Question

在Android中拨打电话时，我无法显示联系人姓名。

这是我的代码：

String callTo = "9999900000";
String callername="xxx";    
Intent callIntent = new Intent(Intent.ACTION_CALL);                 
callIntent.setData(Uri.parse("tel:"+ callTo));                  
String srvname=Context.TELEPHONY_SERVICE;    
TelephonyManager tm=(TelephonyManager)getSystemService(srvname);                     
startActivity(callIntent);

Answer 1

为此您需要创建一个广播接收器，并在 OnReceive 方法中检查OUTGOING CALL状态，然后从中获取呼叫者号码，然后创建另一种方法来检查该联系人是否存在您是否可以移动该方法中的联系号码。

以下是来电者姓名broadcastReceiver

的代码

package com.example.user.caller;

import android.content.BroadcastReceiver;
import android.content.ContentResolver;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;


import android.telephony.TelephonyManager;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver {

    String phoneNumber;
    String name;



    @Override
    public void onReceive(Context context, Intent intent) {
        String action=intent.getAction();
        Bundle extras=intent.getExtras();
        if(action.equals("android.intent.action.PHONE_STATE")){
            String state=extras.getString(TelephonyManager.EXTRA_STATE);
            if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){

                String incomingnumber=extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                String msg = "";
                //  String person = getCname(context,msg);

                String names = getContactDisplayNameByNumber(incomingnumber,context);

                //  Toast.makeText(context,"Caller Name"+person,Toast.LENGTH_SHORT).show();

                displayToast(context,"phone is ringing"+incomingnumber+ "calling you mr."+names);

                Intent intent1  = new Intent(context,
                        MainActivity.class);

    private void displayToast(Context context,String msg){

        }
        return name;
    }

    public String getContactDisplayNameByNumber(String number,Context context) {
        Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
        name = "Incoming call from";

        ContentResolver contentResolver = context.getContentResolver();
        Cursor contactLookup = contentResolver.query(uri, null, null, null, null);

        try {
            if (contactLookup != null && contactLookup.getCount() > 0) {
                contactLookup.moveToNext();
                name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
                // this.id =
                // contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.CONTACT_ID));
                // String contactId =
                // contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
            }else{
                name = "Unknown number";
            }
        } finally {

                contactLookup.close();
            }
        }

        return name;
    }


}
