Hello,

I updated this library

implementation 'androidx.appcompat:appcompat:1.3.0-rc01'

to this

implementation 'androidx.appcompat:appcompat:1.4.0-alpha01'

And there is a bug that started to appear in my code. The bug is:

 java.lang.NullPointerException: keyListener cannot be null

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:950)

This is my code

fun initChooser(textField: TextInputLayout, onClick: () -> Unit, onClear: (() -> Unit)? = null) {  
    // https://stackoverflow.com/questions/60710536/android-using-materialdatepicker-and-textinputlayout  
    textField.editText?.setKeyListener(null)  
    textField.editText?.setInputType(InputType.TYPE_NULL);  
  
    textField.editText?.setOnTouchListener(View.OnTouchListener { v, event ->  
  if (MotionEvent.ACTION_UP == event.action) onClick() // Instead of your Toast  
  false  
  })  
  
    textField.setEndIconOnClickListener {  
  onClear?.invoke()  
    }  
}

The problematic line is textField.editText?.setKeyListener(null) but I do it on purpose since I read on the stackOverflow that keaybord wont' show up after clicking. I want to use it as a read only, and when clicked to open dialog with options to choose from, therefore no keyborad. The stack overflow = https://stackoverflow.com/questions/60710536/android-using-materialdatepicker-and-textinputlayout

So probably I'm not the only one using it this way.

My xml behind this code:

<com.google.android.material.textfield.TextInputLayout  
  android:id="@+id/locationTextField"  
  style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"  
  android:layout_width="match_parent"  
  android:layout_height="wrap_content"  
  app:endIconMode="clear_text"  
  app:errorEnabled="true"  
  app:helperTextEnabled="true"  
  app:localizeText="@{`Location`}"  
  tools:hint="Location">  
  
    <com.google.android.material.textfield.TextInputEditText  
  android:layout_width="match_parent"  
  android:layout_height="wrap_content"  
  tools:text="Location 11" />  
</com.google.android.material.textfield.TextInputLayout>

I believe it has something to do with some emoji or something, which I do not want to use.

Thank you
