android调用照相机拍照获取照片并…

1.调用系统的照相机程序
Intent intent = 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
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 = newIntent("com.Android.camera.action.CROP");
       intent.setType("image
   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 = newIntent(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");
