我在处理onAnimationEnd时遇到了麻烦，让我解释一下：TopBar是包含所有片段的主要活动所以我试图在其他类中放入一些代码并在需要时调用TopBar，它可以工作，当我点击配置文件按钮上的SlideLeftIn（视图，上下文）工作很好，但如果我单击后退按钮然后动画无法启动，主页（第0页）立即开始，所以，试图等待动画结束，我我在MyAnim中创建了另一个方法，我在OnAnimationEnd中插入了setPage（），所以我有了SlideLeftOut（视图，上下文，页面），然后我得到了非常的例句，我搜索了解决方案但是找不到答案我的情况，这是我的主要活动TopBar：
public class TopBar extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.top_bar);
if( savedInstanceState == null ) {
setPage();
}
//many button.onclicklistener for choose the page for fragment
}
@Override
public void onBackPressed() {
if (main==0) {
if (profl==1) {
profl=0;
myanim.SlideLeftOut(profview,TopBar.this,0);
} else {
setPage();
}
} else {
finish();
}
}
public void setPage() {
setPage(0);
}
public void setPage(int pg) {
Frammento fg = new Frammento();
Bundle args = new Bundle();
args.putInt("PAGINA_FRAGMENT", pg);
fg.setArguments(args);
FragmentManager fragmentManager = getSupportFragmentManager();
if (pg==1) {
fragmentManager.beginTransaction().replace(R.id.searchbar, fg).commit();
} else {
fragmentManager.beginTransaction().replace(R.id.pageFragment, fg).commit();
}
}
public class Frammento extends Fragment {
public Frammento() {}
@Override
public View onCreateView(LayoutInflater inf,ViewGroup contenitore,Bundle savedInstanceState ){
View radice;
int pag = getArguments().getInt("PAGINA_FRAGMENT");
switch(pag) {
case 0:
radice = inf.inflate(R.layout.logged,contenitore,false);
break;
case 1:
radice = inf.inflate(R.layout.srcbarlayout,contenitore,false);
break;
case 2:
radice = inf.inflate(R.layout.insertnew,contenitore,false);
break;
case 3:
radice = inf.inflate(R.layout.searchevent,contenitore,false);
break;
case 4:
radice = inf.inflate(R.layout.myprofile,contenitore,false);
break;
case 5:
radice = inf.inflate(R.layout.message,contenitore,false);
break;
case 6:
radice = inf.inflate(R.layout.invitation,contenitore,false);
break;
case 7:
radice = inf.inflate(R.layout.mostraevento,contenitore,false);
break;
default:
radice = inf.inflate(R.layout.logged,contenitore,false);
break;
}
pageManager(pag,radice);
return radice;
}
}
pageManager（pag，radice）只是对选择的布局进行操作，这是MyAnim.java：
public class MyAnim {
public void SlideLeftIn(final View view, Context c){
Animation animation = AnimationUtils.loadAnimation(c, R.anim.left_slide_in);
animation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationRepeat(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {}
});
view.startAnimation(animation);
}
public void SlideLeftOut(final View view,final Context c,final int i){
Animation animation = AnimationUtils.loadAnimation(c, R.anim.left_slide_out);
animation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationRepeat(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {
view.setVisibility(View.GONE);
TopBar main = new TopBar();
main.setPage(i);
}
});
}
}
xml：
