Android实现第三方登录并获取到头像、名字

首先导入架包



下面还需要一个ImageLoader的依赖，用来加载图片

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

首先是清单文件里的代码

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.shiran.qqlogindemo">

<!-- QQ登录授权所需权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<!-- 注册SDKActivity -->
<activity
android:name="com.tencent.tauth.AuthActivity"
android:launchMode="singleTask"
android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tencent1105602574" /> <!-- 开放平台获取的APPID -->
</intent-filter>
</activity>
<activity android:name="com.tencent.connect.common.AssistActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:screenOrientation="portrait"/>
</application>

</manifest>

下面就是布局代码
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<Button
android:id="@+id/log"
android:text="点击登录扣扣"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

<ImageView
android:id="@+id/head"
android:layout_below="@+id/log"
android:layout_width="match_parent"
android:layout_height="200dp" />
<TextView
android:layout_below="@+id/head"
android:id="@+id/name"
android:text="name"
android:padding="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>

MainActivity代码

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.nostra13.universalimageloader.core.DisplayImageOptions;
import com.nostra13.universalimageloader.core.ImageLoader;

import com.tencent.connect.common.Cons

tants;
import com.tencent.tauth.IUiListener;
import com.tencent.tauth.Tencent;
import com.tencent.tauth.UiError;

import org.json.JSONException;
import org.json.JSONObject;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private ImageView head;
private TextView name;
private static final String TAG = "MainActivity";
private static final String APP_ID = "1105602574";//官方获取的APPID
private Tencent mTencent;
private BaseUiListener mIUiListener;
private UserInfo mUserInfo;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTencent = Tencent.createInstance(APP_ID,MainActivity.this.getApplicationContext());
Button log= (Button) findViewById(R.id.log);
head = (ImageView) findViewById(R.id.head);
name = (TextView) findViewById(R.id.name);
log.setOnClickListener(this);
DisplayImageOptions op=new DisplayImageOptions.Builder().build();
ImageLoaderConfiguration con=new ImageLoaderConfiguration.Builder(this)
.defaultDisplayImageOptions(op)
.build();
ImageLoader.getInstance().init(con);
}

@Override
public void onClick(View view) {
mIUiListener = new BaseUiListener();
//all表示获取所有权限
mTencent.login(MainActivity.this,"all", mIUiListener);

}
private class BaseUiListener implements IUiListener {

@Override
public void onComplete(final Object response) {
Toast.makeText(MainActivity.this, "授权成功", Toast.LENGTH_SHORT).show();
Log.e(TAG, "response:" + response);
final JSONObject obj = (JSONObject) response;
try {
String openID = obj.getString("openid");
String accessToken = obj.getString("access_token");
String expires = obj.getString("expires_in");
mTencent.setOpenId(openID);
mTencent.setAccessToken(accessToken,expires);
QQToken qqToken = mTencent.getQQToken();
mUserInfo = new UserInfo(getApplicationContext(),qqToken);
mUserInfo.getUserInfo(new IUiListener() {
@Override
public void onComplete(Object response) {
Log.e(TAG,"登录成功"+response.toString());
System.out.println("=========="+response);

JSONObject oo= (JSONObject) response;

try {
String   na = oo.getString("nickname");
System.out.println("===解析的名字"+na);
name.setText(na);
String url=oo.getString("figureurl_2");
System.out.println("===解析的url"+url);
ImageLoader.getInstance().displayImage(url,head);
} catch (JSONException e) {
e.printStackTrace();
}

}

@Override
public void onError(UiError uiError) {
Log.e(TAG,"登录失败"+uiError.toString());
}

@Override
public void onCancel() {
Log.e(TAG,"登录取消");

}
});
} catch (JSONException e) {
e.printStackTrace();
}
}

@Override
public void onError(UiError uiError) {
Toast.makeText(MainActivity.this, "授权失败", Toast.LENGTH_SHORT).show();

}

@Override
public void onCancel() {
Toast.makeText(MainActivity.this, "授权取消", Toast.LENGTH_SHORT).show();

}

}

/**
* 在调用Login的Activity或者Fragment中重写onActivityResult方法
* @param requestCode
* @param resultCode
* @param data
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == Constants.REQUEST_LOGIN){
Tencent.onActivityResultData(requestCode,resultCode,data,mIUiListener);
}
super.onActivityResult(requestCode, resultCode, data);
}
}

如果有那点不懂，可以参考我的上一篇“第三方QQ登录”

里面有具体的方式
