android - 单击按钮时如何在android中获取复选框，带有ListView值的EditText？

Question

我是 Android 世界的新蜜蜂。我有一个 ListView ，其中包含复选框和 EditText。当我在 ListView 中显示记录时，我将选中复选框并在 editText 字段中输入文本。我会在很多行中做同样的事情。我有一个名为保存的按钮。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。

主.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>

            Toast.makeText(getBaseContext(), "EditText Value, checkbox value and other values", Toast.LENGTH_SHORT).show();

        }
    });

private static final String[] country = { "item1", "item2", "item3",
        "item4", "item5", "item6" };
private static final String[] curr = { "1", "2", "3", "4", "5", "6" };

}

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();

        }
      }
    });

类似地为您的 CheckBox 创建一个对象并获取其状态。简单的。
