动画我的FragmentTabHost

Question

我尝试实现FragmentTabHost它可以工作但我想点击标签时动画。

以下是我的标签主持人的片段：

    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
        @Override
        public void onTabChanged(String tabId) {
            View currentView = mTabHost.getCurrentView();

            if (mTabHost.getCurrentTab() > currentTab) {
                currentView.setAnimation(inFromRightAnimation());
            } else {
                currentView.setAnimation(outToRightAnimation());
            }

            currentTab = mTabHost.getCurrentTab();
        }
    });

    mTabHost.setup(this, getSupportFragmentManager(), android.R.id.tabcontent);

    mTabHost.addTab(
            mTabHost.newTabSpec("Tab 1").setIndicator("Tab 1", null),
            PostSoovyFragment.class, null);
    mTabHost.addTab(
            mTabHost.newTabSpec("Tab 2").setIndicator("Tab 2", null),
            SooviesFragment.class, null);
    mTabHost.addTab(
            mTabHost.newTabSpec("Tab 3").setIndicator("Tab 3", null),
            SettingsFragment.class, null);

这些是我正在使用的动画：

private Animation inFromRightAnimation() {
    Animation inFromRight = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, +1.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f);
    inFromRight.setDuration(240);
    inFromRight.setInterpolator(new AccelerateInterpolator());
    return inFromRight;
}

private Animation outToRightAnimation() {
    Animation outtoLeft = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, -1.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f);
    outtoLeft.setDuration(240);
    outtoLeft.setInterpolator(new AccelerateInterpolator());
    return outtoLeft;
}

可悲的是，当我在4.4.4手机上测试时。标签之间没有动画。
