当输入框为空提交时，输入框抖动提醒，看效果:(录屏原因效果不好，实际效果更好些)

if (TextUtils.isEmpty(mEt.getText().toString().trim())) {
    // 抖动动画
    Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
    // 动画插值器
    CycleInterpolator interpolator = new CycleInterpolator(7);
    shake.setInterpolator(interpolator);
    //EditText 设置动画
    mEt.startAnimation(shake);
}

动画文件在res->anim->shake
