问题描述
@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button = (Button) findViewById(R.id.buttonQuary); name = (TextView) findViewById(R.id.tv_name); phone = (TextView) findViewById(R.id.tv); button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) { Uri uri = Uri.parse('content://contacts/people'); Intent intent = new Intent(Intent.ACTION_PICK, uri); startActivityForResult(intent, 0);} });}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) {case 0: if (data == null) {return; } //处理返回的data,获取选择的联系人信息 Uri uri = data.getData(); getPhoneContacts(uri); name.setText(myname); phone.setText(phonenumber); break; } super.onActivityResult(requestCode, resultCode, data);}private String[] getPhoneContacts(Uri uri) { String[] contact = new String[2]; //得到ContentResolver对象 ContentResolver cr = getContentResolver(); //取得电话本中开始一项的光标 Cursor cursor = cr.query(uri, null, null, null, null); if (cursor != null) {cursor.moveToFirst();//取得联系人姓名int nameFieldColumnIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);myname = cursor.getString(nameFieldColumnIndex);/*//取得电话号码String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + '=' + ContactId, null, null);if (phone != null) { phone.moveToFirst(); phonenumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));}phone.close();*/cursor.close(); } else {return null; } return contact;}
以上是代码， 这样是可以运行的，能获取到名字，我注释掉的部分是获取电话的，无法获取到所以注释掉，求解决啊
问题解答
回答1：代码是没有问题，不过这段代码需要添加权限<uses-permission android:name='android.permission.READ_CONTACTS' />不知你的问题是返回null还是直接报权限问题错误；
