1.佈局一個按鈕，用於啟動時間選擇器

<?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="zs.recyclerviewdemo.ChooseTimeActivity">
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="00:00"
        android:id="@+id/btnTime"/>
</LinearLayout>
 

2.在Activity中啟用時間選擇器

public class ChooseTimeActivity extends AppCompatActivity {

private Button btnTime;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_choose_time);
    btnTime = (Button)findViewById(R.id.btnTime);
    btnTime.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new TimePickerDialog(ChooseTimeActivity.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    String time = hourOfDay + ":" + minute;
                    btnTime.setText(time);
                }
            },0,0,true).show();//true為24小時格式，flase為12小時格式
        }
    });
}
}
