• 当我点击编辑文本时 android:id="@+id/DATE_EDIT_TEXT_ID" 应该启动的日期选择器
• 但是发生的事情是我点击屏幕日期选择器的任何地方 正在启动

如何解决这个问题

Answer 1

// try this
public class SearchPage extends FragmentActivity {

    EditText mEdit;
    DialogFragment newFragment;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.search_page);
        mEdit = (EditText)findViewById(R.id.DATE_EDIT_TEXT_ID);
        newFragment = new SelectDateFragment();
        mEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
               newFragment.show(getFragmentManager(), "DatePicker");
            }
        });
    }

    public void populateSetDate(int year, int month, int day) {
        mEdit.setText(day+"/"+month+"/"+year);
    }
    public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            final Calendar calendar = Calendar.getInstance();
            int yy = calendar.get(Calendar.YEAR);
            int mm = calendar.get(Calendar.MONTH);
            int dd = calendar.get(Calendar.DAY_OF_MONTH);
            return new DatePickerDialog(getActivity(), this, yy, mm, dd);
        }

        public void onDateSet(DatePicker view, int yy, int mm, int dd) {
            populateSetDate(yy, dd, mm+1);
        }
    }

}
