ContactsContract.CommonDataKinds.Phone.CONTACT_ID 返回的值为null

intent.setType("vnd.android.cursor.item/phone");
改成
intent.setType("vnd.android.cursor.item/phone_v2");
然后去掉重复创建的cursor。
代码如下:
public class SysAction extends Activity { final int PICK_CONTACT = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sys_action); Button bn = (Button)findViewById(R.id.bn); bn.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent(); intent.setAction(Intent.ACTION_GET_CONTENT); intent.setType("vnd.android.cursor.item/phone_v2"); startActivityForResult(intent,PICK_CONTACT); } }); } @TargetApi(Build.VERSION_CODES.HONEYCOMB) @SuppressLint("NewApi") public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch(requestCode) { case(PICK_CONTACT): if(resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); CursorLoader cursorLoader = new CursorLoader(this, contactData, null, null, null, null); Cursor cursor =cursorLoader.loadInBackground(); if (cursor.moveToFirst()) { String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); EditText show = (EditText)findViewById(R.id.show); show.setText(name); EditText phone = (EditText)findViewById(R.id.phone); phone.setText(phoneNumber); } cursor.close(); } break; } } }
