试图从片段中的相机拍照

我正在尝试使用手机相机拍照并将照片设置为我的布局中的imageview。我是Android的新手,我已经做过研究,但却找不到任何结论。

当我运行应用程序并点击相机按钮时,我在logcat中收到此错误:

  

android.content.ActivityNotFoundException:找不到处理Intent的活动{act = android.provider.MediaStore.IMAGE_CAPTURE}

这是我的代码中具有相机意图的部分:

public class PicOfDay extends Fragment implements View.OnClickListener {

private static final int CAMERA_REQUEST = 1888;
public ImageView picOfDay;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.pic_of_day, container, false);
    picOfDay.setOnClickListener(this);
    setHasOptionsMenu(true);
    return view;
}

private void takePhoto() {
    Intent camIntent = new Intent("android.provider.MediaStore.IMAGE_CAPTURE");
    startActivityForResult(camIntent, CAMERA_REQUEST);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        picOfDay.setImageBitmap(photo);
    }
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // Inflate the menu; this adds items to the action bar if it is present.
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_picofday, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.camera) {
        takePhoto();
        return true;
    }

    return super.onOptionsItemSelected(item);
}
}

我认为错误可能是由您使用

引起的

" IMAGE_CAPTURE"而不是" ACTION_IMAGE_CAPTURE"请尝试使用此代码:

        Intent camIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

另外(android.provider.MediaStore.Action_IMAGE_CAPTURE);不应该在引号中。见Android Docs 详情。

Intent操作错误:应该是"android.media.action.IMAGE_CAPTURE"或者@Keylwin说的,MediaStore.ACTION_IMAGE_CAPTURE(没有引号应该是一个常量值),以便直接兼容。

请阅读this

private void takePhoto() {
    Intent camIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); // "android.media.action.IMAGE_CAPTURE"
    startActivityForResult(camIntent, CAMERA_REQUEST);
}
