I have a AutocompleteTextView and it works fine. When I write a word it shows the relevant result but I want to show all items without writing any word in AutocompleteTextView. How can I do that.

You need to extend AutoCompleteTextView,
> "When threshold is less than or equals 0, a threshold of 1 is > applied.".
import android.content.Context;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.widget.AutoCompleteTextView;
public class InstantAutoComplete extends AutoCompleteTextView {
public InstantAutoComplete(Context context) {
super(context);
}
public InstantAutoComplete(Context arg0, AttributeSet arg1) {
super(arg0, arg1);
}
public InstantAutoComplete(Context arg0, AttributeSet arg1, int arg2) {
super(arg0, arg1, arg2);
}
@Override
public boolean enoughToFilter() {
return true;
}
@Override
protected void onFocusChanged(boolean focused, int direction,
Rect previouslyFocusedRect) {
super.onFocusChanged(focused, direction, previouslyFocusedRect);
if (focused && getFilter()!=null) {
performFiltering(getText(), 0);
}
}
}
in xml
<AutoCompleteTextView ... /> to <your.namespace.InstantAutoComplete ... />
EDIT 1
Create new class named InstantAutoComplete then put this code into the class.
In your layout xml use this class like
then find this widget in your actity (onCreate method).

You don't need to customize your AutoCompleteTextView
. Instead just call autoCompleteTextView.showDropDown()
Whenever you need it.....cheers :)

It Works for me:
add to your object next event methods:
myView.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus)
myView.showDropDown();
}
});
myView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
myView.showDropDown();
return false;
}
});

This works for me perfectly, this is an easy way to resolve the problem:
final ArrayAdapter<String> adapter = new ArrayAdapter<>(getContext(), android.R.layout.simple_dropdown_item_1line, usernameLists);
etUsername.setThreshold(1);
etUsername.setAdapter(adapter);
etUsername.setOnTouchListener(new View.OnTouchListener() {
@SuppressLint("ClickableViewAccessibility")
@Override
public boolean onTouch(View paramView, MotionEvent paramMotionEvent) {
if (usernameLists.size() > 0) {
// show all suggestions
if (!etUsername.getText().toString().equals(""))
adapter.getFilter().filter(null);
etUsername.showDropDown();
}
return false;
}
});

You need to call requestFocus();
to show keyboard, otherwise keyboard does not pop up.
The method forcefully shows drop-down list.
autocomptv.setOnTouchListener(new OnTouchListener() {
@SuppressLint("ClickableViewAccessibility")
@Override
public boolean onTouch(View paramView, MotionEvent paramMotionEvent) {
// TODO Auto-generated method stub
autocomptv.showDropDown();
autocomptv.requestFocus();
return false;
}
});
Solution 6 - Android
you need to put those steps to make it work perfectly
1-in your xml put this
<androidx.appcompat.widget.AppCompatAutoCompleteTextView
android:id="@+id/account_type_spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="@dimen/_16sdp"
android:layout_marginTop="@dimen/_24sdp"
android:layout_marginEnd="@dimen/_16sdp"
android:background="@drawable/rounded_edt_with_border"
android:completionThreshold="0"
android:drawableRight="@drawable/ic_arrow_down"
android:hint="@string/account_type"
android:imeOptions="actionNext"
android:inputType="text"
android:padding="12dp"
android:textSize="@dimen/_15sp"
/>
you just need to set android:completionThreshold
to zero
2- in your java code put
mViewDataBinding.accountTypeSpinner.setOnFocusChangeListener((v, hasFocus) -> {
if (hasFocus)
mViewDataBinding.accountTypeSpinner.showDropDown();
});
Solution 7 - Android
use this :
text.setOnTouchListener(new View.OnTouchListener(){
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
text.showDropDown();
return false;
}
});

Nothing Custom Required.

