Android实现原生分享功能

本文实例为大家分享了Android实现分享功能的具体代码，供大家参考，具体内容如下

因为公司的需求，最近一直在做分享这一块的功能。大概有这样几种思路：

1.使用Intent调用andoird原生的分享功能；

2.使用第三方的sdk，比如ShareSdk或者友盟；

3.去对应的平台下载jar包，参考官方设计文档写出自己的分享demo，但这种一般也比较复杂，尤其搞不懂qq和微信一家公司的，为什么微信那么麻烦。

不废话了，直接上代码：

一. 新建ShareUtil.java类

import java.io.File; 
 
import android.content.ComponentName; 
import android.content.Context; 
import android.content.Intent; 
import android.content.pm.PackageManager; 
import android.content.pm.PackageManager.NameNotFoundException; 
import android.net.Uri; 
import android.text.TextUtils; 
import android.widget.Toast; 
public class ShareUtil { 
  private Context context; 
   
  public ShareUtil(Context context) { 
    this.context = context; 
  } 
   
  public static final String WEIXIN_PACKAGE_NAME = ""; 
  public static final String QQ_PACKAGE_NAME = ""; 
// public static final String ; 
   
   
   
  public void shareText(String packageName,String className,String content,String title,String subject){ 
      Intent intent =new Intent(); 
      intent.setAction(Intent.ACTION_SEND); 
      intent.setType("text/plain"); 
  //   if(null != className && null != packageName && !TextUtils.isEmpty(className) && !TextUtils.isEmpty(packageName)){ 
  //      
  //   }else {      
  //     if(null != packageName && !TextUtils.isEmpty(packageName)){ 
  //intent.setPackage(packageName); 
  //     } 
  //   } 
      if(stringCheck(className) && stringCheck(packageName)){ 
 ComponentName componentName = new ComponentName(packageName, className); 
 intent.setComponent(componentName); 
      }else if(stringCheck(packageName)){ 
 intent.setPackage(packageName); 
      } 

      intent.putExtra(Intent.EXTRA_TEXT, content); 
      if(null != title && !TextUtils.isEmpty(title)){      
 intent.putExtra(Intent.EXTRA_TITLE, title); 
      } 
      if(null != subject && !TextUtils.isEmpty(subject)){ 
 intent.putExtra(Intent.EXTRA_SUBJECT, subject); 
      } 
      intent.putExtra(Intent.EXTRA_TITLE, title); 
      Intent chooserIntent = Intent.createChooser(intent, "分享到："); 
      context.startActivity(chooserIntent); 
    } 
   
   
  public void shareUrl(String packageName,String className,String content,String title,String subject){ 
    Intent intent =new Intent(); 
    intent.setAction(Intent.ACTION_SEND); 
    intent.setType("text/plain"); 
//   if(null != className && null != packageName && !TextUtils.isEmpty(className) && !TextUtils.isEmpty(packageName)){ 
//      
//   }else {      
//     if(null != packageName && !TextUtils.isEmpty(packageName)){ 
//intent.setPackage(packageName); 
//     } 
//   } 
    if(stringCheck(className) && stringCheck(packageName)){ 
      ComponentName componentName = new ComponentName(packageName, className); 
      intent.setComponent(componentName); 
    }else if(stringCheck(packageName)){ 
      intent.setPackage(packageName); 
    } 
     
    intent.putExtra(Intent.EXTRA_TEXT, content); 
    if(null != title && !TextUtils.isEmpty(title)){      
      intent.putExtra(Intent.EXTRA_TITLE, title); 
    } 
    if(null != subject && !TextUtils.isEmpty(subject)){ 
      intent.putExtra(Intent.EXTRA_SUBJECT, subject); 
    } 
    intent.putExtra(Intent.EXTRA_TITLE, title); 
    Intent chooserIntent = Intent.createChooser(intent, "分享到："); 
    context.startActivity(chooserIntent); 
  } 
   
