How to Close the Android Soft Keyboard

If all the other answers here don't work for you as you would like them to, there's another way of manually controlling the keyboard.

Create a function with that will manage some of the EditText's properties:

public void setEditTextFocus(boolean isFocused) {
    searchEditText.setCursorVisible(isFocused);
    searchEditText.setFocusable(isFocused);
    searchEditText.setFocusableInTouchMode(isFocused);

    if (isFocused) {
        searchEditText.requestFocus();
    }
}

Then, make sure that onFocus of the EditText you open/close the keyboard:

searchEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (v == searchEditText) {
            if (hasFocus) {
                // Open keyboard
                ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(searchEditText, InputMethodManager.SHOW_FORCED);
            } else {
                // Close keyboard
                ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
            }
        }
    }
});

Now, whenever you want to open the keyboard manually call:

setEditTextFocus(true);

And for closing call:

setEditTextFocus(false);

Might as well use the correct flags, though.

/* hide keyboard */
((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
    .toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);

/* show keyboard */
((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
    .toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);

Example of real use

/* click button */
public void onClick(View view) {      
  /* hide keyboard */
  ((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
      .toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);

  /* start loader to check parameters ... */
}

/* loader finished */
public void onLoadFinished(Loader<Object> loader, Object data) {
    /* parameters not valid ... */

    /* show keyboard */
    ((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
        .toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);

    /* parameters valid ... */
}

from so searching, here I found an answer that works for me

// Show soft-keyboard:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

// Hide soft-keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

I'm using a custom keyboard to input an Hex number so I can't have the IMM keyboard show up...

In v3.2.4_r1 setSoftInputShownOnFocus(boolean show) was added to control weather or not to display the keyboard when a TextView gets focus, but its still hidden so reflection must be used:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
    try {
        Method method = TextView.class.getMethod("setSoftInputShownOnFocus", boolean.class);
        method.invoke(mEditText, false);
    } catch (Exception e) {
        // Fallback to the second method
    }
}

For older versions, I got very good results (but far from perfect) with a OnGlobalLayoutListener, added with the aid of a ViewTreeObserver from my root view and then checking if the keyboard is shown like this:

@Override
public void onGlobalLayout() {
    Configuration config = getResources().getConfiguration();

    // Dont allow the default keyboard to show up
    if (config.keyboardHidden != Configuration.KEYBOARDHIDDEN_YES) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(mRootView.getWindowToken(), 0);
    }
}

This last solution may show the keyboard for a split second and messes with the selection handles.

When in the keyboard enters full screen, onGlobalLayout isn't called. To avoid that, useTextView#setImeOptions(int) or in the TextView XML declaration:

android:imeOptions="actionNone|actionUnspecified|flagNoFullscreen|flagNoExtractUi"

Update: Just found what dialogs use to never show the keyboard and works in all versions:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
        WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);







The short answer

In your OnClick listener call the onEditorAction of the EditText with IME_ACTION_DONE

button.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        someEditText.onEditorAction(EditorInfo.IME_ACTION_DONE)
    }
});

The drill-down

I feel this method is better, simpler and more aligned with Android's design pattern. In the simple example above (and usually in most of the common cases) you'll have an EditText that has/had focus and it also usually was the one to invoke the keyboard in the first place (it is definitely able to invoke it in many common scenarios). In that same way, it should be the one to release the keyboard, usually that can be done by an ImeAction. Just see how an EditText with android:imeOptions="actionDone" behaves, you want to achieve the same behavior by the same means.
