Question

我试图通过点击一个按钮选择两个号码来直接拨打号码，但是当我选择其中一个号码时，它会转到拨号盘屏幕但是＆＃34; Ljava。 lang.CharSequence＆＃34;写在那里，弹出一个不支持消息服务的对话框。

这是我的代码： -

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();


            }
        });

Answer 1

更改

 String call = "tel:" +numbers;

要

String call = "tel:" +numbers[which];

Answer 2

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

             String number = "02212345678";

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

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


                    }
                });
                builder.show();


            }
        });

这是一个完整的代码，用于选择数字并在按钮单击上调用所选的数字。我希望这也有助于其他成员。

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();


            }
        });

如何使用Intent.ACTION_CALL调用数字选择？
