我的問題是切換標籤使用活動組它要顯示上次活動。 我想顯示最後打開/訪問屏幕，當我們瀏覽tab.My一個是去第一個畫面：切換標籤使用活動組它想要顯示上次活動
這是我maninActivity」
public class MainActivity extends TabActivity {
int selectedTab;
TabHost tabHost ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabview);
TabHost t = getTabHost();
tabHost = (TabHost)findViewById(android.R.id.tabhost);
Resources res = getResources();
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
TabSpec thirdTabSpec = tabHost.newTabSpec("tid1");
TabSpec fouthTabSpec = tabHost.newTabSpec("tid1");
/** TabSpec setIndicator() is used to set name for the tab. */
/** TabSpec setContent() is used to set content for a particular tab. */
firstTabSpec.setIndicator("Sales",res.getDrawable(R.drawable.ic_tab_artists_grey)).setContent(new Intent(this,SalesActivityGroup.class));
secondTabSpec.setIndicator("Admin",res.getDrawable(R.drawable.admin)).setContent(new Intent(this,SettingActivityGroup.class));
thirdTabSpec.setIndicator("Setting",res.getDrawable(R.drawable.ic_tab_artists_grey)).setContent(new Intent(this,SettingActivityGroup.class));
fouthTabSpec.setIndicator("Inquiry",res.getDrawable(R.drawable.ic_tab_artists_grey)).setContent(new Intent(this,SettingActivityGroup.class));
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(thirdTabSpec);
tabHost.addTab(fouthTabSpec);
tabHost.setCurrentTab(0);
tabHost.setMinimumHeight(18);
tabHost.setFadingEdgeLength(5);
}
public void onTabChanged(String arg0) {
selectedTab = tabHost.getCurrentTab();
}
}
這是我SalesActivityGroup
public class SalesActivityGroup extends ActivityGroup {
public static SalesActivityGroup group;
private ArrayList<View> history;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.history = new ArrayList<View>();
group = this;
View view = getLocalActivityManager().startActivity("Sales",
new Intent(this, SalesRouteActivity.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
replaceView(view);
}
public void replaceView(View v) {
history.add(v);
setContentView(v);
}
public void back() {
if (history.size() > 0) {
history.remove(history.size() - 1);
if (history.size() > 0) {
setContentView(history.get(history.size() - 1));
} else {
finish();
}
} else {
finish();
}
}
public void backToFirst() {
int size = history.size();
while (size > 1) {
history.remove(size - 1);
size = history.size();
}
setContentView(history.get(0));
}
@Override
public void onBackPressed() {
SalesActivityGroup.group.back();
return;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// super.onActivityResult(requestCode, resultCode, data);
Log.i("****" , "requestCode" + requestCode);
Bundle bundle = data.getExtras();
String roteCode = bundle.getString("RouteCode");
Intent intent = new Intent(SalesActivityGroup.this,ListRetailerActivity.class);
bundle.putString("RouteCode", roteCode);
intent.putExtras(bundle);
View view = SalesActivityGroup.group.getLocalActivityManager()
.startActivity("",intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
SalesActivityGroup.group.replaceView(view);
}
}
這是我在SalesRouteActivity的電話部分
Intent intent = new Intent(SalesRouteActivity.this, ListRetailerActivity.class);
Bundle bundle = new Bundle();
bundle.putString("RouteName", keyword);
intent.putExtras(bundle);
View view = SalesActivityGroup.group.getLocalActivityManager().startActivity("", intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
SalesActivityGroup.group.replaceView(view);
S我喜歡上面的代碼，我有設置ActivityGroup爲下一個標籤
public class SettingActivityGroup extends ActivityGroup {
// Keep this in a static variable to make it accessible for all the nested
// activities, lets them manipulate the view
public static SettingActivityGroup group;
// Need to keep track of the history if you want the back-button to work
// properly, don't use this if your activities requires a lot of memory.
private ArrayList<View> history;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.history = new ArrayList<View>();
group = this;
// Start the root activity withing the group and get its view
View view = getLocalActivityManager().startActivity(
"Setting",
new Intent(this, SettingScreenActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Replace the view of this ActivityGroup
replaceView(view);
}
public void replaceView(View v) {
// Adds the old one to history
history.add(v);
// Changes this Groups View to the new View.
setContentView(v);
}
public void back() {
if (history.size() > 0) {
history.remove(history.size() - 1);
if (history.size() > 0) {
setContentView(history.get(history.size() - 1));
} else {
finish();
}
} else {
finish();
}
}
@Override
public void onBackPressed() {
SettingActivityGroup.group.back();
return;
}
}
我粘貼我的代碼在這裏。 http://pastebin.com/D4fvkGBx
我面臨這樣的麻煩......
請幫我
哪裏是錯誤的，我的代碼？
在此先感謝
的ActivityGroup已過時，使用新的片段和FragmentManager的API來代替。 – pgsandstrom
