だから私はタブを使用して、この種のナビゲーションを求めています:
tab1 -- > 内部 1 -- > 内部 2
tab2 --> 3 の内側 --> 4 の内側
tab3 -- > 5 の内側
内部では、新しいレイアウトとクラスを開く必要があることを意味します。
私のプロジェクトのメインクラスはこれです:
public class TabsFragmentActivity extends SherlockFragmentActivity implements
TabHost.OnTabChangeListener {
private TabHost mTabHost;
private HashMap<String, TabInfo> mapTabInfo = new HashMap<String, TabInfo>();
private TabInfo mLastTab = null;
private static Context mContext;
private class TabInfo {
private String tag;
private Class clss;
private Bundle args;
private Fragment fragment;
TabInfo(String tag, Class clazz, Bundle args) {
this.tag = tag;
this.clss = clazz;
this.args = args;
}
}
class TabFactory implements TabContentFactory {
private final Context mContext;
public TabFactory(Context context) {
mContext = context;
}
public View createTabContent(String tag) {
View v = new View(mContext);
v.setMinimumWidth(0);
v.setMinimumHeight(0);
return v;
}
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Step 1: Inflate layout
setContentView(R.layout.tabs_fragment_activity);
mContext = this;
// Step 2: Setup TabHost
initialiseTabHost(savedInstanceState);
if (savedInstanceState != null) {
mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab"));
}
addNavaigationBar();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
//Add Action item with title
menu.add("some")
.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
return super.onCreateOptionsMenu(menu);
}
public void addNavaigationBar() {
// Create Action Bar sherlock
ActionBar navigation_bar = getSupportActionBar();
// Setting standart navigation bar view
navigation_bar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
navigation_bar.setDisplayShowTitleEnabled(true);
navigation_bar.setTitle("Test");
// Override Action items to navigation bar. Calls onCreateOptionsMenu
// invalidateOptionsMenu();
}
protected void onSaveInstanceState(Bundle outState) {
outState.putString("tab", mTabHost.getCurrentTabTag()); // save the tab
// selected
super.onSaveInstanceState(outState);
}
/**
* Step 2: Setup TabHost
*/
private void initialiseTabHost(Bundle args) {
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
TabInfo tabInfo = null;
TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost
.newTabSpec("Tab1").setIndicator("Tab 1"),
(tabInfo = new TabInfo("Tab1", Tab1Fragment.class, args)));
this.mapTabInfo.put(tabInfo.tag, tabInfo);
TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost
.newTabSpec("Tab2").setIndicator("Tab 2"),
(tabInfo = new TabInfo("Tab2", Tab2Fragment.class, args)));
this.mapTabInfo.put(tabInfo.tag, tabInfo);
TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost
.newTabSpec("Tab3").setIndicator("Tab 3"),
(tabInfo = new TabInfo("Tab3", Tab3Fragment.class, args)));
this.mapTabInfo.put(tabInfo.tag, tabInfo);
// Default to first tab
this.onTabChanged("Tab1");
//
mTabHost.setOnTabChangedListener(this);
}
private static void addTab(TabsFragmentActivity activity, TabHost tabHost,
TabHost.TabSpec tabSpec, TabInfo tabInfo) {
// Attach a Tab view factory to the spec
tabSpec.setContent(activity.new TabFactory(activity));
String tag = tabSpec.getTag();
//getTabWidget()
View view = prepareTabView(activity, R.id.tab_bar_icon);
tabSpec.setIndicator(view);
// Check to see if we already have a fragment for this tab, probably
// from a previously saved state. If so, deactivate it, because our
// initial state is that a tab isn't shown.
tabInfo.fragment = activity.getSupportFragmentManager().findFragmentByTag(tag);
if (tabInfo.fragment != null && !tabInfo.fragment.isDetached()) {
FragmentTransaction ft = activity.getSupportFragmentManager().beginTransaction();
ft.detach(tabInfo.fragment);
ft.commit();
activity.getSupportFragmentManager().executePendingTransactions();
}
tabHost.addTab(tabSpec);
}
private static View prepareTabView(Context context, int drawable){
//inflate(R.layout.tab_indicator, android.R.id.tabs, false)
View tabIndicator = LayoutInflater.from(context).inflate(R.layout.tab_indicator, null);
ImageView icon = (ImageView) tabIndicator.findViewById(R.id.tab_bar_icon);
icon.setImageResource(R.drawable.ic_launcher);
return tabIndicator;
}
public void onTabChanged(String tag) {
TabInfo newTab = this.mapTabInfo.get(tag);
if (mLastTab != newTab) {
FragmentTransaction ft = this.getSupportFragmentManager()
.beginTransaction();
if (mLastTab != null) {
if (mLastTab.fragment != null) {
ft.detach(mLastTab.fragment);
}
}
if (newTab != null) {
if (newTab.fragment == null) {
newTab.fragment = Fragment.instantiate(this,
newTab.clss.getName(), newTab.args);
ft.add(R.id.realtabcontent, newTab.fragment, newTab.tag);
} else {
ft.attach(newTab.fragment);
}
}
mLastTab = newTab;
ft.commit();
this.getSupportFragmentManager().executePendingTransactions();
}
}
}
これにより、コンテンツが含まれる 3 つのタブが作成されます。Tab1フラグメントクラスの外観は次のとおりです（他の外観も同様です）：
public class Tab1Fragment extends SherlockFragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
// We have different layouts, and in one of them this
// fragment's containing frame doesn't exist. The fragment
// may still be created from its saved state, but there is
// no reason to try to create its view hierarchy because it
// won't be displayed. Note this is not needed -- we could
// just run the code below, where we would create and return
// the view hierarchy; it would just never be used.
return null;
}
LinearLayout theLayout = (LinearLayout)inflater.inflate(R.layout.tab_frag1_layout, container, false);
// Register for the Button.OnClick event
Button b = (Button)theLayout.findViewById(R.id.frag1_button);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
**//Here i want open a new window but don't change pressed tab and when press back it should go back at this window**
}
});
return theLayout;
}
}
ボタンを押して書きたいことを書きます。
このフラグメント内で新しいフラグメントまたはアクティビティを開くことができませんか?
フラグメント内でナビゲーションを行うにはどうすればよいですか?
