android中调用系统拍照功能并显示拍照的图片

如果你是拍照完，利用onActivityResult获取data数据，把data数据转换成Bitmap数据，这样获取到的图片，是拍照的照片的缩略图

代码如下：

[html]
package com.example.myphotos;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
