如何让时间选择器在android中只显示24小时的时间格式

import android.app.TimePickerDialog;
import android.content.Context;
import android.widget.TimePicker;

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    private Context mContext;
    private DateFormat mTimeFormat;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mContext = this;
        mTimeFormat = new SimpleDateFormat("HH:mm");

        // 点击按钮弹出时间选择器
        Button timeButton = findViewById(R.id.timeButton);
        timeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showTimePickerDialog();
            }
        });
    }

    private void showTimePickerDialog() {
        Calendar calendar = Calendar.getInstance();
        int hour = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);

        TimePickerDialog timePickerDialog = new TimePickerDialog(mContext, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                // 格式化为24小时制的时间字符串
                String formattedTime = formatTime(hourOfDay, minute);
                // 将时间设置给需要显示时间的控件
                TextView timeTextView = findViewById(R.id.timeTextView);
                timeTextView.setText(formattedTime);
            }
        }, hour, minute, true);

        timePickerDialog.show();
    }

    private String formatTime(int hour, int minute) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, hour);
        calendar.set(Calendar.MINUTE, minute);
        return mTimeFormat.format(calendar.getTime());
    }
}
