Question

On my Android App there is a EditText which is supposed to keep numeric values; that’s why I defined it as

    <EditText android:layout_width="fill_parent" android:id="@+id/TextNumb" 
android:layout_height="wrap_content" android:gravity="right|center" android:maxLines="1"
 android:maxLength="10" android:inputType="number|numberSigned|numberDecimal"/>

But at a certain point of my App I want to clear it, so in my Activity I call this EditText View and I write:

mEditView.setText("");

But I get a run-time error…how could I fix it? Is there a way to clean it?

Answer 1

You shan’t get runtime error calling mEditView.setText("");. If you do, then you do something wrong outside this expression, and we need your code to tell what specifically. My guess would be not initialized mEditView (NullPointerException) or calling setText on different thread than UI (java.lang.RuntimeException).
