我正在尝试实现从fragment1 到fragment2 的滑动动画。我正在使用 setCustomAnimations 方法。而且我知道我需要使用框架方法来替换片段。
我的代码：
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 类
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;
}
}
} ~
