Can specific point, I was a rookie.
My code:
ScoreInformation.java

public class ScoreInformation extends Activity {
private ListView lv;
/ ** Called when the activity is first created. * /
@ Override
public void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);

ArrayList > mylist = new ArrayList > ();
HashMap map = new HashMap ();
map.put ("ID", "Student ID");
map.put ("Name", "name");
map.put ("Course", "subject");
map.put ("Score", "result");
mylist.add (map);
for (int i = 0; i int j = 0;
HashMap map1 = new HashMap ();
map1.put ("ID", Datainfo.data [j + +] [i]);
map1.put ("Name", Datainfo.data [j + +] [i]);
map1.put ("Course", Teacherinfo.course);
if (Datainfo.data [j + +] [i]. equals ("null")) {
map1.put ("Score", "");
} Else {
map1.put ("Score", Datainfo.data [j + +] [i]);
}
mylist.add (map1);
}

SpecialAdapter adapter = new SpecialAdapter (this, mylist, R.layout.scoreinformation,
new String [] {"ID", "Name", "Course", "Score"},
new int [] {R.id.tv1, R.id.tv2, R.id.tv3, R.id.tv4}
);

lv = new ListView (this);
lv.setHorizontalScrollBarEnabled (true);
lv.setAdapter (adapter);
HorizontalScrollView hsv = new HorizontalScrollView (this);
hsv.addView (lv);
setContentView (hsv);
}
}
Where "tv4" is the record score EditText

SpecialAdapter.java
public class SpecialAdapter extends SimpleAdapter {
private int [] colors = new int [] {
0x30FF0000, 0x300000FF
};
public SpecialAdapter (Context context, List > data,
int resource, String [] from, int [] to) {
super (context, data, resource, from, to);
/ / TODO Auto-generated constructor stub
}

@ Override
public View getView (int position, View convertView, ViewGroup parent) {
View view = super.getView (position, convertView, parent);
int colorPos = position% colors.length;
if (colorPos == 1) {
view.setBackgroundColor (Color.argb (250, 255, 255, 255));
} Else {
view.setBackgroundColor (Color.argb (250, 224, 243, 250));
}
return view;
}
}

Create an EditText of two-digit group and then use a for loop dynamic layout for each array member setTag (key, value); You can set each of the relevant information, then you can listen

On the second question is basically solved EditText array of dynamic applications each set Listener
The first question we have suggested is not?
Elaborate on this issue:
Appears after clicking edittext soft keyboard then click the back button under normal circumstances should you just fill in the characters appear in the soft keyboard disappears edittext but the reality is that after clicking the
edittext is empty

Today, the words encountered the same problem with the landlord, and later even to solve, the code made up, in the hope that in the future to help people
The main idea is to customize an adapter, the adapter found editText on editText add a text change event detection. There will be modified before the event, when modified, the modified parameters, find the desired saved enough.
The above has put you much about it, just simple code code, we hope inspire

class mylistphone {
private TextView tv;
private EditText ed;

}
class myAdapter extends BaseAdapter {
private Context ctx;
private ArrayList al;
private String myend;
private LayoutInflater in;
public myAdapter (Context ctx, ArrayList al) {
this.ctx = ctx;
this.al = al;
}
public int getCount () {
return al.size ();
}

@ Override
public Object getItem (int position) {
return al.get (position);
}

@ Override
public long getItemId (int position) {
return position;
}

@ Override
public View getView (int position, View view, ViewGroup parent) {
/ / String after = "";
/ / Final StringBuffer sb = new StringBuffer ();
mylistphone mylist = new mylistphone ();
in = LayoutInflater.from (ctx);
View v = in.inflate (R.layout.lvphone, null);
mylist.tv = (TextView) v.findViewById (R.id.tvlvphonetype);
mylist.ed = (EditText) v.findViewById (R.id.edlvphonenumber);
mylist.tv.setText (((HashMap) al.get (position)) get ("type") toString ()..);
. String be = ((HashMap) al.get (position)) get ("phonenumber") toString ();.
mylist.ed.setText (((HashMap) al.get (position)) get ("phonenumber") toString ()..);
mylist.ed.addTextChangedListener (new TextWatcher () {
public void onTextChanged (CharSequence s, int start, int before, int count) {
/ / System.out.println ("s:" + s + ", start:" + start + ", before:" + before + ", count:" + count);
}
public void beforeTextChanged (CharSequence s, int start, int count,
int after) {
/ / System.out.println ("s:" + s + ", start:" + start + ", after:" + after + ", count:" + count);
}
public void afterTextChanged (Editable s) {
/ / System.out.println (s.toString ());
/ / Sb.append (s.toString ());
myend = s.toString ();
}
});

if (be.equals (myend) | | myend == null | | myend == "") {
/ / Mylist.ed.setText (myend);
myend = "";
} Else {
/ / System.out.println (myend + ", ttttttttttttttttt");
mylist.ed.setText (myend);
myend = "";
}

return v;
}
