Android的 - 键盘不会出现的EditText动画后会发生

我在这里看到的问题/解决方案的键盘显示不出来，但没有关于我的具体问题。当你点击一个EditText，键盘显示了罚款。但是，当我第一次动画的EditText，那么当你点击的EditText键盘不会出现。

I have seen questions/solutions here for the keyboard not showing up, but none relating to my specific issue. When you click an EditText, the keyboard shows up fine. But, when I animate the EditText first, then when you click the EditText the keyboard will NOT show up.

任何想法，为什么这可能发生？

Any ideas why this could be happening?

在我的活动我第一次动画我的标志，它完成动画后，我创建了一个淡入动画的EditTexts。他们完成了动画之后，我尝试点击其中的任何但键盘不会出现。

In my Activity I first animate my logo, and after it's done animating I create a fade-in animation for the EditTexts. After they finish the animation, I try and click any of them but the keyboard will not show up.

下面是我的onCreate方法在我的活动：

Here is my onCreate method in my Activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); //Remove title bar

    setContentView(R.layout.login);

    final EditText emailField = (EditText) findViewById(R.id.emailField);
    final EditText passwordField = (EditText) findViewById(R.id.passwordField);
    final TextView logInText = (TextView) findViewById(R.id.logInText);
    final Button signupButton = (Button) findViewById(R.id.signupButton);
    final Button loginButton = (Button) findViewById(R.id.loginButton);

    //animation of logo
    ImageView img_animation = (ImageView) findViewById(R.id.encoreLogo);

    TranslateAnimation animation = new TranslateAnimation(0.0f, 00f,
            0.0f, -400.0f);  
    animation.setDuration(4000);  
    animation.setFillAfter(true);   
    animation.setStartOffset(2000);

    img_animation.startAnimation(animation); 

    animation.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationEnd(Animation animation) {
            Animation animFadeIn = AnimationUtils.loadAnimation(getApplicationContext(), android.R.anim.fade_in);
            animFadeIn.setDuration(2000);
            animFadeIn.setFillAfter(true);

            emailField.setAnimation(animFadeIn);
            passwordField.setAnimation(animFadeIn);
            logInText.setAnimation(animFadeIn);
            loginButton.setAnimation(animFadeIn);
            signupButton.setAnimation(animFadeIn);


        }
        @Override
        public void onAnimationRepeat(Animation animation) {}
        @Override
        public void onAnimationStart(Animation animation) {}

    });

    signupButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent(MainActivity.this, SignUpActivity.class);
            MainActivity.this.startActivity(myIntent);

        }
    });


}
