Floating labels in android material design for editText

Hi guys Here I am going to explain Floating Labels for EditText using Android Material Design.

Step 1)AndroidManifest.xml

     <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.floatinglabel" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyMaterialTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Step 2)styles.xml

    <?xml version="1.0" encoding="utf-8"?>

  <resources>

    <style name="MyMaterialTheme" parent="MyMaterialTheme.Base">

    </style>

    <style name="MyMaterialTheme.Base"    parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

Step 3)strings.xml

  <?xml version="1.0" encoding="utf-8"?>

<resources>
    <string name="app_name">Floating Labels</string>
    <string name="action_settings">Settings</string>
    <string name="hint_name">Name</string>
    <string name="hint_email">Email</string>
    <string name="hint_password">Password</string>
    <string name="btn_sign_up">Sign Up</string>
    <string name="err_msg_name">Enter your full name</string>
    <string name="err_msg_email">Enter valid email address</string>
    <string name="err_msg_password">Enter the password</string>
</resources>

Step 4)colors.xml

<?xml version="1.0" encoding="utf-8"?>

<resources>
    <color name="colorPrimary">#457dd7</color>
    <color name="colorPrimaryDark">#443685</color>
    <color name="textColorPrimary">#FFFFFF</color>
    <color name="windowBackground">#FFFFFF</color>
    <color name="navigationBarColor">#000000</color>
    <color name="colorAccent">#800000</color>
</resources>

Step 5)build.gradle


apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.floatinglabel"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { res.srcDirs = ['src/main/res', 'src/main/res/ values-v21'] } }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
}

Validate mobile number using regular expressions in android

Hi guys Here I am going to explain how to validate  Mobile number using Regular Expressions

if(Helper.isValidMobile(MobileNo)){

    Toast.makeText(activity, "Valid", Toast.LENGTH_SHORT).show();
} else {

Toast.makeText(activity, "Not Valid", Toast.LENGTH_SHORT).show();
}

public static boolean isValidMobile(String argEditText) {
    try {
        Pattern pattern = Pattern.compile("^[+]?[0-9]{10,13}$");
        Matcher matcher = pattern.matcher(argEditText);
        return matcher.matches();
    } catch (Exception e) {
        if (ConfVars.PRINTEXECEPTOION) {
            e.printStackTrace();
        }
        return false;
    }
}

if(Helper.isValidEmail(EmailID)){

    Toast.makeText(activity, "Valid", Toast.LENGTH_SHORT).show();
} else {

Toast.makeText(activity, "Not Valid", Toast.LENGTH_SHORT).show();
}

Read incoming message automatically in android for verify OTP

Hi guys i am going to explain how to read the incoming message in android automatically to verify OTP without closing the app using the BrodcastReceiver

Step 1).IncomingSms.class

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;

public class IncomingSms extends BroadcastReceiver 
{
  @Override
public void onReceive(Context context, Intent intent) 
{

final Bundle bundle = intent.getExtras();
  try {
  if (bundle != null) 
{
   final Object[] pdusObj = (Object[]) bundle.get("pdus");
   for (int i = 0; i < pdusObj .length; i++) 
 {
    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[])                                                                                                    pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber ;
String message = currentMessage .getDisplayMessageBody();
    try
  {
   if (senderNum .equals("TA-DOCOMO")) 
   {
Otp Sms = new Otp();
Sms.recivedSms(message );
   }
}
catch(Exception e){}

}
  }

} catch (Exception e) 
{
                
 }
}

}

Step 2).Otp.class

   public class Otp extends Activity 
   {

      static EditText OtpNumber;
       protected void onCreate(Bundle savedInstanceState) 
         {
super.onCreate(savedInstanceState);
setContentView(R.layout.otp);
                OtpNumber= (EditText) findViewById(R.id.txtName);
        }

      public void recivedSms(String message) 

       {

try 
         {

OtpNumber.setText(message);

       } 

         catch (Exception e) 

             {         
                   }

      }

       }   

Step 3).Add the below permissions and receiver to your manifest file


    <uses-permission android:name="android.permission.RECEIVE_SMS" >
    </uses-permission>
    <uses-permission android:name="android.permission.READ_SMS" />
    <uses-permission android:name="android.permission.SEND_SMS" >
     </uses-permission>

    <receiver android:name=".IncomingSms">
        <intent-filter>
         <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>

         });

creating a multi select dialog box in android

1. Create a java Activity class where you want your dialog to appear. 
2. Create a field     private ArrayList mSelectedItems; for storing your array list.
3. Call launchAddItems() when you need to create the dialog.
    
4. Add the following function to create the dialog protected void
5.  launchAddItems() {
             mSelectedItems = new ArrayList();
             final String items[] = {"Android","Iphone","Nokia"};
   
             AlertDialog.Builder ab=new AlertDialog.Builder(this);
             ab.setTitle("Dialog Title")
             .setMultiChoiceItems(items, null,  new DialogInterface.OnMultiChoiceClickListener(){
   
               @Override
               public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                   if (isChecked){
                         mSelectedItems.add(which);
                   }
                   else if(mSelectedItems.contains(which)){
                       mSelectedItems.remove(Integer.valueOf(which));
                   }
               }
                
             }).setPositiveButton("OK", new DialogInterface.OnClickListener() {
                 @Override
                 public void onClick(DialogInterface dialog, int id) {
                     // User clicked OK, so save the mSelectedItems results somewhere
                     // or return them to the component that opened the dialog
                 }
             }).setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
                 @Override
                 public void onClick(DialogInterface dialog, int id) {
                 }
             });
   
             ab.create();;
            
          
             ab.show();       
       }
