1、定义一个工具类（PlatformUtil）

调用方式如：Platformutil.isInstallApp(context,PlatformUtil.PACKAGE_WECHAT);// 判断微信是否安装

public class PlatformUtil {
    public static final String PACKAGE_WECHAT = "com.tencent.mm";
    public static final String PACKAGE_MOBILE_QQ = "com.tencent.mobileqq";
    public static final String PACKAGE_QZONE = "com.qzone";
    public static final String PACKAGE_SINA = "com.sina.weibo";

    // 判断是否安装指定app
    public static boolean isInstallApp(Context context, String app_package){
        final PackageManager packageManager = context.getPackageManager();
        List<PackageInfo> pInfo = packageManager.getInstalledPackages(0);
        if (pInfo != null) {
            for (int i = 0; i < pInfo.size(); i++) {
                String pn = pInfo.get(i).packageName;
                if (app_package.equals(pn))) {
                    return true;
                }
            }
        }
        return false;
    }
}

2、qq分享

/**
 * 直接分享纯文本内容至QQ好友
 * @param mContext
 * @param content
 */
public static void shareQQ(Context mContext, String content) {
    if (PlatformUtil.isInstallApp(mContext, PlatformUtil.PACKAGE_MOBILE_QQ)) {
        Intent intent = new Intent("android.intent.action.SEND");
        intent.setType("text/plain");
        intent.putExtra(Intent.EXTRA_SUBJECT, "分享");
        intent.putExtra(Intent.EXTRA_TEXT, content);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setComponent(new ComponentName("com.tencent.mobileqq", "com.tencent.mobileqq.activity.JumpActivity"));
        mContext.startActivity(intent);
    } else {
        Toast.makeText(mContext, "您需要安装QQ客户端", Toast.LENGTH_LONG).show();
    }
}
调用：

shareQQ（当前上下文，要传的文本）

shareQQ(getContext(),newsList.get(position).getTitle().concat(newsList.get(position).getUrl()));

3、微信分享

 /**
     * 直接分享文本到微信好友
     *
     * @param context 上下文
     */
    public void shareWechatFriend(Context context, String content) {
        if (PlatformUtil.isInstallApp(context, PlatformUtil.PACKAGE_WECHAT)) {
            Intent intent = new Intent();
            ComponentName cop = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareImgUI");
            intent.setComponent(cop);
            intent.setAction(Intent.ACTION_SEND);
            intent.putExtra("android.intent.extra.TEXT", content);
//            intent.putExtra("sms_body", content);
            intent.putExtra("Kdescription", !TextUtils.isEmpty(content) ? content : "");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intent);
        } else {
            Toast.makeText(context, "您需要安装微信客户端", Toast.LENGTH_LONG).show();
        }
    }

调用：

shareWechatFriend(getContext(),newsList.get(position).getTitle().concat(newsList.get(position).getUrl()));
