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;

 }
 @Override
 public boolean onKeyDown(int keyCode, KeyEvent msg) {
//  System.out.println("enter onKeyDown() in LoginWindow!");
//
//  if (null != loginBtnListener) {
//   View aview = getCurrentFocus();
//   loginBtnListener.onClick(aview);

 }
 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。

Android4.4 WebAPI实现拍照上传功能

网上有很多关于拍照上传的实现方法,如果用新版本android去运行有可能会发现根本实现不了.主要原因是android从4.4版本开始通过intent.ACTION_GET_CONTENT打开选择器后,getData()返回的URI没有包含真实的文件路径,而是像这样"content://com.android.providers.media.documents/document/image:1234",以至于用传统的方式找不到图片的路径.最简单的解决办法是用intent.ACTION_P

Android使用Retrofit仿微信多张图片拍照上传

Android 仿照微信发说说,既能实现拍照,选图库,多图案上传,使用Retrofit技术. 使用方法:详见http://www.jb51.net/article/103009.htm 项目的运行效果: 服务器端接收文件的action UploadFile.java @Controller public class UploadFile extends ActionSupport { /** * */ private static final long serialVersionUID = 1L

Android 高仿微信朋友圈拍照上传功能

模仿微信朋友圈发布动态,输入文字支持文字多少高度自增,有一个最小输入框高度,输入文字有限制,不过这些都很easy! 1. PhotoPicker的使用 这是一个支持选择多张图片,点击图片放大,图片之间左右滑动互相切换的库,同时支持图片删除的库,效果类似微信. (1) 添加PhotoPicker的架包 (2) 使用 选择图片:安卓6.0以后需要在代码中添加读写sd卡和相机的权限 当然清单文件中也需要添加的 PhotoPicker.builder() .setPhotoCount(maxPhoto)

Android 高仿微信朋友圈动态支持双击手势放大并滑动查看图片效果

最近参与了开发一款旅行APP,其中包含实时聊天和动态评论功能,终于耗时几个月几个伙伴完成了,今天就小结一下至于实时聊天功能如果用户不多的情况可以scoket实现,如果用户万级就可以采用开源的smack + opnefile实现,也可以用mina开源+XMMP,至于怎么搭建和实现,估计目前github上一搜一大把,至于即时通讯怕误人子弟,暂且不做介绍,现就把实现的一个微信朋友圈的小功能介绍一下. 先上效果图: 一拿到主流的UI需求,大致分析下,需要我ListView嵌套Gridview,而grid

Android仿微信朋友圈全文、收起功能的实例代码

前言 一般在社交APP中都有类似朋友圈的功能,其中发表的动态内容很长的时候不可能让它全部显示.这里就需要做一个仿微信朋友圈全文.收起功能来解决该问题.在网上看到一个例子-->http://www.jb51.net/article/105251.htm,写的很不错,但是有个bug,他这个Demo只有在条目固定的时候才正常,当增加.删除条目的时候会出现全文.收起显示混乱的问题.原因是他使用了固定的position作为key来保存当前显示的状态.这篇文章在他的基础上进行优化. 效果图 具体代码 (详细

Android自定义TextView仿微信朋友圈文字展开全文功能

Android自定义TextView仿微信朋友圈文字信息,展开全文功能 代码及注释如下: 首先写一个xml文件 showmore.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical

Android自定义SwipeRefreshLayout高仿微信朋友圈下拉刷新

上一篇文章里把SwipeRefreshLayout的原理简单过了一下,大致了解了其工作原理,不熟悉的可以去看一下:http://www.jb51.net/article/89310.htm 上一篇里最后提到,SwipeRefreshLayout的可定制性是比较差的,看源码会发现跟样式相关的几个类都是private的而且方法是写死的,只暴露出了几个颜色设置的方法.这样使得SwipeRefreshLayout的使用比较简单,主要就是设置一个监听器在onRefresh方法里完成刷新逻辑.讲道理Swip

Android GridView仿微信朋友圈显示图片

最近项目要求上传多图并且多图显示,而且要规则的显示,就像微信朋友圈的图片显示一样. 利用GridView再适合不过了,GridView可以动态加载图片的数量,而且还比较规律,下面说一下自己的思路: 1.获取网络图片 2.初始化gridview,自定义适配器 3.根据图片数量设置gridview的列数 4.更新适配器 下面贴上部分源码并给大家解析一下 一.首先是GridView的item <com.view.SquareLayout xmlns:android="http://schemas

Android仿微信朋友圈点赞和评论功能

最近在做朋友圈的项目,所以写一个Android仿朋友圈点赞和评论功能Demo,代码就是简单实现了一下功能,没有做优化,凑合看 图文排列是用的RecyclerView实现的,弹窗效果是用的自定义的PopupWindow,点赞应该是在本地请求数据库,设置一个flag,获取当前用户的id后,带着id向服务器post一个flag,评论就比较简单了,也是获取当前朋友id(或者昵称),带着内容,向服务器post 贴代码: package com.example.lenovo.dianzandemo; imp

Android 仿微信朋友圈点赞和评论弹出框功能

贡献/下载源码:https://github.com/mmlovesyy/PopupWindowDemo 本文简单模仿微信朋友圈的点赞和评论弹出框,布局等细节请忽略,着重实现弹出框.发评论,及弹出位置的控制. 1. 微信弹出框 微信朋友圈的点赞和评论功能,有2个组成部分: 点击左下角的"更多"按钮,弹出对话框: 点击评论,弹出输入框,添加评论并在页面中实时显示: 微信朋友圈点赞和评论功能 2. 实际效果 本文将建一个 ListView,在其 Item 中简单模仿微信的布局,然后着重实现

Android高仿微信表情输入与键盘输入详解

最近公司在项目上要使用到表情与键盘的切换输入,自己实现了一个,还是存在些缺陷,比如说键盘与表情切换时出现跳闪问题,这个相当困扰我,不过所幸在Github(其中一个不错的开源项目,其代码整体结构很不错)并且在论坛上找些解决方案,再加上我也是研究了好多个开源项目的代码,最后才苦逼地整合出比较不错的实现效果,可以说跟微信基本一样(嘿嘿,只能说目前还没发现大Bug,若发现大家一起日后慢慢完善,这里我也只是给出了实现方案,拓展其他表情我并没有实现哈,不过代码中我实现了一个可拓展的fragment模板以便大
