如何使用 Intent.ACTION_CALL 选择要呼叫的号码？

Question

我试图通过单击按钮提供两个号码的选项以直接拨打该号码，但是当我选择其中一个号码时，它会转到拨号器屏幕，但写入了“Ljava.lang.CharSequence”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

改变

 String call = "tel:" +numbers;

到

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();


            }
        });

这是用于在按钮单击时选择号码和呼叫所选号码的完整代码。 我希望这也能帮助其他成员。

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();


            }
        });
