請寫下面的代碼，它會解決你的問題。
ActivityStack.java
private Stack<String> stack;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (stack == null)
stack = new Stack<String>();
// start default activity
push("FirstStackActivity", new Intent(this, Tab_SampleActivity.class));
}
@Override
public void finishFromChild(Activity child) {
pop();
}
@Override
public void onBackPressed() {
pop();
}
public void push(String id, Intent intent) {
Window window = getLocalActivityManager().startActivity(id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
if (window != null) {
stack.push(id);
setContentView(window.getDecorView());
}
}
public void pop() {
if (stack.size() == 1)
finish();
LocalActivityManager manager = getLocalActivityManager();
manager.destroyActivity(stack.pop(), true);
if (stack.size() > 0) {
Intent lastIntent = manager.getActivity(stack.peek()).getIntent();
Window newWindow = manager.startActivity(stack.peek(), lastIntent);
setContentView(newWindow.getDecorView());
}
}
TabActivity.java
public class TabActivity extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_screen);
TabHost tabHost = getTabHost();
Intent intent = new Intent().setClass(this, ActivityStack.class);
TabHost.TabSpec spec = tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.home));
spec.setContent(intent);
tabHost.addTab(spec);
Intent intent1 = new Intent().setClass(this, ActivityStack.class);
TabHost.TabSpec spec1 = tabHost.newTabSpec("tabId").setIndicator("Temp", getResources().getDrawable(R.drawable.invoice));
spec1.setContent(intent1);
tabHost.addTab(spec1);
tabHost.setCurrentTab(0);
}
}
FirstActivity.java
public class FirstActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
textView.setText("Tab Sample Activity ");
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(getParent(), SecondActivity.class);
ActivityStack activityStack = (ActivityStack) getParent();
activityStack.push("SecondActivity", intent);
}
});
setContentView(textView);
}
}
SecondActivity.java
public class SecondActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
textView.setText("First Stack Activity ");
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(getParent(), ThirdActivity.class);
ActivityStack activityStack = (ActivityStack) getParent();
activityStack.push("ThirdActivity", intent);
}
});
setContentView(textView);
}
}
ThirdActivity.java
public class ThirdActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
