我在使用SimpleAdapter将图片设置到ListView时遇到了一些问题。我从SD卡中获取图片,并使用SQLite数据库中的ID进行匹配,SQLite语句已经正常运行,图片也存在于SD卡中,但是当我尝试将它们设置到我的ListView时,输出结果会出错:
resolveUri failed on bad bitmap uri: android.graphics.Bitmap@40566318
在LogCat上查看日志。这是我使用的代码:
String sqlite2 = "SELECT objectId FROM collectionmedias WHERE collectionId="+collId+" AND mediaType="+fronImage;
Cursor bg = userDbHelper.executeSQLQuery(sqlite2);
if (bg.getCount() == 0) {
Log.i("", "No Image file");
bg.close();
} else if (bg.getCount() > 0) {
for (bg.move(0); bg.moveToNext(); bg.isAfterLast()) {
objectId = Integer.parseInt(bg.getString(bg.getColumnIndex("objectId")));
Log.i("","objectId : "+objectId);
path = Environment.getExternalStorageDirectory()
+ "/.MyApp/MediaCollection/" + objectId + ".png";
Log.v("","path: "+path);
}
}
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[2*1024];
Bitmap ops = BitmapFactory.decodeFile(path, options);
hm = new HashMap<String, Object>();
hm.put(IMAGE, ops);
hm.put(TITLE, text);
hm.put(CARDS_COUNT, cardsCount +" MyApp");
items.add(hm);
}
final SimpleAdapter adapter = new SimpleAdapter(this, items, R.layout.main_listview,
new String[]{TITLE, CARDS_COUNT, IMAGE}, new int[]{ R.id.main_name, R.id.main_info, R.id.main_img});
listView.setAdapter(adapter);
