DatePicker与TimePicker的使用
Android开发中经常会使用到日期选择器与时间选择器，接下来我就来总结一下
效果图：
先贴一下项目结构图：

import android.widget.Toast;
public class MainActivity extends Activity implements View.OnClickListener {
private RelativeLayout mRlSelectDate, mRlSelectTime;
private TextView mTvSelectDate, mTvSelectTime;
private Context mContext;
private static int SELECTDATE = 0, SELECTTIME = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = this;
bindView();
}
private void bindView() {
mRlSelectDate = (RelativeLayout) findViewById(R.id.rl_select_date);
mRlSelectTime = (RelativeLayout) findViewById(R.id.rl_select_time);
mTvSelectDate = (TextView) findViewById(R.id.tv_select_date);
mTvSelectTime = (TextView) findViewById(R.id.tv_select_time);
mRlSelectDate.setOnClickListener(this);
mRlSelectTime.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.rl_select_date:
startActivityForResult(new Intent(mContext,
DatePickerActivity.class), SELECTDATE);
break;
case R.id.rl_select_time:
if (TextUtils.isEmpty(mTvSelectDate.getText().toString().trim())) {
Toast.makeText(mContext, "请先选择请假开始日期", Toast.LENGTH_LONG);
} else {
startActivityForResult(new Intent(mContext,
TimePickerActivity.class), SELECTTIME);
}
break;
default:
break;
}
}
/**
* 方法名: onActivityResult
* 方法描述: 回传数据
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MainActivity.SELECTDATE
&& resultCode == RESULT_OK) {// 选择日期
String startDate = data.getStringExtra("date");
mTvSelectDate.setText(startDate);
} else if (requestCode == MainActivity.SELECTTIME
&& resultCode == RESULT_OK) {// 选择时间
String leaveStartTime = data.getStringExtra("hourOfDay") + ":"
+ data.getStringExtra("minute");
mTvSelectTime.setText(leaveStartTime);
}
}
}
