programically click EditText

I would like to programmatically click an editText once a button has been pressed.
When a radio button "pitot_area" is selected, I want the editText associated with this selection to be programmatically clicked, so the user has one less "click" on the screen and it happens automatically.
So far I have tried
performClick()
callOnClick()
requestFocus()
the area i would like this code to be within is below:
root.pitot_area.setOnClickListener {
setAreaLabels(root)
evNodeItem.kvParams = false
evNodeItem.PitotRectArea = false
evNodeItem.PitotRoundArea = false
evNodeItem.areaParams = true
root.area_edit_text.requestFocus()
another method I have tried is
root.area_edit_text.setFocusableInTouchMode(true);
root.area_edit_text.setFocusable(true);
root.area_edit_text.requestFocus();
for the above lines of code, I have in the .xml file for the editText
android:focusable="false"
android:focusedByDefault="false"
An error does not show and the code builds, it seems this code is not read in kotlin? Does anyone have any ideas on how to do this? Thanks!
edit
ive looked at-> Focus Edit Text Programmatically (Kotlin) question sugggested below and was unable to implement it for my code.

To set direct focus to the EditText you have to open keyboard after setting focus to the EditText.
write this lines into your button click:
For Activity:
button.setOnClickListener {
editText.isFocusableInTouchMode = true
editText.requestFocus()
val inputMethodManager: InputMethodManager = getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.toggleSoftInputFromWindow(llMainView.applicationWindowToken, InputMethodManager.SHOW_FORCED, 0)
}
For Fragment:
button.setOnClickListener {
editText.isFocusableInTouchMode = true
editText.requestFocus()
val inputMethodManager: InputMethodManager = activity!!.getSystemService(AppCompatActivity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.toggleSoftInputFromWindow(llMainView.applicationWindowToken, InputMethodManager.SHOW_FORCED, 0)
}

How to display input method picker list title and summary in textview android?

i am sing keyboard view to select. After selecting the keyboard, how to display the selected keyboard text in textview android?
i can display only language but how to display the Title and summary for change keyboard?
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
#RequiresApi(api = Build.VERSION_CODES.N)
#Override
public void onClick(View view) {
InputMethodManager imm = (InputMethodManager) MainActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showInputMethodPicker();
InputMethodSubtype ims = imm.getCurrentInputMethodSubtype();
String localeString = ims.getLocale();
Locale locale = new Locale(localeString);
String currentLanguage = locale.getDisplayLanguage();
Toast.makeText(MainActivity.this,currentLanguage,Toast.LENGTH_SHORT)
.show();
//Title and summary for change keyboard need to display
}
});
}
}

there are two ways to handle this, the simplest way is use a non-size-edittext
don't hide the text view, if it hide then edtTxt.getText().toString() gets empty always
<EditText
android:id="#+id/edtTxt"
android:layout_width="0px"
android:layout_height="0px" />
So that user can't see that. and on click of button
edtTxt.requestFocus();
edtTxt.setText("");
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInputFromWindow(edtTxt.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED,
0);
Now edtTxt.getText().toString() giving text.
Without an EditText you're going to have a hard time.
An InputMethod needs to be connected to a view. Whatever view you use, you need to override onCreateInputConnection to return a custom InputConnection object that at a minimum implements commitText (for word input), deleteSurroundingText (for deletes), and sendKeyEvent (for keyboards that assume you're in dumb mode), and all of the completion functions. Input connections are complicated things and you'll screw up 3rd party keyboards like Swiftkey and Swype if you don't get it right. I really don't suggest doing this.
If you want to do this your best chance of getting it right is to claim your window is a TYPE_NULL input type. Most keyboards will dumb themselves down and assume you only accept the simplest commands in that mode. But you can't count on it.
I'd look at the InputConnection returned by the EditText class and copy as much of it as possible.

Is there any way to prevent a keyboard to show up in android

My activity has a single text field, which is editable, I want it so that when the activity is started the keyboard doesn't automatically start up, it should come up only when the user clicks on the editTiext field.
Any help?

In your manifest file add this line android:windowSoftInputMode="stateHidden"to your activity!

It seems like when your activity starts your TextView (since you said text field I suppose you have a TextView but the property exists on other views as well) receives automatically focus. Try looking at the TextView properties to find one that is about the object receiving focus.

public static void hideKeyboard(Context mContext){
//Hide a keypad write down on onCreate
((Activity) mContext).getWindow()
.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
public static void showKeyboard(Context mContext,EditText edittext){
//Show a Keyboard when you click on Edittext
InputMethodManager mgr = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(edittext, InputMethodManager.SHOW_FORCED);
}

Make a custom keyboard in Android having the same behavior as the soft keyboard

So, today I decided to try out Android, so please understand that I am a beginner in it.
What I want to achieve right now is to have a EditText, and a set of buttons to be used to enter data into the EditText.
What I've done currently is stick a set of button widgets in the XML layout, and I use this code to make the buttons insert stuff into the EditText:
final EditText inputline = (EditText) findViewById(R.id.textentry);
final Button my_button = (Button) findViewById(R.id.my_btn);
my_button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
inputline.append("a");
}
});
This kind of works, but I need help with a few issues:
it always appends the character at the end of the string, not at the current cursor position
similarly, when I call inputline.selectAll() and press my button, it inserts the text at the end of the string again; whereas I want it to delete the text first (as it's selected) and then insert the character
it seems tedious to write all that code for each of the buttons I have. Is there a better way to do this altogether?
Thanks for your help!

I have now pretty much solved by replacing inputline.append("a"); etc. with my custom function, lineInsert(), which you can see below.
public void lineInsert(CharSequence text) {
final EditText inputline = (EditText) findViewById(R.id.textentry);
int start = inputline.getSelectionStart();
int end = inputline.getSelectionEnd();
inputline.getText().replace(Math.min(start,end), Math.max(start,end), text, 0, text.length());
inputline.setSelection(inputline.getSelectionEnd());
}
This has the same behavior as the soft keyboard.

Defining EditText imeOptions when using InputMethodManager.showSoftInput(View, int, ResultReceiver)

In my application I have a custom view which requires some text input. As the view in itself doesn't contain any actual views (it's a Surface with custom drawing being done), I have a FrameLayout which contains the custom view and underneath it an EditText -view. When the user does a specific action, the custom view is hidden and the EditText takes over for user input. This works fine, but android:imeOptions seem to be ignored for this view. I'm currently doing this:
InputMethodManager inputMethodManager = (InputMethodManager)parent.getSystemService(Context.INPUT_METHOD_SERVICE);
EditText t = (EditText)parent.findViewById(R.id.DummyEditor);
t.setImeOptions(EditorInfo.IME_ACTION_DONE);
inputMethodManager.showSoftInput(t, 0, new ResultReceiver(mHandler) {
#Override
protected void onReceiveResult(
int resultCode, Bundle resultData) {
// We're done
System.out.println("Editing done : " +
((EditText)parent.findViewById(R.id.DummyEditor)).getText());
}
}
);
It seems that the setImeOptions(EditorInfo.IME_ACTION_DONE) has no effect. I've also tried adding the option to the layout XML with android:imeOptions="actionDone". No help.
Any ideas?

this post looks like will answer your question:
How do I handle ImeOptions' done button click?
