EditText With ListView.

When we are using EditText in ListView that time we have to implement TextWatcher because you have to add text in your Model/Pojo class after text is entered.

Adapter Class.

I have created one custom baseadapter class for it. In this adapter class i have created one class for TextWatcher because we have to update arraylist after text changed.

package mavya.edittextinlistview;

import android.app.Activity;
import android.content.Context;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.EditText;

import java.util.ArrayList;


/** * Created on 05/01/17. */public class WorkListAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<WorkModel> workModelArrayList;

    public WorkListAdapter(final Context context, final ArrayList<WorkModel> workModelArrayList) {
        this.context = context;
        this.workModelArrayList = workModelArrayList;
    }

    @Override    public int getCount() {
        return workModelArrayList.size();
    }

    @Override    public WorkModel getItem(int i) {
        return workModelArrayList.get(i);
    }

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

    @Override    public View getView(final int i, View view, ViewGroup viewGroup) {
        final ViewHolder viewHolder;
        if (view == null) {
            final LayoutInflater inflater = ((Activity) context).getLayoutInflater();
            view = inflater.inflate(R.layout.row_worker, viewGroup, false);
            viewHolder = new ViewHolder(view);
            view.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) view.getTag();
        }
        final WorkModel workModel = workModelArrayList.get(i);

        removeTextChangedListener(viewHolder);
        viewHolder.edtName.setText(workModel.getWorkerName());
        addTextChangedListener(viewHolder, i);

        return view;
    }

    private class ViewHolder {
        private EditText edtName;
        private MyTextWatcher myTextWatcher;

        ViewHolder(final View view) {
            edtName = (EditText) view.findViewById(R.id.row_worker_edit_name);
        }

        public EditText getProductQuantity() {
            return edtName;
        }

        public MyTextWatcher getTextChangedListener() {
            return myTextWatcher;
        }

        public void setTextChangedListener(MyTextWatcher textChangedListener) {
            this.myTextWatcher = textChangedListener;
        }

    }

    private class MyTextWatcher implements TextWatcher {
        private int pos;

        public MyTextWatcher(final int pos) {
            this.pos = pos;
        }

        @Override        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override        public void afterTextChanged(Editable editable) {
            workModelArrayList.get(pos).setWorkerName(editable.toString());
        }
    }

    private void removeTextChangedListener(ViewHolder viewHolder) {
        final MyTextWatcher textChangedListener = viewHolder.getTextChangedListener();
        final EditText edtValue = viewHolder.getProductQuantity();
        edtValue.removeTextChangedListener(textChangedListener);
    }

    private void addTextChangedListener(ViewHolder viewHolder, int position) {
        final MyTextWatcher textChangedListener = new MyTextWatcher(position);
        final EditText edtValue = viewHolder.getProductQuantity();
        edtValue.addTextChangedListener(textChangedListener);
        viewHolder.setTextChangedListener(textChangedListener);
    }

}

Model Class : 

public class WorkModel {

    private int workerId;
    private String workerName;

    public int getWorkerId() {
        return workerId;
    }

    public void setWorkerId(int workerId) {
        this.workerId = workerId;
    }

    public String getWorkerName() {
        return workerName;
    }

    public void setWorkerName(String workerName) {
        this.workerName = workerName;
    }
}

Activity Class :  

 
public class MainActivity extends AppCompatActivity {

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ListView lv = (ListView) findViewById(R.id.activity_main_lv);
        final ArrayList<WorkModel> workModelList = new ArrayList<>();

        for(int i = 0 ; i < 1000; i++){
            workModelList.add(new WorkModel());
        }

        final WorkListAdapter workListAdapter = new WorkListAdapter(this, workModelList);
        lv.setAdapter(workListAdapter);

    }
}
