如果照相之后要添加裁剪：

class TakePicture implements OnClickListener{

public void onClick(View v) {
takePic();

File picture = new File("/sdcard/picture.jpg");
Intent intent = new Intent("com.android.camera.action.CROP");

/**************如果不加这句话，会报错，找不到裁剪的Activity******/
intent.setDataAndType( Uri.fromFile(file)，"image/*);

/********************************************************************************/

intent.putExtra("crop", "true");
intent.putExtra("aspectX", 3);
intent.putExtra("aspectY", 2);
intent.putExtra("outputX",384 );
intent.putExtra("outputY", 256);
intent.putExtra("return-data", true);
startActivityForResult(intent, OVER);
finish();
}
}
