How to hide soft keyboard on android after clicking outside EditText?

Question

Ok everyone knows that to hide a keyboard you need to implement:

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.hi         


        

Answer 1

A more Kotlin & Material Design way using TextInputEditText (this approach is also compatible with EditTextView)...

1.Make the parent view(content view of your activity/fragment) clickable and focusable by adding the following attributes

android:focusable="true"
android:focusableInTouchMode="true"
android:clickable="true"

2.Create an extension for all View (inside a ViewExtension.kt file for example) :

fun View.hideKeyboard(){
    val inputMethodManager = context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.hideSoftInputFromWindow(this.windowToken, 0)
}

3.Create a BaseTextInputEditText that inherit of TextInputEditText. Implement the method onFocusChanged to hide keyboard when the view is not focused :

class BaseTextInputEditText(context: Context?, attrs: AttributeSet?) : TextInputEditText(context, attrs){
    override fun onFocusChanged(focused: Boolean, direction: Int, previouslyFocusedRect: Rect?) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect)
        if (!focused) this.hideKeyboard()
    }
}

4.Just call your brand new custom view in your XML :

That's all. No need to modify your controllers (fragment or activity) to handle this repetitive case.
