今天學TimePicker

TimePicker 是一個可以用來選擇時間的控件
用法蠻像DatePicker的:)

public class TimePickerActivity extends AppCompatActivity implements View.OnClickListener, TimePickerDialog.OnTimeSetListener {

    private TimePicker tp_time;
    private TextView tv_time;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_time_picker);
        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
            Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
            return insets;
        });
        findViewById(R.id.btn_ok).setOnClickListener(this);
        findViewById(R.id.btn_time).setOnClickListener(this);
        tp_time = findViewById(R.id.tp_time);
        tp_time.setIs24HourView(true);
        tv_time = findViewById(R.id.tv_time);

    }

    @Override
    public void onClick(View view) {
        if(view.getId() == R.id.btn_ok){
            String desc = String.format("您選擇的時間是%d時%d分",tp_time.getHour(),tp_time.getMinute());
            tv_time.setText(desc);
        } else if (view.getId() == R.id.btn_time) {
            Calendar calendar = Calendar.getInstance();
            TimePickerDialog dialog = new TimePickerDialog(this, android.R.style.Theme_Holo_Light_Dialog,this,calendar.get(Calendar.HOUR_OF_DAY),calendar.get(Calendar.MINUTE),true);
            dialog.show();
        }
    }

    @Override
    public void onTimeSet(TimePicker timePicker, int i, int i1) {
        String desc = String.format("您選擇的時間是%d時%d分",i,i1);
        tv_time.setText(desc);
    }
}
