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();
    }
  });
}
