TL;DR: You choose an option from (a) my listview. Then, you change your mind and type something in (b) my edit text. How do I clear your listview selection and only show your edittext? (and vice versa)

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_selected="true"
        android:drawable="@color/colorPrimary"/>
    <item
        android:state_selected="false"
        android:drawable="@color/windowBackground" />
</selector>

e.setOnEditorActionListener(new TextView.OnEditorActionListener()
        {
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

                for(int i=0; i<=5; i++){
                                listView.setItemChecked(i, false);
                }
                listView.clearChoices();
                listView.requestLayout()
                adapter.notifyDataSetChanged()
             }
        }

<EditText
                android:id="@+id/editText"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignBaseline="@+id/textView4"
                android:layout_alignBottom="@+id/textView4"
                android:layout_toEndOf="@+id/textView4"
                android:layout_toRightOf="@+id/textView4"
                android:color="@color/colorPrimary"
                android:imeOptions="actionDone"
                android:inputType="text"
                android:textColor="@color/textColorPrimary"
                android:textColorHint="@color/colorPrimary" />

    <ListView
        android:id="@+id/listview"
        android:layout_width="wrap_content"
        android:layout_height="250dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/toolbar"
        android:background="@drawable/bg_key"
        android:choiceMode="singleChoice"
        android:listSelector="@color/colorPrimary">

    </ListView>

长话短说

    public void hideListViewSelector() {
        mListView.getSelector().setAlpha(0);
    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        if (mListView.getSelector().getAlpha() == 0) {
            mListView.getSelector().setAlpha(255);
        }
    }

<ListView

            view.setBackgroundResource(R.drawable.list_item_bg);
        }
        return view;
    }
};

<FrameLayout
