调用手机相机拍照并裁剪相片

      

一、调用相机拍照，并返回照片，但是照片缩略图而不是原图，如果想获取原图见下一篇博客拍照和从相册中选取照片，并保存到SD卡上

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
               startActivityForResult(intent, TAKE_PHOTO_WITH_DATA);

        在onActivityResult获取得到的照片并设置给ImageView

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap photo = data.getParcelableExtra("data");
iv.setImageBitmap(photo);
}

二、使用手机拍照并缩放相片部分源码   

 private static final int CROP_PHOTO_WITH_DATA = 0;
private static final int SCALE_PHOTO_WITH_DATA = 1;


private ImageView iv;


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
iv = (ImageView) findViewById(R.id.iv_photo);
}


public void takePhoto(View v) {


Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, CROP_PHOTO_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 CROP_PHOTO_WITH_DATA:
       final Bitmap photo = data.getParcelableExtra("data");
       if(photo!=null){
           doCropPhoto(photo);
       }
   case SCALE_PHOTO_WITH_DATA:
       Bitmap scalePhoto = data.getParcelableExtra("data");
       if(scalePhoto!=null){
        iv.setImageBitmap(scalePhoto);
       }
      
   }
}


protected void doCropPhoto(Bitmap data){
   Intent intent = getCropImageIntent(data);
   startActivityForResult(intent, SCALE_PHOTO_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;
}
