我是Android世界的新蜜蜂。我有一个listview,里面有checkbox和EditText。当我在列表视图中显示记录时,我将选中复选框并在editText字段中输入文本。我会在同一行中做很多行。我有一个名为Save的按钮。使用这个我想用新添加的文本和复选框值保存listview的详细信息。单击保存按钮时,我不知道如何获取值。请指导我。这是代码。
main.xml中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/TextView01" android:layout_height="wrap_content"
android:text="List of items" android:textStyle="normal|bold"
android:gravity="center_vertical|center_horizontal"
android:layout_width="fill_parent"></TextView>
<ListView android:id="@+id/ListView01" android:layout_height="wrap_content"
android:layout_width="fill_parent">
</ListView>
<Button android:text="Save" android:id="@+id/btnSave"
android:layout_width="wrap_content" android:layout_height="wrap_content">
</Button>
</LinearLayout>
listview.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:gravity="left|center"
android:layout_width="wrap_content" android:paddingBottom="5px"
android:paddingTop="5px" android:paddingLeft="5px">
<TextView android:id="@+id/TextView01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:gravity="center"
android:textColor="#FFFF00" android:text="hi"></TextView>
<TextView android:text="hello" android:id="@+id/TextView02"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_marginLeft="10px" android:textColor="#0099CC"></TextView>
<EditText android:id="@+id/txtbox" android:layout_width="120px"
android:layout_height="wrap_content" android:textSize="12sp"
android:layout_x="211px" android:layout_y="13px">
</EditText>
<CheckBox android:id="@+id/chkbox1" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

试试这个,
btnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
for (int i = 0; i <l1.getCount() ; i++) {
View vListSortOrder;
vListSortOrder=l1.getChildAt(i);
try{
EditText edit=(EditText)vListSortOrder.findViewById(R.id.share_comment_edit);
String temp=edit.getText().toString();
}
}
});
同样为CheckBox创建一个对象并获取其状态。简单。

我知道edittext使用以下内容:
holder.txt = ((EditText) convertView.findViewById(R.id.txtbox).getEditableText()).toString();
