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。谁能告诉我我需要使用哪个意图来启动活动。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。

它们不起作用，因为我认为在 2.3 中修复了一个错误。

见https://review.source.android.com/#/c/22229/

您可以使用（对于 NETWORK_OPERATOR_SETTINGS）绕过它

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.phone", "com.android.phone.NetworkSetting");
startActivity(intent);

替换NetworkSetting为SettingsDATA_ROAMING_SETTINGS

错误打开移动网络设置菜单中描述了另一种类似的解决方案

更新

我最近对此进行了测试，似乎直到 API 级别 15 仍需要此解决方法。由于 API 级别 16，问题中的意图似乎可以正常工作。

我会尽力回答，尽管这个问题是几年前提出的。如果您要做的是启动“数据使用”屏幕。试试这段代码。它对我有用。

Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("com.android.settings",
                "com.android.settings.Settings$DataUsageSummaryActivity"));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);

有两种可能：

它调出整体网络设置，用户可以从那里转到移动网络

startActivity(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS));

如Zharf建议：

它调出移动网络设置，用户可以从那里启用网络

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.phone","com.android.phone.NetworkSetting");
startActivity(intent);

在我的情况下（android 9），这个意图直接落在移动数据设置上：

val intent = Intent(Settings.ACTION_DATA_ROAMING_SETTINGS)
context.startActivity(intent)

您可以将它用于 Android API 29，它显示了一个用于切换 Wifi/mobile-data 的小 UI：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    startActivity(Intent(android.provider.Settings.Panel.ACTION_INTERNET_CONNECTIVITY))
}

在此处输入图像描述

https://developer.android.com/reference/android/provider/Settings.Panel#ACTION_INTERNET_CONNECTIVITY

专注于移动数据设置：

startActivity(Intent(android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS))

专注于 Wifi 设置：

startActivity( Intent(android.provider.Settings.ACTION_WIFI_SETTINGS))
