问题:

I m a new bee to Android world. I have a listview which has checkbox and EditText in it. When I display records in the listview, I will check the checkbox and enter text in the editText field. I will do in many rows in the same. I have a button called Save. Using this I want to save the details of listview with newly added text and checkbox value. I do not know how to get the values when i click the save button. Please guide me. Here is the code.

main.xml:

    <?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>

}

回答1:

Try this,

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();

        }
      }
    });

Similarly create a object for your CheckBox and get its state. Simple.

I know that edittext uses the following:

holder.txt = ((EditText) convertView.findViewById(R.id.txtbox).getEditableText()).toString();
