iv = (ImageView) findViewById(R.id.iv);
}

public void btn(View view) {    switch (view.getId()){        case R.id.button:            //跳转到拍照的意图            Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);            //判断系统中是否有照相机            if (takePhotoIntent.resolveActivity(getPackageManager())!=null){                startActivityForResult(takePhotoIntent,TAKE_PHOTO);            }            break;    }}/** * 处理数据 * @param requestCode * @param resultCode * @param data */@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    //判断请求码和返回码    if (requestCode==TAKE_PHOTO&&resultCode==RESULT_OK){        Bitmap bitmap = data.getParcelableExtra("data");        iv.setImageBitmap(bitmap);    }}
