Keyboard not focusing in overlay EditText. Keyboard is opening as expected but it is not working

when I type anything on keyboard then google opening. Not able to type in this EditText view.
Here I have created overlay services. and here I have written the codes for force open soft Keyboard logic.
floatingPointWidthService.java

 public void onCreate() {
super.onCreate();
//init WindowManager
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
getWindowManagerDefaultDisplay();
//Init LayoutInflater
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
addRemoveView(inflater);
addFloatingWidgetView(inflater);
implementClickListeners();
implementTouchListenerToFloatingWidgetView();
System.out.println("mFloatingWidgetView" +mFloatingWidgetView);
expandedView = mFloatingWidgetView.findViewById(R.id.expanded_container);
expandedView.setVisibility(View.VISIBLE);//set large view open
edittext1 = mFloatingWidgetView.findViewById(R.id.floating_widget_title_label);
edittext1.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInputFromInputMethod(edittext1.getApplicationWindowToken(), 1);
imm.showSoftInput(edittext1, InputMethodManager.SHOW_IMPLICIT);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

Here I have changes android:windowSoftInputMode="adjustPan"
AndroidManifest.xml

<application
android:allowBackup="true"
android:dataExtractionRules="@xml/data_extraction_rules"
android:fullBackupContent="@xml/backup_rules"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.ModFill"
tools:targetApi="31"
android:windowSoftInputMode="adjustPan"// this is for overlayKeyBoard

This is layout of overlay modal here I have added the EditText.

keyboard is opening with last line imm.toggleSoftInput method. Please tell how to type text in this EditText.

       InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInputFromInputMethod(edittext1.getApplicationWindowToken(), 1);
imm.showSoftInput(edittext1, InputMethodManager.SHOW_IMPLICIT);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

You don't need any of that. Setting the focus is sufficient. And in particular the 2nd and 4th lines here are wrong- both of them will show the keyboard, but not hook it up properly to the InputConnection and thus lead to a keyboard that appears but does nothing.