   
  public void shareImg(String packageName,String className,File file){ 
    if(file.exists()){ 
      Uri uri = Uri.fromFile(file); 
      Intent intent = new Intent(); 
      intent.setAction(Intent.ACTION_SEND); 
      intent.setType("image 
  public void shareAudio(String packageName,String className,File file){ 
    if(file.exists()){ 
      Uri uri = Uri.fromFile(file); 
      Intent intent = new Intent(); 
      intent.setAction(Intent.ACTION_SEND); 
      intent.setType("audio 
  public void shareVideo(String packageName,String className,File file){ 
    setIntent("video 
  public void shareImgToWXCircle(String title,String packageName,String className, File file){ 
    if(file.exists()){ 
      Uri uri = Uri.fromFile(file); 
      Intent intent = new Intent(); 
      ComponentName comp = new ComponentName(packageName, className); 
      intent.setComponent(comp); 
      intent.setAction(Intent.ACTION_SEND); 
      intent.setType("image 
  public boolean checkInstall(String packageName){ 
    try { 
      context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES); 
      return true; 
    } catch (NameNotFoundException e) { 
      e.printStackTrace(); 
      Toast.makeText(context, "请先安装应用app", 1500).show(); 
      return false; 
    } 
  } 
   
   
  public void toInstallWebView(String url){ 
    Intent intent = new Intent(); 
    intent.setAction(Intent.ACTION_VIEW); 
    intent.setData(Uri.parse(url)); 
    context.startActivity(intent); 
  } 
   
  public static boolean stringCheck(String str){ 
    if(null != str && !TextUtils.isEmpty(str)){ 
      return true; 
    }else { 
      return false; 
    } 
  } 
} 

二. MainActivity.java类

import java.io.File; 
import android.app.Activity; 
import android.os.Bundle; 
import android.os.Environment; 
import android.view.View; 
import android.view.View.OnClickListener;

public class MainActivity extends Activity implements onClickListener { 
  Button btnQQ; 
  Button btnWX; 
  Button btnMore; 
  Button btnWxFriendText; 
  Button btnQQFriendText; 
  Button btnWxFriendImg; 
  Button btnQQFriendImg; 
  Button btnWxFriendAudio; 
  Button btnQQFriendAduio; 
  Button btnWxFriendVideo; 
  Button btnQQFriendVideo; 
 
  ShareUtil shareUtil; 
  private Button btn_wxCircle_img; 
 
  @Override 
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    btnQQ = (Button) findViewById(R.id.btn_qq); 
    btnWX = (Button) findViewById(R.id.btn_wx); 
    btnMore = (Button) findViewById(R.id.btn_more); 
    btnWxFriendText = (Button) findViewById(R.id.btn_wxFriend); 
    btnQQFriendText = (Button) findViewById(R.id.btn_qqFriend); 
    btnWxFriendImg = (Button) findViewById(R.id.btn_wxFriend_img); 
    btnQQFriendImg = (Button) findViewById(R.id.btn_qqFriend_img); 
    btnWxFriendAudio = (Button) findViewById(R.id.btn_wxFriend_audio);

    btn_wxCircle_img = (Button) findViewById(R.id.btn_wxCircle_img); 
 
    btnQQ.setonClickListener(this); 
    btnWX.setonClickListener(this); 
    btnMore.setonClickListener(this); 
    btnWxFriendText.setonClickListener(this); 
    btnQQFriendText.setonClickListener(this);

    shareUtil = new ShareUtil(this); 
  } 
 
  @Override

    switch (v.getId()) { 
    // qq&文字 
    case R.id.btn_qq:

      } else { 
 shareUtil.toInstallWebView("http://weixin.qq.com/download"); 
      } 
      break; 
    // qq朋友&文字 
    case R.id.btn_qqFriend: 
      if (shareUtil.checkInstall("com.tencent.mobileqq")) {

   "com.tencent.mm.ui.tools.ShareToTimeLineUI", fileImage); 
      break; 
    } 
  } 
}

三.布局文件activity_main.xml

其中微信的分享只能分享文字和图片，不能单独分享图片或者文字。
