there is better way to do that? like more efficient? ineed to do this code, but my moderator tell me to do this with more efficient way thx for help:

onCreate:(starters...)

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    layout = new Layout();
    Event event = new Event(layout);
}

layout+event:

  class Layout
{
     public Layout()
    {
         txtName = (EditText)findViewById(R.id.txtName);
         btnSerch = (Button)findViewById(R.id.btnSerch);
        group1 = (RadioGroup)findViewById(R.id.group1);
    }
    RadioGroup group1;
    EditText txtName;
    Button btnSerch;
}

class Event
{
    public Event(Layout layout)
    {
        layout.btnSerch.setOnClickListener(new start_Serch());
    }
}

class start_Serch implements OnClickListener
{
    @Override
    public void onClick(View view)
    {
        Serch(view, layout);
    }
    Layout layout;
}

Main goal: (the main commands of the application)

void Serch(View v, Layout layout)
{
    Uri Contacts = android.provider.ContactsContract.Contacts.CONTENT_URI;

    Cursor C = getContentResolver().query(Contacts, null, null, null, null);

    if(C != null)
    {
        if(C.moveToFirst())
        {
            do
            {
                String display_ContactsName = getValue(C, android.provider.ContactsContract.Contacts.DISPLAY_NAME);

                if (Check(display_ContactsName, C) == true)
                {
                    break;
                }

            }while (C.moveToNext());
        }
    }
}

get value+Chack: (assist commands..)

private String getValue(Cursor cursor, String name)
{
    return cursor.getString(cursor.getColumnIndex(name));
}
private boolean Check(String Name, Cursor C)
{
    boolean Found = false;
    int id = layout.group1.getCheckedRadioButtonId();
    switch (id)
    {
        case -1:
            break;
        case R.id.fullName:
            if (layout.txtName.getText().toString().equals(Name))
            {
                AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);

                alert.setTitle("Hey This Contact Is in the LIST!!! yay you are the best lasy man EVER SO G***");

                alert.setMessage("The contact "+Name+" was found in this phone... oh ya");

                alert.setPositiveButton("ok",new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialogInterface, int i)
                    {
                    }
                });
                alert.show();
                Found = true;
            }
            break;
        case R.id.Contane:
            if ( Name.toLowerCase().contains ( layout.txtName.getText ().toString ().toLowerCase()))
            {
                AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);

                alert.setTitle("this is the first result for the name that you typed");

                alert.setMessage("The contact "+Name+" was found in this phone... oh ya");

                alert.setPositiveButton("ok",new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialogInterface, int i)
                    {
                    }
                });
                alert.show();
                Found = true;
                break;
            }
    }

     if (C.isLast() == true&&layout.txtName.getText().toString().equals(Name) == false&& Name.toLowerCase().contains ( layout.txtName.getText ().toString ().toLowerCase()) == false)
    {
        AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);

        alert.setTitle("Hey This Contact Is NOT in the LIST!!!");

        alert.setMessage("The contact/part of "+layout.txtName.getText().toString()+" was not found in this phone...");

        alert.setPositiveButton("ok",new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialogInterface, int i)
            {
            }
        });
        alert.show();
    }
    return Found;
