Android-动画发生后,键盘不会显示edittext

作者:互联网

我在这里看到了有关键盘未出现的问题/解决方案,但与我的特定问题无关.当您单击一个EditText时,键盘显示正常.但是,当我先为EditText设置动画时,然后当您单击EditText时,键盘将不会显示.

任何想法为什么会发生这种情况?

在“活动”中,我首先为徽标设置动画,然后完成动画设置,然后为EditTexts创建淡入动画.他们完成动画后,我尝试单击它们中的任何一个,但键盘不会出现.

这是我的Activity中的onCreate方法:

@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);

        }
    });


}

这是我对应的login.xml:

提前致谢!

解决方法:

如此看来,当您在EditText字段上将可见性设置为INVISIBLE时,它并不想获得焦点.

我通过在动画完成后更改这些字段的可见性来解决此问题:

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) {}

});

希望这对您有所帮助:)
