com.android.inputmethod.latin 中的 ANR 原因：输入调度超时

【中文标题】com.android.inputmethod.latin 中的 ANR 原因：输入调度超时【英文标题】：ANR in com.android.inputmethod.latin Reason: Input dispatching timed out 【发布时间】：2019-03-19 19:18:00 【问题描述】：我在本地数据库中有近 6,000 条数据。在一个片段上，我从该记录中得到一个字段，即“EAN 代码”，几乎是 6,000。现在我将这些数据设置在一个 ArrayList 中。之后，我在 AutoTextCompleteView 的适配器中设置了 ArrayList。当我搜索 AutoTextCompleteView 时，它会挂起我的页面。我的片段没有响应。我很困惑是由于大量数据还是什么。请帮忙。
代码：
if (getCodeType.equals("art"))
modelProductCodeList = databaseHelper.getProductsArticleCode();
for (int k = 0; k < modelProductCodeList.size(); k++)
productCodeList.add(modelProductCodeList.get(k).getArticle_code());
actSearchCode.setAdapter(null);
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1, productCodeList);
actSearchCode.setAdapter(adapter);
rgGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
@Override
public void onCheckedChanged(RadioGroup radioGroup, int i)
if (i == R.id.rdbArticleCode)
actSearchCode.setText("");
getCodeType = "art";
modelProductCodeList = databaseHelper.getProductsArticleCode();
databaseHelper.close();
productCodeList.clear();
for (int k = 0; k < modelProductCodeList.size(); k++)
productCodeList.add(modelProductCodeList.get(k).getArticle_code());
actSearchCode.setAdapter(null);
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1, productCodeList);
actSearchCode.setAdapter(adapter);
else if (i == R.id.rdbEANCode)
actSearchCode.setText("871128");
getCodeType = "ean";
modelProductCodeList = databaseHelper.getProductsEANCode();
databaseHelper.close();
productCodeList.clear();
for (int k = 0; k < modelProductCodeList.size(); k++)
productCodeList.add(modelProductCodeList.get(k).getEan_code());
actSearchCode.setAdapter(null);
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1, productCodeList);
actSearchCode.setAdapter(adapter);
);
actSearchCode.setThreshold(3);
actSearchCode.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l)
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(actSearchCode.getApplicationWindowToken(), 0);
Fragment fragment = new ProductDetailFragment();
FragmentManager fragmentManager = getFragmentManager(); // this is basically context of the class
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Bundle bundle = new Bundle();
bundle.putString("product_art", (String) adapterView.getItemAtPosition(i));
bundle.putString("source_type", getCodeType);
fragment.setArguments(bundle);
fragmentTransaction.replace(R.id.frame, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
);

【问题讨论】：
【参考方案1】：你应该在初始化所有变量后在 onCreate 中添加这些
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1, productCodeList);
actSearchCode.setAdapter(adapter);
而且您不需要每次都设置一个新的适配器，您只需设置一次适配器，然后使用 productCodeList.clear() 并添加所有对象然后调用 adapter.notifyDatasetChanged()
【讨论】：
请把片段的全部代码贴出来，这会有所帮助 已添加请查看【参考方案2】：最好使用不同的ArrayList而不是单个ArrayList
HashMap<String,ArrayList> mapSearchList= new LinkedHashMap<>();
如果第一个字符从您开始设置为适配器，则在 ontextchange 侦听器中
setadapter(context,mapSearchList.get("a")) // etc
并设置阈值
