Android拍照上传功能示例代码

本文实例讲述了Android实现拍照上传功能的方法。分享给大家供大家参考，具体如下：

}
@Override

}

 super.onCreate(savedInstanceState);
 setContentView(R.layout.config_window);
 mServerIP = (EditText)findViewById(R.id.serverip);

     Log.i("info", "IP is: "+serverIp+"/tPort is: "+serverPort);
     finish();
   } else if(view == backButton) {
     finish();
   }
  }
 };
 okButton.setOnClickListener(loginBtnListener);
 backButton.setOnClickListener(loginBtnListener);
}
private void launchFetion() {
 Intent i = new Intent(this, FuncSelector.class);
 i.putExtra(KEY_LOGIN_NAME, mServerIP.getText().toString());
 i.putExtra(KEY_LOGIN_PASSWD, mServerPort.getText().toString());
 startActivity(i);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent msg) {
//  System.out.println("enter onKeyDown() in LoginWindow!");
//
//  if (null != loginBtnListener) {
//   View aview = getCurrentFocus();
//   loginBtnListener.onClick(aview);
//  }
 return false;
}
public static String getServerIp() {
   return serverIp;
 }
 public static String getServerPort() {
   return serverPort;
 }
private Button okButton, backButton;
private EditText mServerIP;
private EditText mServerPort;
private OnClickListener loginBtnListener;
public static final String KEY_LOGIN_NAME = "login_name";
public static final String KEY_LOGIN_PASSWD = "login_passwd";
public static final String KEY_LOGIN_TYPE = "login_type";
public static String serverIp = "192.168.0.98"; //;
public static String serverPort = "8081";
}

还需要增加bg_logo.jpg、icon.png、photo_upload.png等几个图片。
