Answer 1

请试一下，我已经测试了代码，并按要求工作..

关于=新的AlertDialog.Builder (AlertDialog.Builder)；

    about.setMessage("About The Giveaway");

    about.setPositiveButton("Rate", new DialogInterface.OnClickListener() 
    {
        Intent market = new Intent("android.intent.action.VIEW",Uri.parse("https://market.android.com/details?id=com.synamegames.giveaway"));

        public void onClick(DialogInterface arg0, int arg1) 
        {
                    //action
            startActivity(market);  

        }
    });

    about.setNegativeButton("Close", new DialogInterface.OnClickListener() 
    {
        public void onClick(DialogInterface arg0, int arg1) 
        {

        }
    });

    about.show();

我想你有两个问题。

首先，这里的括号不匹配：

Intent market = new Intent(
    "android.intent.action.VIEW", 
    Uri.parse("https://market.android.com/details?id=com.synamegames.giveaway");
startActivity(market);

我认为在Uri.parse调用之后需要一个提取括号，以结束意图构造函数调用：

Intent market = new Intent(
    "android.intent.action.VIEW", 
    Uri.parse("https://market.android.com/details?id=com.synamegames.giveaway"));
startActivity(market);

或者提取Uri.parse调用开始：

Uri uri = Uri.parse("https://market.android.com/details?id=com.synamegames.giveaway");
Intent market = new Intent("android.intent.action.VIEW", uri);
startActivity(market);

其次，您实际上在OnClickListener()内部子类中获得了一段代码，而不是在初始化程序块或方法中。您是想把它放到onClick处理程序中吗？

about.setPositiveButton("Rate", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface arg0, int arg1) {
        Uri uri = Uri.parse("...");
        Intent market = new Intent("android.intent.action.VIEW", uri);
        startActivity(market);
    }
});
