Android dismiss keyboard

Question

How do I dismiss the keyboard when a button is pressed?

Answer 1

you can also use this code on button click event

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Answer 2

    public static void hideSoftInput(Activity activity) {
    try {
        if (activity == null || activity.isFinishing()) return;
        Window window = activity.getWindow();
        if (window == null) return;
        View view = window.getCurrentFocus();
        //give decorView a chance
        if (view == null) view = window.getDecorView();
        if (view == null) return;

        InputMethodManager imm = (InputMethodManager) activity.getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm == null || !imm.isActive()) return;
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    } catch (Throwable e) {
        e.printStackTrace();
    }
}

Answer 3

This is my solution

public static void hideKeyboard(Activity activity) {
    View v = activity.getWindow().getCurrentFocus();
    if (v != null) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
    }
}

Answer 4

By using the context of the view, we can achieve the desired outcome with the following extension methods in Kotlin:

/**
 * Get the [InputMethodManager] using some [Context].
 */
fun Context.getInputMethodManager(): InputMethodManager {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return getSystemService(InputMethodManager::class.java)
    }

    return getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
}

/**
 * Dismiss soft input (keyboard) from the window using a [View] context.
 */
fun View.dismissKeyboard() = context
        .getInputMethodManager()
        .hideSoftInputFromWindow(
                windowToken
                , 0
        )

Once these are in place, just call:

editTextFoo.dismiss()

Answer 5

You want to disable or dismiss a virtual Keyboard?

If you want to just dismiss it you can use the following lines of code in your button's on click Event

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);

Answer 6

This Solution make sure that it hides keyboard also do nothing if it not opened. It uses extension so it can be used from any Context Owner class.

fun Context.dismissKeyboard() {
    val imm by lazy { this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
    val windowHeightMethod = InputMethodManager::class.java.getMethod("getInputMethodWindowVisibleHeight")
    val height = windowHeightMethod.invoke(imm) as Int
    if (height > 0) {
        imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0)
    }
}
