How to add a button in android?

Question

Can anybody tell how to add a button in android?

Answer 1

Check this Android Button tutorial; this simple example creates a Close Button.

All you need to do is:

1.Add Button widget to your Layout

<Button android:id="@+id/close"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_alignParentBottom="true"     android:text="@string/title_close" /> 

2.Attach a setOnClickListener method to the button instance:

protected void onCreate(Bundle savedInstanceState) {   this.setContentView(R.layout.layoutxml);   this.closeButton = (Button)this.findViewById(R.id.close);   this.closeButton.setOnClickListener(new OnClickListener() {     @Override     public void onClick(View v) {       finish();     }   }); }
