Answer 1

Just paste this to your onCreate Method in Java

final ArrayAdapter arrayAdapter = new ArrayAdapter<>(
            this, android.R.layout.simple_spinner_dropdown_item,
            getResources().getStringArray(R.array.Loc_names));

    textView1 =(AutoCompleteTextView) findViewById(R.id.acT1);
    textView1.setAdapter(arrayAdapter);

    textView1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(final View arg0) {
            textView1.setMaxLines(5);
            textView1.showDropDown();

        }
    });

And this to your Xml file...

And create an Array in string.xml under Values...

        Pakistan
        Germany
        Russia/NCR
        China
        India
        Sweden
        Australia
    

And you are good to go.
