Android SendKey方法

Question

有没有办法将密钥或字符发送到另一个程序活动？像C# SendKey method

这样的东西

Answer 1

您可以使用此方法：

private String key;



   @Override
    public boolean dispatchKeyEvent(KeyEvent event) {
     Log.i("Key pressed was : ", String.valueOf(event.getKeyCode()));
     key = String.valueof(event.getKeyCode());
     return super.dispatchKeyEvent(event);
}

然后使用Intent您可以将值发送到另一个活动

Intent intent = new Intent(this,MyActivity.class);
intent.putExtra("keyString, key);

并在您的其他活动中检索它：

Intent intent = getIntent();
String key = intent.getStringExtra("keyString");