> Suggestions are welcome.
XML:
<android.support.design.widget.TextInputLayout
android:id="@+id/tl"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatAutoCompleteTextView
android:id="@+id/autoComplete"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Hint Here" />
</android.support.design.widget.TextInputLayout>
Kotlin:
val adapter = ArrayAdapter<BusinessNoResult>(context, android.R.layout.select_dialog_item, listItems)
autoComplete.setAdapter(adapter)
//threshold specifies the minimum number of characters the user has to type in
//the
//edit box before the drop down list is shown
autoComplete.threshold = 0
//we have to add check for 0 number of character in edit text. When that
//happens, we will show pop up manually
autoComplete.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(s: Editable?) {}
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
//first check if length of input is 0
if(s?.length ?: 0 == 0){
//if you don't use handler with post delay, the API will hide pop
//up, even if you show it. There could be better ways to this, but
//I have implemented this and after 100 millis it gives an animated
//look
Handler().postDelayed({
//manually show drop down
autoComplete.showDropDown()
}, 100) // with 100 millis of delay
}
}
})
//when user focus out the view, drop down vanishes. When come back it will not
//show, so to cover this scenario add following.
autoComplete.setOnFocusChangeListener { _, hasFocus ->
//when gain focus manually show drop down
if(hasFocus)
autoComplete.showDropDown()
}

All answers are outdated. With material design, it becomes a lot easier and smooth. Make sure you put inputType as none for not to open the keyboard anymore.
XML
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/et_countries_list"
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:hint="Demo hint"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
>
<com.google.android.material.textfield.MaterialAutoCompleteTextView
android:id="@+id/countries_list"
android:layout_width="match_parent"
android:inputType="none"
android:layout_height="60dp"
/>
</com.google.android.material.textfield.TextInputLayout>
Then just add prepare your adapter and add it.
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, new String[]{
"Belgium", "France", "Italy", "Germany", "Spain", "Belgium", "France", "Italy", "Germany", "Spain"});
AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView)
findViewById(R.id.countries_list);
autoCompleteTextView.setAdapter(adapter);
You are done. It will work better than a spinner. You can set hint, error, helper as well.

If other solutions does not work for you try this instead. Popup is displayed always on click.
public class InstantAutoComplete extends AppCompatAutoCompleteTextView {
public InstantAutoComplete(Context context) {
super(context);
}
public InstantAutoComplete(Context arg0, AttributeSet arg1) {
super(arg0, arg1);
}
public InstantAutoComplete(Context arg0, AttributeSet arg1, int arg2) {
super(arg0, arg1, arg2);
}
@Override
public boolean enoughToFilter() {
return true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
performClick();
}
return super.onTouchEvent(event);
}
@Override
public boolean performClick() {
if (getFilter() != null && !isPopupShowing()) {
performFiltering(getText(), 0);
showDropDown();
}
return super.performClick();
}
}

Here an approach with onclicklistener as I found tat onTouch was a bit irritating when trying to scroll. mOccupation is the AutocompleteTextView in question.
mOccupation=(AutoCompleteTextView) findViewById(R.id.actv_occupation);
ArrayAdapter<String> occupationAdapter=new ArrayAdapter<String>
(NewClientActivity.this,
android.R.layout.simple_list_item_1,
getResources().getStringArray(R.array.occupation_array));
mOccupation.setAdapter(occupationAdapter);
mOccupation.setKeyListener(null);
mOccupation.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//mOccupation.setText(null);
((AutoCompleteTextView) view).showDropDown();
return;
}
});
I managed to put it all into a Textinputlayout with the following xml specifications:
<android.support.design.widget.TextInputLayout
android:id="@+id/lo_occupation"
android:layout_marginTop="10dp"
android:layout_gravity="center_horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="occupation"
android:focusableInTouchMode="false"<--this is the important part
android:id="@+id/actv_occupation"
android:ems="10"
android:completionThreshold="0"<--this too
/>
</android.support.design.widget.TextInputLayout>

I got a great solution to this. It's simple. This is just the drop-down and choosing from the options.
Make sure you add these two lines to XML.
android:completionThreshold="0"
android:focusableInTouchMode="false"
XML
<com.google.android.material.textfield.TextInputLayout
android:layout_marginTop="10dp"
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.AppCompatAutoCompleteTextView
android:id="@+id/select_area"
android:layout_width="match_parent"
android:layout_height="52dp"
android:padding="10dp"
android:textSize="15sp"
android:singleLine="true"
android:drawableEnd="@drawable/ic_arrow_down"
android:completionThreshold="0"
android:focusableInTouchMode="false"
android:hint="Select an Area"
android:inputType="text"
android:maxLines="1" />
</com.google.android.material.textfield.TextInputLayout>
JAVA
area_autocomplete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
area.showDropDown();
}
});
Solution 13 - Android
You could simply use this single line of code
autoCompleteTextView.setThreshold(100);
