}
}
itemDetailsLinearLayout.addView(rg);
}
});
You may need to declare rg2 public at the top of the class so it can be accessed by the onCheckChangedListener

how to get the timer counted value in Android?

How to create an android mobile application that will do a counting in miliseconds (start from 0), and ask user to type"I Like to eat" in EditText and click submit. After user click submit, counting will stop and a dialog box will appear and show the counting result.
package com.example.labex4;
import java.util.Timer;

public class MainActivity extends Activity implements OnClickListener {
TextView textView1,textView2,textView3,textView4,displayValue;

Button button1;
int count = 0;
Timer T;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
T=new Timer();
T.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable()
{
#Override

{
displayValue.setText("count="+count);
count++;
}
});
}
}, 0, 1);
textView1 = (TextView)findViewById(R.id.textView1);

button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(this);
}
#Override
public void onClick(View v) {
T.cancel();
dialog.editext.setText(""+count);
}
}

Use these method to save and get values from any where in your app change parameter according to your requirment
this method to save value in shared prefrences

How to keep state of RadioButton in Android?

Hi I'm trying to develop an application which runs for every interval time, lets say for every 1 minute it will display some Toast message.
But problem is I'm using RadioButton functionality is perfect but when I tap on one radio button it will be green, but when I close and re-open the activity I'll get as none of the radio buttons selected.
Here is my MainActivity.java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radio_one_min:
if (checked)
{
//some code
}
break;
case R.id.radio_ten_min:
if (checked)
{
//some code
}
break;
case R.id.radio_disable:
if (checked)
{
//some code
}
break;
}
}
}
and here is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/radio">
<RadioButton android:id="#+id/radio_disable"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Disable"
android:onClick="onRadioButtonClicked"/>
<RadioButton android:id="#+id/radio_one_min"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1 minute"
android:onClick="onRadioButtonClicked"/>
<RadioButton android:id="#+id/radio_ten_min"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="10 minute"
android:onClick="onRadioButtonClicked"/>
</RadioGroup>
Please help me to solve this riddle.
Thanks in advance...

it is the simplest way to do so,no need of sharedpreference at all.you will get confused while using it.keep the things simple like this
public class MainActivity extends Activity {
Public static int flag=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(flag==1)
radio_one_min.setChecked(true);
else if(flag==2)
radio_ten_min.setCheckek(true);
else if(flag==3)
radio_disable.setCheckek(true);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radio_one_min:
if (checked)
{
flag =1;
//some code
}
break;
case R.id.radio_ten_min:
if (checked)
{
flag=2 ;
//some code
}
break;
case R.id.radio_disable:
if (checked)
{
flag=3;
//some code
}
break;
}
}
}
[EDITED]
I found developer.android.com/training/basics/activity-lifecycle/recreating.html document first, so my first guess was using Bundles and on Save/Resume Instace State methods. However this does not seem to work well. Here's my final attempt at a working solution (using SharedPreferences class, as suggested by some users):
import android.app.Activity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.view.View;
import android.widget.RadioButton;
public class MainActivity extends Activity {
final String PREFERENCES = "prefs";
final String RADIO_BUTTON = "prefsval";
SharedPreferences sp;
Editor e;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sp = this.getSharedPreferences(PREFERENCES, MODE_PRIVATE);
e = sp.edit();
}
#Override
protected void onResume() {
super.onResume();
if (sp != null) {
if (sp.getInt(RADIO_BUTTON, 0) != 0) {
RadioButton rb;
rb = (RadioButton) findViewById(sp.getInt(RADIO_BUTTON, 0));
rb.setChecked(true);
}
}
}
public void onRadioButtonClicked(View view) {
e.putInt(RADIO_BUTTON, view.getId());
e.apply();
}
}

Android Quote app, next and back buttons

Im trying to make a simple quote app, but every time I hit my back button after my next button it will go to the next array and not backwards. Im using an int num to keep track of with quote the user is on.
here is my back button
package me.me.quote;
public class Startme extends Activity {
Random gen= new Random();
int num;
String[] quotes = new String[15];
public void next(View N){
quotes[0]= "Love is timeless";
quotes[1]= "I hate you";
quotes[2]= "arggg!";
quotes[3]= "The end is near";
quotes[4]= "Leave be";
if(num == 5){
num =0;}
TextView text = (TextView) findViewById(R.id.Quote);
text.setText(quotes[num++]);
TextView number = (TextView) findViewById(R.id.Qn);
number.setText(""+num);
}
public void back(View B){
quotes[0]= "Love is timeless";
quotes[1]= "I hate you";
quotes[2]= "arggg!";
quotes[3]= "The end is near";
quotes[4]= "Leave be";
TextView text = (TextView) findViewById(R.id.Quote);
text.setText(quotes[num--]);
TextView number = (TextView) findViewById(R.id.Qn);
number.setText(""+num);}
public void rand(View G) {
num = gen.nextInt(5);
quotes[0]= "Love is timeless";
quotes[1]= "I hate you";
quotes[2]= "arggg!";
quotes[3]= "The end is near";
quotes[4]= "Leave be";
TextView text = (TextView) findViewById(R.id.Quote);
text.setText(quotes[num]);
