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

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可以将该值发送到另一个活动

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

而在你的其他活动检索：

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