如何通过下一个片段
进行推送当前片段的动画这是我想要的动画:
我当前的动画代码只是将第一个片段与第二个片段重叠,它没有像图片中那样推送它
以下是代码:
result_list.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> av, final View view,
final int i, long i2) {
result_list.setEnabled(false);
view.animate().setDuration(300).translationX(widthListView).alpha(0).
withEndAction(new Runnable() {
@Override
public void run() {
//setResult(Activity.RESULT_OK,new Intent().putExtra("bussStopCode", data.get(i).getStopCode()).putExtra("bussStopName", data.get(i).getStopName()));
////int get 1
//data.remove(i);
int temporaryInteger = i;
listLastPostion = temporaryInteger;
//customAdapter.notifyDataSetChanged();
//view.setTranslationX(0);
Log.d("data",conreq.getCollectedData().getBusRouteSetData().get(temporaryInteger - 1).getRouteHeading());
Bundle bundle = new Bundle();
bundle.putString("busdestination", conreq.getCollectedData().getBusRouteSetData().get(temporaryInteger-1).getRouteHeading());
bundle.putString("busnumber", conreq.getCollectedData().getBusRouteSetData().get(temporaryInteger-1).getRouteNo());
Fragment fragment = new FragmentNextTripForStop();
fragment.setArguments(bundle);
FragmentTransaction fragmentManager = getFragmentManager().beginTransaction();
fragmentManager.setCustomAnimations(R.anim.right_left_anim_x_left,R.anim.right_left_anim_x_right,R.anim.left_right_anim_x_left,R.anim.left_right_anim_x_right);
fragmentManager.add(R.id.fragment_searched_data_xml, fragment).addToBackStack(null).commit();
// finish();
//overridePendingTransition(R.anim.right_left_anim_x_left,R.anim.right_left_anim_x_right);
}
});
}});

虽然这个问题是重复的,但是对于这个问题提供的答案对许多观众来说并不适用,并要求他们在结束时做出一些假设。
考虑到许多应用程序中存在此功能,这是一个很好的问题,但它需要非常复杂的答案。我将尝试将答案分解为一系列分隔步骤,以确保它是可重复的!
阻碍我们大多数人轻易这样做的问题是复合性质。要完全理解这个问题,让我列出问题:
FragmentManager
和FragmentTransaction
类提供了一种方便的方法,setCustomAnimations(int, int, int int)
,需要ObjectAnimators
ObjectAnimators
(传统方法)为了解决这个问题并提供所需的沉浸式体验,我们必须从多个角度解决这个问题。接下来的几个步骤将解释如何获取此功能!
我们首先需要为每个Fragment
定义一个自定义布局,因为我们必须具有对屏幕宽度的运行时访问权限,以及一个自包含的方法来操纵{{1}的x位置1}}(布局)基于此宽度。
View
现在,由于我们有一个特殊的布局,允许我们根据屏幕的物理宽度进行翻译,我们可以在相关的Fragment XML文件中使用它。
public class FractionTranslateLinearLayout extends LinearLayout{
private int screenWidth;
private float fractionX;
protected void onSizeChanged(int w, int h, int oldW, int oldh){
// Assign the actual screen width to our class variable.
screenWidth = w;
super.onSizeChanged(w, h, oldW, oldH);
}
public float getFractionX(){
return fractionX;
}
public void setFractionX(float xFraction){
this.fractionX = xFraction;
// When we modify the xFraction, we want to adjust the x translation
// accordingly. Here, the scale is that if xFraction is -1, then
// the layout is off screen to the left, if xFraction is 0, then the
// layout is exactly on the screen, and if xFraction is 1, then the
// layout is completely offscreen to the right.
setX((screenWidth > 0) ? (xFraction * screenWidth) : 0);
}
}
<com.[your_package_here].FractionTranslateLinearLayout
// Omitted namespace.
