我正在尝试解决一个问题,在该问题中,我必须先禁用然后启用移动数据,然后之间要有一定的延迟(重置移动数据2G)。

步骤1:停用行动数据

第2步:WAITING移动数据被禁用

步骤3:延迟2秒

第4步:启用移动数据

第5步:等到启用移动数据

步骤6:继续执行程序.....

做一些研究,我想出了这个...

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button start = (Button)findViewById(R.id.button1);
        start.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                    if(!mobileDataEnabled(getApplicationContext())){
                    setMobileDataEnabled(getApplicationContext(),true);
                    Toast.makeText(getApplicationContext(), "ENABLED", Toast.LENGTH_SHORT).show();
                    }else{
                    setMobileDataEnabled(getApplicationContext(),false);
                    Toast.makeText(getApplicationContext(), "DISABLED", Toast.LENGTH_SHORT).show();
                    }

            }
        });
    }

//the method below enables/disables mobile data depending on the Boolean 'enabled' parameter.
private void setMobileDataEnabled(Context context, boolean enabled) {
        final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        Class conmanClass = null;
        try {
            conmanClass = Class.forName(conman.getClass().getName());
            final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
            iConnectivityManagerField.setAccessible(true);
            final Object iConnectivityManager = iConnectivityManagerField.get(conman);
            final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
            final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
            setMobileDataEnabledMethod.setAccessible(true);
            setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchFieldException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
// below method returns true if mobile data is on and vice versa
 private boolean mobileDataEnabled(Context context){
        boolean mobileDataEnabled = false; // Assume disabled
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        try {
            Class cmClass = Class.forName(cm.getClass().getName());
            Method method = cmClass.getDeclaredMethod("getMobileDataEnabled");
            method.setAccessible(true); // Make the method callable
            // get the setting for "mobile data"
            mobileDataEnabled = (Boolean)method.invoke(cm);
        } catch (Exception e) {
            // Some problem accessible private API
            // TODO do whatever error handling you want here
        }
        return mobileDataEnabled;
    }

上面的代码将打开/关闭移动数据,但是它发生得非常快。这样很快,移动数据甚至无法真正关闭。如何在两者之间增加延迟并实现上述步骤?任何帮助,将不胜感激。
谢谢!

最佳答案

刚放

Thread.sleep(1000);

在代码语句之间(在 setMobileData API之前)以实现延迟。 delay参数以毫秒为单位。因此,请根据您的要求进行更改。

编辑:尝试使用以下代码将延迟放入处理程序中:
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
   //Whatever you want to do
    }
}, 1000);
