我想改变应用程序的主题，问题是当我重新创建（）活动时，应用程序变白，直到它内存不足。 当我删除Sqlite DB处理程序时，它运行完美。 如果你能指出正确的方向那就太好了！
if(bundle.getBoolean("anss")==true){
SharedPreferences.Editor editor= settings.edit();
editor.putString("theme","zebra");
editor.commit();//Intent i = new Intent(this, MainActivity.class);
// i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// this.finish();
// this.startActivity(i);
// myDBHandler.close();
recreate();
}
感谢。
编辑：我默认在sql中添加一些数据，只要sqlite数据库是空的，现在有问题，但如果用户添加了应用程序再次崩溃的东西，我认为它是因为我使用recreate（）或finish（ ）。12-28 22:36:33.091 17463-17463/thehuntest.com.beta E/art: Throwing OutOfMemoryError "Failed to allocate a 28 byte allocation with 4 free bytes and 4B until OOM" (recursive case)

答案 0 :(得分：0)
也许你有开光标。 使用下一个结构：
Cursor cursor = null;
try {
cursor = getCursor();
if (cursor.moveToFirst) {
//your commands
}
} finally {
if (cursor != null) {
cursor.close();
}
}
