推荐答案

您将要使用指定的市场协议:

You''ll want to use the specified market protocol:

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

请记住，这将在未安装Market的任何设备(例如模拟器)上崩溃.因此，我建议如下:

Keep in mind, this will crash on any device that does not have the Market installed (the emulator, for example). Hence, I would suggest something like:

try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id="+appName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id="+appName)));
}

此帮助器函数将检索所有已安装的应用程序，包括应用程序名称，程序包名称，版本号和-code以及图标.方法getPackages()返回带有所有应用程序的ArrayList.

This helper function retrieves all installed apps with the application name, package name, version-number and -code as well as the icons. The method getPackages() returns an ArrayList with all the apps.

class PInfo {
    private String appname = "";
    private String pname = "";
    private String versionName = "";
    private int versionCode = 0;
    private Drawable icon;
    private void prettyPrint() {
        Log.v(appname + "\t" + pname + "\t" + versionName + "\t" + versionCode);
    }
}

private ArrayList<PInfo> getPackages() {
    ArrayList<PInfo> apps = getInstalledApps(false); /* false = no system packages */
    final int max = apps.size();
    for (int i=0; i<max; i++) {
        apps.get(i).prettyPrint();
    }
    return apps;
}

private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
    ArrayList<PInfo> res = new ArrayList<PInfo>();
    List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
    for(int i=0;i<packs.size();i++) {
        PackageInfo p = packs.get(i);
        if ((!getSysPackages) && (p.versionName == null)) {
            continue ;
        }
        PInfo newInfo = new PInfo();
        newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
        newInfo.pname = p.packageName;
        newInfo.versionName = p.versionName;
        newInfo.versionCode = p.versionCode;
        newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
        res.add(newInfo);
    }
    return res;
}
