我已经实现了选项卡 View 以及水平滑动 View (以更改选项卡)，导航模式作为应用程序的列表。我正在使用 ActionBarSherlock 和 TabPageIndicator。更改标签后，我使用 fragment 重新加载内容。
在下拉微调器中，我有 2 个项目。每当 Activity 重新加载或点击选项卡后，这些都会被选中。
但是，如果执行滑动以选择其他选项卡，则在 Gingerbread 版本中不会触发 onNavigationItemSelected(int position, long itemId) :( 我们已经在 Gingerbread 2.3.6、2.3.3 上进行了测试。
在 logcat 中，我收到了这个 warning 消息 "View:onTouchEvent:ViewFlags"is DISABLED
但是，它在 ICS、Froyo 等上运行良好。
非常感谢您的帮助。
以下是代码 fragment :
public class MainPageActivity extends SherlockFragmentActivity implements
ActionBar.OnNavigationListener {
MenuItem menuItem;
EditText searchText;
public static Context mContext;
public static DataAdapter dataAdapter;
ArrayList<String> accountList;
public static List<View> currentViewBeingChanged = new ArrayList<View>();
public static LayoutInflater layoutInflater;
public static String checktab = "running", nameComp;
int isRefresh;
public static boolean isAutoRefresh = true;
public static ArrayList<String> listItems;
public static boolean check;
public static boolean isAtleastOnce = true, listToBeRefreshed = false;
public static ActionBar actionBar;
public static int itemPosition, listPosition;
public static FragmentManager fragmentManager;
InputMethodManager imm;
@Override
protected void onCreate(Bundle savedInstanceState) {
mContext = this;
layoutInflater = getLayoutInflater();
fragmentManager = getSupportFragmentManager();
super.onCreate(savedInstanceState);
setContentView(R.layout.main_page);
actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
Context context = getSupportActionBar().getThemedContext();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,
android.R.layout.simple_spinner_dropdown_item);
adapter.clear();
for (int i = 0; i < ManageAccountLists.accountList.size(); i++) {
adapter.add(ManageAccountLists.accountList.get(i));
}
actionBar.setListNavigationCallbacks(adapter, this);
tabPagerFunction();
}
public void tabPagerFunction() {
FragmentPagerAdapter adapter = new GoogleMusicAdapter(
getSupportFragmentManager());
adapter.notifyDataSetChanged();
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
checktab = "running";
final TabPageIndicator indicator = (TabPageIndicator) findViewById(R.id.indicator);
indicator.setViewPager(pager);
pager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(int arg0) {
System.out.println("Tab selected..................");
if (arg0 == 0) {
// Running tab is selected
indicator.setCurrentItem(arg0);
checktab = "running";
RunningInstancesActivity runningInstancesActivity = new RunningInstancesActivity();
runningInstancesActivity.callThread();
} else {
// Stopped tab is selected
indicator.setCurrentItem(arg0);
checktab = "stopped";
StoppedInstancesActivity stoppedInstancesActivity = new StoppedInstancesActivity();
stoppedInstancesActivity.callThread();
InstanceStatusUpdate.isOnPostExecute = false;
}
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
class GoogleMusicAdapter extends FragmentPagerAdapter {
private final String[] CONTENT = new String[] { "Running", "Stopped" };
public GoogleMusicAdapter(FragmentManager fm) {
super(fm);
notifyDataSetChanged();
}
@Override
public Fragment getItem(int position) {
switch (position) {
/** Running tab is selected */
case 0:
checktab = "stopped";
return RunningInstancesActivity.newInstance(0);
/** Stopped tab is selected */
case 1:
checktab = "running";
return StoppedInstancesActivity.newInstance(1);
}
return null;
}
@Override
public CharSequence getPageTitle(int position) {
return CONTENT[position % CONTENT.length].toUpperCase();
}
public CharSequence getPageTitle(int position, int number) {
return CONTENT[position % CONTENT.length].toUpperCase();
}
@Override
public int getCount() {
return CONTENT.length;
}
}
@Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
System.out.println("Navigation item selected");
// Performs fetching
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
System.out.println("Dispatch touvh event..");
return super.dispatchTouchEvent(ev);
}
}
最佳答案
尝试这样做
dependencies {
compile "com.android.support:appcompat-v7:18.0.+"
}
并改用支持库。
