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;
}
}
}
