java - 打开联系人后如何直接调用电话

Question

当我点击按钮选择联系人并选择联系人时不调用该号码时的问题，我想在选择号码时直接调用电话

buttoncontact = findViewById(R.id.choosecontact);


public void choosecontact1 (View view){

     Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

   intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
    startActivityForResult(intent, PICK_CONTACT)


}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    String call = buttoncontact.getText().toString();


    if ((requestCode == 1) && (resultCode == RESULT_OK)) {
        Cursor cursor = null;
        try {
            Uri uri = data.getData();
            cursor = getContentResolver().query(uri, new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER }, null, null, null);
            if (cursor != null && cursor.moveToNext()) {
                String phone = cursor.getString(0);

//该代码的问题

                Intent intent = new Intent(Intent.ACTION_CALL);
                intent.setData(Uri.parse(String.valueOf("tel:" + CONTENT_TYPE)));

//我想打开电话联系人并直接调用

                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.


                    return;

                }

                startActivity(intent);

            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

什么是“CONTENT_TYPE”？不应该是你刚刚得到的电话字符串吗？

intent.setData(Uri.parse("tel:" + phone));
