Show all items in AutocompleteTextView without writing text

Question

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 AutocompleteTextVi

Answer 1

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>

Answer 2

You could simply use this single line of code

autoCompleteTextView.setThreshold(100);

Answer 3

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;
        }
    });

Answer 4

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;
    }
});

Answer 5

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();
    });

Answer 6

use this :

 text.setOnTouchListener(new View.OnTouchListener(){


            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                // TODO Auto-generated method stub
                text.showDropDown();
                return false;
            }
            });
