안드로이드 스튜디오 SQL 데이터베이스 표시 및 여러 내가 목록보기에서 mg의 SQL 데이터베이스에 연락처를 표시 할 것이

Question

로 선택하고 내가 여러 연락처를 선택하고 다음 활동에서의 전자 메일 주소를 복사 할 수 있습니다

여기 내 SQL 데이터베이스에 연락처를 표시하는 코드입니다하지만 난을 선택 여러 날 수 있도록 실 거예요 ..

좋아, 여기에 각 데이터 항목에 대한 checkbox을 추가하는 사용자 정의 어댑터와 ListView 아주 기본적인있어 .

대체 어댑터 checkboxes을 확인하여 간단한 어댑터에서 수행 할 수없는 adpater에서 어떻게 조작 할 수 있는지에 대한 기본 아이디어를 제공합니다.

활동의 클래스, Listview (각 행) 및 마지막으로 사용자 정의 어댑터의 각 항목에 대한 두 번째 레이아웃 (XML) 인 Listview를 비롯한 주요 활동의 레이아웃 (XML) . ListView의 ListView에

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/activity_main" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context="mjt.listviewwithcutsomadapter.MainActivity"> 

    <ListView 
     android:id="@+id/mylistview" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 
    </ListView> 
</RelativeLayout> 

mylistview_entry 각 항목 (행)에 대한 레이아웃

MainActivity

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.widget.ListView; 

import java.util.ArrayList; 

public class MainActivity extends AppCompatActivity { 

    private ListView mylistview; 
    private ArrayList<String> mylist = new ArrayList<>(); 
    private MyListViewCustomAdapter myListViewCustomAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mylist.add("Fred"); 
     mylist.add("Bert"); 
     mylist.add("Harry"); 

     mylistview = (ListView) this.findViewById(R.id.mylistview); 
     myListViewCustomAdapter = new MyListViewCustomAdapter(this,R.layout.activity_main,mylist); 
     mylistview.setAdapter(myListViewCustomAdapter); 

    } 
} 

activity_main 레이아웃. CheckBox에 유의하십시오. 이것이 이루어집니다 ListView의의 사용자 정의 어댑터 기본적 입/로우 레이아웃 행이 처리 될 때마다 데이터를 결합

import android.app.Activity; 
import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.CheckBox; 
import android.widget.TextView; 

import java.util.ArrayList; 


public class MyListViewCustomAdapter extends ArrayAdapter<String> { 

    private Context context; 
    private ArrayList<String> mylist; 
    private TextView tv_name; 
    private CheckBox tv_chkbox; 

    public MyListViewCustomAdapter(Activity context, int layout, ArrayList<String> mylist) { 
     super(context, layout, mylist); 
     this.context = context; 
     this.mylist = mylist; 
    } 

    @Override 
    public View getView(int position, View view, ViewGroup parent) { 

     if(view == null) { 
      view = LayoutInflater.from(context).inflate(R.layout.mylistview_entry,parent,false); 
     } 

     tv_name = (TextView) view.findViewById(R.id.mylistviewentry_name); 
     tv_chkbox = (CheckBox) view.findViewById(R.id.mylistviewentry_checkbox); 

     tv_name.setText(mylist.get(position)); 
     if(position % 2 == 0) { 
      tv_chkbox.setChecked(true); 
     } else { 
      tv_chkbox.setChecked(false); 
     } 
     return view; 
    } 
} 

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="horizontal" 
    android:layout_width="match_parent"
