友盟整合第三方登入 + 登入註冊 + 跑馬燈 + Zxing二維碼
阿新 • • 發佈：2018-12-14
如圖:
第一步：建立工程
整合友盟第三方，建立工程時，包名：com.umeng.soexample
第二步：添加回調Activity
主要是qq和微信的回撥
第三步：匯入jar和res
將main資料夾以及platform（選擇你想使用的平臺即可）檔案下，對應的資原始檔和jar放入你的工程!
配置Android Manifest XML
<!-- 許可權 --> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /> <permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

Android6.0許可權適配
請檢視你的build.gradle檔案，如果 targetSdkVersion小於或等於22，可以忽略這一步，如果大於或等於23，需要做許可權的動態申請：
if(Build.VERSION.SDK_INT>=23){
String[] mPermissionList = new String[{
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.CALL_PHONE,
Manifest.permission.READ_LOGS,
Manifest.permission.READ_PHONE_STATE,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.SET_DEBUG_APP,
Manifest.permission.SYSTEM_ALERT_WINDOW,
Manifest.permission.GET_ACCOUNTS,
Manifest.permission.WRITE_APN_SETTINGS};
ActivityCompat.requestPermissions(this,mPermissionList,123);
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
}
初始化設定
自己建立一個類，整合AppLication
@Override
public void onCreate() {
super.onCreate();
UMConfigure.init(this,"5a12384aa40fa3551f0001d1"
,"umeng",UMConfigure.DEVICE_TYPE_PHONE,"");//58edcfeb310c93091c000be2 5965ee00734be40b580001a0
}
在onCreate方法中設定所需要的各個平臺的appkey值
PlatformConfig.setWeixin("wxdc1e388c3822c80b", "3baf1193c85774b3fd9d18447d76cab0");
//豆瓣RENREN平臺目前只能在伺服器端配置
PlatformConfig.setSinaWeibo("3921700954", "04b48b094faeb16683c32669824ebdad","http://sns.whalecloud.com");
PlatformConfig.setYixin("yxc0614e80c9304c11b0391514d09f13bf");
PlatformConfig.setQQZone("100424468", "c7394704798a158208a74ab60104f0ba");
PlatformConfig.setTwitter("3aIN7fuF685MuZ7jtXkQxalyi", "MK6FEYG63eWcpDFgRYw4w9puJhzDl0tyuqWjZ3M7XJuuG7mMbO");
PlatformConfig.setAlipay("2015111700822536");
PlatformConfig.setLaiwang("laiwangd497e70d4", "d497e70d4c3e4efeab1381476bac4c5e");
PlatformConfig.setPinterest("1439206");
PlatformConfig.setKakao("e4f60e065048eb031e235c806b31c70f");
PlatformConfig.setDing("dingoalmlnohc0wggfedpk");
PlatformConfig.setVKontakte("5764965","5My6SNliAaLxEm3Lyd9J");
PlatformConfig.setDropbox("oz8v5apet3arcdy","h7p2pjbzkkxt02a");
PlatformConfig.setYnote("9c82bf470cba7bd2f1819b0ee26f86c6ce670e9b");
開始第三方登入
在Activity中寫程式碼；
獲取使用者資料
獲取使用者資料可以使用如下介面：
在需要的位置的點選事件中寫
其中umAuthListener為授權回撥，構建如下：
//QQ授權
private void initListenr() {
authListener = new UMAuthListener() {
/**
* @desc 授權開始的回撥
* @param platform 平臺名稱
*/
@Override
public void onStart(SHARE_MEDIA platform) {
}
/**
* @desc 授權成功的回撥
* @param platform 平臺名稱
* @param action 行為序號，開發者用不上
* @param data 使用者資料返回
*/
@Override
public void onComplete(SHARE_MEDIA platform, int action, Map<String, String> data) {
Toast.makeText(LoginActivity.this, platform + "登入成功了！！！", Toast.LENGTH_LONG).show();
}
/**
* @desc 授權失敗的回撥
* @param platform 平臺名稱
* @param action 行為序號，開發者用不上
* @param t 錯誤原因
*/
@Override
public void onError(SHARE_MEDIA platform, int action, Throwable t) {
Toast.makeText(LoginActivity.this, "失敗：" + t.getMessage(), Toast.LENGTH_LONG).show();
}
/**
* @desc 授權取消的回撥
* @param platform 平臺名稱
* @param action 行為序號，開發者用不上
*/
@Override
public void onCancel(SHARE_MEDIA platform, int action) {
Toast.makeText(LoginActivity.this, "取消了", Toast.LENGTH_LONG).show();
}
};
}授權問題
第一次授權登入成功後，再次進行登入，回預設授權成功
如果需要每次登入都提示登入頁面，需要在activity中新增一下程式碼：
UMShareConfig config = new UMShareConfig();
config.isNeedAuthOnGetUserInfo(true);
UMShareAPI.get(InfoDetailActivity.this).setShareConfig(config);
目前SDK預設設定為在Token有效期內登入不進行二次授權，如果有需要每次登入都彈出授權頁面，便於切換賬號的開發者可以新增上述程式碼
好了,不多說了,開始上程式碼了
