带有 Activity 的 Android fragment

Question

我刚刚开始为 HoneyComb 设计 fragment 。我创建了两个 fragment 。当我单击“santhosh”按钮(图片左侧)时，将在另一个 fragment (图片右侧)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 fragment 中创建下一个 Activity (即右侧 fragment 中的新 Activity )。我的代码如下。主.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="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>

fragment 示例.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);


}
 }

标题.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;
}
}

我想从 DetailsFragment.java 中显示带有该 fragment 的新 Activity。

Answer 1

Next I want to make listener for next button, so that next activity is created in the same fragment(ie. new activity within the right side fragment).

不支持，抱歉。嵌套 Activity 已弃用。
