Show keyboard when Activity start

i am currently working on a Search Activity, and i need to show the keyboard when this activity is started, and focus to the EditText. and to perform this task its simple just use this code

EditText keywordEdit = (EditText) findViewById(R.id.keywordEdit);
keywordEdit.setFocusable(true);
keywordEdit.requestFocus();

InputMethodManager imm = (InputMethodManager) SearchActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);

if(imm != null){ 
	imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0); 
}

hopefully it helps
