Android DatePickerDialog

一.源码

    public DatePickerDialog(@NonNull Context context, @Nullable DatePickerDialog.OnDateSetListener listener, int year, int month, int dayOfMonth) {
        super((Context)null);
        throw new RuntimeException("Stub!");
    }
　　//int themeResId  样式
    public DatePickerDialog(@NonNull Context context, int themeResId, @Nullable DatePickerDialog.OnDateSetListener listener, int year, int monthOfYear, int dayOfMonth) {
        super((Context)null);
        throw new RuntimeException("Stub!");
    }　　

二.代码

eclipse、as 同方法也有可能不同样式，取决于清单文件

2.1.xml

2.2.eclipse

package com.gatsby.datepickerdialogtest2;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {
	private Button btn_date;
	private Button btn_ok;
	Context mContext;

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

		mContext = MainActivity.this;
		btn_date = (Button) findViewById(R.id.btn_date);
		btn_date.setOnClickListener(this);

	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch (v.getId()) {
		case R.id.btn_date:
			// 弹出对话框
			Calendar calendar = Calendar.getInstance();
			DatePickerDialog datePickerDialog = new DatePickerDialog(mContext, null, calendar.get(Calendar.YEAR),
					calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
			datePickerDialog.show();
			break;
		}
	}

}

2.3.AS 

package com.gatsby.test3;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;

import java.util.Calendar;

public class MainActivity extends Activity implements View.OnClickListener , DatePickerDialog.OnDateSetListener {


    private Button btn_date;
    private Button btn_ok;
    Context mContext;

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

        mContext = MainActivity.this;
        btn_date = (Button) findViewById(R.id.btn_date);
        btn_date.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
            case R.id.btn_date:
                // 弹出对话框
                Calendar calendar = Calendar.getInstance();
                DatePickerDialog datePickerDialog = new DatePickerDialog(mContext, 3,this, calendar.get(Calendar.YEAR),
                        calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
                datePickerDialog.show();
                break;
        }
    }

    @Override
    public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {

    }
}
