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:
