Android控件TimePickerDialog的使用

1.简介

TimePickerDialog是用于显示日期的对话框，使用也很简单。下面是使用的例子。

Calendar calendar = Calendar.getInstance();
//第一个参数表示设备上下文 第二个参数表示监听器（实现TimePickerDialog.OnTimeSetListener接口） 最后一个参数表示是否24小时制
TimePickerDialog timePickerDialog = new TimePickerDialog(TimePickerDialogActivity.this, TimePickerDialogActivity.this,
calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE), true);
imePickerDialog.show();

2.使用例子

创建TimePickerDialogActivity，代码如下。

1. activity_time_picker_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".TimePickerDialogActivity"
    android:orientation="vertical"
    android:padding="10dp">

    <Button
        android:text="弹出时间选择对话框"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/btn_pop_time_picker_dialog"/>
</LinearLayout>

2. TimePickerDialogActivity.java

package xyz.strasae.androidlearn.senior;

import androidx.appcompat.app.AppCompatActivity;

import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.TimePicker;
import android.widget.Toast;

import java.util.Calendar;

public class TimePickerDialogActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_time_picker_dialog);
        findViewById(R.id.btn_pop_time_picker_dialog).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Calendar calendar = Calendar.getInstance();
                //最后一个参数表示是否24小时制
                TimePickerDialog timePickerDialog = new TimePickerDialog(TimePickerDialogActivity.this, TimePickerDialogActivity.this,
                        calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE), true);
                timePickerDialog.show();
            }
        });
    }

    @Override
    public void onTimeSet(TimePicker timePicker, int i, int i1) {
        Toast.makeText(this, "你选择的时间是" + i + ":" + i1, Toast.LENGTH_SHORT).show();
    }
}
