Android why this button is not available
I dont know why the last two buttons are not clickable, I have used the background (which I have set for them) many times and it works with other layouts, I am sure something like foucable or clickable is wrong, but I dont know , where exactly.

I'm 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);
when you press
@Override
public void onClick(View v) {
case R.id.b_orderMeal_cancel:
Toast.makeText(this, "roma", Toast.LENGTH_LONG);
break;
}
note
toast is not displayed

I think your design XML
is fine, so the 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 an interface OnClickListener
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;
}
}

Replace the method onClick()
below and tell us about logcat.
You seem to be trying to show toast
, but can't use the method .show()
to display the toast.
Try under code and let us know
@Override
public void onClick(View v) {
if(v.equals(b_send)){
Toast.makeText(this,"b_send clicked", Toast.LENGTH_LONG).show();
Log.d("TEMP TAG","b_send clicked");
} else if(v.equals(b_cancel)){
Toast.makeText(this,"b_cancel clicked", Toast.LENGTH_LONG).show();
Log.d("TEMP TAG","b_cancel clicked");
}
}

set clickable = true in xml for your button and try that in your code.
findViewById(R.id.b_orderMeal_send).setOnClickListener(commonClickListener);
findViewById(R.id.b_orderMeal_cancel).setOnClickListener(commonClickListener);
private OnClickListener commonClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
int selectedItemId = v.getId();
switch (selectedItemId) {
case R.id.b_orderMeal_send:
Toast.makeText(this, "roma", Toast.LENGTH_LONG).show();
break;
case R.id.b_orderMeal_cancel:
Toast.makeText(this, "roma", Toast.LENGTH_LONG).show();
break;
}
}
