使用intentfilter从XML获取数据的问题
我需要，当我点击XML文件，将数据从文件传递到应用程序…如果我传递文件的路径静态它工作…但如果我使用intent filter所以我动态传递数据它不起作用…我告诉你两个代码：
没有意图filter：
File file = new File(Environment.getExternalStorageDirectory() .getAbsolutePath() + "/ordinazioni/26:Maggio:2017-15:02:40 PM.xml"); FileInputStream is = new FileInputStream(file); . . .
有意图filter：
Intent intentt = getActivity().getIntent(); String intenttt=intentt.getData().toString(); System.out.println("INTENT:"+intenttt); //File filee = new File(intenttt); File file = new File(Environment.getExternalStorageDirectory() .getAbsolutePath() +intenttt); System.out.println("FILE:"+file); FileInputStream is = new FileInputStream(file); . . .
谁能帮我？
在OnCreate：
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { int a=0; String status=""; boolean statuss = false; /* File file = new File(Environment.getExternalStorageDirectory() .getAbsolutePath() + "/ordinazioni/26:Maggio:2017-15:02:40 PM.xml");*/ Intent intentt = getActivity().getIntent(); String intenttt=intentt.getData().toString(); System.out.println("INTENT:"+intenttt); //File filee = new File(intenttt); File file = new File(Environment.getExternalStorageDirectory() .getAbsolutePath() +intenttt); System.out.println("FILE:"+file); FileInputStream is = new FileInputStream(file); DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); Document doc = dBuilder.parse(is); Element element = doc.getDocumentElement(); element.normalize(); NodeList nList = doc.getElementsByTagName("checkboxes_pizza"); for (int i = 0; i < nList.getLength(); i++) { Node node = nList.item(i); if (node.getNodeType() == Node.ELEMENT_NODE) { Element element2 = (Element) node; //tv1.setText(tv1.getText()+"\nName : " + getValue("name", element2)+"\n"); String id = getValue("id", element2); a = Integer.parseInt(id); status = getValue("status", element2); statuss= Boolean.parseBoolean(status); System.out.println("XML:" + a); hm.add(a); } } } catch (Exception e) { e.printStackTrace(); } } private static String getValue(String tag, Element element) { NodeList nodeList = element.getElementsByTagName(tag).item(0).getChildNodes(); Node node = nodeList.item(0); return node.getNodeValue(); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the custom_spinner_items for this fragment //super.onDestroy(); SharedPreferences settings = getContext().getSharedPreferences("states", Context.MODE_PRIVATE); SharedPreferences.Editor editor = settings.edit(); editor.clear(); editor.commit(); ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_list2, container, false); ck=(CheckBox)rootView.findViewById(R.id.chk_box); //lv = (ListView)getView().findViewById(R.id.listview); //lv = (ListView) rootView.findViewById(R.id.listview); //ListAdapter listAdapter = new MyListAdapter(getContext()); //lv.setAdapter(listAdapter); context = getActivity(); mInstance = getActivity(); btnLogout = (Button) rootView.findViewById(R.id.btnLogout); return rootView; } @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); lv = (ListView)getView().findViewById(R.id.listview); //ck=(CheckBox)getView().findViewById(R.id.chk_box); displayPlanetList(); } private void displayPlanetList() { planetList = new ArrayList(); planetList.add(new Planet(0, "Margherita", "6", "€", "(pomodoro e mozzarella)")); planetList.add(new Planet(1,"Diavola", "7","€","(pomodoro,mozzarella e salsiccia piccante)")); planetList.add(new Planet(2,"Bufalina", "5","€","(pomodoro e mozzarella di bufala)")); planetList.add(new Planet(3, "Marinara", "5", "€", "(pomodoro)")); planetList.add(new Planet(4,"Viennese", "4", "€", "(pomodoro,mozzarella e wrustel)")); plAdapter = new PlanetAdapter(planetList, getContext(),imageId,hm) { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { String pero=""; int la=0; int pos = lv.getPositionForView(buttonView); System.out.println("POS:"+pos); if (pos != ListView.INVALID_POSITION) { Planet p = planetList.get(pos); p.setSelected(isChecked); Toast.makeText( getActivity(), "Clicked on Pizza: " + la + ". State: is " + isChecked, Toast.LENGTH_SHORT).show(); } } }; lv.setAdapter(plAdapter); }
自定义适配器：
public abstract class PlanetAdapter extends ArrayAdapter implements CompoundButton.OnCheckedChangeListener, View.OnClickListener { private List planetList; private Context context ; ArrayList objects;

试着用这个：
传递数据时，filepath是包含动态文件路径的字符串：
intent.putExtra("filename",filepath);
得到它：
String intenttt=intentt.getExtras().getString("filename");
