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

packagecom.hemi.rhet;
importcom.hemi.rhet.R;
importandroid.app.Activity;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.view.KeyEvent;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
importandroid.widget.CheckBox;
importandroid.widget.EditText;
publicclassLoginWindowextendsActivity{
@Override
publicvoidonCreate(BundlesavedInstanceState){
System.out.println("enterLoginWindow.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=newView.OnClickListener(){
publicvoidonClick(Viewview){
LoginWindow.isCmwap=cbx_cmwap.isChecked();
if(view==loginButton){
launchFetion();
}elseif(view==exitButton){
finish();
}
}
};
loginButton.setOnClickListener(loginBtnListener);
exitButton.setOnClickListener(loginBtnListener);
}
privatevoidlaunchFetion(){
Intenti=newIntent(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
publicbooleanonKeyDown(intkeyCode,KeyEventmsg){
//System.out.println("enteronKeyDown()inLoginWindow!");
//
//if(null!=loginBtnListener){
//Viewaview=getCurrentFocus();
//loginBtnListener.onClick(aview);
//}
returnfalse;
}
privateButtonloginButton,exitButton;
privateEditTextmUserName;
privateEditTextmUserPasswd;
privateCheckBoxcbx_cmwap;
privateOnClickListenerloginBtnListener;
publicstaticfinalStringKEY_LOGIN_NAME="login_name";

}
};
okButton.setOnClickListener(loginBtnListener);
backButton.setOnClickListener(loginBtnListener);
}
privatevoidlaunchFetion(){

i.putExtra(KEY_LOGIN_NAME,mServerIP.getText().toString());
i.putExtra(KEY_LOGIN_PASSWD,mServerPort.getText().toString());
startActivity(i);
}
@Override

returnfalse;
}
publicstaticStringgetServerIp(){
returnserverIp;
}
publicstaticStringgetServerPort(){
returnserverPort;
}
privateButtonokButton,backButton;
privateEditTextmServerIP;
privateEditTextmServerPort;
privateOnClickListenerloginBtnListener;
publicstaticfinalStringKEY_LOGIN_NAME="login_name";

publicstaticfinalStringKEY_LOGIN_TYPE="login_type";
publicstaticStringserverIp="192.168.0.98";//;
publicstaticStringserverPort="8081";
}

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