Android 获取图片exif信息

使用android api读取图片的exif信息

布局代码:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="read"
        android:text="读取exif信息" />


</LinearLayout>

代码如下:

package com.wuyudong.loadimage;

import java.io.IOException;

import android.app.Activity;
import android.media.ExifInterface;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends Activity {

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

    }

    public void read(View view) {
        try {
            ExifInterface exif = new ExifInterface("/sdcard/a.jpg");
            String time = exif.getAttribute(ExifInterface.TAG_DATETIME);
            System.out.println(time);
            
            String model = exif.getAttribute(ExifInterface.TAG_MODEL);
            System.out.println("model:" + model);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}

运行项目,打印如下结果:

09-04 07:51:32.561: I/System.out(11278): 2014:09:06 12:34:25
09-04 07:51:32.561: I/System.out(11278): model:GT-I8558
