EditMainMenulistview.java
public class EditMainMenulistview extends BaseAdapter {
protected static Context Context = null;
int i;
public String editnewmainmenu, menuname,edittext;
String qrimage;
Bitmap bmp, resizedbitmap;
Bitmap[] bmps;
Activity activity = null;
private LayoutInflater inflater;
private ImageView[] mImages;
String[] itemimage;
TextView[] tv;
String itemname, itemcode;
public String[] itemnames, itemcodes;
HashMap<String, String> map = new HashMap<String, String>();
public EditMainMenulistview(Context context, JSONArray imageArrayJson) {
Context = context;
// inflater =
// (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// imageLoader=new ImageLoader(activity);
inflater = LayoutInflater.from(context);
this.mImages = new ImageView[imageArrayJson.length()];
this.bmps = new Bitmap[imageArrayJson.length()];
this.itemnames = new String[imageArrayJson.length()];
this.itemcodes = new String[imageArrayJson.length()];
try {
for (i = 0; i < imageArrayJson.length(); i++) {
JSONObject image = imageArrayJson.getJSONObject(i);
qrimage = image.getString("menuimage");
itemname = image.getString("menuname");
itemcode = image.getString("menucode");
itemnames[i] = itemname;
itemcodes[i] = itemcode;
byte[] qrimageBytes = Base64.decode(qrimage.getBytes());
bmp = BitmapFactory.decodeByteArray(qrimageBytes, 0,
qrimageBytes.length);
int width = 100;
int height = 100;
resizedbitmap = Bitmap.createScaledBitmap(bmp, width, height,
true);
bmps[i] = bmp;
mImages[i] = new ImageView(context);
mImages[i].setImageBitmap(resizedbitmap);
mImages[i].setScaleType(ImageView.ScaleType.FIT_START);
// tv[i].setText(itemname);
}
System.out.println(itemnames[i]);
System.out.println(map);
} catch (Exception e) {
// TODO: handle exception
}
}
public int getCount() {
return mImages.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
vi = inflater.inflate(R.layout.editmainmenulist, null);
EditText text = (EditText) vi.findViewById(R.id.editmaimenu);
ImageView image = (ImageView) vi.findViewById(R.id.menuimage);
image.setImageBitmap(bmps[position]);
text.append(itemnames[position]);
edittext = text.getText().toString();
System.out.println(edittext);
//Toast.makeText(Context, edittext, Toast.LENGTH_LONG).show();
return vi;
}
}
what i am changed text in EditMaiMenulisview i click button(Update) Main.java i want print what i have been changed in Edittext. please replay
Please use the following code
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
if(vi == null) {
vi = inflater.inflate(R.layout.editmainmenulist, null);
}
EditText text = (EditText) vi.findViewById(R.id.editmaimenu);
ImageView image = (ImageView) vi.findViewById(R.id.menuimage);
TextView tv = (TextView) vi.findViewById(R.id.<textViewId>); //replace with
//textView ID
image.setImageBitmap(bmps[position]);
text.append(itemnames[position]);
edittext = text.getText().toString();
text.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
Log.v("LOG","After text change value "+s.toString());
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
// TODO Auto-generated method stub
}
});
System.out.println(edittext);
//Toast.makeText(Context, edittext, Toast.LENGTH_LONG).show();
tv.setText(edittext);
return vi;
}
You can get the value in afterTextChange method
change getView to:
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
if(vi == null) {
vi = inflater.inflate(R.layout.editmainmenulist, null);
}
EditText text = (EditText) vi.findViewById(R.id.editmaimenu);
ImageView image = (ImageView) vi.findViewById(R.id.menuimage);
TextView tv = (TextView) vi.findViewById(R.id.<textViewId>); //replace with
//textView ID
image.setImageBitmap(bmps[position]);
text.append(itemnames[position]);
edittext = text.getText().toString();
System.out.println(edittext);
//Toast.makeText(Context, edittext, Toast.LENGTH_LONG).show();
tv.setText(edittext);
return vi;
}
if some of the items in your listview changed you should call adapter.notifyDataSetChanged();
