Android TranlateAnimation背景不起作用

Question

I am usig TranlateAnimation to showing and hiding EditText. First EditText has visibility gone. After it takes visibility visible and tranlating up. When EditText get focus backgroung of all app becomes black. When focus of EditText is lost everything becomes good. Maybe it's because I use ViewPager which contains all fragrament. What is the problem of this? Here is code of animation:

private void initAnimationDown() {
    animationDown = new TranslateAnimation(0, 0, 0, height);
    animationDown.setFillAfter(true);
    animationDown.setDuration(500);
    }
private void initAnimationUp() {
    animationUp = new TranslateAnimation(0, 0, height, 0);
    animationUp.setFillAfter(true);
    animationUp.setDuration(500);
    }

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

    if (isChecked) {
        initAnimationUp();
        perfectEditText.startAnimation(animationUp);
        perfectEditText.setVisibility(View.VISIBLE);

    } else {
        initAnimationDown();
        perfectEditText.startAnimation(animationDown);
        perfectEditText.setVisibility(View.GONE);
    }
}

What if you try to unvalidate the edit text before hidding him and starting animation?

perfectEditText.setFocusable( false );
perfectEditText.setFocusableInTouchMode( false );
