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 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 boolean isCmwap = false;}

2. FuncSelector.java －－ 功能模块选择窗口
