[英]ActionBarSherlock overlapping on tab navigation and ActionMode
使用選項卡導航和操作模式,ActionBarSherlock出現了一個奇怪的問題。
重復問題很簡單,我使用演示代碼生成以下示例活動:
import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.view.ActionMode;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
public class MainActivity extends SherlockFragmentActivity implements ActionBar.TabListener {
private ActionMode actionMode = null;
@Override
public void onCreate(Bundle savedInstanceState) {
setTheme(com.actionbarsherlock.R.style.Theme_Sherlock);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
for (int i = 1; i <= 2; i++) {
ActionBar.Tab tab = getSupportActionBar().newTab();
tab.setText("Tab " + i);
tab.setTabListener(this);
getSupportActionBar().addTab(tab);
}
actionMode = startActionMode(new TestActionMode());
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
private final class TestActionMode implements ActionMode.Callback {
@Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
menu.add("Add").setIcon(android.R.drawable.ic_input_add).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
menu.add("Search").setIcon(android.R.drawable.ic_search_category_default).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
return true;
}
@Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
// TODO Auto-generated method stub
return false;
}
@Override
public void onDestroyActionMode(ActionMode mode) {
// TODO Auto-generated method stub
}
}
}
它在Android 4.0(在真實設備和仿真器上測試)上正常工作,但是在Jelly Bean(僅在仿真器上測試)上,我有以下行為。
有時(但很少),所有功能都可以完美運行,尤其是當我在Dev中啟用了所有動畫時。 設置(通常我禁用所有動畫)。
我正在使用ActionBarSherlock 4.4。
任何建議將不勝感激,因為我真的不明白我在哪里犯了錯誤。
謝謝並恭祝安康。
我最近遇到了同樣的問題。 在浪費了幾天之后,發現這種奇怪的行為是由本期中描述的UX缺陷引起的,並且實際上與ABS(動作欄Sherlock)無關。
最可靠的解決方法似乎是使用反射來控制應如何呈現操作欄:
/**
* On Android 3.0 and above, while using the ActionBar tabbed navigation style, the tabs sometimes appear above the action bar.
* This helper method allows you to control the 'hasEmbeddedTabs' behaviour.
* A value of true will put the tabs inside the ActionBar, a value of false will put it above or below the ActionBar.
*
* You should call this method while initialising your ActionBar tabs.
* Don't forget to also call this method during orientation changes (in the onConfigurationChanged() method).
*
* @param inActionBar
* @param inHasEmbeddedTabs
*/
public static void setHasEmbeddedTabs(Object inActionBar, final boolean inHasEmbeddedTabs)
{
// get the ActionBar class
Class<?> actionBarClass = inActionBar.getClass();
// if it is a Jelly Bean implementation (ActionBarImplJB), get the super class (ActionBarImplICS)
if ("android.support.v7.app.ActionBarImplJB".equals(actionBarClass.getName()))
{
actionBarClass = actionBarClass.getSuperclass();
}
try
{
// try to get the mActionBar field, because the current ActionBar is probably just a wrapper Class
// if this fails, no worries, this will be an instance of the native ActionBar class or from the ActionBarImplBase class
final Field actionBarField = actionBarClass.getDeclaredField("mActionBar");
actionBarField.setAccessible(true);
inActionBar = actionBarField.get(inActionBar);
actionBarClass = inActionBar.getClass();
}
catch (IllegalAccessException e) {}
catch (IllegalArgumentException e) {}
catch (NoSuchFieldException e) {}
try
{
// now call the method setHasEmbeddedTabs, this will put the tabs inside the ActionBar
// if this fails, you're on you own <img src="http://www.blogc.at/wp-includes/images/smilies/icon_wink.gif" alt=";-)" class="wp-smiley">
final Method method = actionBarClass.getDeclaredMethod("setHasEmbeddedTabs", new Class[] { Boolean.TYPE });
method.setAccessible(true);
method.invoke(inActionBar, new Object[]{ inHasEmbeddedTabs });
}
catch (NoSuchMethodException e) {}
catch (InvocationTargetException e) {}
catch (IllegalAccessException e) {}
catch (IllegalArgumentException e) {}
}
