寒假每日日报47（开发家庭记账本APP——进度八）

今天将时间这一个功能给写一下，点击输入时间的文本框，会弹出一个日历

AddActivity.java代码如下：

public class AddActivity extends AppCompatActivity {

    //账单时间
    private EditText medittime;

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

        //时间
        medittime = findViewById(R.id.edittime);
        medittime.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    showDataPickDlg();
                    return true;
                }
                return false;
            }
        });
        medittime.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    showDataPickDlg();
                }
            }
        });

}
//时间
    protected void showDataPickDlg(){
        Calendar calendar=Calendar.getInstance();
        DatePickerDialog dataPickerDialog=new DatePickerDialog(AddActivity.this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                AddActivity.this.medittime.setText(year+"-"+(month+1)+"-"+dayOfMonth);
            }
        },calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
        dataPickerDialog.show();
    }
