을하고있어 무엇
intent = new Intent().setClass(this, CustomActivityGroup.class);
spec = tabHost.newTabSpec("tab_2").setIndicator("Sign up",getResources().getDrawable(R.drawable.signup)).setContent(intent);
tabHost.addTab(spec);
하지만 탭을 해당 클릭 할 때 내가 얻을 :
public class CustomActivityGroup extends ActivityGroup {
View rootView;
public static CustomActivityGroup 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("LoginActivity", new Intent(this,RegisterActivity.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
replaceView(view);
}
@Override
protected void onResume() {
super.onResume();
this.history = new ArrayList<View>();
group = this;
}
public void replaceView(View v) {
if (history.size() == 0) {
if (rootView != null) {
history.add(rootView);
rootView = null;
}
}
history.add(v);
setContentView(v);
}
public void back() {
try {
if (history.size() > 0) {
history.remove(history.size() - 1);
if (history.size() > 0) {
setContentView(history.get(history.size() - 1));
} else {
finish();
}
} else {
finish();
}
} catch (Exception ex) {
}
}
public int getHistorySize() {
return history.size();
}
@Override
public void onBackPressed() {
try {
CustomActivityGroup.group.back();
} catch (Exception ex) {
}
return;
}
}
내 TabActivity에서
: 나는 그런 ActivityGroup 클래스를 사용할 수 있습니까?

처럼 만들어야합니다 .. – aditya
