Java 如何使用Intent.ACTION\u Call选择通话号码？

我试图在点击按钮时提供两个号码的选项，以便直接拨打该号码，但当我选择其中一个号码时，它将进入拨号器屏幕，但其中写入了“Ljava.lang.CharSequence”，并且不支持弹出带有消息服务的对话框

这是我的密码：-

phone.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                final CharSequence numbers[] = new CharSequence[] {"02212345678","+14356789809"};

                AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
                builder.setTitle("Select number to call");
                builder.setItems(numbers, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                        Intent callIntent = new Intent(Intent.ACTION_CALL);
                        String call = "tel:" +numbers;
                        callIntent.setData(Uri.parse(call));
                        startActivity(callIntent);


                    }
                });
                builder.show();


            }
        });

这是一个完整的代码，用于提供号码选择并通过单击按钮调用所选号码。我希望这对其他议员也有帮助

phone.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                final CharSequence numbers[] = new CharSequence[] {"+1xxxxxxxxx","+1xxxxxxxxxx"};

                AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
                builder.setTitle("Select number to call");
                builder.setItems(numbers, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                        Intent callIntent = new Intent(Intent.ACTION_CALL);
                        String call = "tel:" +numbers[which];
                        callIntent.setData(Uri.parse(call));
                        startActivity(callIntent);

                        // the user clicked on colors[which]
                    }
                });
                builder.show();


            }
        });

已在清单文件中添加了调用权限。@Dilip是的，我已授予权限“”，问题在于数组，我猜好像我正在传递一个数字，它工作正常。您做错了。如果你想做出选择，你应该做出选择。您只是使用了一个错误类型的参数。您传递的整个数组调用字符串都是错误的…从dialog中单击电话号码，您将在

onClick（DialogInterface dialog，int which）

回调中获得一个位置。使用如下位置：

String call=“tel:”+numbers[which]如果您觉得这对其他成员也有帮助，请向上投票。我编辑了标题，以便为这类问题找到答案。@HimanshuAgnihotri当然！同样，你也会投票回答
String call = "tel:" +numbers[which];

phone.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

             String number = "02212345678";

                          AlertDialog.Builder builder = new AlertDialog.Builder(getContext());

                builder.setItems(number , new DialogInterface.OnClickListener() {
                    @Override
