我在使用简单适配器将图像设置为 ListView 时遇到了一点问题。我使用 sqlite 数据库中的 ID 从 sdcard 获取图像,因此 sqlite 语句有效,图像在 sdcard 上,但如果我尝试在我的 ListView 中设置它们,它会给我一个输出:
resolveUri failed on bad bitmap uri: android.graphics.Bitmap@40566318
在 LogCat 上。这是我用来执行此操作的代码:
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);
最佳答案
我用这个修复了它:path = Environment.getExternalStorageDirectory() + "/MyApp/MediaCollection/"+ objectId + ".png";
