Android自定义相机SurfaceView OnClick将图像保存在SD卡上？

Question

嗨，我想实现自定义安卓相机应用程序，其中包括imageview在相机preview.After点击屏幕后，我想存储在SD卡中的图像。到目前为止我已经完成了这部分。但我不能点击SurfaceView和保存image.Can任何人都可以告诉我如何解决我的问题。到目前为止，它打开相机，它具有imageview顶部的相机。但onclick方法不工作。并且任何人都可以告诉我如何保存图像时调用onclick函数。这是mycode。

这是mainlayout

<?xml version="1.0" encoding="utf-8"?> 

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

    <SurfaceView 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:id="@+id/surfaceView" 
      android:layout_gravity="center"/> 
</LinearLayout> 

这是自定义视图（activity_camera）

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:orientation="vertical" 
       android:layout_width="fill_parent" 
       android:layout_height="fill_parent" 
       android:gravity="bottom" 
     > 

    <ImageView 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:src="@drawable/border" 
      android:id="@+id/imageView"/> 
</LinearLayout> 

这是Java代码。

capture.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     camera.takePicture(null,null, jpegCallback); 
    } 
}); 

final Camera.PictureCallback jpegCallback = new Camera.PictureCallback() { 
    public void onPictureTaken(byte[] data, Camera camera) { 
     FileOutputStream outStream = null; 
     try { 
      outStream = new FileOutputStream(String.format("/sdcard/YourImage.jpg")); 
      outStream.write(data); 
      outStream.close(); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
     } 
     camera.startPreview(); 
    } 
};
