我想启动移动网络设置屏幕,以便用户可以启用/禁用3g或数据连接.任何人都可以告诉我我需要用于启动活动的意图.我用了

Intent in = new Intent(android.provider.Settings.ACTION_NETWORK_OPERATOR_SETTINGS ) 

和

Intent in = new Intent(android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS  ). 

但这两个都不起作用.

我正在尝试编辑图像.但我的setPixels出错了.

        picw = pic.getWidth();
        pich = pic.getHeight();
        picsize = picw*pich;        
        int[] pix = new int [picsize];
        pic.getPixels(pix, 0, picw, 0, 0, picw, pich);  
        pic.setPixels(pix,0,pic.getWidth(),0,0,pic.getWidth(),pic.getHeight());

但我使用setPixels获得非法状态异常

Caused by: java.lang.IllegalStateException
  at android.graphics.Bitmap.setPixels(Bitmap.java:878)
  at com.sandyapps.testapp.testapp.onCreate(testapp.java:66)

我有以下代码

my %ages = (); 

$a1 = "Michael Caine";
$a2 = "Dirty Den";
$a3 = "Angie";
$a4 = "Willy";
$a5 = "The Queen Mother";

$ages{$a1} = 39;
$ages{$a2} = 34;
$ages{$a3} = 27;
$ages{$a4} = "21 in dog years";
$ages{$a5} = 108;

print $age->{$a1};

但这不是印刷品.我不想使用键或值.如何使用'$age->{$a1}'类型语法访问哈希的内容？
