Blinking Android view

A blinking view can attract user’s attention.

If we want some view like button or textView blink, we have two ways to do.

Assume that it’s a textView, in xml file, you add some lines of code.

<blink

     android:layout_width="wrap_content"

     android:layout_height="wrap_content" >

    <TextView

        android:id="@+id/tv"

        android:layout_width="200dp"

        android:layout_height="50dp"

         android:layout_marginTop="15dp"

        android:layout_gravity="center_horizontal"

        android:text="TextView blinking"

        android:textColor="#800000"      

        android:textSize="20dp" />

   </blink>

Second way we do in code, below findViewByid, add these lines.

Animation mAnimation = new AlphaAnimation(1, 0);

mAnimation.setDuration(200);

mAnimation.setRepeatCount(Animation.INFINITE);

mAnimation.setRepeatMode(Animation.REVERSE); tv.startAnimation(mAnimation);

To make it blink faster, change value of line

mAnimation.setDuration(200); to smaller value.
