Question

因此，在用户选择联系后，我将按照以下代码获取联系人数量：

public void openSmsWindowToContactNumber(Intent data, String smsBody) {

        // Get the URI that points to the selected contact
        Uri contactUri = data.getData();
        // We only need the NUMBER column, because there will be only one row in the result
        String[] projection = {Phone.NUMBER};

        // Perform the query on the contact to get the NUMBER column
        // We don't need a selection or sort order (there's only one result for the given URI)
        // CAUTION: The query() method should be called from a separate thread to avoid blocking
        // your app's UI thread. (For simplicity of the sample, this code doesn't do that.)
        // Consider using CursorLoader to perform the query.
        Cursor cursor = BaseActivity.this.getContentResolver()
                .query(contactUri, projection, null, null, null);

        cursor.moveToFirst();
        int column = cursor.getColumnIndex(Phone.NUMBER);
        String number = cursor.getString(column);

        Intent smsIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("smsto:" + number));
        smsIntent.putExtra("sms_body", smsBody);
        startActivity(smsIntent);
    }

在设备上运行时，联想A916（A916）操作系统：Android 4.4我收到此错误：

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=75502, result=-1, data=Intent { dat=content://com.android.contacts/data/240 flg=0x1 }} to activity {com.sm.proba/com.sm.proba.ClassPage}: java.lang.NullPointerException

游标将为null，找不到联系人数据。我开始用以下方式选择联系意图：

Intent pickContactIntent = new Intent(Intent.ACTION_PICK, Uri.parse("content://contacts"));
pickContactIntent.setType(Phone.CONTENT_TYPE);
startActivityForResult(pickContactIntent, REQUEST_CODE_PICK_CONTACTS);

有人知道如何解决这个问题吗？
