Question

I am trying to change may current Tab. I search for fitting problems but it not solved my own one.
I have a Tab activity like this

<!-- language: java -->   
public class myTabActivity extends TabActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    final TabHost mtabHost = getTabHost();
    int tabnum = getIntent().getIntExtra("currenttab", 0);


    mtabHost.addTab(mtabHost.newTabSpec("tab1")
            .setIndicator("firsttab")
                .setContent(new Intent(this, tabA.class)));
    mtabHost.addTab(mtabHost.newTabSpec("tab1")
            .setIndicator("secondtab")
                .setContent(new Intent(this, tabB.class)));
     setCurrentTab(tabnum);
}
private boolean setCurrentTab(int i) {
    if (getParent() instanceof SimpleSundayScoutUIActivity) {
        ((SimpleSundayScoutUIActivity) getParent()).getTabHost().setCurrentTab(i);
        return true;
    }
    return false;
}

and an activity tabA like this

public class text extends Activity {
myTabActivity mA = (myTabActivity) this.getParent();
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.mainpage);
    Button startbutton= (Button) findViewById(R.id.searchbutton);
    startbutton.setOnClickListener(mNewListener);
}
private OnClickListener mNewListener = new OnClickListener() {

    public void onClick(View v) {
       Intent intent = new Intent(v.getContext(),SimpleSundayScoutUIActivity.class);
       intent.putExtra("currenttab", 1);
       startActivity(intent);
    }
};

means what i want to do is klick on the Button of tabA and then the tab widget should show me tabB but it doesnt work like this

Edited:

Tab class:

public class myTabActivity extends TabActivity {
public static TabHost mtabHost; // change to public static
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
     mtabHost = getTabHost();
    int tabnum = getIntent().getIntExtra("currenttab", 0);


    mtabHost.addTab(mtabHost.newTabSpec("tab1")
            .setIndicator("firsttab")
                .setContent(new Intent(this, tabA.class)));
    mtabHost.addTab(mtabHost.newTabSpec("tab1")
            .setIndicator("secondtab")
                .setContent(new Intent(this, tabB.class)));
     setCurrentTab(tabnum);
}
private boolean setCurrentTab(int i) {
    if (getParent() instanceof SimpleSundayScoutUIActivity) {
        ((SimpleSundayScoutUIActivity) getParent()).getTabHost().setCurrentTab(i);
        return true;
    }
    return false;
}

Button Class:

public class text extends Activity {
myTabActivity mA = (myTabActivity) this.getParent();
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.mainpage);
    Button startbutton= (Button) findViewById(R.id.searchbutton);
    startbutton.setOnClickListener(mNewListener);
}
private OnClickListener mNewListener = new OnClickListener() {

    public void onClick(View v) {
     myTabActivity.mtabHost.setCurrentTab(1); //Remove .this 

    }
};
