Closing an on-screen keyboard

For example, we should let us close an on-screen keyboard, after we log in successfully.

In that case, We can close the keybord programmatically. 

==== MainActivity.java ====

package com.example.samplekeypad;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.inputmethod.InputMethodManager;

import android.widget.Button;

import android.widget.Toast;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button btnCloseKeypad = (Button)findViewById(R.id.btnCloseKeyPad);

btnCloseKeypad.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

/**

* We can close the on-screen keyboard by using InputMethodManager.

*/

InputMethodManager inputManager = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);

inputManager.hideSoftInputFromWindow(v.getWindowToken(), 0);

Toast.makeText(getBaseContext(), "스크린 키보드를 닫습니다.", Toast.LENGTH_SHORT).show();

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

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

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

return true;

}

}

: We can close an on-screen keyboard by calling hideSoftInputFromWindow() method in InputMethodManager Class.
