我有一個ListView中的Checkbox和EditText以及Textview。它從列表中獲取文本視圖的值。複選框將被動態檢查。以同樣的方式EditText也可以動態輸入。現在我的問題是，當我在編輯文本中輸入文本後滾動列表視圖（上下）時，我無法獲得鍵入的值。我也檢查複選框。但是使用這個位置，我設置它是正確的。我無法知道如何正確設置EditText值到列表中。請幫幫我。這裏是我的代碼：如何在listview中添加EditText並在所有行中動態獲取其值？
的main.xml：（發射升空主XML）
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/my_list"
android:layout_width="fill_parent"
android:layout_height="250px" />
<Button
android:text="Save"
android:id="@+id/btnSave"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
row.xml：（ListView的行）
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:textSize="30sp"/>
<CheckBox
android:id="@+id/check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<EditText
android:text=""
android:id="@+id/txtAddress"
android:layout_width="150px"

</LinearLayout>
Model.Java：（這是POJO類）
package com.checkboxlistview;
public class Model {
private String name;
private boolean selected;
private String address;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public void setName(String name) {
this.name = name;
}
public Model(String name) {
this.name = name;
}
public String getName() {
return name;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
}
MyAdapter.Java：（這是用於使用所述轉換器和保持器保持在列表視圖中的視圖）
package com.checkboxlistview;

public class MyAdapter extends ArrayAdapter<Model> implements TextWatcher {
private final List<Model> list;
private final Activity context;
int listPosititon;
public MyAdapter(Activity context, List<Model> list) {
super(context, R.layout.row, list);
this.context = context;
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected CheckBox checkbox;
protected EditText address;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
listPosititon = position;

viewHolder.checkbox
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
int getPosition = (Integer) buttonView.getTag();
//Here we get the position that we have set for the checkbox using setTag.
list.get(getPosition).setSelected(
buttonView.isChecked());
// Set the value of checkbox to maintain its state.
}
});
viewHolder.address.addTextChangedListener(this);
convertView.setTag(viewHolder);
convertView.setTag(R.id.label, viewHolder.text);
convertView.setTag(R.id.check, viewHolder.checkbox);
convertView.setTag(R.id.txtAddress, viewHolder.address);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.checkbox.setTag(position); // This line is important.
viewHolder.text.setText(list.get(position).getName());
viewHolder.checkbox.setChecked(list.get(position).isSelected());
if (list.get(position).getAddress() != null) {
viewHolder.address.setText(list.get(position).getAddress() + "");
} else {
viewHolder.address.setText("");
}
return convertView;
}
@Override
public void afterTextChanged(Editable s) {
list.get(listPosititon).setAddress(s.toString());
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {

有一個在代碼沒有錯誤。它運行良好。我可以保持複選框的位置並顯示在相同的位置，即使我上下滾動。但我無法正確設置EditText值。請幫助我。 在此先感謝。
嗨Munish卡普爾，感謝您的答覆。這個對我有用。我使用AddTextChangedListener從EditText獲取文本。但是使用你的示例我知道，我們需要使用setOnFocusChangeListener。非常感謝。我試了兩天。 – Mathew
您的歡迎.. :) –
嗨Munish卡普爾，我有這個複選框和列表視圖編輯文本中的另一個問題。當我點擊一個複選框時，它必須關注特定的行EditText。如何做到這一點。請幫助我。 – Mathew
