android 跳转到系统通讯录

跳转到系统的通信录列表，并读取联系人电话

需要权限

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

6.0之后需要动态申请权限

int readStoragePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS);

if (readStoragePermission != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_READ_CONTACT);
} else {
    Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    startActivityForResult(intent, GET_CONTACT);

}

//请求权限回调

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case REQUEST_READ_CONTACT://读取手机联系人权限
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission Granted

		Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    		startActivityForResult(intent, GET_CONTACT);
            } else {
                // Permission Denied
            }
            break;
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

//获取点击选中的联系人回调

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {

    case GET_CONTACT: 

	if (resultCode == RESULT_OK) {

	     Uri uri = data.getData();

	     getPhone(uri);

	}

         break;			

}

private void getPhone(Uri uri) {
        if (uri != null) {
            Cursor c = getContentResolver().query(uri, null, null, null, null);
