我一直在寻找我的Android应用程序上的“内存泄漏”问题的解决方案,但是,这是事情:
我正在viewpager中加载一个片段,这个片段有一个Gridview和一个Adapter(ArrayAdapter),它创建gridview的每个项目,这些项目有一个图像和一些文本(我使用Universal Image Loader)来加载图像。)
当我改变设备方向时,我会收到很多内存泄漏。
这些更改中没有一项有效,我仍然会收到内存泄漏,欢迎任何帮助!

public class MoviesFragment extends Fragment {
public MoviesFragment() {
}
final String TAG = MoviesFragment.class.toString();
ExpandableHeightGridView movieGridView;
MovieAdapter mMovieAdapter;
ArrayList<Movie> movies;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle args = getArguments();
movies = args.getParcelableArrayList("movies");
mMovieAdapter = new MovieAdapter(getActivity().getApplicationContext(), movies);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.fragment_movies, container, false);
movieGridView = (ExpandableHeightGridView) rootView.findViewById(R.id.gridview_movies);
if (movies != null) {
movieGridView.setAdapter(mMovieAdapter);
movieGridView.setExpanded(true);
movieGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
EventBus.getDefault().post(
new EventSelectedEvent((Movie) parent.getItemAtPosition(position)));
}
});
} else {
movieGridView.setExpanded(false);
}
return rootView;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
public class MovieAdapter extends ArrayAdapter<Movie> {
Context context;
public MovieAdapter(Context context, List<Movie> movies) {
super(context, 0, movies);
this.context = context.getApplicationContext();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Movie movie = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = LayoutInflater.from(getContext().getApplicationContext()).inflate(R.layout.layout_card_movies, parent, false);
}
// Lookup view for data population
TextView movieName = (TextView) convertView.findViewById(R.id.card_movie_text);
//Load square image
Image squareImg = movie.getSquareImage();
if (null != squareImg) {
ImageLoader iLoader = ImageLoaderHandler.getImageLoader(TandasApplication.getInstance());
iLoader.displayImage(squareImg.getLink(),
(ImageView) convertView.findViewById(R.id.card_movie_image));
}
//Title
movieName.setText(movie.getTitle());
//Rating
LinearLayout ratingContainer = (LinearLayout) convertView.findViewById(R.id.ratingMovieMainView);
double rating = movie.getRating();
UIUtils.buildRatingStars(rating, ratingContainer, context);
// Return the completed view to render on screen
return convertView;
}
}
答案 0 :(得分:0)
如果没有太多信息,我认为你正在坚持你的片段引用。
使用adb shell命令dumpsys
进行测试adb shell dumpsys activity <package_name>
adb shell dumpsys meminfo <package_name>
导航各种片段并在每次导航其中之后运行此片段。 Meminfo将告诉您应用程序持有多少活动。活动为你打破了一切。
如果您发布一些日志或代码,我可以帮助您更好。
