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

Intentintent=newIntent(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

p_w_picpathView.setImageBitmap(photo);

如果需要做剪切处理，就继续向下执行

3.做剪切处理

Intentintent=newIntent("com.android.camera.action.CROP"); intent.setType("p_w_picpath/*"); 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); artActivityForResult(intent,PHOTO_PICKED_WITH_DATA);

4.在onActivityResult中处理

与第二步相同。
