OnClickListener直到onResume()才会触发

我有一个活动,其中几个视图动画。单击包含少量图像的RelativeLayout时会触发动画。它在onCreate()中设置如下:

mContainer.setOnClickListener(new ContainerClicked());

而且ContainerClicked()类看起来像这样:

private class ContainerClicked implements OnClickListener {

    @Override
    public void onClick(View arg0) {
        Log.i(TAG, "TEST!");
        mSomeButton.setOnClickListener(null);
        mSomeButton.setEnabled(false);

        mAnotherButton.setOnClickListener(null);
        mAnotherButton.setEnabled(false);

        mYetAnotherButton.setOnClickListener(null);
        mYetAnotherButton.setEnabled(false);

        mContainer.setOnClickListener(null);
        if (mLogo.getVisibility() == View.VISIBLE)
            new AnimateToParty().execute();
        else
            new AnimateFromParty().execute();
    }
}

这样可行,并根据我的需要设置动画。

AnimateToParty()如下所示:

private class AnimateToParty extends AsyncTask<Void, Integer, Void> {

    @Override
    protected void onProgressUpdate(final Integer... values) {
        final View theView = findViewById(values[0]);
        if (!(values[0] == mBackgroundImage.getId() || values[0] == mContainer
                .getId())) {
            final Animation animation = AnimationUtils.loadAnimation(
                    DashboardActivity.this, values[1]);
            animation.setAnimationListener(new AnimationListener() {

                @Override
                public void onAnimationStart(Animation arg0) {
                }

                @Override
                public void onAnimationRepeat(Animation arg0) {
                }

                @Override
                public void onAnimationEnd(Animation arg0) {
                    theView.setVisibility(View.INVISIBLE);
                }
            });
            theView.startAnimation(animation);
        } else if (values[0] == mBackgroundImage.getId()) {
            TransitionDrawable transition = (TransitionDrawable) theView
                    .getBackground();
            transition.startTransition(getResources().getInteger(
                    android.R.integer.config_mediumAnimTime));
        } else {
            TranslateAnimation animation = new TranslateAnimation(0, 0, 0,
                    TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
                            -60, getResources().getDisplayMetrics()));
            animation.setAnimationListener(new AnimationListener() {

                @Override
                public void onAnimationStart(Animation arg0) {
                }

                @Override
                public void onAnimationRepeat(Animation arg0) {
                }

                @Override
                public void onAnimationEnd(Animation arg0) {
                    LayoutParams lp = (LayoutParams) mContainer
                            .getLayoutParams();
                    lp.bottomMargin = 0;
                    RelativeLayout parent = (RelativeLayout) mContainer
                            .getParent();
                    mSomeButton.setVisibility(View.GONE);
                    mAnotherButton.setVisibility(View.GONE);
                    mYetAnotherButton.setVisibility(View.GONE);
                    mLogo.setVisibility(View.GONE);
                    // mContainer.setLayoutParams(lp);
                    // This caused a visible flicker, so I went with the solution below.
                    parent.removeView(mContainer);
                    parent.addView(mContainer, lp);
                }
            });
            animation.setDuration(1000);
            mContainer.startAnimation(animation);
        }
    }

    @Override
    protected Void doInBackground(Void... arg0) {
        try {
            publishProgress(mContainer.getId());
            publishProgress(mLogo.getId(), R.anim.slide_out_up);
            Thread.sleep(100);
            publishProgress(mSomeButton.getId(), R.anim.slide_out_left);
            Thread.sleep(110);
            publishProgress(mAnotherButton.getId(), R.anim.slide_out_left);
            Thread.sleep(120);
            publishProgress(mYetAnotherButton.getId(), R.anim.slide_out_left);
            Thread.sleep(130);
            publishProgress(mBackgroundImage.getId());
            Thread.sleep(550);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        mContainer.setOnClickListener(new LighterClicked());
    }
}

上面的类动画了一些按钮和徽标,然后显示容器。为了保持它,我改变了它的布局框架。只是更改它们会产生一个可见的闪烁,其中容器跳跃60向上倾斜大约一帧(动画似乎没有完全完成),然后在我想要的地方定居。我读到某个地方将其从父母中移除并将其重新放入,这不会产生相同的闪烁。但是,现在重新绑定onclicklistener不起作用!

我已经尝试了所有的东西,我现在注意到,如果我按下主页按钮并再次打开应用程序,那么没有“通过”的每次点击都会触发。

有没有更好的方法来避免“闪烁”?做动画的更好方法是什么? (我对动画视图很新)为什么重新打开应用程序时点击事件会激活?

为避免您看到的闪烁,您必须在 onAnimationEnd

的开头调用 clearAnimation()
@Override
public void onAnimationEnd(Animation arg0) {
    theView.clearAnimation()
    ...
}
