这篇博客讲述了在Android中如何经过一天的资料查找和测试，成功实现读取特定联系人数据的方法。首先通过跳转到联系人列表，然后在onActivityResult方法中处理返回结果，最终在华为和小米设备上得到验证。

android读取特定联系人是真的烦，网上代码一大堆，但是拿过来又不好使，无奈，只有自己一点一点弄了(找资料+测试 = 一天时间)。
首先需要跳转到联系人列表：

        Intent intent = new Intent(Intent.ACTION_PICK);
        intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
        if (intent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(intent, PEOPLE_REQUEST_CODE);
        }

接下来重新onActivityResult方法

if(resultCode == RESULT_OK){
            if(requestCode == PEOPLE_REQUEST_CODE){
                if(null == data){
                    return;
                }
                //获得选取的联系人信息
                Uri mUri = data.getData();
                String [] contact=getPhoneContacts(mUri);
                if(contact != null){
                    Map<String,String> map = new HashMap<String,String>();
                    map.put(contact[0],contact[1]);
                    contacts.add(map);
                    adapter.notifyDataSetChanged();
                }

            }
        }

private String[] getPhoneContacts(Uri uri){
        String [] contacts = new String[2];
        String[] projectionNumber = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
        Cursor cursorNumber = getContentResolver().query(uri, projectionNumber, null, null, null);
        Log.e(TAG, "Cursor: "+cursorNumber.getPosition() );
        // If the cursor returned is valid, get the phone number
        if (cursorNumber != null && cursorNumber.moveToFirst()) {
            int numberIndex = cursorNumber.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            Log.e(TAG, "getPhoneContacts: numberIndex"+"-->"+numberIndex );
            String number = cursorNumber.getString(numberIndex);
            // Do something with the phone number
            number = number.replaceAll("-","");
            number = number.replaceAll(" ","");
            Log.e(TAG, "getPhoneContacts: number"+"-->"+number );
            contacts[1] = number;
            cursorNumber.close();
        }else{
            cursorNumber.close();
            showMissingPermissionDialog();
            return null;
        }

        String[] projectionName = new String[]{ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME};
        Cursor cursorName = getContentResolver().query(uri, projectionName, null, null, null);
        if (cursorName != null && cursorName.moveToFirst()) {
            int nameIndex = cursorName.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
            Log.e(TAG, "getPhoneContacts: nameIndex"+"-->"+nameIndex );
            String name = cursorName.getString(nameIndex);
            Log.e(TAG, "getPhoneContacts: name"+"-->"+name );
            // Do something with the phone name
            contacts[0] = name;
            cursorName.close();
        }else{
            cursorName.close();
            showMissingPermissionDialog();
            return null;
        }

        return contacts;
    }
/**

    private void showMissingPermissionDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle(R.string.notifyTitle);
        builder.setMessage(R.string.notifyContactMsg);

        // 拒绝, 退出应用
        builder.setNegativeButton(R.string.cancel,
                new DialogInterface.OnClickListener() {
                    @Override
