Use two components from different layouts - eclipse

Question

I have 2 layouts,in first layout I have EditText,Button and in second layout I have TextView. What I want is when i write something in EditText to copy that in second layout when you press button,but i get crash every time. Is there any way to use components from two layouts or i am missing something. If this is imposible another way would be good. Thx
main activity
public void onCreate(Bundle ivansad) {
super.onCreate(ivansad);
setContentView(R.layout.activity_main);
Button Start = (Button) findViewById(R.id.bStart);
Start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
setContentView(R.layout.numbers);
Intent Changeto2 = new Intent (MainAct.this, Numgen.class);
startActivity(Changeto2);
}
});
}
second activity
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.numbers);
Button Next = (Button)findViewById(R.id.bNext);
final EditText text = (EditText)findViewById(R.id.broj1);
final TextView edit = (TextView)findViewById(R.id.lb1);
Next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
edit.setText(text.getText());
}
});
}

Answer 1

What you want to do is have two separate activities, one to edit the text, and one to display it.
The first one you want to set the layout to layout_main, and set a callback for the button. Inside the callback you want:
final EditText text = (EditText)findViewById(R.id.broj1);
Intent intent = new Intent(MainAct.this, NumGen.class);
Bundle bundle = new Bundle();
bundle.putString("mString",text.getText().toString());
intent.putExtras(bundle);
startActivity(intent);
Then inside your second activity (NumGen?) you can get that string you saved by doing this:
Bundle data = getIntent().getExtras();
String mString="";
if(data.containsKey("mString")){ mString=data.getString("mString"); }
One of the main issues it looks like you might be having is the ids defined in your XML files aren't the same as the ids in your code. After that, read up on how Activities work and pass information.
