You have to use the Spinner like these below:
Spinner spin = (Spinner) findViewById(R.id.spinner);
spin.setOnItemSelectedListener(this);
ArrayAdapter aa = new ArrayAdapter(this,R.layout.spinner_item,ARRAYLIST_DATA_HERE);
aa.setDropDownViewResource(R.layout.spinner_item);
//Setting the ArrayAdapter data on the Spinner
spin.setAdapter(aa);
spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String items=spinner.getSelectedItem().toString();
Log.i("Selected item : ",items);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
return true;
Use the spinner_item xml
xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#BAB7BA"
android:ellipsize="start"
android:gravity="left"
android:padding="10dip"
android:textColor="#color/white" />
Did you check On Click Listener for your ListView ?? I think that will solve your problem.. Use onClikcListener's on ItemClick event which will give you position and based on that position you can get item from your Arraylist which will give you id from that..

I tried to make a simple application that will take the API from the internet, rearrange them and show as list.
In the emulator it works. The phone shows a white screen. The phone has Android 2.3.7. But when I tried it on the tablet, the app stopped working. The tablet has Android 4.1.
