如何替換片段運行時間

我想添加和替換框架佈局與片段1和片段2上的項目單擊網格和列表項目。如何替換片段運行時間

我所創造的main.xml類

<?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" > 

<LinearLayout 
    android:layout_width="0dp" 
    android:layout_weight="1" 
    android:orientation="vertical" 
    android:layout_height="fill_parent" > 

    <fragment 
     android:id="@+id/fragment1" 
     android:layout_width="match_parent" 
     android:layout_height="0dp" 
     android:layout_weight="1" 
     class="com.example.fragment.Fragment1" /> 

    <View 
     android:layout_width="fill_parent" 
     android:layout_height="1dp" 
     android:background="#000000" /> 

    <fragment 
     android:id="@+id/fragment2" 
     android:layout_width="match_parent" 
     android:layout_height="0dp" 
     android:layout_weight="1" 
     class="com.example.fragment.Fragment2" /> 
</LinearLayout> 

<View 
    android:layout_width="1dp" 
    android:layout_height="fill_parent" 
    android:background="#000000" /> 

<FrameLayout 
    android:id="@+id/fragment3" 
    android:layout_width="0dp" 
    android:layout_height="fill_parent" 
    android:layout_weight="2"/>

這裏是我的fragment_1.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" 
android:paddingLeft="8dp" 
android:paddingRight="8dp" > 

<GridView 
    android:id="@+id/Grid1" 
    android:layout_width="match_parent" 
    android:numColumns="auto_fit" 
    android:columnWidth="100dp" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:drawSelectorOnTop="false" />

，這裏是我的row_fragment1_list.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:layout_margin="15dp" 
android:orientation="vertical" > 

<ImageView 
    android:id="@+id/img_view" 
    android:layout_width="50dp" 
    android:layout_height="50dp" 
    android:background="#CCCCCC" 
    android:textSize="16sp" 
    android:textStyle="bold" /> 

<TextView 
    android:id="@+id/text2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:textSize="16sp" />

和fragment_3.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:gravity="center" 
android:orientation="vertical" > 

<TextView 
    android:id="@+id/tv_fragment3" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textSize="22sp" 
    android:gravity="center" 
    android:text="This is 3rd Fragment" />

這裏是我的main.xml

public class Main extends Activity 
{ 
    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
    } 
}

，這裏是Fragment1.class

public class Fragment1 extends Fragment implements OnItemClickListener 
{ 
    Activity myActivity; 
    GridView mGridView; 
    private String ListItem[] = {"Item 1","Item 2","Item 3","Item 4","Item 5","Item 6","Item 7"}; 
    private int imgID[] = {R.drawable.admin_access_rule, 
      R.drawable.admin_backup,R.drawable.admin_browsesite, 
      R.drawable.admin_comment_post,R.drawable.admin_content, 
      R.drawable.admin_content_type,R.drawable.admin_logout,}; 

    @Override 
    public void onAttach(Activity activity) 
    { 
     super.onAttach(activity); 
     this.myActivity = activity; 
     Toast.makeText(activity.getApplicationContext(), "On Attach", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     Toast.makeText(myActivity.getApplicationContext(), "On Create", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    { 
     Toast.makeText(myActivity.getApplicationContext(), "On Create View", Toast.LENGTH_SHORT).show(); 

     View view = inflater.inflate(R.layout.fragment_1,container, false); 
     mGridView = (GridView)view.findViewById(R.id.Grid1); 

     return view; 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) 
    { 
     Toast.makeText(myActivity.getApplicationContext(), "On Activity Created", Toast.LENGTH_SHORT).show(); 
     super.onActivityCreated(savedInstanceState); 
    } 

    @Override 
    public void onStart() 
    { 
     super.onStart(); 
     mGridView.setAdapter(new GridBaseAdapter(myActivity)); 
     mGridView.setOnItemClickListener(this); 
    } 

    private class GridBaseAdapter extends BaseAdapter 
    { 
     LayoutInflater mLayoutInflater = null; 
     public GridBaseAdapter(Context mContext) 
     { 
      mContext = myActivity; 
      mLayoutInflater = LayoutInflater.from(mContext); 
     } 

     @Override 
     public int getCount() 
    { 
     return ListItem.length; 
    } 

