请耐心等待，因为这是我的第一个应用程序。我的应用程序不是太具有革命性，但我想通过实现一些自定义选择器使其更加用户友好。例如，使用日历 View 的日期选择器或水平流动的类似微调器的选择器(很像 SetCPU)。不幸的是，我什至不知道从哪里开始构建像这样的自定义 ui 组件。

最佳答案

我想下面的框架代码将有助于在您的应用程序中提供您想要的一些灵 active 。

 /* Simple Dialog

                    Dialog dialog = new Dialog(this);
                    dialog.setTitle("Hello");
                    dialog.show();
      */

    /*    Inflating an layout as the Dialog

                    Dialog loginDialog = new Dialog(this);
                    View layout = LayoutInflater.from(this).inflate(R.layout.login, null);
                    loginDialog.setContentView(layout);
                    Button btn = (Button)(layout.findViewById(R.id.button1));
                    final EditText txt = (EditText) layout.findViewById(R.id.editText1);

                    btn.setOnClickListener(new View.OnClickListener() {

                        public void onClick(View v) {
                            // TODO Auto-generated method stub
                            //Toast.makeText(getApplicationContext(), txt.getText().toString(), Toast.LENGTH_SHORT).show();
                            txt.setText("Ahmedabad");
                        }
                    });
                    loginDialog.show();

            /* ProgreessBar Dialog (you need to implement thread)

        ProgressDialog dialog = new ProgressDialog(this);
                    dialog.setProgressStyle(2);

                    dialog.show();
    */


       /* Alert Dialog to alert a mesage or an error or customize exception like Enter the field, etc.

                AlertDialog dialog = new AlertDialog.Builder(this).create();
                    dialog.setMessage("Message");
                    dialog.setIcon(R.drawable.ic_launcher);
                    dialog.setTitle("Done");
                    dialog.show();
    */


/* ------------------- Binding array items into the spinner ---------------------------

        sp = (Spinner)findViewById(R.id.spinner1);
        String bloodgroups[]={
            "A +ve","B +ve","O +ve","AB +ve","A -ve","B -ve","O -ve","AB -ve"
        };
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout .simple_spinner_dropdown_item,bloodgroups); 
        sp.setAdapter(adapter);

*/

/* DatePicker Dialog Code: I have used a button whose click event bring datepicker dialog into focus

 Button btnselDate = (Button)findViewById(R.id.btnseldate); // date select button

// ----------------------------- DATE PICKER DIALOG PROMPT ---------------------
        btnselDate.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            // TODO Auto-generated method stub
                showDialog(1);
            }
        });

 @Override
     protected Dialog onCreateDialog(int id) {
         DatePickerDialog dialog = new DatePickerDialog(this, new OnDateSetListener()
         {
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
            {
                ((EditText)findViewById(R.id.txtdate)).setText(dayOfMonth + "/" + monthOfYear + "/" + year);
            }           
         }, new GregorianCalendar().get(Calendar.YEAR), new GregorianCalendar().get(Calendar.MONTH), new GregorianCalendar().get(Calendar.DAY_OF_MONTH));
        return dialog;
     }