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/text_view_1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Fragment 1" />
</com.[your_package_here].FractionTranslateLinearLayout>
然后,我们必须创建包含实现转换的逻辑的<com.[your_package_here].FractionTranslateLinearLayout
// Omitted namespace.
android:id="@+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/text_view_2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Fragment 2" />
</com.[your_package_here].FractionTranslateLinearLayout>
类。
Fragment
public class Fragment1 extends Fragment {
public View onCreateView(LayoutInflater inf, ViewGroup vg, Bundle b){
// Simply inflate the View from the .xml file.
return inf.inflate(R.layout.fragment_1, vg, false);
}
}
现在让我们创建public class Fragment2 extends Fragment {
public View onCreateView(LayoutInflater inf, ViewGroup vg, Bundle b){
// Simply inflate the View from the .xml file.
return inf.inflate(R.layout.fragment_2, vg, false);
}
public void onActivityCreated (Bundle savedInstanceState){
View v = getView();
FractionTranslateLinearLayout layout;
layout = (FractionTranslateLinearLayout) v.findViewById(R.id.layout);
// Move the entire View off to the right of the screen for now.
layout.setFractionX(1.0f);
}
}
.xml文件,我们将用它们在屏幕上翻译objectAnimator
。请注意,我们需要其中的四个文件,因为每个进程需要一个(out和in),每个进程需要一个(左侧和右侧)。
View
<objectAnimator
// Omitted namespace.
android:valueFrom="0"
android:valueTo="-1"
// This String must be the exact name of the class variable.
android:propertyName="xFraction"
android:valueType="floatType"
// Duration in milliseconds.
android:duration="500"/>
<objectAnimator
// Omitted namespace.
android:valueFrom="0"
android:valueTo="1"
// This String must be the exact name of the class variable.
android:propertyName="xFraction"
android:valueType="floatType"
// Duration in milliseconds.
android:duration="500"/>
<objectAnimator
// Omitted namespace.
android:valueFrom="-1"
android:valueTo="0"
// This String must be the exact name of the class variable.
android:propertyName="xFraction"
android:valueType="floatType"
// Duration in milliseconds.
android:duration="500"/>
请注意,这些文件夹必须放在项目结构的“res / animator”目录中。
创建容器布局,当我们在它们之间转换时,它将容纳每个<objectAnimator
// Omitted namespace.
android:valueFrom="1"
android:valueTo="0"
// This String must be the exact name of the class variable.
android:propertyName="xFraction"
android:valueType="floatType"
// Duration in milliseconds.
android:duration="500"/>
。
Fragment
现在,我们必须创建将所有内容组合在一起的<com.android.FrameLayout
// Omitted namespace.
android:id="@+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
!
Activity
在此代码示例中,this class被大量使用。它的方法对于流程的执行至关重要!
请注意,我在这里做了一些假设,并且这段代码非常独特:
public class Main extends Activity {
private boolean showingFirstFragment;
public void onCreate(Bundle savedInstanceState){
setContentView(R.layout.main);
FragmentManager manager = getFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
// Keep track of which Fragment we are facing.
showingFirstFragment = true;
// Add the first Fragment to the container.
trans.add(R.id.main_container, new Fragment1(), "fragment_1");
trans.commit();
}
public void onBackPressed(){
// Override the back button functionality to simply switch
// Fragments. Note that this would normally be done in a click
// click listener.
switchFragments();
}
private void switchFragments(){
FragmentManager manager = getFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
// Set the animations that will emulate the functionality you
// requested.
int rightIn = R.animator.slide_right_in;
int rightOut = R.animator.slide_right_out;
int leftIn = R.animator.slide_left_in;
int leftOut = R.animator.slide_left_out;
// Note that we pass in 4 animations here. Please see the
// documentation on this method as it is critical to the
// understanding of this solution.
trans.setCustomAnimations(rightIn, leftOut, leftIn, rightOut);
if(showingFirstFragment){
int container = R.id.main_container;
// Show the second Fragment.
trans.replace(container, new Fragment2(), "fragment_2");
trans.commit();
showingFirstFragment = false;
}
else{
// Show the first Fragment by popping the back stack!
manager.popBackStack(null);
showingFirstFragment = true;
}
}
}
类,因此除非进行必要的修改,否则将无法使用支持包。Fragment
或更高版本。希望这里有足够的细节来回答你的问题。如果您需要,请告诉我。
此时,应该有足够的代码来实现您自己的解决方案。我在没有Eclipse编辑器的情况下输入了它,所以如果有任何错误,请提前接受我的道歉!
