在我的应用程序中，我使用.txt文件来保存地理位置和字符串，因此我可以删除一行，而不是从.txt中删除一堆换行符。所以我把它放在测试中只是为了保存数据，保存得很好，但是当我加载数据时，我得到一个内存不足的位图，它是96x96解码文件，这对我来说没有意义。
这是logcat：

我注意到的一件事是，每次堆消息出现时，只有5％到6％可用，所以我启动模拟器擦除数据，这是一回事。这是一个api 17模拟器，当应用程序与文本文件一起运行时，它运行得很好。
接下来我要尝试的是;即使我打开数据库阅读我正在使用：
db = dbHelper.getWritableDatabase();
所以我要把它改成getReadableDatabase
这不是一个很大的改变，而是在这个错误之前的活动中，它完成了一切。在TextWatcher的画布上，有两个位图来回发送。我认为它只需要内存2位图320X480与.txt文件运行良好。
非常感谢任何建议，谢谢你的时间。
Cursor cursor;
db.read();
cursor = db.getAllEntries();
boolean go = cursor.moveToFirst();
while(cursor.isAfterLast() != true){
Drawable imagebig = null;
Bitmap photobig = null;
int lat = cursor.getInt(MyDBAdapter.LATITUDE_COLUMN);
int lng = cursor.getInt(MyDBAdapter.LONGITUDE_COLUMN);
GeoPoint recall = new GeoPoint(lat,lng);
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Gone");
file = new File(file.getPath(),"Thumbs");
String string = cursor.getString(MyDBAdapter.FILE_COLUMN);
File file1 = new File(file.getPath() + File.separator + "thumb" + string);
Uri uri = Uri.fromFile(file1);
if(file1.exists()){
//photobig = BitmapFactory.decodeFile(file1.getAbsolutePath());
uri = Uri.fromFile(file1);
try {
photobig = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
db.close();
cursor.close();
答案 0 :(得分：3)
你有一个无限的while循环。游标需要先进。
添加cursor.moveToNext（）;到你的while循环。
答案 1 :(得分：0)
并改变这个
while(cursor.isAfterLast() != true){
表示
while(!cursor.isAfterLast()){
