SimpleCursorAdapter与ImageView的和的TextView [英] SimpleCursorAdapter with ImageView and TextView

问题描述

您可以用 ImageView的布局和的TextView 的行中的 SimpleCursorAdapter 有一个ListView？

can you have a layout with an imageview and textview for a row in a SimpleCursorAdapter with a listview?

这将是布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">

<ImageView
    android:id="@+id/icon"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<TextView
    android:id="@+id/bowler_txt"
    android:paddingLeft="25dp"
    android:textSize="30dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Bowler"
    android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

可以在在SimpleCursorAdapter做一个列表视图？当我需要的图像在ListView我一直使用的自定义arrayadapter，但从来没有与游标。

can it be done in SimpleCursorAdapter with a listview? when I needed images in a listview I always used a custom arrayadapter but never with a cursor.

我将如何设置形象，如果这是可以做到？

How would I set the image if it can be done?

推荐答案

在视图绑定是的ImageView 并没有现有的 ViewBinder 相关 SimpleCursorAdapter.bindView（）电话 setViewImage（ImageView的，字符串）。 默认情况下，该值将被视为一个的图像资源的。如果该值不能用作图像资源，则该值被用​​作图像乌里的。

When the view to bind is an ImageView and there is no existing ViewBinder associated SimpleCursorAdapter.bindView() calls setViewImage(ImageView, String). By default, the value will be treated as an image resource. If the value cannot be used as an image resource, the value is used as an image Uri.

如果您需要在其他方面来筛选需要从你的数据库中检索的值 ViewBinder 添加到 ListAdapter 如下：

If you need to filter in other ways the value retrieved from the database you need a ViewBinder to add to the ListAdapter as follow:

listAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder(){
   /** Binds the Cursor column defined by the specified index to the specified view */
   public boolean setViewValue(View view, Cursor cursor, int columnIndex){
       if(view.getId() == R.id.your_image_view_id){
           //...
           ((ImageView)view).setImageDrawable(...);
           return true; //true because the data was bound to the view
       }
       return false;
   }
});
