微信開放平臺創(chuàng)建應(yīng)用，操作步驟請看博客：Android之微信開放平臺創(chuàng)建應(yīng)用
成功之后得到AppId糯钙，放入項(xiàng)目中粪狼。
public class Constants {
// APP_ID 替換為你的應(yīng)用從官方網(wǎng)站申請到的合法appId==
public static final String APP_ID = "wx1b73fd7b49ffa027";

文本分享代碼：
// 初始化一個(gè)WXTextObject對象
WXTextObject textObj = new WXTextObject();
textObj.text = text;
// 用WXTextObject對象初始化一個(gè)WXMediaMessage對象
WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = textObj;
// 發(fā)送文本類型的消息時(shí)，title字段不起作用
msg.title = "Will be ignored";
msg.description = text;
// 構(gòu)造一個(gè)Req
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("text"); // transaction字段用于唯一標(biāo)識一個(gè)請求
req.message = msg;
/**
* 判斷是否是朋友圈
*/
req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;
// 調(diào)用api接口發(fā)送數(shù)據(jù)到微信
api.sendReq(req);
