicationContext());
imageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent("<activity_class_name or intent action");
context.startActivity(intent);
}
});
