Simple SMS Application In Android

Introduction

 

Today I will explain how to work with an SMS application in Android. I made my own SMS apps. I will tell you how they work and how they are made. In this application I used a layout in which I set many type layouts, all layouts and views are shown here.

 

In this application, I have used many activity classes for easy coding. Since you know how to connect activity to another, I also connect them in the manner shown here.

For this application you must have some clip art, you can save it in the drawable directory as shown below.

 

 

Step 1

 

Create a new project as shown below.

 

 

Step 2

 

Create a "create_msg_layout.xml" file as in the following coding.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="1dp" >
        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="To " />
        <EditText
            android:id="@+id/edSendNo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ems="10"
            android:inputType="number" >
            <requestFocus />
        </EditText>
        <Button
            android:id="@+id/btContactFtech"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="   "
            android:background="@drawable/contact" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="360dp"
        android:layout_above="@+id/linearLayout1"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="50dp" >
        <EditText
            android:id="@+id/edSendText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:inputType="textMultiLine" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" >
        <Button
            android:id="@+id/btSend"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Send" />
    </LinearLayout>
</RelativeLayout>

Step 3

 

Create a "inbox.xml" file as in the following coding.

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:scrollbars="vertical">
        <TextView
            android:id="@+id/tvName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_marginLeft="17dp"
            android:text=""
            android:textAppearance="?android:attr/textAppearanceLarge" />
        <TextView
            android:id="@+id/tvDate"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_below="@+id/tvName"
            android:text=""
            android:textAppearance="?android:attr/textAppearanceMedium" />
        <TextView
            android:id="@+id/tvTime"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/tvDate"
            android:layout_alignBottom="@+id/tvDate"
            android:layout_marginLeft="34dp"
            android:layout_toRightOf="@+id/tvDate"
            android:text=""
            android:textAppearance="?android:attr/textAppearanceMedium" />
        <TextView
            android:id="@+id/tvSmallMsgView"
            android:layout_width="match_parent"
            android:layout_height="20dp"
            android:layout_alignParentLeft="true"
            android:layout_below="@+id/tvDate"
            android:text=""
            android:textAppearance="?android:attr/textAppearanceSmall" />
    </RelativeLayout>

Step 4

 

Create a "list_sms_layout.xml" file, you will see the coding of this file in my attachment.

 

Step 5

 

Create a "sent_item_list.xml" file, you will see the coding of this file in my attachment.

 

Step 6

 

Create a "view_msg_layout.xml" file, you will see the coding of this file in my attachment.

 

Step 7

 

Now open the activity file "MainActivity.java" and update it with the following coding.

package c.him.smsapll;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends ListActivity {
      @Override
      protected void onCreate(Bundle savedInstanceState) {
                  super.onCreate(savedInstanceState);
            final String[] listItem = {"Create Message","Inbox","Send Item"};
/*          ArrayAdapter adapter = new ArrayAdapter(this,R.layout.list_sms_layout,R.id.textView1,listItem);
            setListAdapter(adapter);*/
            setListAdapter(new SmsArrayAdapter(this, listItem));
      }
      @Override
      protected void onListItemClick(ListView l, View v, int position, long id) {
            // TODO Auto-generated method stub
            super.onListItemClick(l, v, position, id);
            switch (position) {
            case 0:
                        Intent i1 = new Intent(this,Create_msg.class);
                        startActivity(i1);
                  break;
            case 1:
                  Intent i2 = new Intent(this,Inbox.class);
                  startActivity(i2);
                  break;
            case 2:
                  Intent i3 = new Intent(this,Sent_item.class);
                  startActivity(i3);
                  break;
            default:
                  break;
            }
      }
}

Step 8

      if(pressedKey=='0'||pressedKey=='1'||pressedKey=='2'||pressedKey=='3'||pressedKey=='4'||pressedKey=='5'||pressedKey=='6'||pressedKey=='7'||pressedKey=='8'||pressedKey=='9')
                              {
                                    myEnterNumber =myEnterNumber + pressedKey;
                                    isNumericEntered=true;
                              }
                        }
                        return false;
                  }
            });
      }
      @Override

            // TODO Auto-generated method stub
            super.onResume();
      }
      protected void onStart() {

            bSend=(Button)findViewById(R.id.btSend);
            bFetchContact=(Button)findViewById(R.id.btContactFtech);
bFetchContact.setOnClickListener(new OnClickListener() {
                  @Override

                    if (resultCode == RESULT_OK) {
                        Check_addmyNumber();
                        Uri contactUri = data.getData();
                         String[] projection = {Phone.NUMBER,Phone.DISPLAY_NAME,Phone.STATUS};
                        Cursor cursor = getContentResolver().query(contactUri, projection, null, null, null);
                        cursor.moveToFirst();

            values.put("address", number);
            values.put("body", edWrite_text.getText().toString());
        getContentResolver().insert(Uri.parse("content://sms/sent"), values);
      }
}

Step 9

 

Create a file as "ForwordMSG.java", you will see the coding of this file in my attachment.

