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：

1、LoginWindow.java －－登录窗口

package com.hemi.rhet;
import com.hemi.rhet.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
public class LoginWindow extends Activity {
 @Override
 public void onCreate(Bundle savedInstanceState) {
  System.out.println("enter LoginWindow.onCreate()!");
  super.onCreate(savedInstanceState);
  setContentView(R.layout.login_window);
  mUserName = (EditText)findViewById(R.id.username);
  mUserPasswd = (EditText)findViewById(R.id.userpasswd);
  cbx_cmwap = (CheckBox) findViewById(R.id.cbx_cmwap);
  loginButton = (Button) findViewById(R.id.login_button);
  exitButton = (Button) findViewById(R.id.exit_button);
  loginBtnListener = new View.OnClickListener() {
   public void onClick(View view) {
    LoginWindow.isCmwap = cbx_cmwap.isChecked();
    if (view == loginButton) {
      launchFetion();
    } else if(view == exitButton) {
     finish();
    }
   }
  };
  loginButton.setOnClickListener(loginBtnListener);
  exitButton.setOnClickListener(loginBtnListener);
 }
 private void launchFetion() {
  Intent i = new Intent(this, FuncSelector.class);
  i.putExtra(KEY_LOGIN_NAME, mUserName.getText().toString());
  i.putExtra(KEY_LOGIN_PASSWD, mUserPasswd.getText().toString());
  i.putExtra(KEY_LOGIN_TYPE, cbx_cmwap.isChecked());
  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;
 }
 private Button loginButton, exitButton;
 private EditText mUserName;
 private EditText mUserPasswd;
 private CheckBox cbx_cmwap;

 }
 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。
