Question

我想在TimePicker上禁用键盘输入。你有想法解决这个问题吗？因为它很烦人。

提前致谢！

顺便说一下，我尝试了这个非常受欢迎的解决方案setDescendantFocusability(TimePicker.FOCUS_BLOCK_DESCENDANTS);，但它对我的代码无效。

这是我的代码;

MainActivity.java

 public void selectTimeToDisplay(View view) {
    DialogFragment dialogFragment = new DisplayTimeFragment();
    dialogFragment.show(getSupportFragmentManager(), "DatePicker");
}

public class DisplayTimeFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        final Calendar c= Calendar.getInstance();
        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);
        return new TimePickerDialog(getActivity(), this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));

    }
    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        view.setDescendantFocusability(TimePicker.FOCUS_BLOCK_DESCENDANTS);//doesnt work
        setSelectedTime(hourOfDay,minute);

    }
    public void setSelectedTime(int hourOfDay,int minute) {


         saat1.setText(hourOfDay+":"+minute);}

activity_main.xml中

<EditText
    android:layout_width="70dp"
    android:layout_height="wrap_content"
    android:inputType="time"
    android:ems="10"
    android:id="@+id/bolme1saat"
    android:layout_gravity="center_horizontal"
    android:onClick="selectTimeToDisplay"
    android:layout_above="@+id/textView4"
    android:layout_alignStart="@+id/bolme2saat"/>

Answer 1

如果您不在此课程中使用键盘，则只需禁用键盘

即可

  <activity android:name=".MainActivity" 
          android:windowSoftInputMode="stateHidden" />

替代方案可以强制android隐藏键盘

    // This works 100%

    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

您可以在xml中尝试android：focusable =“false”和android：clickable =“true”。
