DialogFragment focus EditText on dialog open for API 28

Question

I want to focus the first TextInputEditText in layout and automatically display the soft keyboard when dialog is shown

I'm targeting API level 28.

Layout:

        <com.google.android.material.textfield.TextInputLayout
            android:id="@+id/d_add_edit_name_til"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginStart="@dimen/activity_vertical_margin"
            android:layout_marginTop="@dimen/activity_vertical_margin"
            android:layout_marginEnd="@dimen/activity_vertical_margin"
            android:theme="@style/TextInputLayoutAppearance"
            >
            <com.google.android.material.textfield.TextInputEditText
                android:id="@+id/d_add_edit_name_et"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="User email"
                android:imeOptions="actionDone"
                android:inputType="textCapSentences"
                android:singleLine="true"
                android:focusableInTouchMode="true"
                android:focusable="true"
            >
                <requestFocus />
            </com.google.android.material.textfield.TextInputEditText>
        </com.google.android.material.textfield.TextInputLayout>

DialogFragment code:

@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
    final Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    return dialog;
}

....

@Override
public void onResume(){
    super.onResume();

    int dialogWidth = Functions.convertDpToPixel(300,activity);
    int dialogHeight = Functions.convertDpToPixel(250,activity);

    new Handler().post(() -> {
        getDialog().getWindow().setLayout(dialogWidth, dialogHeight);
    });
}

The answers from this thread helped me solve the issue for API < 28.

I know from Android 9 changes documentation that:

Additionally, activities no longer implicitly assign initial focus in touch-mode. Instead, it is up to you to explicitly request initial focus, if desired.

One of the ways to explicitly request initial focus (as discussed here) is by adding <requestFocus /> tag inside EditText, but still no success for API level 28 + DialogFragment

*Note that DialogFragment is from andoridx library (androidx.fragment.app.DialogFragment)

Anyone else having this issue?

Edit: The only way I managed to make this work is by adding the following code to onViewCreated:

    new Handler().postDelayed(() -> {
        nameEt.requestFocus();
        InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(nameEt, InputMethodManager.SHOW_IMPLICIT);
    },200);

I don't consider this to be a valid answer as using threads in this manner makes the code unpredictable. Still waiting for a good answer

Try [This code](https://stackoverflow.com/a/5106399/4168607) inside `onShowListener`. — ADM, May 28 '19 at 12:34

Use OnGlobalLayoutListener instead of Handler:

nameEt.viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener{
            override fun onGlobalLayout() {
                nameEt.viewTreeObserver.removeOnGlobalLayoutListener(this)
                nameEt.requestFocus()
            }
        })

In such case you don't need additional explicit call dialog.getWindow().setSoftInputMode(..).

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);
