Question

In my application in android are many EditText fields. And I ran into a problem with hint. It is not disappearing when EditText is focused, but it disappears when I start to

The proposed selector solution by windyzboy doesn't work for EditTexts with centered text, because the cursor stays behind the transparent hint text instead of moving to the center.

A good way without polluting your code is to make a custom EditText, since you probably need the same style in the whole application. That way you can avoid adding checks for each EditText separately.

public class HideHintEditText extends EditText {

    CharSequence hint;

    public HideHintEditText(Context context) {
        super(context);
        hint = this.getHint();
    }

    public HideHintEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        hint = this.getHint();
    }

    public HideHintEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        hint = this.getHint();
    }

    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect);

        this.setHint(focused ? "" : hint);
    }

}
