这个方法，具体代码如下：
[java]
/**
* gprs狀態
* @param getMobileDataEnabled
*
*/
public boolean getMobileDataStatus(String getMobileDataEnabled){
ConnectivityManager cm;
cm = (ConnectivityManager)this.getSystemService(Context.CONNECTIVITY_SERVICE);
Class cmClass = cm.getClass();
Class[] argClasses = null;
Object[] argObject = null;
Boolean isOpen = false;
try{
Method method = cmClass.getMethod(getMobileDataEnabled, argClasses);
isOpen = (Boolean)method.invoke(cm, argObject);
}catch(Exception e){
e.printStackTrace();
}
return isOpen;
}
/** * gprs狀態 * @param getMobileDataEnabled * @return */ public boolean getMobileDataStatus(String getMobileDataEnabled){ ConnectivityManager cm; cm = (ConnectivityManager)this.getSystemService(Context.CONNECTIVITY_SERVICE); Class cmClass = cm.getClass(); Class[] argClasses = null; Object[] argObject = null; Boolean isOpen = false; try{ Method method = cmClass.getMethod(getMobileDataEnabled, argClasses); isOpen = (Boolean)method.invoke(cm, argObject); }catch(Exception e){ e.printStackTrace(); } return isOpen; } [java]

[html]
java.lang.NoSuchMethodException: setMobileDataEnabled [boolean]
java.lang.NoSuchMethodException: setMobileDataEnabled [boolean]
后来终于网上找到一个方法 试下发现可以
[java]
private void toggleMobileData(Context context, boolean enabled){
ConnectivityManager connectivityManager =
(ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
Method setMobileDataEnabl;
try {
setMobileDataEnabl = connectivityManager.getClass().getDeclaredMethod("setMobileDataEnabled", boolean.class);
setMobileDataEnabl.invoke(connectivityManager, enabled);
} catch (Exception e) {
e.printStackTrace();
}
}
private void toggleMobileData(Context context, boolean enabled){ ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); Method setMobileDataEnabl; try { setMobileDataEnabl = connectivityManager.getClass().getDeclaredMethod("setMobileDataEnabled", boolean.class); setMobileDataEnabl.invoke(connectivityManager, enabled); } catch (Exception e) { e.printStackTrace(); } }
