Answer 1

将您的 showSelectedNumber 方法更改为:

public void showSelectedNumber(int type, String number) {
    // Toast.makeText(this, type + ": " + number, Toast.LENGTH_LONG).show(); 
    // txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo2);
    if(txtPhoneNo != null && txtPhoneNo.getText().toString().length()==0)
         txtPhoneNo.setText(number);
    else
         if(txtPhoneNo != null) txtPhoneNo.append(","+number);

}
