日期选择器DailLog提示框

1.封装好的，直接复制下来就可以用了，先看下封装好的工具类

import android.annotation.SuppressLint;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.DatePicker;
import android.widget.LinearLayout;
import android.widget.TextView;

import java.util.Calendar;

/**

 */
public class DailLogUtlis {
    private Calendar calendar; // 通过Calendar获取系统时间
    private Context context;

    public DailLogUtlis(Context context) {
        this.context = context;


    }

    @SuppressLint("NewApi")
    public void setDate(final TextView text) {
        calendar = Calendar.getInstance();
        // 通过自定义控件AlertDialog实现
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        View view = (LinearLayout) LayoutInflater.from(context).inflate(
                R.layout.dialogdata_itme, null);
        final DatePicker datePicker = (DatePicker) view
                .findViewById(R.id.date_picker);
        // 设置日期简略显示 否则详细显示 包括:星期周
        datePicker.setCalendarViewShown(false);
        // 初始化当前日期
        calendar.setTimeInMillis(System.currentTimeMillis());
        datePicker.init(calendar.get(Calendar.YEAR),
                calendar.get(Calendar.MONTH),
                calendar.get(Calendar.DAY_OF_MONTH), null);
        // 设置date布局
        builder.setView(view);
        builder.setTitle("请选择日期:");
        builder.setNegativeButton("确 定",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // 日期格式
                        StringBuffer sb = new StringBuffer();
                        sb.append(String.format("%d-%02d-%02d",
                                datePicker.getYear(),
                                datePicker.getMonth() + 1,
                                datePicker.getDayOfMonth()));
                        text.setText(sb);
                        dialog.cancel();
                    }
                });

        builder.setPositiveButton("取 消",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });
        builder.create().show();
    }
}

2.自定义dialog布局 –一下代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <DatePicker
        android:id="@+id/date_picker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_marginLeft="20dp"
        android:layout_marginTop="5dip"
        android:calendarViewShown="false"
        android:datePickerMode="spinner" />
</RelativeLayout>

3.在MainAcitivity中直接调用就行，简单

import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity  {
    private Context context=this;
    private Button button;
    private TextView dateTxt;

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

        button= (Button) findViewById(R.id.button);
        dateTxt= (TextView) findViewById(R.id.dateTxt);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DailLogUtlis dailLogUtlis=new DailLogUtlis(context);
                dailLogUtlis.setDate(dateTxt);
            }
        });
    }
}
