老師，我把客戶端的代碼放在android程序里，給一個button監聽事件，就是調用這個socket方法，但是一點button就閃退了，沒連接上~protected?void?onCreate(Bundle?savedInstanceState)?{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_client);

btn=(Button)?findViewById(R.id.button2);

btn.setOnClickListener(new?OnClickListener()?{

@Override

public?void?onClick(View?v)?{

initClientSocket();

}

});

}

@Override

public?boolean?onCreateOptionsMenu(Menu?menu)?{

//?Inflate?the?menu;?this?adds?items?to?the?action?bar?if?it?is?present.

getMenuInflater().inflate(R.menu.client,?menu);

return?true;

}

@Override

public?boolean?onOptionsItemSelected(MenuItem?item)?{

//?Handle?action?bar?item?clicks?here.?The?action?bar?will

//?automatically?handle?clicks?on?the?Home/Up?button,?so?long

//?as?you?specify?a?parent?activity?in?AndroidManifest.xml.

int?id?=?item.getItemId();

if?(id?==?R.id.action_settings)?{

return?true;

}

return?super.onOptionsItemSelected(item);

}

private?void?initClientSocket()?{

try?{

Socket?socket=new?Socket("192.168.191.1",8888);

OutputStream?os=socket.getOutputStream();

PrintWriter?pw=new?PrintWriter(os);

pw.write("nihao");

pw.flush();

socket.shutdownOutput();

pw.close();

os.close();

socket.close();

}?catch?(UnknownHostException?e)?{

//?TODO?Auto-generated?catch?block

e.printStackTrace();

}?catch?(IOException?e)?{

//?TODO?Auto-generated?catch?block

e.printStackTrace();

}

}

}
