</ScrollView>

I am talking about the last two buttons

java

b_send = (Button) findViewById(R.id.b_orderMeal_send);
        b_send.setOnClickListener(this);
        b_cancel = (Button) findViewById(R.id.b_orderMeal_cancel);
        b_cancel.setOnClickListener(this);

on click

@Override
    public void onClick(View v) {
      case R.id.b_orderMeal_cancel:
        Toast.makeText(this, "roma", Toast.LENGTH_LONG);
        break;          
    }

note

the toast doesn’t appear

I don’t know why the last two buttons is not clickable, I used the
background (that i set to them ) many time and it works with another
layouts, I am sure that the wrong is something like foucable or
clickable but i don’t know where exactly .

I think your XML design is OK in all ways so problem is most likely in Java. Most likely you forgot to register OnClickListener for your Button(s).

Button btn = (Button) findViewById(R.id.b_orderMeal_send);
btn.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
       Toast.makeText(this, "Click event works.", Toast.LENGTH_SHORT).show();
     }
 }));

Or you can use OnClickListener interface and then

public void onClick(View v) {
   switch (v.getId()) {
      case R.id.b_orderMeal_send:
         Toast.makeText(this, "Click event works.", Toast.LENGTH_SHORT).show();
      break;
   }
}
