I try sleep but it freeze the application and am not getting the wifi pop up menu to connect? are there any other ways?

推荐答案

我已找到问题的解决方案在一个月前，只需要使用它线程put方法isConnected（）。
在这种情况下，我用WifiExplorerActivity来显示所有的WiFi网络，并允许用户进行连接。

I has found the solution for your problem a month ago, just use Thread put method isConnected() in it.
In this case, I use WifiExplorerActivity to display all wifi network and allow user connect to it.

        Thread t = new Thread() {
        @Override
        public void run() {
            try {
                    //check if connected!
                while (!isConnected(WifiExplorerActivity.this)) {
                    //Wait to connect
                    Thread.sleep(1000);                     
                }

                Intent i = new Intent(WifiExplorerActivity.this, MainActivity.class);
                startActivity(i);

            } catch (Exception e) {
            }
        }
    };
    t.start();

这是功能来检查无线网络连接已经与否：

And this is function to check wifi has connected or not:

  public static boolean isConnected(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager)
        context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = null;
    if (connectivityManager != null) {
        networkInfo = connectivityManager.getActiveNetworkInfo();
    }

    return networkInfo != null && networkInfo.getState() == NetworkInfo.State.CONNECTED;
}

最后，请确保您的Andr​​oidManifest.xml是这样的：

Finally, make sure your Androidmanifest.xml look like this:

    <activity android:name=".WifiExplorerActivity" >        
    <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        </intent-filter>
</activity>

此外，您还可以使用ProgressDialog等待连接。请参阅<一href="http://developer.android.com/guide/topics/ui/dialogs.html">http://developer.android.com/guide/topics/ui/dialogs.html
