Programmatically Hide the Android Soft Keyboard on Button Click and Touch Outside

Managing the Android Soft Keyboard

Working with Android applications often requires user input through the virtual keyboard. In scenarios where you have an EditText and a Button in your layout, it becomes essential to manage the keyboard effectively. Specifically, after entering text and clicking the Button, you may want to hide the keyboard to improve user experience.

This article will provide a simple and practical example of how to close the Android soft keyboard programmatically when the user interacts with areas outside the keyboard. By following the steps outlined, you can enhance the usability and interface of your Android application.

Command	Description
getSystemService	Retrieves a system-level service by name, such as the InputMethodManager for handling input methods.
hideSoftInputFromWindow	Requests to hide the soft keyboard window that is currently accepting input.
getWindowToken	Returns the window token associated with the view, necessary for hiding the keyboard.
onTouchEvent	Handles touch screen motion events, used here to hide the keyboard on touch outside.
findViewById	Finds and returns a view with the given ID, used to reference UI elements like EditText and Button.
setOnClickListener	Sets a callback that will be invoked when the view is clicked, used to trigger keyboard hiding.

Understanding the Implementation

The scripts provided demonstrate how to programmatically hide the Android soft keyboard when interacting with the UI, specifically after entering text in an field and clicking a . The Java and Kotlin examples utilize several key Android components and methods. Both scripts start by importing necessary classes such as , Context, , and various UI components. In the method, is used to link the EditText and from the layout to the code. The method is then set on the button to trigger the function when clicked.

In both implementations, the function uses to retrieve the service. The method hideSoftInputFromWindow is then called with the of the to hide the soft keyboard. Additionally, the method is overridden to ensure that the keyboard is hidden when the user touches outside the input field. This approach improves user experience by preventing the keyboard from obstructing the view unnecessarily. By using these methods and handling the touch events appropriately, the scripts efficiently manage the soft keyboard behavior in an Android application.

Using Java in Android Development

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.EditText;
 
public class MainActivity extends Activity {
    private EditText editText;
    private Button button;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        editText = findViewById(R.id.editText);
        button = findViewById(R.id.button);
 
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                hideKeyboard();
            }
        });
    }
 
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        hideKeyboard();
        return super.onTouchEvent(event);
    }
 
    private void hideKeyboard() {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
    }
}

Handling Soft Keyboard Dismissal in Android Using Kotlin

Employing Kotlin for Android App Development

import android.app.Activity
import android.content.Context
import android.os.Bundle
import android.view.MotionEvent
import android.view.View
import android.view.inputmethod.InputMethodManager
import android.widget.Button
import android.widget.EditText
 
class MainActivity : Activity() {
    private lateinit var editText: EditText
    private lateinit var button: Button
 
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
 
        editText = findViewById(R.id.editText)
        button = findViewById(R.id.button)
 
        button.setOnClickListener { hideKeyboard() }
    }
 
    override fun onTouchEvent(event: MotionEvent): Boolean {
        hideKeyboard()
        return super.onTouchEvent(event)
    }
 
    private fun hideKeyboard() {
        val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        imm.hideSoftInputFromWindow(editText.windowToken, 0)
    }
}

Exploring Advanced Techniques for Keyboard Management

Beyond the basic methods of hiding the Android soft keyboard, developers can implement more advanced techniques to enhance user experience. One such method involves using on multiple UI components to detect touch events and hide the keyboard accordingly. This approach ensures that the keyboard is hidden whenever the user interacts with any part of the screen outside the . Additionally, managing the keyboard visibility can be coupled with focusing logic, where the focus is shifted away from the to another component, prompting the keyboard to hide automatically.

Another technique is to use the on the . This listener can detect when the loses focus, and subsequently hide the keyboard. This method is particularly useful in forms or data entry applications where multiple input fields are involved. Moreover, for a more seamless user experience, developers can employ SoftKeyboardStateWatcher, a custom implementation that tracks the keyboard's visibility state changes and responds accordingly. By integrating such advanced techniques, developers can create more intuitive and user-friendly Android applications.

1. How can I detect when the keyboard is shown or hidden?
2. You can use a to track the keyboard's visibility changes.
3. Is it possible to hide the keyboard automatically when a user scrolls?
4. Yes, you can implement a on the scroll view to hide the keyboard during scrolling.
5. Can I programmatically show the keyboard when an is focused?
6. Yes, use to show the keyboard when the gains focus.
7. How do I hide the keyboard when the user presses the back button?
8. Override the method and hide the keyboard using .
9. Can I customize the keyboard layout?
10. Yes, Android allows custom keyboard layouts through .
11. What is the best way to hide the keyboard in a fragment?
12. Use to get the in a fragment.
13. How can I hide the keyboard when switching between fragments?
14. Implement a with a listener to hide the keyboard during the switch.
15. Is it possible to animate the hiding of the keyboard?
16. Yes, you can animate the view containing the to create a smooth hiding effect.

Effectively managing the Android soft keyboard is crucial for creating intuitive applications. By using getSystemService to retrieve the InputMethodManager and hideSoftInputFromWindow to hide the keyboard, developers can control when the keyboard appears and disappears. Implementing touch and click listeners further refines this control, ensuring the keyboard hides appropriately when interacting with other UI elements. These techniques enhance user experience by preventing the keyboard from obstructing important content or UI elements.
