1、build.gradle下添加微信sdk依賴

compile ('com.xyzlf.share:sharesdk:0.0.10') {exclude group: 'com.android.support', module: 'appcompat-v7' }

2、MainActivity文件夾下創建wxapi文件夾WXEntryActivity類，并配置到manifest里面：

public class WXEntryActivity extends Activity implements IWXAPIEventHandler {private IWXAPI api;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);api = WXAPIFactory.createWXAPI(this, ManifestUtil.getWeixinKey(this), false);api.handleIntent(getIntent(), this);}@Overrideprotected void onNewIntent(Intent intent) {super.onNewIntent(intent);setIntent(intent);api.handleIntent(intent, this);}@Overridepublic void onReq(BaseReq req) {}@Overridepublic void onResp(BaseResp resp) {Intent intent = new Intent();intent.setAction(ShareConstant.ACTION_WEIXIN_CALLBACK);intent.putExtra(ShareConstant.EXTRA_WEIXIN_RESULT, resp.errCode);sendBroadcast(intent);finish();} } <!-- 微信分享注冊 --> <activityandroid:name=".wxapi.WXEntryActivity"android:configChanges="keyboardHidden|orientation|screenSize"android:exported="true"android:screenOrientation="portrait"android:theme="@android:style/Theme.Translucent.NoTitleBar" />

3、分享工具類，這里注冊 微信開放平臺 的AppID，即可分享

4、起調微信分享

String strTinyCreate = "分享一個微創業\n" ; ShareUtil.getInstance(AddwcrrActivity.this, 0).setDetail(strTinyCreate).setShareType(ShareUtil.SHARE_WX_FRIEND).share(more_loadDialog);

5、說明：

More_LoadDialog是個緩沖動畫。可要可不要。可用你的緩沖動畫
