I have a problem with EditText
fields in a ListActivity
.
The code complies all right, but the functionality is strange, typing in the first field and hiding the keyboard after this the text appears in another editfield.
Help me with my logical issue
package com.example.helloandroid;
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.EditText;
import android.widget.TextView;
public class AddComp extends ListActivity {
static final int DATE_DIALOG_ID = 0;
private class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private String[] attitude_names;
private String[] attitude_values;
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
attitude_names = context.getResources().getStringArray(R.array.COMP_ATTITUDE_NAME);
attitude_values = new String[attitude_names.length];
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.addcomp_attitude_row, null);
holder = new ViewHolder();
holder.Attitude_Name = (TextView) convertView.findViewById(R.id.addcomp_att_name);
holder.Attitude_Value = (EditText) convertView.findViewById(R.id.addcomp_att_value);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.Attitude_Name.setText(attitude_names[position]);
holder.Attitude_Value.setHint(attitude_names[position]);
attitude_values[position] = holder.Attitude_Value.getText().toString();
return convertView;
}
class ViewHolder {
TextView Attitude_Name;
EditText Attitude_Value;
}
@Override
public int getCount() {
return attitude_names.length;
}
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new EfficientAdapter(this));
setContentView(R.layout.addcomp);
}
}
I found the reason the behaviour of the strange focusing one has to add
android:windowSoftInputMode="adjustPan"
as value to the activity in the Projects Manifest but on the other hand the problem that often more than one value of the edidfield is changed is not solved rightnowProblem solved by adding Entry in manifest and the use of a
TextWatcher
(this is needed because the view of one list row is internly called several times that means that for 500 list entries the programm uses only afew intances of the row.view-class to be mor efficient) therfore it is need to use a text watcher that saves the changed data in a extra datastructur for exsample an array..This will help you

Here I have included a HashMap object which will keep on eye of what EditText contains value.And when you scroll the listview,it will be rendered again by calling its getView method.
In this code,when you firstly load listview,all your edittext will be with no text.once you enter some text,it will be noted in myList.So when you again render the list,your text would be prevented.
