我正在開發具有多個選項卡的android應用程序。Tab開始新活動時消失
現在在啓動器活動標籤顯示完美，並可以瀏覽標籤。 但如果我在按鈕單擊時調用活動（我想顯示爲Tab），則標籤似乎消失。
請參考給定的代碼，讓我知道如果我做錯了什麼。
這是主要TabActivity
public class MyTabActivity extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab);
TabHost tabHost=getTabHost();
TabSpec deshTab=tabHost.newTabSpec("Deshboard");
deshTab.setIndicator("Deshboard");
Intent DeshboardIntent=new Intent(this,DeshboardActivity.class);
deshTab.setContent(DeshboardIntent);
tabHost.addTab(deshTab);
TabSpec clientTab=tabHost.newTabSpec("client");
clientTab.setIndicator("client");
Intent intent=new Intent(this,ClientActivity.class);
clientTab.setContent(intent);
tabHost.addTab(clientTab);
}
}
現在我想開始客戶端活動像
void onButtonClick(View view)
{
int id = view.getId();
switch(id)
{
case R.id.client_btn:
Intent clientIntent = new Intent(DeshboardActivity.this,ClientActivity.class);
startActivity(clientIntent);
break;
}
}
但是當我點擊這個按鈕，它啓動新的活動而不是在標籤。 我應該怎麼做才能在按鈕點擊標籤上顯示此活動？
下面的代碼是ClientActivity我想顯示爲TAB。
public class ClientActivity extends Activity
{
private DatabaseHandler dbHandler;
private ListView clientListView ;
private BaseAdapter listAdapter;
TabHost tabHost;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.clientactivity);
dbHandler = new DatabaseHandler(this);
final List<Client> clientList = dbHandler.getAllclient();
clientListView = (ListView)findViewById(R.id.client_list);
listAdapter = new ClientListAdapter(this, clientList);
clientListView.setAdapter(listAdapter);
clientListView.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id)
{
Client client = clientList.get(position);
Toast.makeText(getApplicationContext(), client.getFirstName(), Toast.LENGTH_LONG).show();
Intent clientInfoIntent = new Intent(getApplicationContext(), ClientInfoActivity.class);
clientInfoIntent.putExtra("client",client);
startActivity(clientInfoIntent);
//finish();
}
});
}
}
