Custom EditText is not showing keyboard on focus

It's an old question but if someone cares, the problem is on the implementation of the constructor:

public CustomFontEditText(Context context, AttributeSet attrs) {    this(context, attrs, 0);    this.context = context;}

The last argument ("defStyle") which you set as 0, should be the default style for an EditText. If you take a look at the same constructor on the EditText class:

public EditText(Context context, AttributeSet attrs) {    this(context, attrs, com.android.internal.R.attr.editTextStyle);}

As you can see, the default style for an EditText should be used, so your constructor should look like this:

public CustomFontEditText(Context context, AttributeSet attrs) {    this(context, attrs, android.R.attr.editTextStyle);    this.context = context;}

Make custom EditText with Kotlin to fix focus problem:

class MyEditText @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = android.R.attr.editTextStyle) : AppCompatEditText(context, attrs, defStyleAttr) { init {    doSomething(context) } private fun doSomething(context: Context) {   // TODO Set your custom font or whatever you need }}

add this

 android:focusable="true"
