保存/ Android中

Question

重命名SD卡上拍摄的照片我用从下面的链接代码，是非常有益的，谢谢： http://www.tutorialforandroid.com/2010/10/take-picture-in-android-with.html

需要一些照片的问题帮助！ takePhoto（）启动MediaStore.ACTION_IMAGE_CAPTURE，getFile（）创建“Image Keeper”目录，然后在“Image-SOMENUMBER.jpg”名称下保存拍摄的图片在onActivityResult（）中我想将拍摄的图片显示为ImageView，喜欢将图片重命名为用户在edittext或其他内容中的输入内容！

有两个问题：

1）为什么我不能得到的ImageView表明我在尝试{}部分图片？我究竟做错了什么？我怎样才能获得保存图像的路径？

2）是否有办法可以让用户命名的照片，他们希望的方式？（类似“另存为”或重命名上的一些按钮点击等。）

任何想法是值得欢迎的！谢谢！

这里是代码：

private static final int TAKE_PHOTO_CODE = 1; 

private void takePhoto(){ 
    final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getFile(this))); 
    startActivityForResult(intent, TAKE_PHOTO_CODE); 
} 

private File getFile(Context context){ 

    final File path = new File(Environment.getExternalStorageDirectory(), "Image keeper"); 
    if(!path.exists()){ 
    path.mkdir(); 
    } 
    String name; 
    int n = 100000; 
    int rand; 
    rand = new Random().nextInt(n); 
    name = "Image-" + rand + ".jpg"; 
    File file = new File(path,name); 

    return file; 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == RESULT_OK) { 
     switch(requestCode){ 
     case TAKE_PHOTO_CODE: 
     final File file = getFile(this); 
     try { 
      Bitmap captureBmp; 
      captureBmp = Media.getBitmap(getContentResolver(), Uri.fromFile(file)); 

      iv = (ImageView) findViewById(R.id.imageView1); 
      iv.setImageBitmap(captureBmp); 

     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     break; 
    } 
    } 
}

没能解决重命名我的问题的一部分，但是这一段代码做工作给我！我敢肯定，它可以做得更有趣，但它的工作原理！它涉及拍照，保存到SD卡并获得路径！

ImageView iv; 
static File image; 
Uri ImageUri; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    Button btn = (Button) findViewById(R.id.button1); 

    btn.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 

     takePhoto(); 

    } 
}); 
} 

private static final int TAKE_PHOTO_CODE = 1; 

private void takePhoto(){ 
    image = getFile(this); 
    final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(image)); 
    startActivityForResult(intent, TAKE_PHOTO_CODE); 
} 

private File getFile(Context context){ 

    final File path = new File(Environment.getExternalStorageDirectory(), "Image keeper"); 
    if(!path.exists()){ 
    path.mkdir(); 
    } 
    String name; 
    int n = 100000; 
    int rand; 
    rand = new Random().nextInt(n); 
    name = "Image-" + rand + ".jpg"; 
    File fileimage = new File(path, name); 

    return fileimage; 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == RESULT_OK) { 
     switch(requestCode){ 
     case TAKE_PHOTO_CODE: 

     try { 
      Bitmap captureBmp; 
      captureBmp = Media.getBitmap(getContentResolver(), Uri.fromFile(image)); 

      ImageUri = Uri.fromFile(image); 
      String pathToImage = ImageUri.getPath(); 

      iv = (ImageView) findViewById(R.id.imageView1); 
      iv.setImageBitmap(captureBmp); 

     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     iv.setScaleType(ImageView.ScaleType.CENTER_INSIDE); 
     iv.setAdjustViewBounds(true); 

     break; 
    } 
    } 
}
