Force Close when i run this application
I am new to programming. I'm creating a simple app which will handle my Button click event. I have added the button using xml and linked it to the program, but the app force closes immediately after I run it.
Here is the code:
public class Sparkling extends Activity implements OnClickListener
{
Button b;
public void onCreate(Bundle savedInstanceState)
{开发者_运维知识库
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
b=(Button)findViewById(R.id.Button1);
b.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
//actions....
}
}
Without having any stack trace info, my guess would be Button1 is missing from or is misspelled on main.xml or something is wrong with your manifest file.
I found out what had happened.
I was using:
android:name="@+id/Button1"
instead of:
android:id="@+id/Button1"
