废话不多说，直接上代码：

首先你需要知道支付宝和微信的包名和启动页的类名

调起支付宝

//调起支付宝
                    String aliPayPackageName = "com.eg.android.AlipayGphone";
                    if(AppUtils.isApplicationAvilible(getSelfActivity(),aliPayPackageName)){
                        Intent intent = new Intent(Intent.ACTION_MAIN);
                        intent.addCategory(Intent.CATEGORY_LAUNCHER);
                        ComponentName cn = new ComponentName(aliPayPackageName, "com.alipay.mobile.quinox.splash.ShareDispenseActivity");
                        intent.setComponent(cn);
                        startActivity(intent);
                    }else {
                        ToastUtils.show("您没有安装支付宝，请先安装");
                    }

 调起微信

//调起微信
                    String weChatPackageName = "com.tencent.mm";
                    if (AppUtils.isApplicationAvilible(getSelfActivity(),weChatPackageName)){
                        Intent intent = new Intent(Intent.ACTION_MAIN);
                        intent.addCategory(Intent.CATEGORY_LAUNCHER);
                        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        ComponentName cn = new ComponentName(weChatPackageName, "com.tencent.mm.ui.LauncherUI");
                        intent.setComponent(cn);
                        startActivity(intent);
                    }else {
                        ToastUtils.show("您没有安装微信，请先安装");
                    }

 判断手机有没有安装此应用方法

public static boolean isApplicationAvilible(Context context, String packageName) {
        PackageManager packageManager = context.getPackageManager();
        List<PackageInfo> installedPackages = packageManager.getInstalledPackages(0);
        if (installedPackages != null) {
            for (PackageInfo packageInfo : installedPackages) {
                if (packageInfo.packageName.equals(packageName)) {
                    return true;
                }
            }
        }
        return false;
    }
