update your xml file remove onClick from your button
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Add"
android:id="#+id/add"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sub"
android:id="#+id/sub"
/>
Problem is with your getting value from sharedPreference
String v=sharedPreferences.getInt("value","");
why are you passing string as default value and your
try this String
v = Integer.toString(sharedPreferences.getInt("value",0));
in the layout you´ve got android:onClick="add" there should be a public void add(View v) to handle the event. Do the sum inside that handler.
Please, follow the documentation
http://developer.android.com/reference/android/widget/Button.html and see the :onCLick handling.

using two buttons one for add and one for subtraction and a text view to show the numbers but when I run this program textview is not showing the numbers like after pressing add button value shoud be 1 when I use the buttons and code of java looks fine
I have tried to change their names also but its not working
here is the java code

Try this way,
you didn't set the initial value in textview like 0.
1. set initial value in text view as 0 (zero).
2. on every +/- click, first get data from textview in integer format.
3. perform +/- operation on it. Like a+1 or a-1
4. store output to textview.
Done.
Try this:
mns.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String oldStr = tv.getText().tostring();
Int oldVal = Integer.parseInt(oldStr);
Int newVal = oldVal - 1;
String newStr = String.valueOf(newVal);
tv.setText("Your Total is" + newStr);
}
});
pls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String oldStr = tv.getText().tostring();
Int oldVal = Integer.parseInt(oldStr);
Int newVal = oldVal + 1;
String newStr = String.valueOf(newVal);
tv.setText("Your Total is" + newStr);
}
});
This is my java class, MainActivity.java.
Basically I'm trying to create a button performing addition on variable i. Everything seems to be correct as far as I learnt until now. I am getting an error message on my emulator saying:

You need to call setContentView() before initializing any View.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.addButton);
final TextView txtView = (TextView) findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
i++;
txtView.setText("i value is:"+i);
}
});
}
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.

When app starts,
When validation fails,
When validation success,
Hope it helps!
I've got a TimePicker in my app and i want to add above it a CheckBox that if it checked the TimePicker won't work. This is my TimePicker: http://developer.android.com/guide/topics/ui/controls/pickers.html#TimePicker.
How can I do that? I want the timePicker to look the same as the example.
I will put here the entire project also for others to use it if they ever need it:

BestPracice add all xml text in strings.xml

Here's an functional example with all your requirements.
Tested and 100% functional :)
Put this in xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
>
<TextView
android:id="#+id/timer_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Check this to Cancel Alarm"
android:layout_above="#+id/time_picker"
android:layout_toRightOf="#+id/time_picker_checkbox"
/>
<CheckBox
android:id="#+id/time_picker_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/time_picker"
/>
<TimePicker
android:id="#+id/time_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
And Here is your java code:
package com.example.chxboxtest;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.TimePicker;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
private CheckBox cBox;
private TimePicker tPicker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initButtons();
}
private void initButtons() {
tPicker = (TimePicker) findViewById(R.id.time_picker);
cBox = (CheckBox) findViewById(R.id.time_picker_checkbox);
cBox.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.time_picker_checkbox: {
if (((CheckBox) v).isChecked()) {
Toast.makeText(this, "Deactivate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(false);
} else {
Toast.makeText(this, "Activate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(true);
}
}
break;
default:
break;
}
}
}
If you want this example in a custom dialog please let me know.
