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 getPhone(){ List 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 4.该贴主Activity代码了 public class MainActivity extends AppCompatActivity { private List 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.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 6.好了这样的话就已经完成了
