(Android) TextView Animation 처리 fade in/out

    final TextView mSwitcher = (TextView) findViewById(R.id.bookContent); mSwitcher.setText("old text");

    final Animation in = new AlphaAnimation(0.0f, 1.0f);
    in.setDuration(3000);

    final Animation out = new AlphaAnimation(1.0f, 0.0f);
    out.setDuration(3000);

    Button moveOn = (Button) findViewById(R.id.moveOn);
    moveOn.setOnClickListener( new OnClickListener() {
        public void onClick(View v) {

            mSwitcher.startAnimation(out);
            mSwitcher.setText("new text");
            mSwitcher.startAnimation(in);

        }
    });

 

 

 

==> 수정

 

out.setAnimationListener(new AnimationListener() {

    @Override
    public void onAnimationEnd(Animation animation) {
        mSwitcher.setText("New Text");
        mSwitcher.startAnimation(in);

    }
});

Then, in your onClick() method:

public void onClick(View v) {

    mSwitcher.startAnimation(out);

}
