Android 调用系统照相程序并显示 各位高手帮我看看为什么出现这样的问题

public class XinghuoActivity extends Activity {
ImageView image;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == Activity.RESULT_OK) {
// 拍照Activity保存图像数据的key是data，返回的数据类型是Bitmap对象
Bitmap cameraBitmap = (Bitmap) data.getExtras().get("/sdcard/rtest.jpg");
// 在ImageView组件中显示拍摄的照片
image.setImageBitmap(cameraBitmap);
}
} super.onActivityResult(requestCode, resultCode, data);
}

Answer 1

data.getExtras().get("/sdcard/rtest.jpg")这里错了，取得图片应该是data.getExtras().get("data")，在调用时并没有把图片存到/sdcard/rtest.jpg这个文件中。
