QQ登录是一个非常简单的一个第三方应用，现在，我们就来实现一个QQ登录
首先下载两个jar包 这里上传不了jar包，所以可以到我的github中下载工程中libs中的两个jar包
打代码前，先把这些东西写上：
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;
在AndroidManifest.xml中加入权限
android:name="com.tencent.tauth.AuthActivity"
android:launchMode="singleTask"
android:noHistory="true" >
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:screenOrientation="portrait"/>
Xml布局中的
xmlns:android="/apk/res/android"
xmlns:app="/apk/res-auto"
android:orientation="vertical"
xmlns:tools="/tools" android:layout_width="match_parent"
android:layout_height="match_parent" tools:context="com.bwei.czx.czx0914qq.MainActivity">
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="登录"
android:id="@+id/login"/>
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/name"/>
android:layout_width="100dp"
android:layout_height="80dp"
android:id="@+id/img"/>
下面开始MainActivity中的代码
package com.bwei.czx.czx0914qq;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
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.ImageLoader;
import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;
import com.tencent.connect.UserInfo;
import com.tencent.connect.auth.QQToken;
import com.mon.Constants;
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 {
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;
private Button login;
private TextView name;
private ImageView img;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//传入参数APPID和全局Context上下文
mTencent = Tencent.createInstance(APP_ID, MainActivity.this.getApplicationContext());
initView();
login.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mIUiListener = new BaseUiListener();
//all表示获取所有权限
mTencent.login(MainActivity.this,"all", mIUiListener);
mUserInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //获取用户信息
mUserInfo.getUserInfo(mIUiListener);
}
});
}
private void initView() {
login = (Button) findViewById(R.id.login);
name = (TextView) findViewById(R.id.name);
img = (ImageView) findViewById(R.id.img);
}
/**
* 自定义监听器实现IUiListener接口后，需要实现的3个方法
* onComplete完成 onError错误 onCancel取消
*/
private class BaseUiListener implements IUiListener {
@Override
public void onComplete(Object response) {
Toast.makeText(MainActivity.this, "授权成功", Toast.LENGTH_SHORT).show();
Log.e(TAG, "response:" + response);
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());
if(response == null){
return;
}
try {
JSONObject jo = (JSONObject) response;
Toast.makeText(MainActivity.this, "登录成功",
Toast.LENGTH_LONG).show();
String nickName = jo.getString("nickname");
String figureurl_1= jo.getString("figureurl_1");
name.setText(nickName);
ImageLoaderConfiguration configuration = new ImageLoaderConfiguration.Builder(MainActivity.this).build();
ImageLoader.getInstance().init(configuration);
ImageLoader.getInstance().displayImage(figureurl_1,img);
} catch (Exception e) {
// TODO: handle exception
}
}
@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();
}
}
@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);
}
}
下面为显示效果
qq登录完成！
