Question

我的想法是，如果有人点击列表中的某个联系人，他们会直接拨打，但我无法实施。代码没有错误我唯一的问题是当我点击我只设法Toast“拷贝号”

    String[] mobileArray = {"   NAMES       LOCATION & CODE        CONTACTS ",

        super.onCreate(savedInstanceState);
        setContentView(R.layout.contact);

        ArrayAdapter adapter = new ArrayAdapter<String>(this, R.layout.activity_contact, mobileArray);

        ListView listView = (ListView) findViewById(R.id.mobile_list);
        listView.setAdapter(adapter);
    }
    public void call_id(View view){

        Toast.makeText(getApplicationContext()," copy number ",Toast.LENGTH_LONG).show();

    }


    public void compose_email(View v){
        String myEmail[]={"john@balloonventures.com"};
        Intent sendMail = new Intent(Intent.ACTION_SEND);
        sendMail.putExtra(Intent.EXTRA_EMAIL,myEmail);
        sendMail.putExtra(Intent.EXTRA_SUBJECT,"(Host_home)emergency");
        sendMail.setType("plain/text");
        //incase you have to add something else put here
        sendMail.putExtra(Intent.EXTRA_TEXT,"Your phone:+2547");
   ``     startActivity(sendMail);


    }
    }

Answer 1

您的代码不完整，您没有为ListView设置项目单击侦听器。

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Phone_number"));
            startActivity(intent);
        }
    });

另外，不要忘记为Manifest.xml添加适当的权限

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

Answer 2

//where is your calling code , you didnit implement?



Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Phone_number"));
startActivity(intent);

//manifest


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

//put java code in  call_id
