Question: The value of the TextView is inserted by selecting the Item on List (ArrayList). When I close and open the app again the value in the TextView is still there. There is some way to clear the value of TextView?

Answer: 
```
TextView myTextView = (TextView) findViewById(R.id.myTextView);
myTextView.setText("");

```
For that TextView use

```
android:text=""

```

in the layout

or user textView.setText("") in the oncreate() method for the activity where textView is the TextView object retrieved from findViewById()
