当我单击编辑文本时.....我得到了 logcat 中的错误

DatePickerDate.java

public class DatePickerDate extends FragmentActivity {

    EditText mEdit;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.search_page);
    }

    public void selectDate(View view) {
        DialogFragment newFragment = new SelectDateFragment();
        newFragment.show(getSupportFragmentManager(), "DatePicker");
    }
    public void populateSetDate(int year, int month, int day) {
        mEdit = (EditText)findViewById(R.id.DATE_EDIT_TEXT_ID);
        mEdit.setText(month+"/"+day+"/"+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, mm+1, dd);
        }
    }

}

如何解决这个问题！

搜索页面.java

公共类 SearchPage 扩展 Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.search_page);

}


}

我猜您的 SearchPage 活动中没有以下方法

 public void selectDate(View view) {
      }

那就是造成问题。

因为SearchPage也用到了你的search_page布局，所以也需要有selectDate(View)方法。

当单击 View with 时android:onClick="selectDate"，Android 将调用selectDate(View)当前显示给用户的 Activity。

在您的情况下，显示的是Activity，并且应用程序崩溃，因为 Android在该 Activity 中SearchPage找不到。selectDate(View)因此你的 logcat 的第一行，

在活动类 com.project.findmybuffet.SearchPage 中找不到方法 selectDate(View)
