微信登錄
注意:
1.在你的包名相應目錄下新建一個wxapi目錄桐磁，并在該wxapi目錄下新增一個WXEntryActivity類身弊，并實現(xiàn)IWXAPIEventHandler
2.包名歇终，appid要和微信開發(fā)者申請的一致
3.在build.gradle下配置
signingConfigs {
debug {
storeFile file('C:\\Users\\hp\\AndroidStudioProject\\demo.key.jks')
storePassword '111111'
keyPassword '111111'
keyAlias = 'key0'
}
}
包名修改完成后荒适，對應的 applicationId " "中的包名也要修改
1.配置文件
<activity
android:name="com.personal.revenant.baoyouqian.wxapi.WXEntryActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:exported="true"
android:launchMode="singleTop"
android:screenOrientation="portrai
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
2.全局配置
package com.personal.revenant.baoyouqian.app;
import android.app.Application;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import com.personal.revenant.baoyouqian.utlis.Constant;
import com.tencent.mm.opensdk.constants.ConstantsAPI;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
public class Myapp extends Application {
public static Myapp instance;
public static Context mContext;
public static IWXAPI iwxapi;
@Override
public void onCreate() {
super.onCreate();
this.mContext = this;
instance = this;
registToWX();
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// 將該app注冊到微信
iwxapi.registerApp(Constant.WEIXINAPPID);
}
}, new IntentFilter(ConstantsAPI.ACTION_REFRESH_WXAPP));
}
private void registToWX() {
//AppConst.WEIXIN.APP_ID是指你應用在微信開放平臺上的AppID，記得替換夯接。
iwxapi = WXAPIFactory.createWXAPI(this, Constant.WEIXINAPPID, false);
// 將該app注冊到微信
iwxapi.registerApp(Constant.WEIXINAPPID);
}
public static Context getContext() {
return mContext;
}
}
3.調用接口
if (!Myapp.iwxapi.isWXAppInstalled()) {
toast("您的設備未安裝微信客戶端");
} else {
SendAuth.Req req = new SendAuth.Req();
req.scope = "snsapi_userinfo";
// req.state = "wechat_sdk_demo";
Myapp.iwxapi.sendReq(req);
}
4.回調
public class WXEntryActivity extends Activity implements IWXAPIEventHandler {
// 獲取第一步的code后舌菜，請求以下鏈接獲取access_token
private String GetCodeRequest = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";
// 獲取用戶個人信息
private String GetUserInfo = "https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID";
private String access_token = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Myapp.iwxapi.handleIntent(getIntent(),this);
}
// 微信發(fā)送請求到第三方應用時，會回調到該方法
@Override
public void onReq(BaseReq baseReq) {
finish();
}
// 第三方應用發(fā)送到微信的請求處理后的響應結果澈蚌，會回調到該方法
@Override
public void onResp(BaseResp baseResp) {

微信分享
1.調用接口
public void WXshare(String title, String url, String description, Context context) {
WXWebpageObject textObj = new WXWebpageObject();
textObj.webpageUrl = url;
WXMediaMessage msg = new WXMediaMessage(textObj);
msg.title=title;
msg.description = description;
//縮略圖
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.img_2);
Bitmap thumbBmp = Bitmap.createScaledBitmap(bmp, 150, 150, true);
bmp.recycle();
msg.thumbData = Util.bmpToByteArray(thumbBmp, true);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction =buildTransaction("webpage");
req.message = msg;
req.scene = SendMessageToWX.Req.WXSceneSession;
//req.userOpenId =;
Myapp.iwxapi.sendReq(req);
}
public static String buildTransaction(final String type) {
return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
}
2.工具類
public class Util {
private static final String TAG = "SDK_Sample.Util";
public static byte[] bmpToByteArray(final Bitmap bmp, final boolean needRecycle) {
ByteArrayOutputStream output = new ByteArrayOutputStream();
bmp.compress(CompressFormat.PNG, 100, output);
if (needRecycle) {
bmp.recycle();
}
byte[] result = output.toByteArray();
try {
output.close();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}
