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uriprivate 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"?>
<LinearLayoutxmlns: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"><ListViewandroid: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;@Overrideprotected 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();}}@Overridepublic 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() {@Overridepublic 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 {@Overridepublic int getCount() {return phoneDtos.size();}@Overridepublic Object getItem(int position) {return phoneDtos.get(position);}@Overridepublic long getItemId(int position) {return position;}@SuppressLint("NewApi")@Overridepublic 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.最后不要忘记添加权限, 在AndroidManifest.xml中加入,如果没有添加动态申请权限的话,可以去设置里面手动打开

<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.CALL_PHONE" />

6.好了这样的话就已经完成了
