我刚开始使用HoneyComb的片段设计。我创建了两个片段。当我点击按钮'santhosh'(在图片的左侧)时,在另一个片段(图片的右侧)中创建一个按钮。接下来我想为下一个按钮创建监听器,以便在同一个片段中创建下一个活动(即右侧片段中的新活动)。我的代码如下。 main.xml中
<?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="horizontal" >
<fragment class="com.fragment.example.Titles"
android:id="@+id/titles" android:layout_weight="1"
android:layout_width="0px"
android:layout_height="match_parent" />
<FrameLayout android:id="@+id/details" android:layout_weight="1"
android:layout_width="0px"
android:layout_height="match_parent" />
</LinearLayout>
FragmentExample.java
public class FragmentExample extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
Titles.java
public class Titles extends Fragment {
public FragmentTransaction ft;
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.main1, null);
Button button1 = (Button)v.findViewById(R.id.button1);
button1.setText("santhosh");
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
DetailsFragment details = (DetailsFragment)
getFragmentManager().findFragmentById(R.id.details);
if (details == null || details.getShownIndex() != 1) {
// Make new fragment to show this selection.
details = DetailsFragment.newInstance(1);
// Execute a transaction, replacing any existing
// fragment with this one inside the frame.
ft
= getFragmentManager().beginTransaction();
ft.add(R.id.details, details, "detail");
ft.setTransition(
FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
}
}
});
return v;
}
}
DetailsFragment.java
public class DetailsFragment extends Fragment {
/**
* Create a new instance of DetailsFragment, initialized to
* show the text at 'index'.
*/
Titles title = new Titles();
String[] titles = {"Title1", "Title2", "Title3", "Title4"};
public static DetailsFragment newInstance(int index) {
DetailsFragment f = new DetailsFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
f.setArguments(args);
return f;
}
public int getShownIndex() {
return getArguments().getInt("index", 0);
}
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
if (container == null) {
// Currently in a layout without a container, so no
// reason to create our view.
return null;
}
Button button = new Button(getActivity());
button.setText("Next");
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
return button;
}
}
在DetailsFragment.java中,我想显示一个带有该片段的新活动。
答案 0 :(得分:6)
接下来我想为下一个按钮创建监听器,以便在同一个片段中创建下一个活动(即右侧片段中的新活动)。
对不起,这不受支持。不推荐使用嵌套活动。
