フラグメントタブ内のボタン

Question

3つのタブがあります。タブの1つがコンテンツリゾルバを使用して通話ログを読み取る必要があります。レイアウト内に4つのボタンを配置し、これらの通話記録を「欠落」、「着信」、「発信」、「すべての通話」で別々に表示します。 「不在着信」ボタンをクリックすると、そのタブのlistViewに不在着信のみが表示されます。どのようにこれらのボタンを使って表示するのか、このコードをどうやって置くのですか？

public class TabFragment2 extends Fragment { 

    Button b1,b2,b3,b4; 
    private Toolbar supportActionBar; 
    private FragmentManager supportFragmentManager; 

    ArrayList<HashMap<String, String>> Calllist1 = new ArrayList<>(); 
    ListView callListView; 
    ArrayAdapter arrayAdapter; 


    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.activity_call, container, false); 
     callListView = (ListView) view.findViewById(R.id.listView1); 
     Button b1 = (Button) view.findViewById(R.id.button); 
     /* arrayAdapter = new ArrayAdapter<String>(getActivity().getApplicationContext(), android.R.layout.simple_list_item_1, Calllist1); 
     callListView.setAdapter(arrayAdapter);*/ 
     getCallDetails(); 
     b1.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

      } 
     }); 
     return view; 



    } 

    private void getCallDetails() { 

     String strOrder = CallLog.Calls.DATE + " DESC"; 
     Uri callUri = Uri.parse("content://call_log/calls"); 
     ContentResolver ca = getActivity().getContentResolver(); 
     Cursor managedCursor = getActivity().getContentResolver().query(callUri, null, null, null, strOrder); 
     int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
     int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE); 
     int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
     int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 

     while (managedCursor != null && managedCursor.moveToNext()) { 
      String phNum = managedCursor.getString(number); 
      String callTypeCode = managedCursor.getString(type); 
      String strcallDate = managedCursor.getString(date); 
      SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yy HH:mm"); 
      long seconds = managedCursor.getLong(date); 
      String dateString = formatter.format(new Date(seconds)); 
      String callDuration = managedCursor.getString(duration); 
      String callType = null; 

     HashMap<String, String> callMap = new HashMap<String, String>(); 
      callMap.put("NUMBER", phNum); 
      callMap.put("CALL", callTypeCode); 
      callMap.put("DATE", dateString); 
      callMap.put("DURATION", callDuration); 
      Calllist1.add(callMap); 

      int callcode = Integer.parseInt(callTypeCode); 
      switch (callcode) { 
       case CallLog.Calls.OUTGOING_TYPE: 
        callType = "Outgoing"; 
        break; 
       case CallLog.Calls.INCOMING_TYPE: 
        callType = "Incoming"; 
        break; 
       case CallLog.Calls.MISSED_TYPE: 
        callType = "Missed"; 
        break; 

      } 

     } 
     managedCursor.close(); 
     callListView.setAdapter(new CallAdapter(getActivity().getApplicationContext(), android.R.layout.simple_list_item_1, Calllist1)); 

    } 

}

私はあなたのコードをいくつか変更しました。してみてください。

public class TabFragment2 extends Fragment { 

    Button b1,b2,b3,b4; 
    private Toolbar supportActionBar; 
    private FragmentManager supportFragmentManager; 

    ArrayList<HashMap<String, String>> callListDisplay = new ArrayList<>(); 
    ArrayList<HashMap<String, String>> callMissed = new ArrayList<>(); 
    ArrayList<HashMap<String, String>> callOutgoing = new ArrayList<>(); 
    ArrayList<HashMap<String, String>> callIncoming = new ArrayList<>(); 
    ListView callListView; 
    CallAdapter arrayAdapter; 


    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.activity_call, container, false); 
     callListView = (ListView) view.findViewById(R.id.listView1); 
     Button b1 = (Button) view.findViewById(R.id.button); 
     arrayAdapter= new CallAdapter(getActivity(), android.R.layout.simple_list_item_1, callListDisplay) 
     callListView.setAdapter(arrayAdapter); 
     getCallDetails(); 
     // to load initial values 
     loadValues(0); 
     b1.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       loadValues(0); 
      } 
     }); 
     b2.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
    loadValues(1); 
      } 
     }); 
     b3.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       loadValues(2); 
      } 
     }); 
     return view; 
    } 

    private void loadValues(int type){ 
     if(type==0){ 
      callListDisplay.clear(); 
      callListDisplay.addAll(callMissed); 
      arrayAdapter.notifyDataSetChanged(); 
     }else if(type==1){ 
      callListDisplay.clear(); 
      callListDisplay.addAll(callOutgoing); 
      arrayAdapter.notifyDataSetChanged(); 
     }else if(type==2){ 
      callListDisplay.clear(); 
      callListDisplay.addAll(callIncoming); 
      arrayAdapter.notifyDataSetChanged(); 
     } 
    } 

    private void getCallDetails() { 

     String strOrder = CallLog.Calls.DATE + " DESC"; 
     Uri callUri = Uri.parse("content://call_log/calls"); 
     ContentResolver ca = getActivity().getContentResolver(); 
     Cursor managedCursor = getActivity().getContentResolver().query(callUri, null, null, null, strOrder); 
     int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
     int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE); 
     int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
     int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 

     while (managedCursor != null && managedCursor.moveToNext()) { 
      String phNum = managedCursor.getString(number); 
      String callTypeCode = managedCursor.getString(type); 
      String strcallDate = managedCursor.getString(date); 
      SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yy HH:mm"); 
      long seconds = managedCursor.getLong(date); 
      String dateString = formatter.format(new Date(seconds)); 
      String callDuration = managedCursor.getString(duration); 
      String callType = null; 

     HashMap<String, String> callMap = new HashMap<String, String>(); 
      callMap.put("NUMBER", phNum); 
      callMap.put("CALL", callTypeCode); 
      callMap.put("DATE", dateString); 
      callMap.put("DURATION", callDuration); 


      int callcode = Integer.parseInt(callTypeCode); 
      switch (callcode) { 
       case CallLog.Calls.OUTGOING_TYPE: 
        callType = "Outgoing"; 
        callOutgoing.add(callMap); 
        break; 
       case CallLog.Calls.INCOMING_TYPE: 
        callType = "Incoming"; 
        callIncoming.add(callMap); 
        break; 
       case CallLog.Calls.MISSED_TYPE: 
        callType = "Missed"; 
        callMissed.add(callMap); 
        break; 

      } 

     } 
     managedCursor.close(); 


    } 

    } 

ベースアダプターを拡張することにより、独自のアダプタークラスを使用することを常にお勧めします。これにより、私たちは視点をより詳細に制御することができます。
