为我的公司做一些研发。我们正在尝试使listView包含一个imageview，以及listview中每个条目的两个编辑框。
<?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"
android:isScrollContainer="true"
android:focusableInTouchMode="false"
android:focusable="false">
<ImageView android:id="@+id/imgView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxWidth="100dp"
android:maxHeight="100dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText android:id="@+id/img_title"
android:hint="Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="150dp"/>
<EditText android:id="@+id/img_desc"
android:hint="Description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="150dp"/>
</LinearLayout>
</LinearLayout>
这是我试图用于列表视图中的项目的布局文件。在我们的ImageAdapter的getView（扩展了ArrayAdapter）中，
我试图使用LayoutInflater来膨胀xml，然后将其存储到ViewGroup中。我找到了ViewViewByID（）来获取xml中的imageView，并设置我们想要的imageView的属性。
如果我们继续膨胀该xml文件，则所有ID都将相同。这是我们的问题。
如果我们删除带有
上下文菜单，它实际上删除了
不正确的一个。测试显示
这主要是添加的最后一个，
但不总是。
EditText不响应键盘输入。有时，它们存储一些数据，通常总是“ bbb”。
我们还有其他问题，但是在解决了这些更严重的错误之后，我们会回发。
public View getView(int position, View convertView, ViewGroup parent)
{
final ImageView imageView;
//InputStream is = null;
final Context mContext = super.getContext();
final AdapterItem item = super.getItem(position);
final Uri imageUri = item.getUri();
ViewGroup viewGroup = null;
try
{
//-- If the view has not been created yet.
if (convertView == null)
{
/*
* Build the ImageView from the URI with some custom
* view settings.
*/
viewGroup = (ViewGroup) LayoutInflater.from(mContext).inflate(R.layout.mediauploadobject, null);
imageView = (ImageView) viewGroup.findViewById(R.id.imgView);
//imageView.setLayoutParams(new GridView.LayoutParams(IMAGE_WIDTH, IMAGE_HEIGHT));
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setPadding(IMAGE_PADDING_LEFT, IMAGE_PADDING_TOP,
IMAGE_PADDING_RIGHT, IMAGE_PADDING_BOTTOM);
imageView.setDrawingCacheEnabled(true);
imageView.setClickable(true);
imageView.setFocusable(true);
imageView.setFocusableInTouchMode(true);
imageView.setSaveEnabled(false);
//the following two lines are required for the menu to popUp
imageView.setOnLongClickListener(new LongClickListener());
imageView.setOnCreateContextMenuListener(new LongClickMenu());
imageView.setOnClickListener(new ShortClickListener());
//the following two lines are required to put a boarder around the images
imageView.setOnTouchListener(new PictureOnTouchListener());
imageView.setOnFocusChangeListener(new PictureOnFocusChangeListener());
//-- Keep a reference to the ImageView by tagging it.
imageView.setTag(imageUri);
}else
{
//-- R-E-C-Y-C-L-E recycle!
viewGroup = (ViewGroup) convertView;
imageView = (ImageView) viewGroup.findViewById(R.id.imgView);
}
//-- Lazy load the images so the user doesn't have to wait for all of the querying non-sense
// that happens behind the scenes.
imageView.setImageResource(android.R.drawable.gallery_thumb);
imageView.post(new ImageLoader(imageUri, imageView));
//-- Be VERY careful when changing this code. Due to heap size issues,
// the size of the bitmap image MUST be modified with the
// provided BitmapFactory.Options or the program will
// crash often and frequent.
//post
//-- AJG 7/1/2010 added this assignment so we aren't always setting these preferences every
// iteration
convertView = viewGroup;
}catch(Throwable t)
{
Log.e(TAG, t.toString());
return null;
}finally
{
//try{if(is != null)is.close();}catch(Exception squish){}
}
return viewGroup;
}
最佳答案
默认情况下，子视图在列表视图中无法集中显示。这是为了防止轨迹球/非触摸导航行为异常。这可能就是为什么您的edittexts不响应输入的原因。确保正在调用ListView.setItemsCanFocus（true）方法。