    @Override 
    public Object getItem(int position) 
    { 
     return null; 
    } 

    @Override 
    public long getItemId(int position) 
    { 
     return ListItem.length; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) 
    { 

     if(convertView == null) 
     { 
      convertView = mLayoutInflater.inflate(R.layout.row_fragment_list, null); 
     } 

     ImageView mImageView = (ImageView) convertView.findViewById(R.id.img_view); 
     mImageView.setImageResource(imgID[position]); 

     TextView tvUserEmail = (TextView) convertView.findViewById(R.id.text2); 
     tvUserEmail.setText("Sub " +ListItem[position]);    

     return convertView; 
    } 
} 

@Override 
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) 
{ 
    TextView txt3 = (TextView)myActivity.findViewById(R.id.tv_fragment3); 
    txt3.setText("1st Fragment's : " + position +" Item Clicked"); 
} 
}

我Fragment2.class

public class Fragment2 extends ListFragment 
{ 
    Activity myActivity; 
    private String ListItem[] = {"Item 1","Item 2","Item 3","Item 4","Item 5","Item 6","Item 6","Item 7"}; 

@Override 
public void onAttach(Activity activity) 
{ 
    super.onAttach(activity); 
    this.myActivity = activity; 
    Toast.makeText(activity.getApplicationContext(), "On Attach", Toast.LENGTH_SHORT).show(); 
} 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    Toast.makeText(myActivity.getApplicationContext(), "On Create", Toast.LENGTH_SHORT).show(); 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
    Toast.makeText(myActivity.getApplicationContext(), "On Create View", Toast.LENGTH_SHORT).show(); 

    /** Creating an array adapter to store the list of countries **/ 
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(inflater.getContext(), android.R.layout.simple_list_item_1,ListItem); 
    /** Setting the list adapter for the ListFragment */ 
    setListAdapter(adapter); 

    return super.onCreateView(inflater, container, savedInstanceState); 
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) 
{ 
    Toast.makeText(myActivity.getApplicationContext(), "On Activity Created", Toast.LENGTH_SHORT).show(); 
    super.onActivityCreated(savedInstanceState); 
} 

@Override 
public void onListItemClick(ListView l, View v, int position, long id) 
{ 
    Toast.makeText(myActivity.getApplicationContext(), position +" Item Clicked", Toast.LENGTH_SHORT).show(); 
    TextView txt3 = (TextView)myActivity.findViewById(R.id.tv_fragment3); 
    txt3.setText("2nd Fragment's : " + position +" Item Clicked"); 
    super.onListItemClick(l, v, position, id); 
} 
}

和最後我Fragment3.class

public class Fragment3 extends Fragment 
{ 
Activity myActivity; 
TextView txt_view; 
@Override 
public void onAttach(Activity activity) 
{ 
    super.onAttach(activity); 
    this.myActivity = activity; 
    Toast.makeText(activity.getApplicationContext(), "On Attach", Toast.LENGTH_SHORT).show(); 
} 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    Toast.makeText(myActivity.getApplicationContext(), "On Create", Toast.LENGTH_SHORT).show(); 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{ 
    Toast.makeText(myActivity.getApplicationContext(), "On Create View", Toast.LENGTH_SHORT).show(); 
    View view = inflater.inflate(R.layout.fragment_3,container, false); 
    txt_view = (TextView)view.findViewById(R.id.tv_fragment3); 
    return view; 
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) 
{ 
    Toast.makeText(myActivity.getApplicationContext(), "On Activity Created", Toast.LENGTH_SHORT).show(); 
    super.onActivityCreated(savedInstanceState); 
} 
}

你期待別人去通過所有的代碼，當你還沒有什麼問題中去錯說？ – 2013-02-14 10:58:09

如果你不鼓勵新來者，不要阻止我們。 – 2013-02-14 11:06:21

我無法相信你如何能在此獲得2 upvotes。我的評論只是因爲如果你對你的問題做了一些研究，問題可能會更加清楚。 – 2013-02-14 12:54:14

使碎片暴露的界面，你的活動可以附加本身。該事件應在需要時發生（例如，列表項被點擊）。然後，活動應該把片段的實例，它應該是，例如：

// fragment is an instance of the fragment you want to show 
final FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); 
transaction.replace(R.id.fragment3, fragment); 
transaction.commit();
