Android TimePickerDialog ( 时间选择对话框 ) 会弹出一个对话框形式的时间选择器

TimePickerDialog

TimePickerDialog 跟 DatePickerDialog 一样，几乎方法和属性都一样，创建方法也一样

可以通过实例化 DatePickerDialog 来创建，然后调用 show() 方法来创建

TimePickerDialog(Context context, TimePickerDialog.OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView)

TimePickerDialog(Context context, int themeResId, TimePickerDialog.OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView)

几个方法循序渐进，各个参数说明如下

接下来我们就来创建一个 TimePickerDialog

先来看看最后效果

1. 创建一个 空的 Android 项目 cn.twle.android.TimePickerDialog

2. 修改 activity_main.xml 创建一个按钮弹出 TimePickerDialog

   <?xml version="1.0" encoding="utf-8" ?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:padding="16dp"
       android:orientation="vertical" >
   
       <Button 
           android:id="@+id/btn_pop"
           android:text="弹出时间选择器"
           android:layout_width="wrap_content" 
           android:layout_height="wrap_content" />
   
   </LinearLayout>
   

3. 修改 MainActivity.java

   package cn.twle.android.timepickerdialog;
   
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   
   import android.widget.Button;
   import android.view.View;
   
   import android.widget.Toast;
   import android.widget.TimePicker;
   import android.app.TimePickerDialog;
   
   import java.util.Calendar;
   
   public class MainActivity extends AppCompatActivity implements View.OnClickListener{
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
   
           Button btn_pop = (Button) findViewById(R.id.btn_pop);
           btn_pop.setOnClickListener(this);
       }
   
       @Override
       public void onClick(View v) {
   
           switch (v.getId()){
               case R.id.btn_pop:
                   Calendar cale2 = Calendar.getInstance();
                   new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
                       @Override
                       public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
   
                           Toast.makeText(getApplicationContext(), "您选择的时间是:"+hourOfDay+"时"+minute+"分", Toast.LENGTH_SHORT).show();
                       }
                   }, cale2.get(Calendar.HOUR_OF_DAY), cale2.get(Calendar.MINUTE), true).show();
                   break;
           }
       }
   }
