Question

我在手机上有Google Play，亚马逊，三星等商店。我想让用户选择去哪个市场。如果我使用市场，默认情况下会转到Google Play应用。我想要一个列表出现。我是否必须手动检查哪些已安装并具有自定义选择屏幕？或者我可以调整当前的代码：

startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=" + appName)));

Answer 1

我有一个例子：

// get app which can open fill
public List<Map<String, Object>> getAppOpeners(Intent intent) {
    if (intent == null) {
        return null;
    }
    List<Map<String, Object>> appinfos = new ArrayList<Map<String, Object>>();
    ResolveInfo app = null;
    List<ResolveInfo> mApps = new ArrayList<ResolveInfo>();

    PackageManager pm = mContext.getPackageManager();
    mApps = pm.queryIntentActivities(intent,
            PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);// get app which can open fill
    Iterator<ResolveInfo> it = mApps.iterator();
    while (it.hasNext()) {
        Map<String, Object> item = new HashMap<String, Object>();
        app = it.next();
        if (true) {// mContext.getPackageManager().getLaunchIntentForPackage(app.activityInfo.packageName)
                    // != null
            item.put("packname", app.activityInfo.packageName);// packname of app
            item.put("appname", app.loadLabel(mContext.getPackageManager()));// name of app
            item.put("icon", app.loadIcon(mContext.getPackageManager()));// icon of app
            item.put("intent", intent);
            appinfos.add(item);
        }
    }
    //appinfos = StringSortUtil.sortString(appinfos, "appname");
    return appinfos;
}

代码用于筛选可以通过mimetype打开文件的应用程序。它可能对你有用
