android调用照相机拍照获取照片并做简单剪裁

1.调用系统的照相机程序
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 startActivityForResult(intent, TAKE_PHOTO_WITH_DATA);

2.在onActivityResult中处理返回的data
final Bitmap photo = data.getParcelableExtra("data");
如果不需要做剪切处理就可以直接使用图片了，比如输出到ImageView上
imageView.setImageBitmap(photo);
如果需要做剪切处理，就继续向下执行

3.做剪切处理
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setType("image/*");
        intent.putExtra("data", data);
        intent.putExtra("crop", "true");
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("outputX", 128);
        intent.putExtra("outputY", 128);
        intent.putExtra("return-data", true);
startActivityForResult(intent, PHOTO_PICKED_WITH_DATA);

4.在onActivityResult中处理
与第二步相同。

完整代码：
public class SdCardUriTestActivity extends Activity {
    /** Called when the activity is first created. */
    private Button btnTake = null;
    private ImageView lblImage = null;
   
    private static final int PHOTO_PICKED_WITH_DATA = 3021;
    private static final int CAMERA_WITH_DATA = 3023;
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        btnTake = (Button)findViewById(R.id.btnTake);
        lblImage = (ImageView)findViewById(R.id.lblImage);
        btnTake.setOnClickListener(new View.OnClickListener() {
           
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, CAMERA_WITH_DATA);
            }
        });
       
    }
   
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        if(resultCode!=RESULT_OK)
            return;
        switch(requestCode){
        case CAMERA_WITH_DATA:
            final Bitmap photo = data.getParcelableExtra("data");
            if(photo!=null){
                doCropPhoto(photo);
            }
        case PHOTO_PICKED_WITH_DATA:
            Bitmap photo1 = data.getParcelableExtra("data");
            if(photo1!=null){
                lblImage.setImageBitmap(photo1);
            }
           
        }
    }
   
    protected void doCropPhoto(Bitmap data){
        Intent intent = getCropImageIntent(data);
        startActivityForResult(intent, PHOTO_PICKED_WITH_DATA);
    }
   
    public static Intent getCropImageIntent(Bitmap data) {
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setType("image/*");
        intent.putExtra("data", data);
        intent.putExtra("crop", "true");
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("outputX", 128);
        intent.putExtra("outputY", 128);
        intent.putExtra("return-data", true);
        return intent;
    }
}

布局文件略
注：1.6的sdk运行此代码会出现问题，具体原因还在调查。也希望知道原因的朋友帮帮忙。