 

Step 10

 

Create a new file "Inbox.java" with the following coding.

package c.him.smsapll;
import java.text.DateFormat;
import java.util.Date;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class Inbox extends ListActivity
{
 String[] Inbox_name = new String[100],
  Inbox_number = new String[100],
  Inbox_date = new String[100],
  Inbox_type = new String[100],
  Inbox_msg = new String[100];
 int pos = 0;
 @Override
 protected void onCreate(Bundle savedInstanceState)
 {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  Inbox_Read();
  setListAdapter(new InboxArrayAdapter(this, Inbox_name, Inbox_number, Inbox_date, Inbox_type, Inbox_msg));
 }
 @Override
 protected void onListItemClick(ListView l, View v, int position, long id)
 {
  // TODO Auto-generated method stub
  super.onListItemClick(l, v, position, id);
  Toast.makeText(Inbox.this, "Number : " + Inbox_number[position], Toast.LENGTH_SHORT).show();
  Intent intent = new Intent(this, ViewMesg.class);
  intent.putExtra("name", Inbox_name[position]);
  intent.putExtra("no", Inbox_number[position]);
  intent.putExtra("date", Inbox_date[position]);
  intent.putExtra("time", Inbox_type[position]);
  intent.putExtra("msg", Inbox_msg[position]);
  startActivity(intent);
 }
 void Inbox_Read()
 {
  Uri mSmsinboxQueryUri = Uri.parse("content://sms/inbox");
  Cursor cursor1 = getContentResolver().query(
   mSmsinboxQueryUri,
   new String[]
   {
    "_id",
    "thread_id",
    "address",
    "person",
    "date",
    "body",
    "type"
   }, null, null, null);
  startManagingCursor(cursor1);
  String[] columns = new String[]
  {
   "address",
   "person",
   "date",
   "body",
   "type"
  };
  if (cursor1.getCount() > 0)
  {
   String count = Integer.toString(cursor1.getCount());
   while (cursor1.moveToNext())
   {
    String number = cursor1.getString(cursor1.getColumnIndex(columns[0]));
    String name = cursor1.getString(cursor1.getColumnIndex(columns[1]));
    String date = cursor1.getString(cursor1.getColumnIndex(columns[2]));
    String msg = cursor1.getString(cursor1.getColumnIndex(columns[3]));
    String type = cursor1.getString(cursor1.getColumnIndex(columns[4]));
    Inbox_name[pos] = name;
    Inbox_number[pos] = number;
    if (date != null)
    {
     long l = Long.parseLong(date);
     Date d = new Date(l);
     Inbox_date[pos] = DateFormat.getDateInstance(DateFormat.LONG).format(d);
     Inbox_type[pos] = DateFormat.getTimeInstance().format(d);
    }
    else
    {
     Inbox_date[pos] = date;
     Inbox_type[pos] = type;
    }

    Inbox_msg[pos] = msg;
    pos += 1;

   }
  }
 }
}

Step 11

 

Create a new file "InboxArrayAdapter.java", you will see this coding in my attachment.

 

Step 12

 

Create a new file "SentItem.java", you will see this in my attachment.

 

Step 13

 

Create a new file "SentItemArrayAdapter.java" with the following code.

package c.him.smsapll;
import java.util.Date;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class Sent_itemArrayAdapter extends ArrayAdapter {
      private  Context context;
      private  String[] Send_item_name,Send_item_number,Send_item_date,Send_item_type,Send_item_msg;
      Sent_itemArrayAdapter(Context context,String[] Send_item_name,String[] Send_item_number,String[] Send_item_date,String[] Send_item_type,String[] Send_item_msg)
      {
      super(context,R.layout.sent_item, Send_item_number);

            this.Send_item_msg=Send_item_msg;
      }
            @Override
      public View getView(int position, View convertView, ViewGroup parent) {
                  LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                        View rowView = inflater.inflate(R.layout.sent_item, parent, false);

                  return rowView;
      }
}

Step 14

 

Create a new file "SmsArray Adapter.java", you will see this coding in my attachment in the .rar file.

 

Step 15

 

Now create a new file "Viewmsg.java" as in the following coding.

package c.him.smsapll;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class ViewMesg extends Activity{
      TextView number,date,time,msg;
      Button frd;
      @Override
      protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.view_msg_layout);
            number=(TextView)findViewById(R.id.tvNumber);
            date=(TextView)findViewById(R.id.tvDate);
            time=(TextView)findViewById(R.id.tvTime);
            msg=(TextView)findViewById(R.id.tvMsg);
            frd=(Button)findViewById(R.id.btFrd);
      }
      @Override
      protected void onStart() {
            // TODO Auto-generated method stub
            super.onStart();
            Intent i = getIntent();
            number.setText(i.getStringExtra("no"));
            date.setText(i.getStringExtra("date"));
            time.setText(i.getStringExtra("time"));
            msg.setText(i.getStringExtra("msg"));
            //startActivity(i);
            frd.setOnClickListener(new OnClickListener() {
                        @Override
                  public void onClick(View v) {
                        Intent click = new Intent(ViewMesg.this,Forward_msg.class);
                        click.putExtra("message", msg.getText());
                        startActivity(click);

                  }
            });
      }

}

Step 16

 

Now open the manifest file and update it using all the activities and permissions shown below.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="c.him.smsapll"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.READ_SMS"/>
    <uses-permission android:name="android.permission.WRITE_SMS"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/sms"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="c.him.smsapll.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>
        <activity android:name="Create_msg"
                        android:label="@string/c_msg">
        </activity>
        <activity android:name="Inbox"
            android:label="@string/Inbox_msg">
        </activity>
        <activity android:name="Sent_item"
            android:label="@string/Send_item_msg">
        </activity>
        <activity android:name="Forward_msg"
            android:label="@string/Frd_msg">
        </activity>
        <activity android:name="ViewMesg"
            android:label="@string/View_msg">
        </activity>
    </application>
</manifest>

And at last, see the output as in the following:
