• Android实现拍照与打开本地图片


    代码如下:

    publicclass MainActivity extends Activity {

        private Button btnCamera;

        private Button btnLocalPic;

        private ImageView imageView;

        @Override

        protectedvoid onCreate(Bundle savedInstanceState) {

            // TODO Auto-generated method stub

            super.onCreate(savedInstanceState);

            setContentView(R.layout.mainactivity);

            btnCamera = (Button) this.findViewById(R.id.btnCamera);

            btnLocalPic = (Button) this.findViewById(R.id.btnlocalPic);

            imageView = (ImageView) this.findViewById(R.id.imageView1);

            btnCamera.setOnClickListener(new OnClickListener() {

                @Override

                publicvoid onClick(View arg0) {

                    // TODO Auto-generated method stub

                    Intent intent = new Intent(

                            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                    startActivityForResult(intent, 1000);

                }

            });

            btnLocalPic.setOnClickListener(new OnClickListener() {

                @Override

                publicvoid onClick(View arg0) {

                    // TODO Auto-generated method stub

                    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

                    intent.setType("image/*");

                    intent.putExtra("crop", true);

                    intent.putExtra("return-data", true);

                    startActivityForResult(intent, 1001);

                }

            });

        }

        @Override

        protectedvoid onActivityResult(int requestCode, int resultCode, Intent data) {

            // TODO Auto-generated method stub

            super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == 1000 && resultCode == RESULT_OK) {

                Bundle bundle = data.getExtras();

                Bitmap bm = (Bitmap) bundle.get("data");

                imageView.setImageBitmap(bm);

            } elseif (requestCode == 1001 && resultCode == RESULT_OK) {

                Uri uri = data.getData();

                ContentResolver contentResolver = getContentResolver();

                try {

                    Bitmap bm = BitmapFactory.decodeStream(contentResolver

                            .openInputStream(uri));

                    imageView.setImageBitmap(bm);

                } catch (Exception e) {

                    // TODO: handle exception

                    e.printStackTrace();

                }

            }

        }

    }
