I would like to have your guidance to solve a problem that i have with my
first android app (SlidingTabLayout) I have the following
ViewPagerAdapter.java
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
/**
* Created by John on 6/12/2015.
*/
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
CharSequence Titles[]; // This will Store the Titles of the Tabs which are
Going to be passed when ViewPagerAdapter is created
int NumbOfTabs; // Store the number of tabs, this will also be passed when
the ViewPagerAdapter is created
// Build a Constructor and assign the passed Values to appropriate values
in the class
public ViewPagerAdapter(FragmentManager fm, CharSequence mTitles[], int
mNumbOfTabsumb) {
super(fm);
this.Titles = mTitles;
this.NumbOfTabs = mNumbOfTabsumb;
}
//This method return the fragment for the every position in the View Pager
@Override
public Fragment getItem(int position) {
return Tab_Modes.init(position);
}
// This method return the titles for the Tabs in the Tab Strip
@Override
public CharSequence getPageTitle(int position) {
return Titles[position];
}
// This method return the Number of tabs for the tabs Strip
@Override
public int getCount() {
return NumbOfTabs;
}
}
The custom data structure class
/**
* Created by John on 7/22/2015.
*/
public class NameImg {
public String itemName;
public String itemDesc;
public int itemImg;
public NameImg() {
super();
}
public NameImg(String itemName, String itemDesc, int itemImg) {
super();
this.itemName = itemName;
this.itemDesc = itemDesc;
this.itemImg = itemImg;
}
public String getName() {
return this.itemName;
}
public void setName(String itemName) {
this.itemName = itemName;
}
public String getDesc() {
return this.itemDesc;
}
public void setDesc(String itemDesc) {
this.itemDesc = itemDesc;
}
public int getImg() {
return this.itemImg;
}
public void setImg(int itemImg) {
this.itemImg = itemImg;
}
}
and the tab
/**
* Created by John on 6/12/2015.
*/
public class Tab_Modes extends Fragment {
int tab_idx;
private ListView myLV;
static Tab_Modes init(int val) {
Tab_Modes myTab = new Tab_Modes();
// Supply val input as an argument.
Bundle args = new Bundle();
args.putInt("val", val);
myTab.setArguments(args);
return myTab;
}
/**
* Retrieving this instance's number from its arguments.
*/
public void onCreate(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState) {
// super.onCreate(savedInstanceState);
tab_idx = getArguments() != null ? getArguments().getInt("val") : 1;
NameImg usb[] = new NameImg[]
{
new NameImg("1", "USB1", R.drawable.hand),
new NameImg("2", "USB2", R.drawable.bulb),
new NameImg("3", "USB3", R.drawable.bullet)
};
NameImg[][] list_NameImg = new NameImg[][]{basic, spi, i2c, usb};
ModesLvAdapter adapter = new ModesLvAdapter(this, R.layout.my_list,
list_NameImg[tab_idx][]);
myLV = (ListView) myLV.findViewById(R.id.customListView);
View v = inflater.inflate(R.layout.my_list, null);
myLV.setAdapter(adapter);
}
}
The activity_main.xml
LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";

android:layout_width="match_parent"
android:layout_height="match_parent"
