Well, my application would display wifi information (still work in progress for this) and set with a time picker when the wifi turns on. The problem is that i don't know how to connect the button inside the dialog of the picker "set" at the AlarmManager method. This is the code
package com.pkg.androidmemoryinfo;
import android.app.Activity;
import android.app.ActivityManager;
import android.app.ActivityManager.MemoryInfo;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.content.Context;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.Toast;
import java.util.Calendar;
public class MainActivity extends Activity implements OnClickListener {
private Button mTimeButton;
private Calendar mCalen;
private int hourOfDay;
private int minute;
private int ampm;
private static final int Time_PICKER_ID = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTimeButton = (Button) findViewById(R.id.time_button);
mCalen = Calendar.getInstance();
hourOfDay = mCalen.get(Calendar.HOUR_OF_DAY);
minute = mCalen.get(Calendar.MINUTE);
ampm = mCalen.get(Calendar.AM_PM);
mTimeButton.setOnClickListener(this);
// Creating a memory_info Object
MemoryInfo memory_info = new MemoryInfo();
// Using Activity Manager System Service
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
activityManager.getMemoryInfo(memory_info);
// Assign Memory Value to free_memory Variable
long free_memory = memory_info.availMem / 1048576L;
// Display free Ram Memory
TextView memoryInfoView = (TextView) findViewById(R.id.device_memory_status_txt);
memoryInfoView.setText("Free RAM Memory :-"+ free_memory + " MB");
}
public void run() {
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo info = wifi.getConnectionInfo();
String ssid = info.getSSID();
TextView ssidTextView = (TextView) findViewById(R.id.wifiSSID);
ssidTextView.setText(ssid);
}
@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
switch (id) {
case Time_PICKER_ID:
return new TimePickerDialog(this, TimePickerListener,
hourOfDay, minute, false);
}
return null;
}
private TimePickerDialog.OnTimeSetListener TimePickerListener =
new TimePickerDialog.OnTimeSetListener() {
// while dialog box is closed, below method is called.
public void onTimeSet(TimePicker view, int hour, int minute) {
mCalen.set(Calendar.HOUR_OF_DAY, hour);
mCalen.set(Calendar.MINUTE, minute);
int hour12format = mCalen.get(Calendar.HOUR);
hourOfDay = mCalen.get(Calendar.HOUR_OF_DAY);
minute = mCalen.get(Calendar.MINUTE);
ampm = mCalen.get(Calendar.AM_PM);
String ampmStr = (ampm == 0) ? "AM" : "PM";
// Set the Time String in Button
TextView dateInfoView = (TextView) findViewById(R.id.dateinfo);
dateInfoView.setText("L'attivazione del Wi-Fi è impostata per le ore: " + hour12format + " : " + minute + " / " + ampmStr);
/// Here is the problem: Where have i to put this? ///
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
}
};
@SuppressWarnings("deprecation")
@Override
public void onClick(View v) {
showDialog(Time_PICKER_ID);
}
}
As you can see i don't know how put the wifi control. How can i do it? How can i create an AlarmManager with my code? I Need an example if possible. Thanks
This is one example of time picker that I think you can use.

-------------Manifest.xml-----------
**<activity

Dont forget to add TimePicker class as activity. BestPracice add all xml text in strings.xml
Cheers
