How I can clear the value of TextView?
题
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?
解决方案
TextView myTextView = (TextView) findViewById(R.id.myTextView);
myTextView.setText("");
其他提示
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);
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()
