您好目前我正在Android Studio上使用FragmentPagerAdapter切換片段，每個片段都使用根片段，因此當我使用一個片段時，它可以很好地工作，但是當我想實現第二個時，它給了我下面的錯誤;Android - 沒有找到片段，更改片段的視圖
java.lang.IllegalArgumentException: No view found for id 0x7f0c00ae (net.beardboy.aarcapp:id/root_frame_graphs) for fragment GraphsFragment{d178606 #0 id=0x7f0c00ae}
我片段之間交換使用getSupportFragmentManager（），正如我所說的它工作得很好，我第一次使用，但隨後它給了我錯誤。這是我的代碼：
public class MainActivity extends AppCompatActivity implements ReportsAdapter.ReportCallBacks {
ProgressDialog progressDialogReports;
ProgressDialog progressDialogGraphs;
ProgressDialog progressDialogSettings;
DrawerLayout drawerLayout;
ViewPager viewPager;
FragmentPagerAdapter fragmentPagerAdapter;
Toolbar toolbar;
User currentUser;
SessionStateManager sessionStateManager;
RequestQueue requestQueue;
ReportsFragments reportsFragments;
GraphsFragment graphsFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sessionStateManager = new SessionStateManager(this);
currentUser = new User();
currentUser = sessionStateManager.getCurrentUser();
requestQueue = Volley.newRequestQueue(this);
graphsFragment = new GraphsFragment();
toolbar = (Toolbar) findViewById(R.id.toolbar_main);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabBarLayout);
viewPager = (ViewPager) findViewById(R.id.viewPager);
setSupportActionBar(toolbar);
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
fragmentPagerAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) {
private static final int FRAGMENT_COUNT = 3;
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
try {
getReportsdata();
} catch (JSONException e) {
e.printStackTrace();
}
return new RootFragmentReports();
case 1:
getGraphsdata();
return new RootFragmentGraphs();
case 2:
return new RootFragmentSettings();
}
return null;
}
@Override
public int getCount() {
return FRAGMENT_COUNT;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Reportes";
case 1:
return "Graficas";
case 2:
return "Pagos";
default:
return null;
}
}
};
viewPager.setOffscreenPageLimit(3);
viewPager.setAdapter(fragmentPagerAdapter);
tabLayout.setupWithViewPager(viewPager);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
invalidateOptionsMenu();
}
@Override
public void onPageSelected(int position) {
invalidateOptionsMenu();
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
public void getReportsdata() throws JSONException {
progressDialogReports = ProgressDialog.show(MainActivity.this, getString(R.string.please_wait), getString(R.string.downloading_data), true, false);
JSONObject jsonUser = new JSONObject();
JSONObject jsonMain = new JSONObject();
jsonUser.put(JSONKeys.KEY_ACCESS_TOKEN, currentUser.getAccess_token());
jsonUser.put(JSONKeys.KEY_CLIENTE_ID, currentUser.getCilenteId());
jsonUser.put(JSONKeys.KEY_NAME, currentUser.getName());
jsonUser.put(JSONKeys.KEY_EMAIL, currentUser.getEmail());
jsonMain.put(JSONKeys.KEY_AARC_USER, jsonUser);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, JSONKeys.URL_REPORTES_POR_CLIENTE, jsonMain, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
progressDialogReports.dismiss();
try {
ArrayList<JSONReport> jsonReports = (ArrayList<JSONReport>) JSONParser.parseJSONReport(response);
replaceFragment(jsonReports);
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
progressDialogReports.dismiss();
Log.i("errr", error.toString());
DialogUtil.createSimpleDialog(MainActivity.this, getString(R.string.error_downloading_data), error.toString()).show();
}
});
int socketTimeout = 180000;//3 minutes - change to what you want
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
jsonObjectRequest.setRetryPolicy(policy);
requestQueue.add(jsonObjectRequest);
}
public void getGraphsdata() {
ArrayList<Graph> graphArrayList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
Graph graficas = new Graph();
graficas.setAnalisis(i);
graficas.setSucursal("descripcion" + i);
graphArrayList.add(graficas);
}
ArrayList<Entry> entries = new ArrayList<>();
entries.add(new Entry(2f, 0));
entries.add(new Entry(4f, 1));
entries.add(new Entry(3f, 2));
entries.add(new Entry(4f, 3));
LineDataSet dataset = new LineDataSet(entries, "Fecha");
ArrayList<String> labels = new ArrayList<String>();
labels.add("January");
labels.add("February");
labels.add("January");
labels.add("February");
replaceFragmentGraph(graphArrayList);
}
private void replaceFragment(ArrayList<JSONReport> jsonReports) {
reportsFragments = new ReportsFragments();
ReportsAdapter reportsAdapter;
reportsAdapter = new ReportsAdapter(MainActivity.this, jsonReports);
reportsAdapter.setReportAdapterCallBacks(MainActivity.this);
reportsFragments.setComplaintsAdapter(reportsAdapter);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.root_frame_actividades, reportsFragments)
.commit();
}
private void replaceFragmentGraph(ArrayList<Graph> datos) {
graphsFragment = new GraphsFragment();
//Bundle bundle=new Bundle();
//bundle.putParcelable("datos", (Parcelable) datos);
//graphsFragment.setArguments(bundle);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.root_frame_graphsa, graphsFragment)
//.addToBackStack(null)
.commit();
}
@Override
public void OnReportCallBacks(JSONReport jsonReport) {
Intent intent = new Intent(this, ReportsDetailActivity.class);
intent.putExtra(JSONKeys.KEY_FOLIOB, jsonReport.getFoliob());
startActivity(intent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_acitivity_main, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Intent intent = new Intent(this, SettingsActivity.class);
startActivity(intent);
return super.onOptionsItemSelected(item);
}
}
錯誤開始時，我在getSupportFragmentManager（）的添加GraphsFragment出現，我仔細檢查了佈局的ID是正確的參數等，但由於在錯誤的ID 0x7f0c00ae後來在同一行上再次出現同一個id，原諒我的英文不好。謝謝你們。
編輯 我GraphsFragment類
public class GraphsFragment extends Fragment {
LineChart chart;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootview = inflater.inflate(R.layout.fragment_graphs, container, false);
chart = (LineChart) rootview.findViewById(R.id.linechart);
return rootview;
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//code
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
}
}
fragments_graphs.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

RootFragmentGraphs類
public class RootFragmentGraphs extends Fragment{
private static final String TAG = "RootFragmentGraphs";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_root_fragment_graficas, container, false);
return view;
}
}
fragment_root_fragment_graficas.xml

</FrameLayout>
請你能添加代碼爲GraphsFragment – Omar
代碼添加@Omar – miguelacio
能否請您包括代碼爲您活動的onCreate，然後還包括XML你在哪裏宣佈你的碎片？ – ishmaelMakitla
