Android - Sliding Fragments
android, animation, fragment, sliding
Solution
I guess what you are trying to implement can very easily be implemented by a ViewPager
ViewPager is a custom component that was introduced to implement easy and smooth switching between fragments . Android Documentation has a very good and easy to understand example to understand it's use Take a look at http://developer.android.com/training/animation/screen-slide.html .You can also see similar questions that have been answered Example/Tutorial for ViewPager and Fragments and How to use Android ViewPager?
Problem
I'm trying to implement the sliding animation to transit from fragment1 to fragment2. I'm using setCustomAnimations method. And I understand I need to use the frame method in order to replace fragments. My code: ``` package com.example.fragmentss; import android.os.Bundle; import android.app.Activity; import android.view.Menu; public class MainActivity extends Activity implements MyListFragment.OnItemSelectedListener{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragment_rsslist_overview); } // if the wizard generated an onCreateOptionsMenu you can delete // it, not needed for this tutorial @Override public void onRssItemSelected(String link) { } } ``` activity_main.xml ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" > <fragment android:id="@+id/listFragment" android:layout_width="0dp" android:layout_weight="1" android:layout_height="match_parent" class="com.example.fragmentss.MyListFragment" ></fragment> <FrameLayout android:id="@+id/details" android:layout_weight="1" android:layout_width="0px" android:layout_height="match_parent" android:background="?android:attr/detailsElementBackground" /> </LinearLayout> ``` MyListFragment class ``` package com.example.fragmentss; import android.app.Activity; import android.app.Fragment; import android.app.FragmentTransaction; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; public class MyListFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_rsslist_overview, container, false); return view; } public void onClick2(View view) { switch (view.getId()) { case R.id.button2: FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right); DetailFragment newFragment = DetailFragment.newInstance(); ft.replace(R.id.details, newFragment, "mylistFragment"); // Start the animated transition. ft.commit(); break; } } } ~ ``` fragment_rssitem_detail.xml ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Goto 2" android:onClick="onClick1"/> <TextView android:id="@+id/detailsText" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="center_horizontal|center_vertical" android:layout_marginTop="20dip" android:text="Frag 1" android:textAppearance="?android:attr/textAppearanceLarge" android:textSize="30dip" /> </LinearLayout> ``` fragment_rsslist_overview.xml ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Goto 1" android:onClick="onClick2" /> <TextView android:id="@+id/textView1" android:layout_width="256dp" android:layout_height="wrap_content" android:layout_weight="0.18" android:text="Frag 2" android:textSize="30dip"/> </LinearLayout> ```
