Display a message inside Android Edit Text Field

问题

Hai, I have an Android Program with one text field. I need to display a message inside that textfield when it loads on an emulator. When the user clicks inside that textbox that message should dispappear. For Ex: Please enter name Can any one post some sample code over here...

回答1:

Just use or call setHint on the object. Hint text to display when the text is empty.

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="18px"
        android:gravity="left"
        android:hint="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse egestas ullamcorper facilisis." />

You need to use the attribute Hint of the EditText.

android:hint in your xml
setHint(int) at runtime

This will execute just what you need
