问题
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.
Any ideas why this could be happening?
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.
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);
}
});
}
and here is my corresponding login.xml:

Thanks in advance!

So it seems that when you have the visibility set to INVISIBLE on the EditText fields it doesn't want to get focus.
I fixed this issue by changing the visibility on those fields after the animation completes like this:
animFadeIn.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationEnd(Animation animation) {
emailField.setVisibility(View.VISIBLE);
passwordField.setVisibility(View.VISIBLE);
logInText.setVisibility(View.VISIBLE);
loginButton.setVisibility(View.VISIBLE);
signupButton.setVisibility(View.VISIBLE);
}
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationRepeat(Animation animation) {}
});
Hope this helps you :)

It seems like you want to wait for the image (logo) to finish its animation then start the animations for TextView and EditView. Instead of using setAnimationListener what you can do is set the start offset value of animFadeIn to 4000 miliseconds.
Try this:
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 animFadeIn = AnimationUtils.loadAnimation(getApplicationContext(), android.R.anim.fade_in);
animFadeIn.setDuration(2000);
animFadeIn.setStartOffset(4000);
animFadeIn.setFillAfter(true);
emailField.setAnimation(animFadeIn);
passwordField.setAnimation(animFadeIn);
logInText.setAnimation(animFadeIn);
loginButton.setAnimation(animFadeIn);
signupButton.setAnimation(animFadeIn);
The keyboard opens up fine for me.

Had the same problem. Just don't use fillAfter, it's crap. Combine with @Wextux's solution.
