我想在另一個片段內單擊一個對話框時打開一個片段。我在Tab中使用了ActionBarSherlock。我的片段附加在視圖尋呼機中。我幾乎完成了這項工作。但我不能在視圖尋呼機中替換一個新的片段。我有一個錯誤。我讀了線程here。解決方案尚不清楚。當單擊對話框時將另一個片段替換爲另一個片段(viewpager)
錯誤:
10-18 21:34:40.379: E/AndroidRuntime(19618): FATAL EXCEPTION: main 10-18 21:34:40.379: E/AndroidRuntime(19618): java.lang.IllegalArgumentException: No view found for id 0x7f040032 (com.example.actionbartestwithsherlock:id/pager) for fragment AllContactsFragment{41fd4ba0 #0 id=0x7f040032} 10-18 21:34:40.379: E/AndroidRuntime(19618): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:903)
我有尋呼機命名FragmentTab1,FragmentTab2 & FragmentTab3 3組片段的同事。
我MainActivity & FragmentAdapter看起來象下面這樣:
public class MainActivity extends SherlockFragmentActivity {
ActionBar.Tab Tab1, Tab2, Tab3, Tab4;
private Context context = this;
// view pager
// Declare Variables
ActionBar actionBar;
ViewPager mPager;
Tab tab;
FragmentAdapter mAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// set application in portrait mode
ActivityHelper.initialize(this);
actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Locate ViewPager in activity_main.xml
mPager = (ViewPager) findViewById(R.id.pager);
// add an adapter to pager
mPager.setAdapter(new FragmentAdapter(getSupportFragmentManager(),
mPager, actionBar));
addActionBarTabs();
}
private void addActionBarTabs() {
String[] tabs = { "Tab 1", "Tab 2", "Tab 3" };
for (String tabTitle : tabs) {
ActionBar.Tab tab = actionBar.newTab().setText(tabTitle)
.setTabListener(tabListener);
actionBar.addTab(tab);
}
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
}
private ActionBar.TabListener tabListener = new ActionBar.TabListener() {
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
mPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
}
};
class FragmentAdapter extends FragmentPagerAdapter implements
ViewPager.OnPageChangeListener {
private ViewPager mViewPager;
final int TOTAL_PAGES = 3;
public FragmentAdapter(FragmentManager fm, ViewPager pager,
ActionBar actionBar) {
super(fm);
this.mViewPager = pager;
this.mViewPager.setOnPageChangeListener(this);
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return FragmentTab1.newInstance();
case 1:
return FragmentTab2.newInstance();
case 2:
return FragmentTab3.newInstance();
default:
throw new IllegalArgumentException(
"The item position should be less or equal to:"
+ TOTAL_PAGES);
}
}
@Override
public int getCount() {
return TOTAL_PAGES;
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
}
}
現在,在我的第一個標籤FragmentTab1,我打開一個自定義對話框時,點擊一個按鈕。當選擇對話框選項時,我想在FragmentTab1中替換新的片段AllContactsFragment。
FragmentTab1片段類:
public class FragmentTab1 extends SherlockFragment implements OnClickListener {
Button btnTest;
ViewPager pager;
LinearLayout layoutBlockNumbers;
LinearLayout layoutContact, layoutCallLog, layoutSMSLog, layoutManually;
Context context;
CustomizedDialog dialog;
private static final int CONTACT_PICKER_RESULT = 1001;
private static final String DEBUG_TAG = "Contact List";
private static final double RESULT_OK = -1;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragmenttab1, container,
false);
layoutBlockNumbers = (LinearLayout) rootView
.findViewById(R.id.layoutAddBlockNumbers);
layoutBlockNumbers.setOnClickListener(this);
return rootView;
}
@Override
public void onClick(View v) {
if (v == layoutCallLog) {
dialog.dismiss();
// want to replace new fragment at position 0 in pager
// problem is here ??? how to open new fragmnet
Fragment allContactsFragment = AllContactsFragment.newInstance();
FragmentTransaction transaction = getChildFragmentManager()
.beginTransaction();
transaction.addToBackStack(null);
transaction.replace(R.id.pager, allContactsFragment).commit();
}
if (v == layoutBlockNumbers) {
// open a dialog
showDialog();
} else if (v == layoutContact) {
openContactList();
dialog.dismiss();
} else if (v == layoutSMSLog) {
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
setUserVisibleHint(true);
}
// open a dialog
private void showDialog() {
dialog = new CustomizedDialog(getActivity());
dialog.setContentView(R.layout.dialog_add_number_type);
dialog.setTitle("Add Black List Number");
//initialize all linear layouts in dialog
layoutCallLog = (LinearLayout) dialog.findViewById(R.id.layoutCallLog);
layoutContact = (LinearLayout) dialog.findViewById(R.id.layoutContact);
layoutSMSLog = (LinearLayout) dialog.findViewById(R.id.layoutSMSLog);
layoutManually = (LinearLayout) dialog
.findViewById(R.id.layoutManually);
// add listener to several linear layout
layoutContact.setOnClickListener(this);
layoutCallLog.setOnClickListener(this);
layoutSMSLog.setOnClickListener(this);
layoutManually.setOnClickListener(this);
dialog.show();
}
public static Fragment newInstance() {
Fragment f = new FragmentTab1();
return f;
}
}
activity_main.xml中看起來象下面這樣:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</android.support.v4.view.ViewPager>
</RelativeLayout>
能有人能幫助我解決這個問題?很抱歉,海量代碼。
感謝您快速回答。我正在檢查.. –
其中我在列表中添加片段?在我的場景中添加如何?我很困擾。認爲我是一名初級程序員。 –
我已經添加了舊的片段列表,它運作良好。但我的問題是如何在對話框onclick事件中打開新片段?@Rarw –
