以编程方式启动移动网络设置屏幕 [英] Launching mobile network settings screen programmatically

问题描述

我要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。有人可以告诉我开始活动时需要使用哪种意图。我使用的

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

和

  =新的Intent（android.provider.Settings.ACTION_DATA_ROAMING_SETTINGS）。 
  

但两者都不起作用。

解决方案

它们不起作用，因为我认为在2.3中已修复了一个错误。

请参见 https://review.source.android.com/#/c/22229/

您可以使用（对于NETWORK_OPERATOR_SETTINGS）跳过此操作

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

用 NetworkSetting >针对DATA_ROAMING_SETTINGS的设置

还有另一种类似的解决方案，在打开移动网络设置菜单时出错

更新

我最近对此进行了测试，看来直到API级别15仍需要此解决方法。自API级别16起，问题的意图似乎可以正常工作。

I want to launch mobile network settings screen, so that user can enable/disable 3g or data connection. Can anybody tell me which intent I need to use for starting activity. I used

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

and

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

but both of these didn't work.

解决方案

They won't work because there was a bug that was fixed I think in 2.3.

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

You can bypass this using (for NETWORK_OPERATOR_SETTINGS)

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

Replace NetworkSetting with Settings for DATA_ROAMING_SETTINGS

there's another similar solution described in Error opening mobile network settings menu

UPDATE

I recently tested this and it seems that this workaround is still necessary up to API level 15. Since API level 16 the intents in the question seem to work correctly.
