android - 如何在 android 中使用虚拟键盘（在按下后显示 Toast 的键上捕获事件）

Question

我正在对虚拟键盘进行研发（如何捕捉关键事件），但没有发现更多成功我对虚拟键盘的了解很少

我们需要实现

onKeyboradActionListener

/* and these override methode*/

public void onKey(int primaryCode, int[] keyCodes) {
    // TODO Auto-generated method stub

}

@Override
public void onPress(int primaryCode) {
    // TODO Auto-generated method stub

}

@Override
public void onRelease(int primaryCode) {
    // TODO Auto-generated method stub

}
