Ich habe versucht, die Werte von ListView-Elementen als "mylistview.getItemAtPosition (position) .toString()" abzurufen, aber es gibt nur die Position des Elements zurück, auf das ich klicke.Wie kann ich Elemente aus einem Listview-Objekt abrufen, das sowohl String (Name) als auch Integer (Kontakte) enthält?

Mein MainActivity.java:

public class MainActivity extends AppCompatActivity{ 
    RelativeLayout rl1; 
    Button b1,b2,b3,b4,b5,b6,b7,b8,b9,b0,bhash,bStar,del,call; 
    EditText editText; 
    Intent phoneIntent,callIntent; 
    getContacts.MyAdapter myAdapter; 
    ListView lv; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     rl1=(RelativeLayout) findViewById(R.id.relativeLayout); 
     rl1.setVisibility(View.GONE); 

     editText = (EditText)findViewById(R.id.textView); 
     editText.setShowSoftInputOnFocus(false); 
     b1 = (Button)findViewById(R.id.button); 
     b2 = (Button)findViewById(R.id.button2); 
     b3 = (Button)findViewById(R.id.button3); 
     b4 = (Button)findViewById(R.id.button4); 
     b5 = (Button)findViewById(R.id.button5); 
     b6 = (Button)findViewById(R.id.button6); 
     b7 = (Button)findViewById(R.id.button7); 
     b8 = (Button)findViewById(R.id.button8); 
     b9 = (Button)findViewById(R.id.button9); 
     b0 = (Button)findViewById(R.id.button0); 
     bhash = (Button)findViewById(R.id.buttonHash); 
     bStar = (Button)findViewById(R.id.buttonStar); 
     call = (Button) findViewById(R.id.buttonCall); 
     del = (Button)findViewById(R.id.buttonDel); 

     getContacts.getAllContacts(this.getContentResolver()); 
    myAdapter = new getContacts.MyAdapter(getApplicationContext()); 

     final List<Object> name2 = new ArrayList<>(); 
     final ListView lv= (ListView) findViewById(R.id.lv); 
     lv.setAdapter(myAdapter); 
     lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {

Mein getContacts.java:

     while (phones.moveToNext())

      String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      System.out.println(".................."+phoneNumber); 
      name1.add(name); 
      phno1.add(phoneNumber); 
     } 

     phones.close(); 
    } 

    static class MyAdapter extends BaseAdapter 
    { 
     private SparseBooleanArray mCheckStates; 
     LayoutInflater mInflater; 
     TextView tv1,tv; 
     MyAdapter(Context ctx) 
     { 
      mCheckStates = new SparseBooleanArray(name1.size()); 
      //mInflater = (LayoutInflater)Display.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      mInflater = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     } 
     @Override 
     public int getCount() { 
      // TODO Auto-generated method stub 
      return name1.size(); 
     } 

     @Override 
     public Object getItem(int position) { 
      // TODO Auto-generated method stub 
      return position; 
     } 

     @Override 
     public long getItemId(int position) { 
      // TODO Auto-generated method stub 

      return 0; 
     } 

     @Override 
     public View getView(final int position, View convertView, ViewGroup parent) { 
      // TODO Auto-generated method stub 
      View vi=convertView; 
      if(convertView==null) 
       vi = mInflater.inflate(R.layout.row, null); 
      TextView tv= (TextView) vi.findViewById(R.id.textView1); 
      tv1= (TextView) vi.findViewById(R.id.textView2); 
      tv.setText(name1.get(position)); 
      // tv1.setText(phno1.get(position)); 


      return vi; 
     } 

    } 

} 

Kann mir jemand bitte helfen Sie die Daten aus dem ausgewählten Listeneintrag zu bekommen?

könnten Sie versuchen, in Ihrem Adapter machen Methoden, etwa wie folgt:

public String getName(int position) { 
    return name1.get(position); 
} 

public String getPhoneNumber(int position) { 
    return phno1.get(position); 
} 

Da Sie sagen, dass Sie den Index erhalten, rufen Sie diese Methoden in Ihrem mainactivity auf Ihrem Adapter-Objekt. Dies funktioniert nur, wenn die Positionen der Elemente in Ihrer Arraylist übereinstimmen.

Ich schlage auch vor, Objekte zu verwenden, um Ihre Daten zu speichern, schauen Sie hier für weitere Informationen: https://www.raywenderlich.com/124438/android-listview-tutorial
