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
