一 . 获取开发者APP_ID
打开微信开发者平台 创建应用 获取APP_ID，一般两三天审核通过
https://open.weixin.qq.com
二. 集成微信SDK
- 添加依赖
compile 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'
- AndroidManifest.xml 设置
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
3.调用的页面 例如MainActivity中
public class MainActivity extends AppCompatActivity {
private IWXAPI api;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
api = WXAPIFactory.createWXAPI(this, WXEntryActivity.APP_ID, true);
}
//分享文本
public void WeChatShare1(View view) {
String text = "测试数据";
WXTextObject textObj = new WXTextObject();
textObj.text = text;
initSend(textObj);
}
//分享图片
public void WeChatShare2(View view) {
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
WXImageObject object = new WXImageObject(bitmap);
initSend(object);
}
//分享链接
public void WeChatShare(View view) {
WXWebpageObject webpage = new WXWebpageObject();
webpage.webpageUrl = "http://www.baidu.com";
initSend(webpage);
}
private void initSend(WXMediaMessage.IMediaObject webpage) {
WXMediaMessage msg = new WXMediaMessage();
msg.title = "测试标题";
msg.description = "测试说明...";
msg.mediaObject = webpage;
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("webpage");
req.message = msg;
req.scene = SendMessageToWX.Req.WXSceneSession; //设置发送到朋友
// req.scene = SendMessageToWX.Req.WXSceneTimeline; //设置发送到朋友圈
api.sendReq(req);
}
private String buildTransaction(final String type) {
return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
}
}
三. 设置分享
-
包名相应目录下新建包名 wxapi，在里面新建类 WXEntryActivity 继承自AppCompatActivity即可(名字必须是这两个)
Paste_Image.png
public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
//申请的appid
public static final String APP_ID = "申请的ID";
//第三方app和微信通信的接口
private IWXAPI api;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
regToWx();
}
public void regToWx() {
//获取IWXAPI的实例
api = WXAPIFactory.createWXAPI(this, APP_ID, true);
//将应用appid注册到微信
api.registerApp(APP_ID);
//回调监听
api.handleIntent(getIntent(), this);
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp resp) {
String result;
switch (resp.errCode) {
case BaseResp.ErrCode.ERR_OK:
result = "分享成功";
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
result = "取消分享";
break;
case BaseResp.ErrCode.ERR_AUTH_DENIED:
result = "分享被拒绝";
break;
default:
result = "发送失败";
break;
}
Toast.makeText(this, result, Toast.LENGTH_SHORT).show();
finish();
}
}
- AndroidManifest.xml 添加，用于接受分享后的回掉，否则上一步中onReq()，onResp()无效
<!--微信回调-->
<application>
...
<activity
android:name=".wxapi.WXEntryActivity"
android:exported="true" />
</application>
