DatePicker is not launching because you have not set the onClickListener for your EditText in your code.

Set the click listener as below for both your EditText.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    edt=(EditText)findViewById(R.id.editText1);
    edt2=(EditText)findViewById(R.id.editText2);   
    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Calendar c = Calendar.getInstance();
    Calendar c1=Calendar.getInstance();
    c1.setTime(new Date());
    c.setTime(new Date()); // Now use today date.
    c.add(Calendar.DATE, 7); // Adding 7 days
    String ToDate = sdf.format(c.getTime());
    String FromDate = sdf.format(c1.getTime());
    edt2.setText(FromDate);
    edt.setText(ToDate);

    edt2.setOnClickListener(new OnClickListener() {
       @Override
      public void onClick(View v) {
       selectDate(v);
        }
   });

  edt.setOnClickListener(new OnClickListener() {
       @Override
      public void onClick(View v) {
       selectDate(v); //Pass the View as parameter. 
        }
   });
}

回答2:

You just implements Edittext onClickListner onClick() Event:

edt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
               // new DatePickerDialog(ProximityActivity.this, dateD, myCalendar
                        //.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                        //myCalendar.get(Calendar.DAY_OF_MONTH)).show();

                      //Load your DiaglogFragment Over here
            }
        });

回答3:

Didn't you forget to set your onClickListener in your onCreate? Or is it handle in your xml?

edt2.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        selectDate(null);//I set null cause I don't know in the function what should the view be.
    }
});
