如何使用Android拨号程序调用以“＃”符号结尾的数字？

我的代码如下，

EditText firstNumber;
Button btnAdd;


@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main23);

    Toast.makeText(Main23Activity.this,
            "Type in your Pin Number", Toast.LENGTH_LONG).show();

    btnAdd = (Button)findViewById(R.id.button12);





    btnAdd.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            try {

                numberSign = "#";

                EditText et = (EditText) findViewById(R.id.editText6);
                String text= et.getEditableText().toString();

                Toast.makeText(Main23Activity.this,
                        "Adding Money to your account has never been this easy", Toast.LENGTH_LONG).show();

                Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:*221*" + text + numberSign  ));
                startActivity(intent);
            } catch (Exception e) {
            }
        }
    });

}

}

Answer 1

这是你使用android拨号器调用以'＃'结尾的数字的方法。您需要编码然后解析。

尝试以下代码，

String text = et.getText().toString();

Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + Uri.encode("*221*" + text + "#")));
startActivity(intent);
