Question

Can the Android emulator capture a key-press event of the computer (running the emulator) keyboard, such as: direction key, backspace key and enter key? If it could do that, can you tell me the key code of the implentation? Thanks a lot.

Answer 1

The mapping between PC keyboard keys and devices keys is detailed here: http://developer.android.com/tools/help/emulator.html#KeyMapping

And you can respond to them using the keycodes that are listed here: http://developer.android.com/reference/android/view/KeyEvent.html

For instance:

public class TestActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    Log.i("test", "onKeyDown(" + keyCode + ", " + event +")");
    return super.onKeyDown(keyCode, event);
}

}
