android - Button Stays on Screen between Activities -

-

in android application i'm writing have button when pressed transitions new activity using intents. new activity has linearlayout, framelayout inside of it. when reach new activity button previous activity still on screen , still can tapped; however, causes application crash because onclick method isn't defined in new activity.

any idea why button remains? ideally i'd remove button.

edit, adding code:

intent intent = new intent(mainactivity.this, cameraactivity.class);             startactivity(intent);             finish();

could please show code? easier see, anywho try using this:

public void onclick(view v) { switch(v.getid()){      case r.id.bsubmit:                 if (a > 0 && b > 0 && c > 0 && d > 0){                 bundle basket = new bundle();                 basket.put***("key"); //depening on trying transfer 1 class other, different.                 intent = new intent(main.this, other.class);                 i.putextras(basket);                 startactivity(i);                 finish(); break;

that should on activity trying send from. btw using intent works, bundle(s) preferd far know.

also retrive go on other.java , write this: (inside oncreate)

bundle basket = getintent().getextras();         = basket.get***("key")

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
