3. Simple to use

private void init() {
        dropEditText = (DropEditText) findViewById(R.id.drop_edit_text);
        String[] strings = new String[10];
        for (int i = 0; i < 10; i++) {
            strings[i] = "美女" + i + "号";
        }
        adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, strings);
        dropEditText.setAdapter(adapter);
    }

Enter into the soft keyboard search button, etc.

1. Add imeOptions property:

<EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
