handleIntent

boolean handleIntent(android.content.Intent data,
                     IWXAPIEventHandler handler)

Call handleIntent(Intent, IWXAPIEventHandler) in BroadcastReceiver. For example

 class SampleEventProcessor extends BroadcastReceiver implements IWXAPIEventHandler {
 
        // override broadcast receiver
        public void onReceive(Context context, Intent data) {
                final IWXAPI api = WXAPIFactory.createWXAPI(context, null);
                if (api.handleIntent(data, this)) {
                        // intent handled as wechat request/response
                        return;
                }
 
                // process other intent as you like
        }
 
        // process request
        public void onReq(BaseReq req) {
 
                switch (req.getType()) {
                case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:
                        Toast.makeText(context, "get message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:
                        Toast.makeText(context, "show message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 
        // process response
        public void onResp(BaseResp resp) {
                switch (resp.getType()) {
                case ConstantsAPI.COMMAND_SENDAUTH:
                        Toast.makeText(context, "get auth resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX:
                        // Process SendMessageToWX.Resp returned by WeChat
                        Toast.makeText(context, "send messsage to wx resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 }
 
 

and DON'T FORGET to add SampleEventProcessor BroadcastReceiver in AndroidManifest.xml

在BroadcastReceiver中调用handleIntent(Intent, IWXAPIEventHandler)，例如：

 class SampleEventProcessor extends BroadcastReceiver implements IWXAPIEventHandler {
 
        // override broadcast receiver
        public void onReceive(Context context, Intent data) {
                final IWXAPI api = WXAPIFactory.createWXAPI(context, null);
                if (api.handleIntent(data, this)) {
                        // intent handled as wechat request/response
                        return;
                }
 
                // process other intent as you like
        }
 
        // process request
        public void onReq(BaseReq req) {
 
                switch (req.getType()) {
                case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:
                        Toast.makeText(context, "get message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:
                        Toast.makeText(context, "show message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 
        // process response
        public void onResp(BaseResp resp) {
                switch (resp.getType()) {
                case ConstantsAPI.COMMAND_SENDAUTH:
                        Toast.makeText(context, "get auth resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX:
                        // 处理微信主程序返回的SendMessageToWX.Resp
                        break;
 
                default:
                        break;
                }
        }
 }

send request to wechat app

参数:

req -

返回:

true if sent
