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?

Set the TextView text programmatically You can also set the TextView 's text attribute programmatically in your Activity class. Inside the Activity class where you want to set the text, find the TextView using the findViewById() method. Then, use the setText() method to set the new text.
getLineCount(); if ( lines > 0) if ( l. getEllipsisCount(lines-1) > 0) Log. d(TAG, "Text is ellipsized"); } } });
A TextView displays text to the user and optionally allows them to edit it. A TextView is a complete text editor, however the basic class is configured to not allow editing.
You are applying to your TextView a compound Drawable on the right.. to make the three dots appear in this scenario, you have to apply a android:drawablePadding="{something}dp" attribute to the TextView as well. Hope it helps!
EditText is used for user input. TextView is used to display text and is not editable by the user. TextView can be updated programatically at any time.
TextView myTextView = (TextView) findViewById(R.id.myTextView);
myTextView.setText("");
If you would like for your hints to show in the fields, don't set the TextView text to an empty string; instead, set it to null.
TextView myTextView = (TextView) findViewById(R.id.myTextView);
myTextView.setText(null);
