You are doing something wrong with your tabs. Are you just launching a new activity when the tab is clicked? Then, if that new activitys layout covers the entire screen, ofcourse the tabs will be covered by this.
Follow this guide: http://developer.android.com/intl/de/resources/tutorials/views/hello-tabwidget.html
Here is some information.. screen2.xml
<?xml version="1.0" encoding="utf-8"?>
screen1.xml
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#c6c3c6"
android:layout_gravity="bottom"
android:paddingTop="1dip"
android:paddingLeft="1dip"
android:paddingRight="1dip">
<TabWidget
android:layout_gravity="bottom"
android:id="@android:id/tabs"
android:layout_height="wrap_content"
android:layout_width="fill_parent"/>
</FrameLayout>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
</TabHost>
MainActivity.java
public class onstarAndroidMain extends TabActivity {
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.screen1);
addTabs();
}
private void addTabs(){
Resources resources = getResources();
TabHost tabs = (TabHost) findViewById(android.R.id.tabhost);
tabs.setup();
//tabspec defines the attributes of the tab
TabSpec tab;
tab = tabs.newTabSpec("Screen1");
tab.setContent(new Intent(this, Screen1.class));
tab.setIndicator("Screen1");
tabs.addTab(tab);
tabs.getTabWidget().getChildAt(0).getLayoutParams().height = 30;
tab = tabs.newTabSpec("Screen2");
tab.setContent(new Intent(this, Screen2.class));
tab.setIndicator("Screen2");
tabs.addTab(tab);
tabs.getTabWidget().getChildAt(1).getLayoutParams().height = 30;
tab = tabs.newTabSpec("Screen3");
tab.setContent(new Intent(this, Screen3.class));
tab.setIndicator("Screen3");
tabs.addTab(tab);
tabs.getTabWidget().getChildAt(2).getLayoutParams().height = 30;
//sets the current tab
tabs.setCurrentTab(0);
//add the tabhost to the main content view
}
}
Screen2.java
public class OnstarScreen2 extends Activity {
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.screen2);
}
Now whenever I click the screen2 tab and try to get the screen2.xml, my tabs are going below the screen2 layout. I dont know what to do. Basically what I want to achieve is that the tab should be always their at the bottom irrespective of what view is shown above them. they should not be overlapped with anything else.
screen2.xml has a scrollview and iside that I have a linearlayout which has a login form...but this form whenever is called just comes above the tabs...please help
