Question

我的表单如下图所示，我想通过单击添加按钮并为此使用ContentProviderOperation来添加新联系人

我该怎么做？非常感谢！！

这是我的onlick方法

btnAdd.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            edtName = (EditText) findViewById(R.id.edtName);
            edtPhone = (EditText) findViewById(R.id.edtPhone);
            edtEmail = (EditText) findViewById(R.id.edtEmail);

        }
    });

添加联系人之前，您必须先对清单文件启用权限。

Android清单：

 <uses-permission android:name="android.permission.WRITE_CONTACTS" />

添加权限后。我创建了一个添加联系人的活动。

AddPhoneContactActivity.java文件

import android.content.ContentUris;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;

import android.widget.Spinner;
import android.widget.Toast;

import com.test.example.R;

public class AddPhoneContactActivity extends AppCompatActivity {

private EditText displayNameEditor;

private EditText phoneNumberEditor;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_addcontact);

    setTitle("dev2qa.com - Android Add Phone Contact Example.");

    displayNameEditor = (EditText)findViewById(R.id.add_phone_contact_display_name);

    phoneNumberEditor = (EditText)findViewById(R.id.add_phone_contact_number);

    // Initialize phone type dropdown spinner.
    final Spinner phoneTypeSpinner = (Spinner)findViewById(R.id.add_phone_contact_type);
    String phoneTypeArr[] = {"Mobile", "Home", "Work"};
    ArrayAdapter<String> phoneTypeSpinnerAdaptor = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, phoneTypeArr);
    phoneTypeSpinner.setAdapter(phoneTypeSpinnerAdaptor);

    // Click this button to save user input phone contact info.
    Button savePhoneContactButton = (Button)findViewById(R.id.add_phone_contact_save_button);
    savePhoneContactButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Get android phone contact content provider uri.
            //Uri addContactsUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
            // Below uri can avoid java.lang.UnsupportedOperationException: URI: content://com.android.contacts/data/phones error.
            Uri addContactsUri = ContactsContract.Data.CONTENT_URI;

            // Add an empty contact and get the generated id.
            long rowContactId = getRawContactId();

            // Add contact name data.
            String displayName = displayNameEditor.getText().toString();
            insertContactDisplayName(addContactsUri, rowContactId, displayName);

            // Add contact phone data.
            String phoneNumber = phoneNumberEditor.getText().toString();
            String phoneTypeStr = (String)phoneTypeSpinner.getSelectedItem();
            insertContactPhoneNumber(addContactsUri, rowContactId, phoneNumber, phoneTypeStr);

            Toast.makeText(getApplicationContext(),"New contact has been added, go back to previous page to see it in contacts list." , Toast.LENGTH_LONG).show();

            finish();
        }
    });
}

// This method will only insert an empty data to RawContacts.CONTENT_URI
// The purpose is to get a system generated raw contact id.
private long getRawContactId()
{
    // Inser an empty contact.
    ContentValues contentValues = new ContentValues();
    Uri rawContactUri = getContentResolver().insert(ContactsContract.RawContacts.CONTENT_URI, contentValues);

    long ret = ContentUris.parseId(rawContactUri);
    return ret;

    contentValues.put(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, displayName);

    getContentResolver().insert(addContactsUri, contentValues);

}

private void insertContactPhoneNumber(Uri addContactsUri, long rawContactId, String phoneNumber, String phoneTypeStr)
{
    // Create a ContentValues object.
    ContentValues contentValues = new ContentValues();

    contentValues.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId);

    // Put phone number value.

    // Calculate phone type by user selection.
    int phoneContactType = ContactsContract.CommonDataKinds.Phone.TYPE_HOME;

    if("home".equalsIgnoreCase(phoneTypeStr))
    {
        phoneContactType = ContactsContract.CommonDataKinds.Phone.TYPE_HOME;
    }else if("mobile".equalsIgnoreCase(phoneTypeStr))
    {
        phoneContactType = ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE;
    }else if("work".equalsIgnoreCase(phoneTypeStr))
    {

    }
    // Put phone type value.
    contentValues.put(ContactsContract.CommonDataKinds.Phone.TYPE, phoneContactType);

    // Insert new contact data into phone contact list.
    getContentResolver().insert(addContactsUri, contentValues);

}

// ListPhoneContactsActivity use this method to start this activity.
public static void start(Context context)
{
    Intent intent = new Intent(context, AddPhoneContactActivity.class);
    context.startActivity(intent);
}
