Question

嗨我在Android键盘按.（点）时试图收到此事件

 public boolean onKey(View v, int keyCode, KeyEvent event) {

   if (keyCode == '.') {
        Log.d("dot pressed" "dot presed");

我哪里出错了？

Answer 1

请试试这个

 public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode == KeyEvent.KEYCODE_NUMPAD_DOT) {
        Log.d("dot pressed" "dot presed");

    }
    return super.onKeyDown(keyCode, event);
}

您应该使用KeyEvent.KEYCODE_PERIOD
