2、弹框代码

public class ShareUtils {

3、WxShareUtils
封装了2个调用微信分享的方法
package com.example.xy.utils;
import android.content.Context;
import android.graphics.Bitmap;
import com.blankj.utilcode.util.ToastUtils;
import com.tencent.mm.opensdk.modelmsg.SendMessageToWX;
import com.tencent.mm.opensdk.modelmsg.WXMediaMessage;
import com.tencent.mm.opensdk.modelmsg.WXMiniProgramObject;
import com.tencent.mm.opensdk.modelmsg.WXWebpageObject;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
public class WxShareUtils {
/**
* 分享网页类型至微信
*
* @param context 上下文
* @param appId 微信的appId
* @param webUrl 网页的url
* @param title 网页标题
* @param content 网页描述
* @param bitmap 位图
* @param tag 标识 1 好友对话框 2 朋友圈
*/
public static void shareWeb(Context context, String appId, String webUrl, String title, String content, Bitmap bitmap,int tag) {
// 通过appId得到IWXAPI这个对象
IWXAPI wxapi = WXAPIFactory.createWXAPI(context, appId);
// 检查手机或者模拟器是否安装了微信
if (!wxapi.isWXAppInstalled()) {
ToastUtils.showShort("您还没有安装微信");
return;
}
// 初始化一个WXWebpageObject对象
WXWebpageObject webpageObject = new WXWebpageObject();
// 填写网页的url
webpageObject.webpageUrl = webUrl;
// 用WXWebpageObject对象初始化一个WXMediaMessage对象
WXMediaMessage msg = new WXMediaMessage(webpageObject);
// 填写网页标题、描述、位图
msg.title = title;
msg.description = content;
// 如果没有位图，可以传null，会显示默认的图片
msg.setThumbImage(bitmap);
// 构造一个Req
SendMessageToWX.Req req = new SendMessageToWX.Req();
// transaction用于唯一标识一个请求（可自定义）
req.transaction = "webpage";
// 上文的WXMediaMessage对象
req.message = msg;
// SendMessageToWX.Req.WXSceneSession是分享到好友会话
// SendMessageToWX.Req.WXSceneTimeline是分享到朋友圈
if(tag ==1){
req.scene = SendMessageToWX.Req.WXSceneSession;
}else {
req.scene = SendMessageToWX.Req.WXSceneTimeline;
}
// 向微信发送请求
wxapi.sendReq(req);
}
/**
* 分享微信小程序
* @param context
* @param appId
* @param webUrl
* @param title
* @param content
* @param bitmap 图片资源
*/
public static void shareMiniPro(Context context, String appId, String webUrl, String title, String content, Bitmap bitmap){

// 检查手机或者模拟器是否安装了微信
if (!wxapi.isWXAppInstalled()) {
ToastUtils.showShort("您还没有安装微信");
return;
}
WXMiniProgramObject miniProgram = new WXMiniProgramObject();
miniProgram.webpageUrl=webUrl;//自定义
miniProgram.userName="xxxxxxx";//小程序端提供参数
miniProgram.path=webUrl;//小程序端提供参数
WXMediaMessage mediaMessage = new WXMediaMessage(miniProgram);
mediaMessage.title = title;//自定义
mediaMessage.description = content;//自定义
// Bitmap bitmap = BitmapFactory.decodeResource(SendToWXActivity.this.getResources(),R.drawable.fightk);
// Bitmap sendBitmap = Bitmap.createScaledBitmap(bitmap,180,180,true);
// bitmap.recycle();
mediaMessage.thumbData = Utils.bmpToByteArray(bitmap);
// mediaMessage.setThumbImage(bitmap);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = "";
req.scene = SendMessageToWX.Req.WXSceneSession;
req.message = mediaMessage;
wxapi.sendReq(req);
}
}
工具类Util
public class Utils {
/**
*bmp转字节数组
* */
public static byte[] bmpToByteArray(Bitmap bitmap){
int bytes = bitmap.getByteCount();
ByteBuffer buf = ByteBuffer.allocate(bytes);
bitmap.copyPixelsToBuffer(buf);
byte[] byteArray = buf.array();
return byteArray;
}
}
补充：
如果只是类似淘宝考虑的复制粘贴，不需要使用分享API，只调起微信即可。
