android - 更改选项卡时添加动画

Question

你好我有一个包含两个子 Activity 的 TabHost Activity 。为子 Activity 添加“左 - 右”动画的最佳解决方案是什么？

最好的问候!

Answer 1

你好
最好的解决方案是在布局中添加动画
假设你有两个标签

tabs = (TabHost) this.findViewById(R.id.tabhost_id);
        tabs.setup();    
        tspec1 = tabs.newTabSpec(name_of_1st_tab)
        tspec1.setIndicator(....);
        tspec1.setContent(R.id.tab_1_layout_id);
  tab1Layout = (LinearLayout)findViewById(R.id.tab_1_layout_id);

   tspec2 = tabs.newTabSpec(name_of_2nd_tab)
        tspec2.setIndicator(....);
        tspec2.setContent(R.id.tab_1_layout_id);
  tab1Layout = (LinearLayout)findViewByIdR.id.tab_2_layout_id);

然后在 TabChangedListener 上

    tabs.setOnTabChangedListener(new OnTabChangeListener() {

        public void onTabChanged(String tabId) {
  tab1Layout.setAnimation(outToLeftAnimation());
  tab2Layout.setAnimation(inFromRightAnimation());
             }
      });

   public 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(ConstandsUsed.ANIMATIION_DURATION);
    inFromRight.setInterpolator(new AccelerateInterpolator());
    return inFromRight;
}

public Animation outToLeftAnimation() {
    Animation outtoLeft = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, -1.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f);
    outtoLeft.setDuration(ConstandsUsed.ANIMATIION_DURATION);
    outtoLeft.setInterpolator(new AccelerateInterpolator());
    return outtoLeft;
}

希望这对你有所帮助
