Android 获取手机联系人列表

老规矩先上效果图:

在Android6.0以后我们需要手动去获取权限,我在程序里已经加入,其他权限可以参考Android 6.0权限管理以及动态申请,

友善提醒:不要用于非法用途哟

下面直接贴代码

1.先写一个实体类,来放名字和号码

public class PhoneDto {
    private String name;        //联系人姓名
    private String telPhone;    //电话号码


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getTelPhone() {
        return telPhone;
    }

    public void setTelPhone(String telPhone) {
        this.telPhone = telPhone;
    }

    public PhoneDto() {
    }

    public PhoneDto(String name, String telPhone) {
        this.name = name;
        this.telPhone = telPhone;
    }
}

2.写我们获取联系人的工具类

public class PhoneUtil {

    // 号码
    public final static String NUM = ContactsContract.CommonDataKinds.Phone.NUMBER;
    // 联系人姓名
    public final static String NAME = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME;

    //上下文对象
    private Context context;
    //联系人提供者的uri
    private Uri phoneUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

    public PhoneUtil(Context context){
        this.context = context;
    }

    //获取所有联系人
    public List<PhoneDto> getPhone(){
        List<PhoneDto> phoneDtos = new ArrayList<>();
        ContentResolver cr = context.getContentResolver();
        Cursor cursor = cr.query(phoneUri,new String[]{NUM,NAME},null,null,null);
        while (cursor.moveToNext()){
            PhoneDto phoneDto = new PhoneDto(cursor.getString(cursor.getColumnIndex(NAME)),cursor.getString(cursor.getColumnIndex(NUM)));
            phoneDtos.add(phoneDto);
        }
        return phoneDtos;
    }
}

3.接下来贴主页面布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.test.content.MainActivity">

    <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/lv_main_list"></ListView>

</LinearLayout>

4.该贴主Activity代码了

public class MainActivity extends AppCompatActivity {


    private List<PhoneDto> phoneDtos;
    private ListView lv_main_list;

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

    /**
     * 检查权限
     */
    private void check() {
        //判断是否有权限
        if(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_CONTACTS)
                != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.READ_CONTACTS},201);
        }else{
            initViews();
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(requestCode==201){
            initViews();
        }else{
            return;
        }
    }

    private void initViews() {
        PhoneUtil phoneUtil = new PhoneUtil(this);
        phoneDtos = phoneUtil.getPhone();
        lv_main_list = (ListView) findViewById(R.id.lv_main_list);
        MyAdapter myAdapter = new MyAdapter();
        lv_main_list.setAdapter(myAdapter);
        //给listview增加点击事件
        /*lv_main_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //拨打电话
                Intent intent = new Intent();
                intent.setAction("android.intent.action.CALL");
                intent.addCategory(Intent.CATEGORY_DEFAULT);
                intent.setData(Uri.parse("tel:"+phoneDtos.get(position).getTelPhone()));
                startActivity(intent);
            }
        });*/
    }
    //自定义适配器
    private class MyAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            return phoneDtos.size();
        }

        @Override
        public Object getItem(int position) {
            return phoneDtos.get(position);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @SuppressLint("NewApi")
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            PhoneDto phoneDto = phoneDtos.get(position);
            LinearLayout linearLayout = new LinearLayout(MainActivity.this);
            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.weight = 1;
            TextView tv_name = new TextView(MainActivity.this);
            tv_name.setId(View.generateViewId());
            tv_name.setLayoutParams(layoutParams);
            tv_name.setText(phoneDto.getName());
            TextView tv_num = new TextView(MainActivity.this);
            tv_num.setId(View.generateViewId());
            tv_num.setLayoutParams(layoutParams);
            tv_num.setText(phoneDto.getTelPhone());
            linearLayout.addView(tv_name);
            linearLayout.addView(tv_num);
            return linearLayout;
        }
    }
}

5.好了这样的话就已经完成了
