Android show softkeyboard with showSoftInput is not working?

When the activity launches It seems that the keyboard is initially displayed but hidden by something else, because the following works (but is actually a dirty work-around):

First Method

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
editText.postDelayed(new Runnable()
{
    @Override
    public void run()
    {
        editText.requestFocus();
        imm.showSoftInput(editText, 0);
    }
}, 100);

Second method

in onCreate to launch it on activity create

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() 
    {
    //  InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    //    inputMethodManager.toggleSoftInputFromWindow(EnterYourViewHere.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);

        if (inputMethodManager != null)
        {
            inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
        } 
    }
}, 200);

Third Method
ADD given code to activity tag in Manifest. It will show keyboard on launch, and set the first focus to your desire view.

android:windowSoftInputMode="stateVisible"
