I got solution for my question.Without using softkeyboard I developed the fixed custom keyboard in my activity

public class keyboardActivity1 extends Activity {

    private EditText et;
    Keyboard keyboard;
    KeyboardView keyview;
    boolean caps = false;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_keyboard1);
        //create Keyboard object
        keyboard = new Keyboard(this, R.xml.keypad);
        //create KeyboardView object
        keyview = (KeyboardView) findViewById(R.id.customkeyboard);
        //attache the keyboard object to the KeyboardView object
        keyview.setKeyboard(keyboard);
        //show the keyboard
        keyview.setVisibility(KeyboardView.VISIBLE);
        //take the keyboard to the front
        keyview.bringToFront();
        //register the keyboard to receive the key pressed
        keyview.setOnKeyboardActionListener(new KeyList());
        et = (EditText) findViewById(R.id.txt_edit);

    }

    class KeyList implements KeyboardView.OnKeyboardActionListener {
        public void onKey(View v, int keyCode, KeyEvent event) {

        }
        public void onText(CharSequence text) {

        }

        public void swipeLeft() {

        }

        @Override
        public void onKey(int primaryCode, int[] keyCodes) {

        }

        public void swipeUp() {

        }

        public void swipeDown() {

        }

        public void swipeRight() {

        }

        // @TargetApi(Build.VERSION_CODES.KITKAT)
        public void onPress(int primaryCode) {
            // InputConnection ic = getCurrentInputConnection();


            if (primaryCode == -5) { //take the last character out when delete button is pressed.
                String text = et.getText().toString();
                if (et.length() > 0) {
                    text = text.substring(0, text.length() - 1);
                    et.setText(text);
                    et.setSelection(text.length());
                }
            } else if (primaryCode == -1) {

                caps = !caps;
                keyboard.setShifted(caps);
                keyview.invalidateAllKeys();
               // char code = (char) primaryCode;
                //  if (Character.isLetter(code) && caps) {
               // code = Character.toUpperCase(code);
              //  et.append("" + code);


            } else if (primaryCode == 10) {
                String text = et.getText().toString();
                et.setText(text);

            } else {
                char code = (char) primaryCode;

                // else if(Character.isLetter(code) && caps)){


                if (Character.isLetter(code) && caps) {
                    // char code = (char) primaryCode;

                    code = Character.toUpperCase(code);
                    //et.setText(code);
                    et.append(String.ValueOf(code));
                } else { // char code = (char) primaryCode;
                    code = Character.toLowerCase(code);
                    et.append(String.ValueOf(code));
                }
            }
        }

        @Override
        public void onRelease(int i) {

        }
    }

    @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_keyboard_activity1, menu);
        return true;
    }

}

Answer 2

We have 2 ways to hidden the keyboard:

1: You can set it always hidden when the activity running

android:windowSoftInputMode="stateHidden|stateAlwaysHidden"

2: You can using java code to hidden the keyboard

public static void hideKeyboardMachine(Activity activity) {
    InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    View view = activity.getCurrentFocus();
    if (view != null) {
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

I hope it helpful for you :)
