微信分享申请过程比较麻烦，在这里就不去介绍了。可以上官网去查看教程。
- 清单文件配置
<!--微信分享回调 -->
<activity
android:name=".wxapi.WXEntryActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:configChanges="keyboardHidden|orientation|screenSize"
android:exported="true"
android:screenOrientation="portrait" />
- 初始化
private IWXAPI mAPI;
//注册微信
mAPI = WXAPIFactory.createWXAPI(this, BaseConstants.WX_APP_KEY);
mAPI.registerApp(BaseConstants.WX_APP_KEY);
- 分享方法，包括分享到好友和朋友圈
public void shareToWX(IWXAPI mAPI, String text, Bitmap bitmap, boolean friend) {
Log.i(TAG, "share to wx");
WXImageObject mWXImage = new WXImageObject(bitmap);
WXMediaMessage mWXMsg = new WXMediaMessage();
mWXMsg.mediaObject = mWXImage; //图片
mWXMsg.title = text; //文本描述
/*Bitmap thumb = Bitmap.createScaledBitmap(bitmap, 200, 200, true);
mWXMsg.thumbData = ImageUtil.bmpToByteArray(thumb, true); //设置缩略图*/
//构造一个Req
SendMessageToWX.Req mReq = new SendMessageToWX.Req();
if (friend) {
mReq.scene = SendMessageToWX.Req.WXSceneSession; //分享至好友
} else {
int sdkApi = mAPI.getWXAppSupportAPI();
if (sdkApi >= 0x21020001) {
mReq.scene = SendMessageToWX.Req.WXSceneTimeline; //分享至朋友圈
} else {
Toast.makeText(mContext, mContext.getString(R.string.WX_DO_NOT_SUPPORT_SHARE_TO_MOMEN),
Toast.LENGTH_SHORT).show();
return;
}
}
mReq.transaction = String.valueOf(System.currentTimeMillis());
mReq.message = mWXMsg;
mAPI.sendReq(mReq); //分享调用
}
- 重写回调类
public class WXEntryActivity extends Activity implements IWXAPIEventHandler {
private final String TAG = WXEntryActivity.class.getSimpleName();
private IWXAPI mWXAPI;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWXAPI = WXAPIFactory.createWXAPI(this, BaseConstants.WX_APP_KEY, false);
mWXAPI.handleIntent(getIntent(), this);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
mWXAPI.handleIntent(intent, this);
}
@Override
public void onReq(BaseReq baseReq) {
}
//第三方应用发送请求到微信的请求处理后的响应结果
@Override
public void onResp(BaseResp baseResp) {
switch ( baseResp.errCode ){
case BaseResp.ErrCode.ERR_OK:
Toast.makeText(this, getString(R.string.WEIBO_SHARE_SUCCESS), Toast.LENGTH_SHORT).show();
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
Toast.makeText(this, getString(R.string.WEIBO_SHARE_CANCELED), Toast.LENGTH_SHORT).show();
break;
case BaseResp.ErrCode.ERR_SENT_FAILED:
Toast.makeText(this, getString(R.string.WEIBO_SHARE_FAILED), Toast.LENGTH_SHORT).show();
break;
case BaseResp.ErrCode.ERR_AUTH_DENIED:
Log.i(TAG, "授权失败");
break;
case BaseResp.ErrCode.ERR_UNSUPPORT:
break;
}
finish();
}
}
