Android access content inside TabHost?

Question

Android

Hello. There is an Activity that inherits from TabActivity. There is also an Activity class that is added by the content of the tab. How can I access lvContent from MainActivity class? Thanks in advance! PS I didn't figure out how to format the xml code... sorry.
[xml Activity]

&lt;relativelayout xmlns:tools="<a href="http://schemas.android.com/tools">http://schemas.android.com/tools</a>" xmlns:android="<a href="http://schemas.android.com/apk/res/android">http://schemas.android.com/apk/res/android</a>" android:id="@+id/rlRoot" android:layout_width="match_parent" android:layout_height="match_parent"&gt;&lt;linearlayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"&gt;&lt;tabhost android:id="@android:id/tabhost" android:layout_width="match_parent" android:layout_height="match_parent"&gt;&lt;linearlayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"&gt;&lt;tabwidget android:id="@android:id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" /&gt;&lt;framelayout android:id="@android:id/tabcontent" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#AAFF0000" /&gt;&lt;/linearlayout&gt;&lt;/tabhost&gt;&lt;/linearlayout&gt;&lt;/relativelayout&gt;

[xml content tab]

<?xml version="1.0" encoding="utf-8"?>
&lt;relativelayout xmlns:android="<a href="http://schemas.android.com/apk/res/android">http://schemas.android.com/apk/res/android</a>" android:id="@+id/rlTest" android:layout_width="match_parent" android:layout_height="match_parent"&gt;&lt;listview android:id="@+id/lvContent" android:layout_width="match_parent" android:layout_height="match_parent" /&gt;&lt;/relativelayout&gt;

[initialization code:]

public class MainActivity extends TabActivity {

  public static ListView currentListView;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    
    final TabHost tabHost = getTabHost();
    
    TabHost.TabSpec tabSpec = tabHost.newTabSpec("tag1");
    tabSpec.setContent(new Intent().setClass(this, Tab1.class));
    tabSpec.setIndicator("TAB 1");
    tabHost.addTab(tabSpec);

    tabSpec = tabHost.newTabSpec("tag2");
    tabSpec.setContent(new Intent().setClass(this, Tab1.class));
    tabSpec.setIndicator("TAB 2");
    tabHost.addTab(tabSpec);
    
    tabHost.setCurrentTab(0);
  }
}

Answer 1

Try like this:

// Получаем активити из первого таба
Tab1 tabActivity = (Tab1) getTabHost().getChildAt(0).getContext();
// Вызываем стандартный метод findViewById
ListView list = (ListView) tabActivity.findViewById(R.id. lvContent);
