Hi , Now I am moving towards new Program that is Android Studio Temperature Conversion, a very basic converter which will look as below :

Android Studio Temperature Convertor

Step 1 : Create a new project named as Temperature Convertor Android Studio

Android Studio Temperature Converter

Step 2 : activity_temperature_main.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"

tools:context=".MainActivity"

android:background="@color/myColor">

<EditText

android:id="@+id/editText1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentLeft="true"

android:layout_alignParentTop="true"

android:ems="10"

android:inputType="numberSigned|numberDecimal" />

<RadioGroup

android:id="@+id/radioGroup1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/editText1"

android:layout_below="@+id/editText1" >

<RadioButton

android:id="@+id/radio0"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:checked="true"

android:text="@string/celsius" />

<RadioButton

android:id="@+id/radio1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/fahrenheit" />

</RadioGroup>

<Button

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/radioGroup1"

android:layout_below="@+id/radioGroup1"

android:layout_marginTop="22dp"

android:text="@string/calc"

android:onClick="onClick" />

</RelativeLayout>

Step 3 : TemperatureMainActivity.java

package com.example.sony.temperatureconvertorandroidstudio;

import android.support.v7.app.ActionBarActivity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.widget.EditText;

import android.widget.RadioButton;

import android.widget.Toast;

public class TemperatureMainActivity extendsActionBarActivity {

private EditText text;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_temperature_main);

text = (EditText) findViewById(R.id.editText1);

}

public void onClick(View view) {

switch (view.getId()) {

case R.id.button1:

RadioButton celsiusButton = (RadioButton) findViewById(R.id.radio0);

RadioButton fahrenheitButton = (RadioButton) findViewById(R.id.radio1);

if (text.getText().length() == 0) {

Toast.makeText(this, "Please enter a valid number",

Toast.LENGTH_LONG).show();

return;

}

float inputValue = Float.parseFloat(text.getText().toString());

if (celsiusButton.isChecked()) {

text.setText(String

.valueOf(ConverterUtil.convertFahrenheitToCelsius(inputValue)));

celsiusButton.setChecked(false);

fahrenheitButton.setChecked(true);

} else {

text.setText(String

.valueOf(ConverterUtil.convertCelsiusToFahrenheit(inputValue)));

fahrenheitButton.setChecked(false);

celsiusButton.setChecked(true);

}

break;

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.menu_temperature_main, menu);

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

// Handle action bar item clicks here. The action bar will

// automatically handle clicks on the Home/Up button, so long

// as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

//noinspection SimplifiableIfStatement

if (id == R.id.action_settings) {

return true;

}

return super.onOptionsItemSelected(item);

}

Step 4 : ConvertorUtil.java

package com.example.sony.temperatureconvertorandroidstudio;

/**

* Created by sony on 4/15/2015.

public class ConverterUtil {

public static float convertFahrenheitToCelsius(float fahrenheit) {

return ((fahrenheit - 32) * 5 / 9);

}

// converts to fahrenheit

public static float convertCelsiusToFahrenheit(float celsius) {

return ((celsius * 9) / 5) + 32;

}

Button Example Android Studio

Hi Today's my post on How to use Button in Android .Button is a UI widget . If you are very beginner first go through my first example of Android Hello World which helps you how to run a very basic program in android.

Step 1 : Create a new Project

Button Android Studio

Step 2: Create a new activity.I named it as Button Activity

Button Android Studio

Step 3:

Now you can see screen as activity_button.xml. Just drag two edittext widget and one button .

Go to properties and change name as ADD or anything you want .

Button Android Studio

Code of activity_button.xml is as shown below :

<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:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".ButtonActivity">

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/editText1"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="41dp"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/editText2"
android:layout_below="@+id/editText1"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="45dp"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add"
android:id="@+id/button"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>

Step 4:

In activity class ButtonActivity.java we need to make a event listener for ADD button which will take values from both edittext widgets ,add them and show result on toast.

Code for ButtonActivity.java

package com.example.sony.androidbuttonexample;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class ButtonActivity extends ActionBarActivity {
private Button btnSum;
private EditText edt1,edt2;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_button);

addbuttonlistener();
}

public void addbuttonlistener()
{

btnSum =(Button)findViewById(R.id.button);
edt1 = (EditText)findViewById(R.id.editText1);
edt2 = (EditText)findViewById(R.id.editText2);

btnSum.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

int s1=Integer.parseInt(edt1.getText().toString());
int s2=Integer.parseInt(edt2.getText().toString());

int s3= s1 + s2;

Toast.makeText(getApplicationContext(),String.valueOf(s3),Toast.LENGTH_LONG).show();

}
});
}

}

Output :
