I have a button in my activity, when you click the button an if statement is ran against its text label;

if(BTN_1.getText()=="firsttext"){
    //do some stuff, then...
    BTN_1.setText("secondtext");
}else if(BTN_1.getText()=="secondtext"){
    //do other stuff, then...
    BTN_1.setText("firsttext");
}

Firstly, if I hit the home button and go back to the desktop and then click back onto my app the view has reset its self; if I press the button and leave it in a state where the text of the button is "secondtext", when I return to my app it says "firsttext", how can I stop the view of my app refreshing its self like this?

Secondly, under my XML layout I have defined the buttons text; android:text="firsttext" But this won't actually match my if statement above, under onCreate of this app I have: BTN_CONNECT.setText("Connect"); But visually the text of the button is exactly the same, why won't it match?

Thanks for reading :)
