主要活动：
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragment_container);
if (fragment == null) {
fragment = new RecyclerFragment();
fm.beginTransaction().add(R.id.fragment_container, fragment).commit();
}
}
}
Recycler片段，容器适配器和视图。添加使用适配器的updateUI方法后，应用程序崩溃。
public class RecyclerFragment extends Fragment {
private RecyclerView mRecyclerView;
private FrogAdapter mAdapter;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.recycler, container, false);
mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
updateUI();
return view;
}
private void updateUI() {
Pond pond = Pond.get(getActivity());
List<Frog> frogs = pond.getFrogs();
if (mAdapter == null) {
mAdapter = new FrogAdapter(frogs);
mRecyclerView.setAdapter(mAdapter);
} else {
mAdapter.notifyDataSetChanged();
}
}
private class FrogHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView mName;
private TextView mWord;
public FrogHolder(LayoutInflater inflater, ViewGroup parent) {
super(inflater.inflate(R.layout.item, parent, false));
itemView.setOnClickListener(this);
mName = (TextView) itemView.findViewById(R.id.name);
mWord = (TextView) itemView.findViewById(R.id.word);
}
@Override
public void onClick(View v) {
}
}
private class FrogAdapter extends RecyclerView.Adapter<FrogHolder>{
private List<Frog> mFrogs;
public FrogAdapter(List<Frog> frogs) {
mFrogs = frogs;
}
@Override
public FrogHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
return new FrogHolder(layoutInflater, parent);
}
@Override
public void onBindViewHolder(FrogHolder holder, int position) {
Frog frog = mFrogs.get(position);
holder.mName.setText(frog.getName());
holder.mWord.setText(frog.getWord());
}
@Override
public int getItemCount() {
return mFrogs.size();
}
}
}
此类构成要显示的回收站视图的列表：
public class Pond {
public class Frog {
private String mName;
private String mWord;
public String getName() {
return mName;
}
public void setName(String name) {
mName = name;
}
public String getWord() {
return mWord;
}
public void setWord(String word) {
mWord = word;
}
}
private static Pond sPond;
private List<Frog> mFrogs;
public static Pond get(Context context) {
if (sPond == null) {
sPond = new Pond(context);
}
return sPond;
}
private Pond(Context context) {
mFrogs = new ArrayList<>();
for (int i = 0; i < 100; i++) {
Frog frog = new Frog();
frog.setName("Frog #" + i);
frog.setWord("qqq");
mFrogs.add(frog);
}
}
public List<Frog> getFrogs() {
return mFrogs;
}
}

答案 0 :(得分：2)
当android开始处理位图时导致此问题。 主要原因是内存空间不足，垃圾收集器也无法释放一些空间。
对于这种情况，您有两种解决方案：
转到您的清单文件并添加
机器人：largeHeap =＆＃34;真＆＃34;
机器人：硬件加速=＆＃34;假＆＃34;
内部应用程序标记，例如
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:largeHeap="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
