怪胎：Android开发ImageView图片无法显示

在Android中ImageView无法显示加载的本地SDCard图片。

具体过程是：先调用本地照相机程序摄像，然后将拍摄的图片加载在ImageView中显示。

[java] view plaincopyprint?

public class ActiEnvi extends Activity {

static final String TAG = "ActiEnvi";

private static final int REQ_CODE_CAMERA = 0x1;

private String imgpath = "";

private String tempath = "";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.acti_envi);

......

}

......

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// 拍照成功并返回

if (requestCode == REQ_CODE_CAMERA

&& resultCode == Activity.RESULT_OK) {

this.imgpath = tempath;

Bitmap bm = BitmapFactory.decodeFile(this.imgpath);

imgView.setImageBitmap(bm);

imgView.setScaleType(ScaleType.FIT_CENTER);

}

}

.......

// 调用系统相机拍照

protected void captureImage() {

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

tempath = IOHelper.generateImgPath();

File out = new File(tempath);

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));

startActivityForResult(intent, REQ_CODE_CAMERA);

}

......

}
