Question

我正在尝试设计一个Android系统，其中紧急呼叫可以放在我想要的数量上。我有一个患者界面，在我的界面中，我已经给医生拨了一个紧急呼叫按钮，如果他们开始感觉不舒服，那么只需点击一下按钮，就可以给医生打电话。

public void callDoc(View v)
    {
        Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("myNumber"));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_NO_USER_ACTION);
        startActivity(intent);
    }

这是我到目前为止所尝试的。是否可以在localhost上测试？我没有得到理想的结果。这是我的logcat。

Answer 1

tel

String number = "23454568678";
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" +number));
    startActivity(intent);

使用权限

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

Answer 2

您是否已获得CALL_PHONE权限？如果没有，则在清单文件中添加以下持久性

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

其次，Uri.parse("myNumber")的参数应该以“tel：”前缀开头，所以如果数字是1234，那么调用Uri.parse应该是Uri.parse("tel: " + "myNumber")
